Casea broilii (Romer 1937) Kungarian, Early Permian ~275 mya, ~ 1.2 m in length, was an herbivorous reptile typically lumped in with pelycosaurs like Archaeothyris and Varanops. Here a larger dataset derives Casea from a sister to Ennatosaurus and basal to Cotylorhynchus.
Distinct from Ennatosaurus, the skull of Casea had a larger orbit. The skull was relatively wider and the bone was pitted. The teeth were long and blunt.
The cervicals were shorter, the dorsal ribs enclosed an enormous torso. The caudals were long and the tail tapered gradually.
The pectoral girdle was more gracile. The ilium was broad with a large anterior process . The limbs were more gracile and the hind limbs were sprawling. The digits were much longer than the metatarsals.
