Saurians

Saurians, a general term applied to more or less lizard-like fossils, some of which are Amphibia, though the majority are reptiles, and some of which attained enormous dimensions. The Labyrinthodont Archegosaurus from the Carboniferous system, and the Mesozoic Ichthyosauria, Plesiosauria, Pterosauria, and Dinosauria, most of which are noticed separately, are among the chief types.
