Abstract: Since 1990, several plesiadapiforms have been found from the coal beds of the Wutu Coal Mine of Changle County, Shandong Province. Chronolestes simul and Carpocristes oriens, allocated to the family Carpolestidae were described by Beard and Wang (1995). In this paper, a new plesiadapiform, Asioplesiadapis youngi, is reported, and is referred to the family Plesiadapidae, based on its long, robust procumbent lower incisor, with margoconid and margocristid, and on dental morphology.

摘要: 记述了山东五图盆地早始新世五图组的一种更猴类(plesiadapid) 化石:杨氏亚洲更猴(Asioplesiadapis youngi gen. et sp. nov. ) 。在它增大的下门齿上具有更猴科特有的下缘尖和下缘脊,但其下颊齿性状相当原始,p4 跟座呈盆状,m3 下次小尖呈锥状更类似白垩纪晚期出现的更猴形动物Purgatorius 。Asioplesiadapis 的下臼齿形态可以说明亚洲更猴类虽然有北美和欧洲更猴的某些典型特征,但并不在同一进化支系。因此,另立一新亚科——亚洲更猴亚科(Asi
