Age of the Earth — Evidence from Science
Everything in this page is linked-to in Age of the Earth - Science Evidence — it's a summary of each topic that I suggest you read first (to get a "big-picture overview") before you continue reading in this page to get more details — and all except the first part (Multiple Independent Confirmations) are in the section for TOPICS where you can find other pages, including longer pages and additional young-earth responses, plus whole pages so you can see "the rest of the story" when, to reduce the amount of reading, I've "cut" parts of a page in what you see below. This page is intended to provide a relatively quick overview of some scientific evidence (a very small fraction of it) supporting an old-earth conclusion.

A Wide Variety of Abundant
Evidence
Young-earth "flood geology" theories,
which propose that a global flood produced most of the earth's geology and
fossil record, lead to theory-based explanations that seem incorrect — because
they are not consistent with what we observe — for geological formations,
and the spatial arrangement (both vertically and horizontally) of plant and
animal fossils
within this
geological
record. Although
young-earth science makes some valid claims for the geological importance
of catastrophic events, this does not contradict the old-earth theories of
modern geology, which propose a combination of slow-acting uniformitarian
processes and fast-acting catastrophic events such as volcanoes,
earthquakes, and floods.

of catastrophic events, this does not contradict the old-earth theories of

processes and fast-acting catastrophic events such as volcanoes,

Evidence from a wide range
of fields — including the study of sedimentary rocks, coral reefs,
the fossil record in geological context, biogeographical patterns in
fossils, seafloor spreading and continental drift, magnetic
reversals, genetic
molecular clocks, radioactive dating, the development of stars,
starlight
from faraway galaxies, and more — indicates that the earth and
universe are billions of years old.
The Principle of Multiple
Independent Confirmations
Because "a long time" is an
essential component of many theories that in other ways (such as the domains
they explain and the components they include) are relatively independent,
it is less likely that suspicions of circular reasoning are justified. With
this independence, the old-earth evidence is not like a "house of cards" where
if one part falls it all falls. It is more like a strong house with
a ceiling supported in many ways: by concrete walls reinforced by steel
rods, plus granite pillars, wood beams,... Each support would be
sufficient by itself, but when combined the support is even stronger. The
young-earth task of pulling down the "old-earth house" would require discarding
much of modern science. This isn't likely to happen, nor does it
seem to be a desirable goal.
This principle of multiple
independent confirmations is an essential part of scientific method. Its
reliability, as an indicator of probable truth, is confirmed by logic
and also by its excellent "track record" in the history
of science. This powerful principle of science has convinced
almost all scientists that the earth and universe are extremely old,
and that scientific evidence-and-logic provides very strong support
for this conclusion.
• Coral and the Moon
by Don Lindsay
The Moon causes tides. Tides make the Earth slightly asymmetrical,
and one result is that the Earth's rotational energy is slowly being
stolen by the Moon. We spin more slowly: and the Moon rises to a
higher, slower orbit.
This was worked out mathematically in the 1800's. Today, however,
it has been measured.
One consequence is that in the future, there will be fewer days in
a year. And in the past, there would have been more.
Modern corals deposit a single, very thin layer of lime once a
day. It is possible to count these diurnal (day-night)
growth lines. You can also count annual growth. So, given the right
piece of coral, you can measure how many days there are in a year.
These measures can equally well be done on fossilized coral. For
example, coral from the Pennsylvanian rockbeds have about 387 daily
layers per year. Coral from the Devonian rockbeds have about 400
daily layers per year. In the Cambrian, a year was 412 days. One
Precambrian stromatolite gave 435 days per year.
With bivalves, you can count days and lunar months. Recent
bivalves give 29.5 days per lunar month; Pennsylvanian give 30.2;
Devonian give 30.5.
If you care, there are a lot more details about coral. There's a reading list at the rear
of that, and the topic is covered in Strahler, and the [old earth] Creationist Daniel Wonderly has written about
it. But there are also some broader issues.
For one, do all these numbers increase, as one goes to supposedly
older and older layers of the "geologic column"? The answer is yes.
For another, are these numbers the same, if one takes corals from
different continents, but in the "same" rock layer? The answer is yes.
For a third, do these numbers agree with the theoretical numbers
that the astronomers had in hand? In order to tell, we need to use
radioactive dating techniques, to get dates for the various rocks. [and again, the answer is yes] So, the comparison is somewhat a test of
radioactive dating.

FOSSIL PATTERNS in the Geological Record — Part 1
• Rebuttals of Creationist Claims — 4 pages (in a series with hundreds) edited by Mark Isaak for Talk Origins
The sub-sections below examines young-earth proposals (in theories of flood geology) for mechanisms to explain fossil patterns; each sub-section contains the full text of the original pages (to see them, begin here and click Next Claim for Claims 2-4) but the originals also include links & references.
Ecological Zonation
Claim 1: Patterns of fossil deposition in Noah's Flood can be explained by
ecological zonation. The lower strata, in general, would contain animals
that lived in the lower elevations. Thus, marine invertebrates would be
buried first, then fish, then amphibians and reptiles (who live at the
boundaries of land and water), and finally mammals and birds. Also,
animals would be found buried with other animals from the same
communities. / Source: Morris, Henry M., 1974. Scientific Creationism, Green Forest, AR: Master
Books, pp. 118-120.
Response:
1. The fossil record does not show such a pattern of organisms sorted
ecologically:
Many animals that appear in the lower strata appear in all strata,
even recent ones. Corals and clams, for example, appear at all
levels.
Whales do not appear until much later than fish, despite living in
the same ecological zones.
Birds do not appear until after flying reptiles.
Dinosaurs consistently appear in strata before modern land animals.
Grasses live in virtually all land areas, but they appear in the
geological record only near the top, long after other land animals
and plants.
2. Even if ecological zonation could explain how deeply various faunal
zones are buried, it does not explain how they came to be buried atop
one another. How did a terrestial ecology come to be transported on
top of a marine ecology, such that fine details such as footprints,
burrows, and paleosols were undisturbed and such that the layer
extends over hundreds of square miles? How did many such layers get
stacked on top of each other? Ecological zonation implies that the
ecological zones got buried in place. What we see is ecological zones
forming and living for awhile on top of the fossils of older ecological
zones, repeatedly.
3. Fossil strata often appear in orders that contradict ecological
zonation (and other flood deposition explanations). For example, North
American midcontinent outcrops record at least fifty-five cycles of
marine inundation and withdrawal (Boardman and Heckel 1989; Heckel
1986). That is, marine ecologies are interleaved with terrestrial
ecologies.
Hydrologic Sorting
Claim 2: The order of fossils deposited by Noah's Flood, especially those of marine
organisms, can be explained by hydrologic sorting. Fossils of the same
size will be sorted together. Heavier and more streamlined forms will be
found at lower levels. / Source: Whitcomb, John C. Jr. and Henry M. Morris, 1961. The Genesis Flood.
