Captorhinidae

Captorhinidae (also known as cotylosaurs, root reptiles or stem reptiles) is one of the earliest and most basal reptile families.
Captorhinids are a clade of small to very large lizard-like reptiles that date from the late Carboniferous through the Permian. Their skulls were much stronger than those of their relatives, the Protorothyrididae, and had teeth that were better able to deal with tough plant material
