Collaborative Research: Paleontological Investigations to Recover Fossil Monkeys from the Cenozoic of South America

小行星9318942 新世界猴的祖先在新生代早期的某个时候到达了南美洲，但由于化石记录不足，只有间接的证据表明何时何地-直接来自非洲的可能性仍然很大。 南美洲最早的记录发生在玻利维亚的萨拉，可以追溯到大约2500万年前。 这项合作性实地项目的目标是在萨拉和可能在玻利维亚的其他地方收集更多关于南美洲最早的灵长类动物的材料，并准确地确定它们的年代，同时探索阿根廷类似年龄的地层，以及更早的地层，在那里很可能会发现祖先的形式，这项项目将为这些灵长类动物的起源提供急需的线索，这些灵长类动物与我们在非洲的祖先是平行进化的。 ***

9318942 Kay Forbears of New World Monkeys reached South America some time in the early Cenozoic, but because of an inadequate fossil record there are only indirect lines of evidence about when or from where - direct from Africa remains a distinct possibility. The first record of them in South America occurs at Salla, Bolivia, and dates to about 25 million years ago. The goal of this collaborative field project is to collect and date accurately more material of the earliest South American primates at Salla and possibly elsewhere in Bolivia and to explore Argentina strata of similar age, and earlier, where it is very likely ancestral forms should be found. This project will shed much needed light on the origins of these primates who evolved in parallel with our own ancestors in Africa. ***
