陕西蓝田公王岭“蓝田伟猴”化石的再研究

蓝田公王岭动物群中,唯一的一种非人灵长类化石由胡长康、齐陶(1978)定名为Megamacaca lantianensis(蓝田伟猴)。但按其形态,我们觉得把它归于疣猴亚科比较适宜。特别是与该亚科中的金丝猴属(Rhinopithecus)更为相像,例如蓝田标本下颌支与下颌体垂直,冠状突略向后弯,齿尖起伏较大等都显示了金丝猴的一般性质。至此,本文将蓝田伟猴归于金丝猴属,保留原有种名:Rhinopithecus(Megamacaca)lantianensis(Hu and Qi)。时代为早更新世晚期。

A REASSESSMENT OF MEGAMACACA LANTIANENSIS OF GONGWANGLING, SHAANXI PROVINCE

One new species of fossil Primates in the fauna of Gongwangling, Lantian County was described by Hu and Qi (1978). They assigned the fossil to the species Megamacaca lantianensis. When we compared it with fossil monkeys from other localities we found that Megamacaca lantianensis should be attributed to the subfamily Colobinae, owing to the higher molar relief, shorter trigonid in the lower molar than Cercopithecinae and other features. There are more similarities in the teeth and jaws of Megamacaca with Rhinopithecus, but it is larger in size than any extant species of Rhinopithecus, its age is Early Pleistocene, therefore, we suggest to continue the species name. Thus the fossil primate of Lantian is named as Rhinopithecus (Megamaca-ca) lantianensis. Its body weight was estimated to be 14.3-17.9 kilograms.
