The material described in this paper was collected from Hutouliang, Yangyuan county, Hebei, China it includes a nearly complete lower jaw with all cheek teeth (IVPP V 6769-3), the left P2-M3(V 6769-1), right P4-M3(V 6769-2), second and third right metacarpals (V 6769-5 and V 6769-4). Besides the characters of high-crowned cheek teeth with dense wrinkles on labial wall, strong crochet and crista, and the absence of antecrochet which can be grouped under Coelodonta antiquitatis, the material described here is characteristic of some features as: the largest tooth of upper cheek teeth M2 is nearly equal to M3, with a column tubercle in medisinus in M3 and short column tubercles in talonid grube of right m3.展开更多
