Sanchuansaurus is an extinct genus of pareiasaur from the late Permian Sunjiagou Formation of China. The genus contains a single species, S. pygmaeus, known from a partial maxilla and left leg bones.[2] A 2013 study suggested that both Sanchuansaurus and another Chinese pareiasaur, Huanghesaurus, were synonymous with Shansisaurus.[3] However, this has not been followed in future research, with later papers considering Sanchuansaurus to be distinct, with Huanghesaurus and Shansisaurus possibly being synonymous with Shihtienfenia, another Chinese pareiasaur.[1]