Philadelphia, PA: Presbyterian and Reformed Publishing Co., pp. 273-274
Response:
1. Fossils are not sorted according to hydrodynamic principles.
Ammonites, which are buoyant organisms similar to the chambered
nautilus, are found only in deep strata. Turtles, which are rather
dense, are found in middle and upper strata. Brachiopods are very
similar to clams in size and shape, but brachiopods are found mostly in
lower strata than are clams. Most fossil-bearing strata contain
fossils of various sizes and shapes. Some species are found in wide
ranges, while others are found only in thin layers within those ranges.
Hydrologic sorting can explain none of this.
2. The sediments in which fossils are found are not hydrologically sorted.
Coarse sediments are often found above fine sediments. Nor are the
sediments sorted with the fossils. Large fossils are commonly found in
fine sediments.
3. A catastrophic flood would not be expected to produce much hydrologic
sorting. A flood that lays down massive quantities of sediments would
jumble up most of them.
Fossil Sorting by Fleeing
Claim 3: The order of fossils in the fossil record is explained by the animals'
ability to escape the rising floodwaters. Slow animals, such as clams,
are found low in the fossil record, while quicker animals, such as mammals
and birds, appear higher. / Source: Morris, Henry M., 1974. Scientific Creationism, Green Forest, AR: Master
Books, p. 119.
Response:
1. Fossils are not sorted according to their ability to escape rising
floodwaters. If they were, we would expect to see slow-moving species
like sloths and tortoises and every low-elevation plant at the bottom
of the fossil record, while fast-moving species, such as velociraptors,
pterosaurs, and giant dragonflies, would be at the top. But this is
nothing like what we actually observe; in many cases we find just the
opposite. For example, in undisturbed strata there has not
been a single sloth fossil found below even the highest velociraptor
remains, and flowering plants do not appear in the fossil record until
after winged insects and reptiles.
2. Even common present-day floods trap all manner of people and animals.
The violence of a flood that could cover the entire earth in forty days
would be bound to trap many individuals from even fast-moving species,
especially those that were old and infirm, crippled, or trapped in
low-lying areas. Therefore, we would expect to find the occasional
member of fast-moving species near the bottom of the fossil record.
However, the vast majority of fossilized species are only found within
certain relatively narrow ranges within the fossil record. For
example, human fossils are only found at the very top of the fossil
record (Pleistocene period and later), and tyrannosaurs are only found
at the end of the Cretaceous period.
3. The fossil record preserves entire ecosystems, not just individual
species. Fossils of one species are found in association with fossils
of other species common to their ecosystem. If fossil distribution is
dependent on the ability to escape rising floodwaters, then all the
species within an ecosystem must be equally capable of escape for them
to be preserved together. But since these associated species include
both highly motile animals and completely nonmotile plants, this is
obviously not the case.
Sorting by a Combination of Zonation, Hydrology, and Fleeing
Claim 4: The order of fossils deposited by Noah's Flood can be explained by a
combination of hydrologic sorting, differential escape, and ecological
zonation. / Source: Morris, Henry M., 1974. Scientific Creationism, Green Forest, AR: Master
Books, pp. 118-120.
Response:
1. Even this combination of forces fails to explain many aspects of the
sorting of fossils. In particular, the problems with ecological zonation are not significantly
mitigated by the
other two sorting methods.
2. Conventional geology explains the geological record, including its
fossils, mineral content, geomagnetism, and radioisotopes. It does so
in great detail and with great consistency in many, many places. Flood
geology does not give a detailed explanation anywhere; what little
explanation it offers is extremely vague hand waving, inconsistent with
observations.
3. The geological record contains more than biological fossils. Sediment
patterns also record planetary rhythms from which we can determine the
length of the day and long-term changes in climate. From these, we
find that the geological record shows that the moon is slowing consistent with tidal friction (see also Sonett et al. 1996) and
climate changes often follow the Milankovitch cycles (Krumenaker 1995).
These "fossils" depend only on astronomical forces; they could not be
explained by the Flood.
4. There are innumerable other observations that contradict a global
flood (Isaak 1998).

• Microfossil Stratigraphy
Presents Problems for the Flood
by Glenn R. Morton (2000) – below are excerpts from his whole page.
In young-earth models of the global flood, they explain the fossil record as being due to hydrodynamic sorting and ecological zonation. Henry Morris writes: "The hydrodynamic sorting action of moving water is quite efficient, so that each stratum would tend to contain an assemblage of fossils of similar shapes and sizes." (Morris, 1967, p. 40)
If the prediction from the global flood is that small creatures should all be sorted out at the same time, the the fossil record does not satisfy that prediction.
Foraminifera are small, single cellular animals which would have existed in the oceans prior to the flood and due to their small size should be found all mixed together in the same or closely related strata. Foraminifera are used in the oil industry to determine where we are in the stratigraphic section while we are drilling a well. They range from .1 millimeters up to 10 millimeters or more. ...[part of paragraph was cut]...
Given the small size of the average species, they should all sort out at about the same time from the waters of the flood with the largest at the bottom and the smallest at the top. This is not what we find when we look at the foraminifera fossil record. Genera of forams, all possessing the similar shape and similar size and only differing in the details of the test decoration, are found over vast vertical distances in the geologic column. We also find an almost invariant order of these tiny animals in the sedimentary column. In the Gulf of Mexico when we drill sediments that are not near salt the order is invariant. (Salt moves through the sediments of the Gulf of Mexico churning up the sediments near it)
.....< most of his page has been cut >.....
Conclusion
Even if a young-earth creationist dismisses the radiometric dating processes [described in part of the page that was cut], one can not escape the conclusion that the foraminifera rained down on the ocean bottom in a particular order all over the world. This means that there must have been a common cause for this foraminifer rain. Evolutionists simply say that the forams evolved, floated around the world in the ocean waters and when they died, fell to the sea floor. The order is caused by the time when a given species either goes extinct or evolved.
It is very difficult to see how each species of foram could have been on the earth and avoided burial while their fellow forams, which differed very little in size or shape, were all buried together at one time at one level. How in the world a turbulent, global flood could sort these tiny creatures by species is beyond me. As Morris predicted, the global flood should sort things out by size, yet we don't see things sorted by size in the geologic column. If Morris' prediction is correct we should expect almost all foraminifers to have been deposited nearly last and to be only in the uppermost sediments of the geologic column. They aren't. What Morris and other young-earth creationists require is for the global flood to sort these animals by minor visual clues. It is like throwing similar size and density sand particles, which are colored different colors, into a river and having the colors all sort out. This is impossible. Yet forams are so sorted. The only conclusion can be that their order is not due to a global flood but to a long period of deposition in which the animal life changed. The rain of dead forams from a sea with life forms that change over time explains the observed order quite well.
Thus the creationists are wrong on three points.
1. The sorting of the forams and other microfossils show that the deposition of the geologic column was NOT turbulent and catastrophic as they claim.
