Urumchia
''Urumchia'' is an extinct genus of therocephalian therapsid from the Early Triassic of China. The type species ''Urumchia lii'' was described by Chinese paleontologist C. C. Young (Yang Zhongjian) in 1952 from the Jiucaiyuan Formation in Xinjiang. The holotype skull has been lost, but Young was able to describe the species on the basis of a detailed cast of the skull. ''Urumchia'' is similar to the South African therocephalian ''Regisaurus'' in having an expanded pair of vomer bones on the underside of the skull that form a secondary palate. In ''Urumchia'' the front end of the vomers narrow to a point, while in ''Regisaurus'' they do not. ''Urumchia'' has six incisors on either side of the upper jaw, a primitive condition among baurioid therocephalians that usually have fewer incisors.〔 ==References==
