项目摘要

I have gathered the paleontological data of the Neogene (the late Miocene through the early Pleistocene) Old World monkeys (Family Cercopithecidae) in the Eurasian continent, and reviewed the information on the locality, geological age, and phylogenetic position of the fossil taxa. It was previously believed that Old World monkeys have appeared in Europe first in the Eurasian continent. This hypothesis was criticized by the recent discovery of isolated molars of Macaca? from the latest Miocene beds (about 6 Ma) at the Yushe, Shangxi Province, China. The age of the Yushe teeth corresponds to that of the oldes fossil record in Europe. Moreover, the latitude of the Yushe locality is about 37°N, which is much northern part than other early Pliocene fossil localities in South Asia. These fossil evidences necessitate the reexamination of the traditional hypothesis on the evolutionary process of the Old World monkeys (Cercopithecoidea) in the Eurasian continent.In this work I have reviewed the recent paleontological data on the Old World monkeys in the Eurasian continent, making a database of the fossil specimens, locality, faunal lists, and paleoclimate. In addition, I published a preliminary review article on the evolutionary process on the cercopithecine monkeys (macaques and baboons) during the Neogene in the Eurasian continent (Takai, 2005). Now I am preparing another article on the evolutionary process of colobine monekeys during the Neogene I the Eurasia.

我收集了欧亚大陆新近纪（中新世晚期至更新世早期）旧大陆猴（猕猴科）的古生物学资料，并回顾了化石分类群的地理位置、地质时代和系统发育位置。以前人们认为，旧大陆猴最早出现在欧亚大陆的欧洲。这一假说受到了批评，最近发现的孤立臼齿的猕猴？山西榆社中新世晚期（约6Ma）地层中发现的一组化石。玉舍牙齿的年龄与欧洲最古老的化石记录相一致。此外，榆社化石地点的纬度约为37°N，比南亚其他早上新世化石地点偏北方。这些化石证据使我们有必要重新审视关于欧亚大陆旧大陆猴（Cercopithecoidea）演化过程的传统假说。本文回顾了欧亚大陆旧大陆猴的最新古生物学资料，建立了一个化石标本、地点、区系名录和古气候数据库。此外，我发表了一篇关于欧亚大陆新近纪猕猴（猕猴和狒狒）进化过程的初步评论文章（Takai，2005）。现在我正在准备另一篇关于欧亚大陆新第三纪的猴的进化过程的文章。
