Trilobites are found above the Cambrian. They are found from the Cambrian
to the Permian and then are found no more. I can also tell you that there
are lots of other animals that are only found in a restricted part of the
geologic column and thus are found in an invariant order whereever they are
found. I love the Ammonite index fossils. Ammonite species are determined
by the shape of the suture that connects successive sections of the Ammonite
shell. The suture can be simple or quite complex. The size ranges of the
various ammonites species are similar so hydrodynamic sorting should not
account for the layering of ammonites by suture shape. Here are the
world-wide layering of ammonites.

Standard Stages and Ammonite zones of the Jurassic of NW Europe.
"From the Hettangian up to the Middle Kimeridgian these stages
can be recognized all over the world, but after that the scheme
breaks down owing to regional differentiation of faunas." IBID p.

WHY should ammonites be layered WORLDWIDE by suture shape????? Evolution is
the only answer where various animals evolved and died out at successive times.
