Extinct clade of dicynodonts From Wikipedia, the free encyclopedia
Therochelonia is a group of dicynodont therapsids. The group was named by British paleontologist Harry Seeley in 1894 and fell into disuse in the following century. Therochelonia was redefined as a node-based clade in 2009. It is defined as the last common ancestor of Cistecephalus microrhinus and Dicynodon lacerticeps, and all of its descendants.[1] Below is a simplified cladogram from Kammerer et al. (2011) showing the phylogenetic placement of Therochelonia:[2]