2. The pattern of species found in the geologic column merely by digging down through the rock layers does not match the survival expectations one would find in which a preflood biosphere was inundated with species dying off with time as the flood progressed. Indeed the absence of oceanic floaters until rocks halfway through the supposed flood period argues strongly against the flood view
3. Gradualistic evolution is documented among these tiny creatures laying bare the false claim that there are no transitional forms. What it shows is that the flood-advocates don't read anything except their own literature.
Glenn Morton also describes similar Patterns in Pollen that would not occur in a global flood in which "the pollen found in with the rocks would mostly have been given off by plants before the flood and we should expect a thorough mixing of the pollen with no clear starting and ending points in the geologic column. [but starting and ending points are observed] All pollen should be found at all levels [but it isn't] because according to the YEC model, all plants were on earth prior to the flood and were doing their thing, releasing pollen and spores into the wind. And then the flood would stir it all up. After all, the flood was a turbulent and chaotic event, eroding miles of pre-flood rock and depositing miles of new sedimentary rocks."
ISOTOPE PATTERNS in the Geological Record
• Isotopic Sorting and the Noah's Flood Model
page (2002) is from the EarthHistory website, with bold (but not italics) in original page.
Stable isotope stratigraphy is a method of correlating
sedimentary deposits in time and space based upon ratios of various stable
isotopes. This
is possible
because the isotopic composition of global seawater evolves
over time, as a
result of various biological and geological processes. Variations
in the isotopic composition
of seawater over time are recorded by various proxies — for instance low-MG
calcite, or inorganic minerals such as barite. Boggs (1987, p. 688) writes: "Variations
in the relative abundance of certain stable, nonradioactive isotopes in
marine sediments and fossils can be used as a tool for chronostratigraphic
correlations of marine sediments. Geochemical evidence shows that the
isotopic composition of oxygen, carbon and sulpher in the ocean has undergone
large
fluctuations, or excursions, in the geological past — fluctuations that have
been recorded
in marine sediments. Because the mixing time in the oceans is about 1000
years or less, marine isotopic excursions are considered
to be essentially isochronous
throughout the world. Variations in isotopic compositions of sediments or
fossils allow geochemists to construct isotopic composition curves that can
be used as
stratigraphic markers for correlation purposes."
The interesting point is that global isotopic changes occur throughout the geologic
record, both in the shells of individual organisms and in inorganic marine
precipitates, such as barite. Isotopic curves have been reconstructed
for the entire Phanerozoic,
documenting changes in seawater isotopic ratios during the past 500+ million
years (e.g. Veizier et al., 1999; McArthur et al., 2001).
Fairly abrupt isotopic
changes can often be correlated across the entire earth, for example a large
del 13C excursion at the base of a specific conodont
zone
correlated with an extinction event. This implies that deposition
of the shells and sediments in the geologic record occured at a rate that
is fairly
slow compared
to the rate at which oceanic mixing occurs, about ≈10^3 years or so (Holser,
Magaritz, and Wright 1986; Kump 1991). This is
inconsistent with models in which a substantial
portion of the geologic record is deposited by a single catastrophe lasting
only months. On the [flood geology] diluvial model, all of the shelly fossils in the geologic
record
are the remains of animals that lived in a preflood ocean prior to the flood. In order to reconcile this hypothesis with the global
isotopic patterns seen in the geologic record, the flood would have to transport
and sort brachiopod
shells, conodonts, forams and other calcerous fossils, and even inorganic
minerals such as barite, by very subtle but consistent differences in C,
O, S, and Sr
isotopic ratios! And it would have to work virtually in real time across
the entire earth. The difficulties entailed by trying to fit these data
into a flood-model
are obvious.
... [most of the page is cut, but I'll include one excerpt]... Erwin (1993) notes that "the isotopic signatures are so similar from sections ranging from restricted basins to open marine that the only reasonable conclusion is that the major shifts are globally synchronous events" (p. 198).
Conclusion
A simple explanation for these isotopic variations and their
concordance from basin to basin is simply that the isotopic composition of
the oceans and
atmosphere have varied over time, and that the isotopic composition of shells,
organic matter and so on in the geologic record reflect the isotopic composition
which prevailed in their environment at the time they lived.
Flood geology,
on the other hand, will hardly be able to explain this data in terms of a
single catastrophe lasting only months. For instance, why would
these variations even exist in the first place, if all the marine organisms
in the fossil record lived immediately prior to the flood? And even
if all these marine organisms did NOT live immediately prior to the flood,
instead
accumulating in the 1600 or so years before the flood, there would still
remain the immense problem of how the flood could possibly
sort forams, brachiopod shells, conodonts, as well as ‘organic matter,’ by
*tiny* but consistent differences
in O, C, S, and Sr isotopic composition, in virtually identical stratigraphic
sequences, in basins separated by thousands of miles.
• Dinosaur Eggs & Nests, and the Flood Theory
According to the "Noah's flood theory" promoted by Answers in Genesis, virtually the entire sedimentary record originated as the result of a single, months-long catastropic flood. Though the text of Genesis states that the flood itself lasted approximately one year, but that by the end of the 40 days of rain, all the mountains were covered with water and "every living thing that moved on the earth perished--birds, livestock, wild animals, all the creatures that swarm over the earth" (7:17). This leads to the expectation that trackways and burrows, if they occur at all, should occur only in the lowest flood deposits. Contrary to this expectation, evidence of living, breathing terrestrial animals are found in strata from the Ordovician onward in the form of burrows (Retallack, 2001) and from the Devonian onward in the case of trackways (Lockley and Hunt, 1995). This directly contradicts the predictions of "flood geology." We would not expect dinosaurs or other terrestrial animals to be walking around underwater at the sediment-water interface, throughout the flood.
Dinosaur nests are another problem for the Noah's Flood" hypothesis. Obviously it is absurd to suppose that dinos swam beneath the flood waters to construct nests and deposit their eggs, often in carefully arranged patterns. [Eggs are found arranged in various patterns within the nest, including circular and spiral arrangments, erect and flat-lying. Individual clutches with up to 26 eggs are known. Some "nesting sites" are huge and laterally extensive.]

The page-excerpts below (with links to the full pages which include pictures) are all by Glenn Morton:
• While the Flood Rages, Termites Dig, Dinosaurs Dance and Cicadas Sing
No, this isn't about termites eating the ark, although that is quite a problem. I do know where the termites were during the flood. They were busy eating and being eaten by predators. They were living their lives as if a global flood wasn't happening. Amazing, I know.
... [middle part of page is cut, between the first and last paragraphs, above and below] ...
Features like these - termite nests, dinosaur tracks, cicada burrows and channels - are not easily explainable by the YECs. They don't show their followers this type of data, and they have not explained it. Such photos do not make it into the YEC literature, which shows the intellectual dishonesty of the YEC leaders. Honesty demands that data like this be shown and explained. But sadly it isn't.
• Tracks and Raindrop, Hail and Ice Impressions Demonstrates Slow Deposition
One of the fascinating aspects of the geologic and paleontologic record involves the capturing in stone of slow processes which are incompatible with the young-earth creationist idea of a global flood.
... [middle part of the page has been cut] ...
