Exploring for Paleogene Primates in Bolivia

该项目的主要目标是寻找网站 包含了南部中第三纪的灵长类化石 美国参考 长期以来，人们一直在争论， 高等灵长类动物出现在新旧大陆。 虽然 在旧世界有重大发现， 美洲的早期高等灵长类进化很少。 一 一个有待回答的主要问题是原猿类是否 在新的世纪里， 还是曾经发生过 在后一种情况下 它们最后的共同祖先 猴子. 调查人员已经确定了玻利维亚的地质沉积 有希望发现这一时期的化石 与 玻利维亚地质调查局的协助下， 寻找这个时期的化石

The primary objective of this project is to search for sites containing primate fossils from the middle Tertiary in South America. There has long been debate as to the path by which the higher primates appeared in the Old and New World. While there have been significant discoveries in the Old World, knowledge of early higher primate evolution in the Americas is scant. A principle question that remains to be answered is whether prosimian grade primates evolved into a monkey grade independently in the New and Old Worlds or whether this occurred once. In the latter case the last common ancestor of the two would have already have been monkey. The investigators have identified geological deposits in Bolivia which show promise of bearing fossils from this time period. With the assistance of the Bolivian Geological Survey they will search for fossils from this time period.
