Abstract: A human tooth and some mammalian fossils were collected from the Yaotouguo- valley about 2 kilometers to the southwest of the Changwu Xian, Shaanxi in October, 1972. The mammalian remains include Myospalax sp., Coelodonta sp., Equus cf. przewdlskii, Equus hemionus, Megaloceros (Sinomegaceros) sp, Cervus (Pseudaxis) sp., Bovinae indet. The fossil assemblage indicates clearly that it is of Upper Pleistocene in age. The human tooth is quite similar to that of modern human in size and its fea_x001F_tures. We attributed it to Homo expiens in classification.