The features discussed above clearly don't require a global flood to form. Indeed, quite the opposite, they indicate a slow rate of deposition.
• Three Hundred Years in the Middle of the Flood -- Evidence of Time in the Geologic Record
One of the things that young-earth creationists miss is the activities of biological organisms in the fossil record. Desert varnish is an iron manganese oxide coating that is found on rocks in arid regions. For years this coating was thought to be an abiologic chemical reaction. This has been shown to be false. Desert varnish is now known to be the result of bacteria which live on the surface of the rocks and through their biologic activity deposit a manganese rich coating on the rock surface. Living in nearly a waterless environment, these microbes protect themselves from ultraviolet light by oxidizing the manganese in the rock. (Wills and Bada 2000, p. 165-166)
When European priests first entered the arid southwestern US, they found vast tracks of land with cobbles dark on the top and light on the undersides. They turned the stones over making huge, light-colored crosses in the desert. In the intervening 300 years, the crosses are still visible but are now beginning to fade. It has taken 300 years for the microbes to cover the stones' upper surfaces with varnish.
With this as a background, what is one to conclude when we find this same type of varnish coating Permian sand grains in the Zechstein of the North Sea? The Permian rocks are from the very middle of the supposedly flood deposited rocks. This should be the time of the maximal flooding of the earth, yet here we find desert varnish which requires at least 300 years to form. Not only this, the sand grains which are coated with this slow-forming film, are found in shape of sand dunes like those found in arid regions today. (Ruffell and Shelton, p. 305)
Clearly this evidence shows that there was at least a 300 year interval in the middle of the flood. This is something that the young-earth creationists never tell you! [this is the entire text of the page, with no cuts]
• Salt, Meteors and the Global Flood
Global Flood advocates put most of their efforts with regard to salt to explain how the oceans supposedly couldn’t be as old and evolutionists say. But they never tell their readers about the evidence within the salt which proves huge ages and slow deposition of the salt.
The very presence of bedded salt in the geologic record is evidence that it was not deposited during a WET global flood. Salt dissolves in water, it doesn’t deposit out of water unless the water is saturated with salt. And when it is saturated with salt, no vertebrate life can live in those waters. So, why do we find huge salt beds in the middle of the geologic column and which are very widespread? All of Michigan is underlain by the Salina Salt which reaches as much as 3100 feet thick. How did this happen in the midst of the biggest water event in history—the Noachian flood?
Some creationists have claimed that a mechanism by Omer B. Raup will explain the salt. In this mechanism, brines of different mixture come in contact with each other and when the interface is stirred, salt is deposited. That is the only known method of salt being deposited under water. But will it explain the salt we see in the geologic column? No.
If the salt were deposited by Raup’s mechanism in a global flood with its turbulence, the salt should contain much mud quarts and other impurities. But salt is relatively pure. The biggest contaminants are other evaporative minerals like gypsum, anhydrite and carbonate. Salt beds contain almost no clastics.
But one other contaminant they have are microscopic plankton. The existence of such creatures makes it appear as if the salt really were evaporated! They also contain pollen grains, which are known to fall out of the air. This contamination makes it look as if the salt were open to the air at the time it was deposited. This is something that is incompatible with the global flood concept.
... [part of page was cut] ...
Another deposit contains meteoritic dust in quantities consistent with what would be expected from a slowly evaporating basin. ... [more cuts]
Why would a global flood, which all agree was a very watery event, deposit salt in such a fashion as to make it look like it was really evaporating. The salt beds lack the features we would expect in a global flood—large quantities of the erosive quartz and shale generated by all the erosion going on in the flood---but they contain the features—pollen and meteoritic dust-- at just the quantities expected from slow deposition. Did the flood meteoritic dust influx speed up just exactly as much as is needed to make the salt LOOK like it was deposited slowly? Why would God do that? I bet no global flood advocate here can tell us how the flood did this. [end of page is cut]

• Counting Rock Layers
by Don Lindsay
Regardless of how they formed, it would seem odd to have a rock of
more than 6,000 layers in a world that is 6,000 years old. So, without
using radioactive dating or astronomical dating we could try simply
counting layers.
For instance, we could count the Green River formation in
Wyoming. It contains more than 4,000,000 layers, or varves,
identical to those being laid down today in certain freshwater lakes.
The sediments are so fine that each layer would have required over a
month to settle.
The basic reason for varves is that rivers run faster in the
spring. A flooding river is able to carry coarse material. During the
rest of the year, the river is slower, and it can only carry
less-coarse material. The result is that lake bottom deposits tend to
alternate, coarse/fine/coarse/fine.
Studies of present-day lakes don't always show two layers per year.
There might be a cycle of 2, 3 or 4 distinct sediments, and then the
same cycle repeats. But in the Green River varves, the cycle has only
two layers - a fine light sediment, and an even finer dark sediment.
And of course the occasional storm might add an extra
layer. However, this hardly turns millions of layers into a 6,000 year
project.
• Varves: Layered Sediments as Evidence for an Old Earth
by Perry G. Phillips
A varve is a pair of thin layers of sediment. Typically, one band of the varve is light and
composed of sand, pollen, and spores, while the second layer is dark and composed of very fine
clay particles.
Varves are formed by seasonal variations in sedimentary deposition. The lighter band is laid
down during the summer when a greater flow of water in nearby rivers and streams brings coarse,
sandy material into the lake. The larger particles settle rather quickly, but the winds that
constantly agitate the surface of the lake keep the fine clay in suspension. In winter, when the
lake freezes over, the effect of the winds is not felt, and the clay particles slowly settle to the
bottom. When the lake thaws, the cycle begins anew. Each varve, therefore, typically represents
one year. One can determine the age of a varve formation by counting the number of couplets,
just as one can determine the age of a tree by counting its rings.
Varve deposits display great age. The Salido, Castile, and Bell Canyon formations of west
Texas contain 260,000 couplets. Hence, this formation is most naturally considered to be
260,000 years old. Core samples have also revealed that these varves have uniform thickness
over many square miles.
Young Earth Creationists, of course, reject such an old age for this formation. They attribute
its origin to Noah's Flood, which lasted about one year. To lay down 260,000 varves in one year,
however, requires that about 720 couplets be laid down each day, or about one pair every two
minutes - an implausible scenario given the evenness, extent, and alternating composition of the
layers.
Young Earth Creationists are even more hard-pressed to explain the origin of the Green River
Shales. These varves span parts of Colorado, Utah, and Wyoming, and cover 40,000 square miles
with about 7.5 million paper-thin couplets. This formation is 2500 feet thick, and it lies upon
another 25,000 feet of sedimentary rocks. Flood geologists attribute the entire 27,500 foot
configuration to the work of Noah's Flood. This means that about 75 feet of sediments were
deposited every day. For the shales, 75 feet amount to 225,000 couplets. This corresponds to
2.5 couplets formed each second, for one year, with the correct light-dark alternation of the
bands, over an area of 40,000 square miles - an unbelievable feat.
