Sauropsids are vertebrate animals. They are one of the two groups which evolved from egg-laying amniotes in the first part of the Carboniferous period. The Sauropsida includes all modern and most extinct "reptiles" and birds.[1][2][3]
The synapsids are the other group which evolved from amniotes. They gave rise, eventually, to the mammals.
Living sauropsids include lizards, snakes, turtles, crocodiles, and birds. Extinct sauropsids include non-avian dinosaurs, pterosaurs, plesiosaurs, ichthyosaurs, and many others.
