Percipient would be perfectly correct to say it and visit to a natural history museum with a decent fossil collection would confirm out. The deeper the deposition (in general, of course, allowing for disturbances to the stratigraphy) the more unlike modern forms the fossils become. Of course, there are some genera which which fit persistent niches and they can be found in more or less modern form going way back. That is entirely to be expected.
BTW, Percy did not create a circular argument but dates the ages of these forms with radiometric dating. I know you don't trust radiometric dating, but that really is up to you. Percy's argument is perfectly sound, unless radiometric dating is wrong, but that is a different issue on which you have failed to make noticeable progress elsewhere in the forum.[/B][/QUOTE]
