Wangwusaurus
Wangwusaurus is extinct genus of probable therapsid that lived in the Late Permian in present-day China. Only species is known, Wangwusaurus tayuensis, described by the paleontologist Yang Zhongjian in 1979 from seventeen teeth found in the Jiyuan formation, of which at least seven are recognized as not belonging to those of therapsids.

Description
One of the teeth found also has characteristics similar to those of gorgonopsians, which earned the chinese paleontologist Yang Zhongjian to classify him as the first member of this group to have lived outside of Russia and Africa, places where they are officially recognized.[1][2] However, three years later, in 1981, palaeontologists Denise Sigogneau-Russell and Ai-Lin Sun found the assigned material to be a random assemblage of which only two have even a remote similarity to gorgonopsians, making its classification uncertain.[3]
