"...Alan Doty showed me a slab of brachiopod remains on an outcrop near the top of the Canyon. All of the fossils were of the same creature. Some time later, Dr. John McDowell showed me a similar slab of brachiopods near the bottom of the canyon. These two slabs of brachiopods were relatively the same size, but the brachiopods were radically different and wear different names. They are as different from one another as a Chihuahua and a St. Bernard. .... Floods do not put one kind of animal in one layer and a different kind of animal with the same size, mass, and density in another. Floods make a huge twisted mess of everything. This is one of the many problems with flood geology."
Can anyone explain to me how these fossils were formed? Thank you.