Further difficulties with explaining all this sediment as laid down by the Flood arise from
fossilized evidence of birds, such as nesting sites, egg shells, coprolites (fossilized feces), and foot
prints - all in a layer just below the shales. These remains match present-day flamingo nesting
sites in East Africa, so it is reasonable to attribute the fossilized sites to flamingos that lived by the
lake in which the Green River Shales formed. It is hard, however, to see how flamingos could
hatch their eggs, raise families, digest the food from which the coprolites were formed, and take
walks with 75 feet of sediment piling on them every day!
Young Earth Creationists point out that fossilized fish that span hundreds of couplets are found
in the shales. They argue that dead fish could not have lasted hundreds of years without
disintegrating; hence, the varves do not indicate seasonal depositions. Chemical analysis of these
sediments, however, reveals that the water of the lake in which the varves formed was very
alkaline. The dead fish, in effect, were pickled; they would not decompose and would have lasted
for such duration as it took to cover them with sediments.
In light of the positive evidence for the great age of these varves, combined with totally
unacceptable explanations for their formation by Noah's Flood, it is clear that they are much older
than the 10-20,000 years claimed by Young Earth Creationists as the age of the earth.
• Varve Details
by Glenn Morton (below are
excerpts from a page about Young-Earth Arguments)
This [photos are omitted in these excerpts] is Figure 4 in Lambert and Hsu's article. Lake Walensee
Storm Varves (Left) vs. Lake Zurich Yearly Varves (Right). [they look very different] Notice the regular
laminations on the part of the yearly varves.
Steve Austin wrote: "Thin, rhythmic silt and clay layers found
in lakes are frequently called 'varves,' with each layer being considered
to represent annual repetitions of a slow sedimentary process. Lambert
and Hsu present evidence from a Swiss lake that these varve-like layers
form rapidly by catastrophic, turbid water underflows. At one location
five 'varves' formed during a single year." (Austin 1984, p. 272)
Obviously, Austin did not read the article carefully enough. The above
is a drawing of Figure 4 in Lambert and Hsu's article. Lambert and Hsu
stated "We do not intend to make an unwarranted generalization that
no varves are deposits of annual cycles. Figure 4 shows varves from the
mesotrophic Lake Zurich where the light laminae represent chemical sedimentation
prevailing during summers and the darker laminae detrital sedimentation
during winters. A comparison of those varves with the non-annual varves
of the oligotrophic Walensee shows that the annual rhythms of Lake Zurich
varves are more regular, while the irregularity of the Walensee 'varves'
reflects the unpredictability of the weather."(Lambert and Hsu, 1979,
p. 453-461) Austin's representation of Lake Walensee's varves as indicative
that nonyearly varves are identical to yearly varves is entirely erroneous.
Pollen in the Varves:
Regular varves like those shown above on the right were described by
Richard Foster Flint, an expert on Quaternary geology. He said (1971, p.
400),
"A rhythmite deposited in a lake near Interlaken in Switzerland
consists of thin couplets each containing a light-colored layer rich in
calcium carbonate and a dark layer rich in organic matter. Proof that the
couplets are annual, and therefore varves, is established on organic evidence,
first recognized by Heer(1865). The sediment contains pollen grains, whose
number per unit volume of sediment varies cyclically being greatest in
the upper parts of the dark layers. The pollen grains of various genera
are stratified systematically according to the season of blooming. Finally,
diatoms are twice as abundant in the light-colored layers as in the dark.
From this evidence it is concluded that the light layers represent summer
seasons and the dark ones fall, winter and spring. Counts of the layers
indicate a record that is valid through at least the last 7,000 years B.
P. "
A cursory look at the layers in the figure above shows that they are
not the same thing.
Carbon 14 and Varves:
Lake varves contain much organic material which can be dated by carbon
14. If the varves are yearly and the radiocarbon dating method works, then
the radiocarbon dates should be just about equal to the varve count. Below
[diagram omitted here] are the results of a study done by Alan Craig. He counted 10,200 varves
and then radioactively dated the organic material in the core. Notice that
the C-14 ages agree very well with the varve count. (Turekian, 1971, p.
61)
The main young-earth responses (as summarized by John Morris and Kurt Howard, which you can find in the links-page for age-science) are discussed below.
• Rebuttals of Creationist Claims
edited by Mark Isaak for Talk Origins — The whole page includes links & references.
Claim CD241: Varves (layers of silt that show seasonal differences) do not necessarily
form annually. Individual varves can form in less than a year. Thus,
claims that 10,000 varve layers represent 10,000 years are unwarranted.
Source: Garner, Paul, 1997. Green River blues. Creation 19(3) (June-Aug.):
18-19.
Response:
1. The seasonal nature of varves is sometimes indicated by the systematic
variation of pollen from seasonal plants (Morton 2002; citing Flint
1971, 400).
2. There is at least one formation that contains twenty million varves.
That represents more than 50,000 years even if you assume varves were
formed at a rate of one per day. And the fineness of the silt
precludes the possibility that they could have formed that rapidly.
3. The 45,000-year varve record of Lake Suigetsu is consistent with
other dating techniques, such as carbon-14 dating and the tree ring
record (Kitagawa and van der Plicht 1998).
4. Non-annual fine-grained layers are recognizably different from varves.
Layers that form rapidly tend to be much more irregular, reflecting
the changes in the weather conditions that cause them (Morton 1998).
Annual varves are observed forming today. They produce uniform layers
seen also in the geologic record.
• Exploding Fish: Evidence for Rapid Burial — by John Whitmore (young earth)
The Green River Formation (GRF) of Wyoming (left) contains millions of exquisite fossil fish that are sought by collectors worldwide (Figure 2). Because so many beautiful specimens have been harvested from the GRF, few realize that many of the fish remains are far from perfect. In fact, many of the fish are disarticulated, their bony remains and scales scattered, no longer connected together as when they were alive (Figure 3). Studying fossils and the layers of rocks they are contained within can give us clues as to whether the fossils were formed during or shortly after the worldwide cataclysm popularly known as Noah’s Flood. ...[3 sections in the page are omitted]...
Rapid Burial: Experiments and observations of dead fish in modern settings show that they decay within days or weeks after death. Perfectly preserved fossil fish that do not show any signs of decay must have been buried rapidly. Modern lakes normally do not contain fish remains because mud is not accumulating quickly enough within them to preserve the remains. Some fish in the fossil record do show signs of decay, but even those fish must have been buried soon after the decay began. In other words, rapid burial must have occurred in order to preserve their exploded remains in the fossil record. / Scientists have studied decay in fish, as well as many other groups of organisms. These experiments overwhelmingly show that rapid decay takes place in many types of organisms under many conditions.
Summary: Rocks which contain fossils show that the rocks must have hardened quickly in order to preserve their fossil remains. When sedimentary rocks are examined, many of them contain exquisitely preserved fossils. Fish fossils and all other types of fossils demonstrate that rocks have accumulated quickly in the past and not over millions of years, as conventional geology teaches.
