Phylogenetic Study of South American Monkeys

本研究的目的有两个：首先，通过形态学方法，获得现存南美猿类，特别是已发现直接古化石的Alouatta、Saimiri、Cebus和Aotus之间的分类关系的基本资料；二是通过对中新世灵长类动物的古生物发掘，获得南美猴系统发育的基础资料；二是通过地质方法，收集中新世灵长类动物生活的绝对年龄和古环境的基本信息。古生物学和地质研究将在哥伦比亚韦拉省的半沙漠地区进行，自1979年以来，我们已经在那里发现了灵长类动物化石。南美洲现存猴子的比较研究将在巴西的几个博物馆进行，如里约热内卢灵长类动物中心，贝伦和玛瑙斯的自然历史博物馆。化石和活体南美猴子的比较研究将在阿根廷、巴西、玻利维亚和美国的几所大学和机构进行。

The purpose of the present research is two-fold : First to get the basic data for the taxonomic relationships among the living South American Monkeys, especially Alouatta, Saimiri, Cebus and Aotus of which the direct ancient fossils were already discovered, by means of morphological methods, and second to get basic data for the phylogeny of the South American Monkeys by means of paleontological excavation of the Miocene primates and to gather the basic information about the absolute age and paleo-environment of which Miocene primates inhabited by means of geological methods.The paleontological and geological researches will be done in the semidesert area in the Huila Department of Colombia, where we have already discovered fossil primates since 1979. The Comparative studies of living South American monkeys will be done in the several museums in Brasil, such as Primate Center of Rio de Janeiro, Natural History Museums of Beren and Manaus. The comparative studies between fossil and living South American monkeys will be done in the several universities and institutions in Argentina, Brasil, Bolivia and USA.
