Dated evidence of the interaction between humans and megafauna in the late Pleistocene of Sergipe state, northeastern Brazil

摘要

We present a radiocarbon date (12,742-12,562 cal BP) for an Eremotherium laurillardi tooth found in Sergipe state, northeastern Brazil, which shows anthropogenic marks. Our result provides additional information and reinforces the hypothesis that humans was present in South America earlier than accepted currently, and interacted with megafauna during the late Pleistocene in this region.
