Sauropsida
Sauropsids make up the majority of chordate life in the Different World. The survival of many lineages that went extinct ages ago accounts for this more reptilian diversity than what happened on our world. Many species, genuses and families echo familiar lifeforms on Home Earth. In some, these echoings are due to actual evolutionary correspondence; the quasi-birds contain many members that are almost, but not quite, entirely identical to modern Passeriformes, however they also hold many tailed, clawed and toothed members amongst their ranks. In other cases, the similarities are superficial; one could quite easily mistake a Diff Geico for an Earth Gecko, or a Diff. Arbok for an oddly coloured Earth Cobra, however a quick look at the skull showing the lack of mobile articulations between the palate and braincase, would prove such thoughts wrong. Others most certainly have no such echoes. Anyone who mistakes a Raiusuchid for a crocodile will recieve funny looks, and someone who so much as dares to call a Ctenosauriscid a 'Dimetrodon' will probably be slapped by the nearest Diff. Biologist.
