项目摘要
The objective of this project is to recover fossil monkeys in middle Tertiary rocks in Argentina and Bolivia and to place known and new specimens within a more refined chronological framework. Recovery of older monkeys from South America (SA) will contribute important new information to the adaptations of early SA monkeys (also called platyrrhines). New material will shed light on how the relationship of species of monkeys from South America and African. Also, new fossil remains will help to refine our understanding of the origins of the major kinds of platyrrhines, all of which trace back to a common ancestor thought to have lived about 20 million years ago. Finally, new fossil primates may further constrain the time of entry of platyrrhines into South America.The researchers will collect in three areas: 1) the 26 million-year-old rocks of Bolivia which yield the oldest known South American primates; 2) a newly discovered 25 million-year-old locality in the southern Altiplano of Bolivia; 3) Patagonian sites dated at around 20 million years old that contain monkeys and other small mammals; and 4) earlier fossil sites in Patagonia and northern Argentina that preserve small mammals (but not monkeys, as yet) but had a favorable paleoclimate for the occurrence of monkeys and are presently inadequately explored. Rock samples will be collected for 40Ar/39 age determination.
该项目的目标是在阿根廷和玻利维亚中第三纪岩石中发现猴化石,并将已知和新标本置于更精确的年代框架内。来自南美洲(SA)的老年猴的恢复将为早期SA猴(也称为阔鼻猴)的适应提供重要的新信息。新的材料将阐明来自南美洲和非洲的猴子物种之间的关系。 此外,新的化石遗骸将有助于完善我们对主要种类的阔鼻龙起源的理解,所有这些都可以追溯到大约2000万年前的共同祖先。 最后,新发现的灵长类化石可能进一步限制了阔鼻类进入南美洲的时间。研究人员将在三个地区收集:1)玻利维亚的2600万年前的岩石,那里是目前已知最古老的南美洲灵长类; 2)玻利维亚南部阿尔蒂普拉诺的一个新发现的2500万年前的地点; 3)巴塔哥尼亚遗址,距今约2000万年,有猴子和其他小型哺乳动物;巴塔哥尼亚和阿根廷北方保存小型哺乳动物的早期化石遗址(但不是猴子,到目前为止),但有一个有利的古气候为猴子的出现,目前还没有充分的探索。 将采集岩石样品进行40 Ar/39年龄测定。
