Dating of Cueva Cacao (NW-Argentina) sediments: hints for an early human occupation?

到目前为止，已知的是，从非洲开始，解剖学上的现代人的传播直到14000年后才到达南美大陆。我们当地的合作伙伴在阿根廷西北部的“Cueva Cacao”发现了人类头发化石，这可能暗示着更早的占领(43,000英镑)。利用来自洞穴沉积物不同层的一系列放射性碳测年，包括含有化石毛发的那一层，我们想要研究这些沉积物的地层学。这一结果可能证明了早期人类对该洞穴的占领。

So far it is known, that starting in Africa, the spread of anatomically modern humans took until 14,000 years before they reached the south American continent. Fossil human hair, which was found by our local cooperation partners in the "Cueva Cacao" in northwestern Argentina, may hint to a much earlier occupation (>43,000). Using a series of radiocarbon datings from different layers of the cave sediments, including the one containing the fossil hair, we would like to study the stratigraphy of these sediments. The results may prove the early human occupation of that cave.
