The Origin of Reptiles

The Origin of Reptiles The two clades of Reptiles, Lepidosauromorpha (in gray on the left) and the Archosauromorpha (in white on the right) descend from a tiny species of Gephyrostegus watsoni and other pre-reptiles. Diadectomorphs and microsaurs both now nest within the Reptilia.