• Fossil Fish — by Brad Henke, from his Response to Jonathan Sarfati below
The
Green River Formation contains some beautifully preserved fish and other fossils. However, except for microfossils, fossil-bearing laminae are uncommon in the formation
(Fischer and Roberts, 1991, p. 1147). J. Sarfati and other YECs are skeptical that
dead fish could have laid undisturbed on the bottom of lakes where they were slowly
encapsulated into varves over many years. YECs insist that the fish and other
well-preserved fossils had to have been buried quickly by "Noah's Flood" or
subsequent "post-Flood" catastrophe(s). Otherwise, they claim, the fossils
would have been destroyed by decay and scavengers.
Drever
(1997, p. 166-169) states that the bottoms of deep water (eutrophic) lakes may become very
anaerobic if the cold bottom waters (the hypolimnion) remain dense and stagnant.
That is, the bottom waters of lakes may not experience frequent seasonal mixing and
aeration, especially in depositional environments like those of the Green River Formation,
where the bottom waters were probably saltier and, therefore more dense, than the surface
waters (Drever, 1997, p. 169; Fisher and Roberts, 1991, p. 1147). Currently, these
eutrophic conditions are also present in the Black Sea (North, 1990, p. 44).
Fischer
and Roberts (1991, p. 1147) and Strahler (1987, p. 233) further discuss in more detail the
field and geochemical evidence on why scavengers were often absent in the Green River
Formation. Not only was the deep and quiet water too stagnant (low oxygen) and salty
to support scavengers and aerobic decay-promoting bacteria, but the water probably had too
much highly poisonous H2S to support scavengers, burrowing organisms, and most bacteria
that would have destroyed organic remains and disrupted varve structures. Strong currents
would also not have been expected in the stagnant water, so the fish corpses could have
remained intact and undisturbed for many years until burial. Nevertheless, Ripepe et al.
(1991, p. 1157) show photographs of varves that have undergone possible small-scale
bioturbation, so varve disruption and decay may have occurred at some of the sites.
• Ideas about Layers
by Jonathan Sarfati (young-earth, in a rebuttal of Mark Isaak's Problems
with a Global Flood)
Isaak [question]: “How can a single flood be responsible for such extensively detailed layering?”
Answer [by Sarfati]: Isaak is evidently ignorant of the Mt. St. Helens volcano and sedimentation evidence of Berthault, et al., published in the Creation Ex Nihilo Technical Journal. These show that the layers do not need to form slowly, one at a time, but can form simultaneously by a self-sorting mechanism as the differently-sized particles roll over each other. A recent Nature article on spontaneous multi-layer formation shows that the secular journals have finally caught up with the creationary scientists, who published evidence like this 10 years ago so much for the bigoted evolutionists’ claim that “creationists do no scientific research.” See the CENTJ article, Sedimentation experiments: Nature finally catches up”. Isaak also seems unaware that Mt. St. Helens laid down 7.6 metres (25 feet) of finely laminated sediments in a few hour. More recently, Iceland’s recent “mega-flood” (jökulhlaup) also laid down many finely laminated rhythmites.
Isaak [question]: “How do you explain the formation of varves? The Green River formation in Wyoming contains 20,000,000 annual layers, or varves, identical to those being laid down today in certain lakes. The sediments are so fine that each layer would have required over a month to settle.”
Answer [by Sarfati]: The self-sorting mechanism described above explains that. It’s simply nonsense that the layers would have to form slowly, and/or one at a time. The evaporite mechanism fails to explain the variation in the number of layers between the same pair of volcanic ash layers. More importantly, it fails to explain why there are fish and other fossils many different layers. They would have decayed if they were on the bottom for thousands of years being slowly buried layer by layer (the varves are 0.1 mm thick in one of the fossil-bearing sections). This applies even if the water was low in oxygen.
• Ideas about Layers
by Brad Henke (in a response to Sarfati's rebuttal)
Origins of Layered Sediments, including Varves
Laminae
are very thin, parallel layers of sediment or sedimentary rock. By definition, laminae are
less than one centimeter (cm) thick (Blatt et al., 1980, p. 129). Sometimes,
hundreds of thousands or millions of laminae may be stacked on top of each other.
The lateral length of laminae varies greatly and, in some cases, individual lamina
have been laterally traced for at least 90 kilometers (55 miles) (Blatt et al., 1980, p.
553)!!
J.
Sarfati and YEC Snelling ... loudly proclaim
that YEC Austin has made an important discovery at Mt. St. Helens; that is, laminar- and
cross-beds can rapidly form.
Before J.
Sarfati and other YECs further proclaim Austin's "discovery" of rapidly
developing laminae and cross-bedding, they should look at the literature and learn some
geology. For decades, geologists have known that cross-bedding and laminae can form
in rapidly deposited pyroclastics (especially, surges).
Clearly,
Austin's work at Mt. St. Helens is nothing unique or revolutionary. It's just
another pyroclastic deposit with ordinary laminar- and cross-beds.
Green River Formation
Some, but
not all, laminae are varves. Varves are couplets of laminae that result from
seasonal changes. Typically, varves consist of alternating light- and dark-colored layers
(Blatt et al., 1980, p. 133). In temperate lakes, for example, the light
layers may form from sediment runoff during the summers, while the dark layers may
represent organic matter that settled during the winters. Frequently, each couplet
represents an annual accumulation of sediment. Therefore, by counting couplets, the
age or length of the accumulation time may be estimated for a series of
varves. In a way, varves resemble tree-rings.
The
famous Green River Formation of Wyoming contains numerous laminae, some of which are
varves. The formation and its varves probably developed in several large Eocene
lakes. The Green River Formation is frequently cited by YEC critics because the
numerous varves refute both "Flood geology" and a "young" creationist
Earth. J. Sarfati and other YECs argue that the rocks of the Grand Canyon and the
Green River Formation and its varves may have formed rapidly, just like Austin's
pyroclastic "flow" at Mt. St. Helens. However, clearly, it is a gross
mistake for J. Sarfati and his YEC allies to assume that the rapid processes that formed a
pyroclastic deposit at Mt. St. Helens can be scaled up to explain the geology of the Grand
Canyon or the delicate and extensive varves of the Green River Formation. For
example, as far as I know, the laminae of the Green River Formation do not include
cross-bedding, antidunes or other features that are present in Bouma sequences and many
pyroclastic deposits.
Now,
there is no doubt that multiple laminae MAY form in a single season or even from a single
storm or sediment flow as Austin (1994, p. 37-39) and other YECs claim. However,
YECs are mistaken if they believe that ALL laminae form rapidly. [some of page was cut]
Now,
scientists KNOW that NOT all of the layering in the Green River Formation are varves. [some of page was cut]
Some
individual varves in the Green River Formation may extend for ten's of kilometers (Fischer
and Roberts, l99l, p. 1148) and there are more than 5,000,000 individual couplets or a
total of more than 10,000,000 individual layers (Strahler, 1987, p. 233). J.
