Caseopsis was a large pelycosaur that was about 3 meters long. Caseopsis lived in the late Early Permian epoch (Kungurian Age), before the pelycosaurs were replaced by the more advanced therapsids (in the next age). It was a lightly built, agile creature. It may have been possible for this species to outpace and escape large predators such as Dimetrodon.
