Casea is a genus of herbivorous caseid synapsids that lived during the late Lower Permian (Kungurian) in what is now Texas, United States. The genus is only represented by its type species, Casea broilii, named by Samuel Wendell Williston in 1910.[1] The species is represented by a skull associated with a skeleton (the holotype FMNH UC 656), a second skull (FMNH UC 698), a partial skull with a better preserved dentition than that of the preceding skulls (FMNH UC 1011), and several incomplete postcranial skeletons.[2] Three other Casea species were later erected, but these are considered today to be invalid or belonging to different genera.[3][4][5] Casea was a small animal with a length of about 1.20 m and a weight of around 20 kg.[6][7]
