Casea
''Casea'' is an extinct genus of pelycosaur synapsid which was about long, slightly smaller than the otherwise very similar ''Caseoides''. ''Casea'' was one of the first terrestrial herbivores, sharing its world with animals such as ''Dimetrodon'' and ''Eryops''. ==Description==
''Casea'' had a heavy, rotund, body and a small skull. Its rib cage was greatly expanded, presumably to make space for a large, plant-fermening gut. Like other caseids, it lacked teeth in its lower jaw, and had blunt teeth in the upper jaw. These adaptations indicate that ''Casea'' was a herbivore, feeding on relatively tough plants, such as ferns.
