Abstract: A new species of Pliopithecus - P. bii sp. nov., is erected on dental morphology of m2~m3 and a central lower incisor, which were collected from the early Middle Miocene Halamagai Formation of Tieersihabahe in the northern Junggar Basin of Xinjiang Uygur Autonomous Region, China. The new species is especially characterized by a deep buccal funnel, which is enclosed by the cristid obliqua, the crest descending along the buccal slope of protoconid, and the buccal branch of prehypocristid. One P4 collected from near the same locality is assigned to Pliopithecus sp. because of its smaller size in relation to the m2 and m3. The associated mammal fauna of P. bii is approximately comparable to Tongxin fauna. Consequently P. bii is of early Middle Miocene in age, equivalent to the European Neogene land mammal age MN6. The high similarity between Dionysopithecus shuangouensis and Pliopithecus especially P. bii supports the inference made by Harrison and Gu (1999) that pliopithecini (Pliopithecus) was derived from an Asian rather than an African source.
摘要: 1997 和1998 年的野外工作期间,在新疆准噶尔盆地北缘铁尔斯哈巴合中中新世哈拉玛盖组的底部第二砂层中发现了4 枚上猿牙齿。两枚显然是属于同一个体的左m2 和m3 发现于98017 地点,地理坐标为46°39. 997′N ,88°30. 412′E。另一枚左下第一门齿和左上第四前臼齿产自该地点附近的同一砂层中。这是在中国境内、也是亚洲的第二个上猿化石地点。 该4 枚牙齿中,下门齿可能与m2、m3 属同一个种。m2 刚开始经受磨蚀,m3 则刚萌出齿槽。它们不同于所有已知种 (P. zhanxia
