All right, all right, I goofed!!! My knowledge of subdivision terms is
shaky at best. I am not suggesting that dinos belong outside of the
vertebrates. The point I hoped to make was that I place the terms
Archosauria and Dinosauria IN BETWEEN the major subdivision of Phylum and
Class (it just became a lot closer to Class:-). Under this system, I have
no difficulty seeing Aves placed at the same level with Saurischia and
Ornithischia (acknowledging their common ancestry while showing their