Sarfati quotes Berthault (1988b, 1990) and invokes a "self-sorting mechanism" to
explain the rapid formation of numerous laminae at once in the Green River
Formation. So, if this "sorting mechanism" was responsible for the laminae
in the Green River Formation, how could this mechanism instantly produce numerous
fine-grained laminae over ten's of kilometers (Fischer and Roberts, 1991, p. 1148)?
It's one thing to rapidly produce some laminae in a laboratory separatory funnel (see
Figure 1 in Sedimentation
Experiment: Nature Finally Catches Up!, it's another thing to rapidly deposit
thin layers of very fine-grained clay and silt over ten's of kilometers. That is,
unlike relatively coarse sand particles, very small particles (silts and clays) take TIME
to settle out of solution. So, how could Berthault's "self-sorting mechanism"
speed up the deposition of silts and clays? ...[some of paragraph was cut]... YECs must also explain how 10,000,000
layers, some of which may extend over tens of kilometers, can catastrophically form
without eroding previously deposited layers or producing cross-bedding and other
non-linear features. Simply hoping that Berthault's laboratory work could somehow be
scaled up to ten's of kilometers isn't good enough.
Worst of
all for young-Earth creationism, variations in varve thickness within the Green River
Formation clearly fall into regular cycles, several of which correlate beautifully with
various LONG-TERM climatic and astronomical cycles (Fischer and Roberts, 1991; Ripepe et
al. 1991):

Notice
that the cause(s) of some of the cycles have not been explained. Other expected cycles
were not detected in the research discussed in Fischer and Roberts (1991) and Ripepe et
al. (1991). The cycles are real; there's no conspiracy here. Petrographic, statistical and
geophysical methods have detected the cycles and some of them have been seen over and over
and over again in the Green River Formation for the past 70 years.
Notice
that YEC web sites, like this one: Varves:
Problems for Standard Chronology or the one recommended by J. Sarfati: Green River Blues,
completely IGNORE the associations between varve thickness and astronomical and climatic
cycles. Why? Because these correlations utterly refute young-Earth creationism and YECs
haven't been able to cook up any natural explanations to deal with them. Why would laminae
segregate by cycles to conform to the Earth's eccentricity if the Earth is too young to
have completed even one of these cycles? How did Noah's "Flood" or
"post-Flood" conditions counterfeit the effects of ENSO and the sunspot cycles
in these varves? No rivers, turbidity currents, or any questionable speculations
based on Berthault's laboratory results can explain them either. YEC claims (they're too
inadequate to be called models) for the origin of the Green River Formation are too fast
and chaotic to be affected by subtle astronomical and climate cycles. Quiet and stagnant
water is needed to record these astronomical processes and slow climatic changes. All YECs
can do is invoke groundless miracles or ignore 70 years of research and just refuse to
acknowledge the existence of the cycles.
FOSSIL PATTERNS in the Geological Record — Part 2
This section shows two young-earth responses to old-earth claims about fossil patterns.
• Fossil Patterns: A Classification and Evaluation
by Jim Gibson - young earth - Geoscience Research Institute, paper is from Origins 23(2):68-99 (1996).
Summary
One of the most interesting challenges in understanding
Earth history is explanation of the order in the fossil record. Identification and
analysis of fossil patterns may provide one of the tools needed to reach a better
understanding of the fossil record. Fossil patterns and fossil trends that extend through
the fossil record imply that some processes acted throughout the production of that
record. In this paper, 25 reported fossil patterns are classified into four categories:
fossil diversity patterns; fossil morphological patterns; fossil ecological patterns; and
depositional patterns. Possible creationist and evolutionary interpretations of these
fossil patterns and trends are described. Some fossil patterns seem difficult to explain
from a creationist viewpoint; others seem difficult to explain from an evolutionary
viewpoint. Further research of fossil patterns and fossil trends may aid in our
understanding of the processes that were responsible for producing the order in the fossil
record.
Study of the fossil record has revealed much about the past. Our
knowledge has been developed through the study of such features as anatomical structures,
the degree of preservation, the types of fossils found together, and the nature of the
surrounding sediments. With the accumulation of such data, it is natural that comparative
studies would be undertaken to determine what patterns can be identified. Patterns in the
fossil record may provide valuable clues to identifying processes active during production
of the fossil record. This paper is intended to survey and classify the types of fossil
patterns that have been reported in the literature, and to comment on their possible
significance.
... [most of paper has been omitted] ...
Discussion
Those who have hoped fossil patterns and trends would reveal a
straightforward story of Earth history have met disappointment. Some features of the
fossil record seem to suggest one view, while other features seem to suggest another.
Persons with differing views of Earth history can point to selected features of the fossil
record to support their views.
Regardless of the viewpoint, our understanding is incomplete. The
challenge to creationists is to explain fossil trends as the result of the way in which
the Flood eroded and buried the biota of various habitats. The creationist viewpoint
considers ecological and depositional trends to be primary. Diversity trends and
morphological series are considered to be secondary consequences of the primary trends.
From this viewpoint, ecological fossil trends are interpreted to
reflect the expansion of Flood activity as additional habitats and additional geographic
regions were swept away. This implies segregation of habitats in a highly structured
pre-Flood ecology. The observed ecological fossil trends are trends by addition, not by
replacement (see Appendix 3). Since relatively dense and immobile marine
invertebrates are found in upper layers as well as in lower layers, there must have been
additional source areas available for destruction at different stages in the Flood. This
is why pre-Flood marine habitats are postulated to have occurred in different regions and
at different elevations. This part of the explanation seems ad hoc, but a highly
structured pre-Flood ecology seems to be an essential part of the theory.
Depositional trends are less frequently reported, but a few have been
identified (see Appendix 3). The decrease in relative importance of limestone
together with the increase in lake deposits can be linked to the expansion of the Flood
beyond the main ocean bodies into the terrestrial environment. Habitat inferences based on
depositional energy might alternatively be considered under depositional patterns. More
study in this area is highly desirable. The relative geographic locations and
stratigraphic positions of high energy and low energy deposits might provide helpful
insights into the sequence and extent of various local or regional events during the
Flood. The same could be said of patterns of storm deposits and lagerstätten. It would be
interesting to determine if these patterns could be related to extraterrestrial impacts,
plate arrangements, or paleocurrents. More information is also needed about possible
trends in taphonomic processes.
Several diversity trends can be interpreted as the result of the
expansion of Flood activity (see Appendix 1). Among these are coordinated appearances
(e.g., the Cambrian Explosion), increasing diversity, disparity before diversity, and
coordinated disappearances. The precise and consistent stratigraphic sorting of fossils
into different strata is more problematic. A large-scale sorting mechanism is required to
explain the consistency of the sorting over continent-sized geographic regions. The Flood
may provide such a mechanism, but the details have yet to be worked with. The trend toward
increasing provinciality also seems problematic for the Flood theory.
Morphological patterns provide a mixed bag for creationists. Most
morphological patterns are consistent with creationist expectations (see Appendix 2).
