caption_attribution_description: A Middle Triassic cynodont Diademodon
context_page_description: Diademodon is an extinct genus of cynodonts. It was about 2 metres long. Although Diademodon is the most well accepted name for the genera to date, it was originally named Cynochampsa laniarius by Owen in 1860. The proposed name change occurred in 1982, where Grine defended the name proposed by Harry Seeley: Diademodon tetragonus and to be place in the group Therapsida, which was a group Owen had tiptoed around in his works on paleontology. Though Harry Govier Seeley had named Diademodon in 1894, which was after Owen had dubbed the genus Cynochampsa, Seeley had not realized the two were one and the same as the fossil that Owen named was claimed to have been found in a claystone nodule in the Renosterberg Mountains. A later paleontologist explored the same area where the fossil was claimed to have been found and declared no evidence of Cynognathus fossils.
