Not only is the fossil record thinner so is the living biosphere. Gish is
wrong on this. There are 3245 living genera of
fish; there are 1837 extinct genera. My sources for this information were
Robert L. Carroll, Vertebrate Paleontology and Evolution, (New York: W. H.
Freeman and Co., 1988), pp596-612 for the paleontological data (plus a few
living genera) and for the living genera
was:http://nypa.uel.ac.uk/fish-bin/fishfam.pl
According to Groliers ENcyclopedia, there are today 20,000 species of fish.
That works out to be about 7 species per genera. Using this there are 7 X
1837=12859 which means we have probably catelogued around 32-33000 species
of fish.