These include morphological stasis in fossil species, morphological gaps among species,
systematic gaps among higher taxa, higher-taxon stasis, coordinated stasis, lack of
ancestors, and ubiquitous morphological specialization. Many body-size trends may be
expected in a flood, but further study is needed to clarify the processes involved.
Increasing complexity may be a secondary effect of increasing terrestriality among
vertebrates. The most significant challenges to creationism from the fossil record are
probably the increasing similarity to modern species and stratigraphic sorting of species
into morphological series. These trends are the most important fossil evidence for the
alternative to the Flood theory, the theory of evolution. One of the major goals of
creation scientists should be to provide alternative explanations for morphological series
of fossils. Some morphological series have been linked to ecological rather than
evolutionary causes, but much more study is needed in this area.
Conclusion
The fossil record is a record of destruction and death. Is it the
record of undirected history, in which every species lives for a while, then becomes
extinct? Does it trace an evolutionary history of common ancestry, natural selection and
improvement? Or is it a record of worldwide catastrophic destruction, designed to serve as
a reminder of the effects of sin? Science alone does not provide a satisfactory answer,
but the Bible indicates the latter interpretation is the correct one. The details are not
given, and no present theory adequately explains all the data. No one has been able to
figure out how to put everything together. However, by comparing the Bible and the fossil
record, we can find meaning in the geologic column. Catastrophic activity and global
patterns, perhaps the two most important predictions of the Flood theory, are clearly seen
in the fossil record. The sudden, abrupt appearance of morphological disparity among
marine animals in the "Cambrian Explosion" speaks of the beginning of the Flood.
The terrible destructive power of the Flood is seen in the many extinct fossil groups. The
lack of ancestors in the Precambrian rocks indicates the separate creation of many
different groups. The presence of morphological gaps among higher taxa throughout the
fossil record further illustrates this point.
Not everyone will interpret the record in this way. But those who are
willing to test their ideas by the Bible can see divine purpose in the fossil record. This
evidence affirms the reality of divine purpose in the present, and in the future.
• Foraminifers in the Fossil Record: Implications for an Ecological Zonation Model
by Tammy Tosk - young earth - paper was in Origins 15(1):8-18 (1988).
Do the sequence and diversity of foraminifers in the fossil record represent
evolutionary development, or are there alternative explanations? The fossils in the geologic column have been thought to be a record,
although certainly not a complete record, of the development of life on Earth. Because the
prevailing paradigm assumes that the current processes operated at current rates in the
past, the fossil record is assumed to have been formed slowly as evolving plants and
animals lived, died and were buried, as we observe today.
Scientists working under that paradigm look for different kinds of
information than do those who assume that the fossil record is the result of a major
catastrophe. Because they think that fossils buried low in the geologic column must be
much older than and ancestral to those buried in the upper parts of the column, they look
for similarities and differences indicating evolutionary relationships.
Many scientists also assume that the fossils lived in the area where
they were buried and fossilized, only being transported before burial in ways similar to
those observed today. Fossils would thus give information about the environment of the
area where they lived and died.
If a major catastrophe such as the Noachian flood was involved, the
fossil distribution would be the result of factors other than just time and evolutionary
change. A scientist looking at the fossil record under a flood paradigm would assume that
most of the fossilized plants and animals had been living contemporaneously, and this
scientist would look for characteristics of the fossils that would explain their order of
burial during a major catastrophe. Some of the information needed for such an
interpretation is often included in the reports generally published, but much is not.
Species descriptions give information about the shape and structure of
the fossil, but may not give differences in size, thickness and weight that would be
significant in studies of their buoyancy and other transport characteristics. Differences
in preservation, which could be indicative of extensive transportation, are generally only
mentioned as problems for their identification. Stratigraphic occurrences (the vertical
range of the fossil in the geologic column) and geographic occurrences (the locations
where the species has been found) are generally given when known. However, only a small
fraction of the sedimentary rock in the crust of the earth has been examined for fossils,
so their true distribution and abundance can only be estimated.
Another problem with using published descriptions and stratigraphic
data is that fossils are often placed in different taxa, even in different superfamilies,
if they are found at different levels, even though they might be placed in the same genus
or species if found together. It is therefore difficult to recognize potentially
equivalent species in the geologic column.
Several questions must, however, be asked of the fossil record to
determine if its formation could have taken place within a short period of time. To show
the plausibility of a model in which a significant part of the geologic column was
deposited during a one-year, world-wide flood and its aftermath, one must show that all
the fossils in flood deposits could have been deposited or reworked during the flood
events into the observed biostratigraphy, and that similar organisms living after the
flood would have a biogeographic distribution and genetic variability consistent with the
loss of most of their population during the flood events.
To fully answer all these questions for all the fossil groups would
require many lifetimes of research. This paper will explore only the group with which I am
most familiar the microfossils called foraminifers.
Significance of Foraminifers
Protozoans of the Order Foraminiferida have been used extensively
for relative dating of marine sedimentary rocks. They are small, generally less than a
millimeter in length, and often found in such abundance that hundreds of specimens can be
recovered from a mudstone sample with only a few hours of work. Because they are easily
recovered from drilling chips, they are used to correlate strata in oil wells. An
extensive literature of taxonomy and stratigraphic occurrences has therefore been
developed for economic as well as academic reasons.
Foraminifers have more architectural diversity than any other fossil
group. Many forms are long-ranging, being found through major segments of the fossil
record. Other more specialized forms have very restricted ranges, and so are useful as
index fossils. Foraminifers can therefore be used to correlate most marine sedimentary
deposits.
... [most of the paper has been cut] ...
Conclusion
The abundance, diversity and distribution of foraminifers in the
fossil record exemplify many of the problems of fitting the fossil record into a short
chronology, such as the multitude of species, large numbers of organisms, and apparent
evolutionary sequences of simple to complex forms. Living species of foraminifers exhibit
diverse morphological forms under varying environmental conditions, raising the
possibility that many of the nominal species in the fossil record are actually
ecophenotypes. In this case, a long time for evolution to take place would not be
required. Presumed evolutionary sequences could then represent populations living in
different environments or in the changing conditions during the flood and as it subsided.
Foraminifers are sparsely represented in the fossil record up through
the Triassic, with most specimens found in small fossiliferous deposits. [?? 12
October 2001] With this in
mind, and the fact that foraminifers can multiply rapidly, it seems plausible that the
number of organisms found in the geologic column could have been produced in the time
since creation.
The distribution of foraminifers in the fossil record seems to bear
some resemblance to their ecological distribution in the oceans today. Fossil benthic
species are found in most Phanerozoic strata, and similar forms are found living in
ecological zones ranging from the deep sea to brackish estuaries. Fossil planktonic
species are found only in Jurassic and younger strata, while living planktonic species are
found floating in the upper parts of the water column. These distributions seem consistent
with an ecological zonation model. The extinct large fusulinids in the Upper Paleozoic are
anomalous, however. They are interpreted to have had symbiotic algae, so must have lived
in shallow environments, perhaps in the upper ecologic zones of a low elevation sea.
