Category:Caseasaurs

Caseasauria is one of the two main clades of early synapsids, the other being the Eupelycosauria. Caseasaurs are currently known only from the Late Carboniferous[1] and the Permian, and include two superficially different families, the small insectivorous or carnivorous Eothyrididae, and the large, herbivorous, potentially aquatic[2] Caseidae. These two groups share a number of specialised features associated with the morphology of the snout and external naris.
