Caseoides was a large pelycosaur synapsid that lived in the Kungurian Age (late Early Permian epoch). It was about 3 meters long, and like many other caseids, it was herbivorous. It weighed between 150 kg to 200 kg. Its fossils were found on Texas. Caseoides was very similar to Casea, but was slightly larger in size. Caseoides was heavily built creature, as most of Caseids (except Caseopsis).
