PLEISTOCENE MAMMALS FROM TUNLIU,SHANXI

The collections of mammalian fossils described in this paper were collected by the geological team of Shanxi and a feild team of IVPP from Tunliu, Shanxi, in 1974, 1975 and 1978. The mammalian fossils consist of the following species:Trogontherium sp. Equus sanmeniensis T. et P.Myospalax tingi Young Coelodonta antiquitatis BlumenbachCanis variabilis Pei Sus lydekkeri ZdanskyUrsus thibetanus Cuvier ?Axis sp.Meles cf. leucurus Hodgson Cervinae gen. et sp. indet.Felis teilhard Pei Gazella sp.Archidiskodon sp. Bison sp.As can be seen from the above list that the mammalian fossils are one of the middle Pleistocene stage. In comparison with the Choukoutien they are strengthened by the presence of Archiskodon sp. and ?Axis sp. which are absent in the type locality of middle Pleistocene. The structure of the molar in general resembles that in Sus lydekkeri, but it is evidently more primitive than the species known from Choukoutien. So these fossils from Xiao Chang-cun are earlier than the Choukoutien and may be early in the middle Pleistocene.
