AI Article Synopsis
- * Excavations and advanced dating at the Campo Laborde site provide strong evidence against the idea that these giant mammals survived into the Holocene, showing they likely went extinct earlier.
- * The findings document direct human activities, such as hunting and butchering of megafauna like the giant ground sloth, dating back to around 12,600 years ago.
Article Abstract
The extinction of Pleistocene megafauna and the role played by humans have been subjects of constant debate in American archeology. Previous evidence from the Pampas region of Argentina suggested that this environment might have provided a refugium for the Holocene survival of several megamammals. However, recent excavations and more advanced accelerator mass spectrometry radiocarbon dating at Campo Laborde site in the Argentinian Pampas challenge the Holocene survival of Pleistocene megamammals and provide original and high-quality information documenting direct human impact on the Pleistocene fauna. The new data offer definitive evidence for hunting and butchering of (giant ground sloth) at 12,600 cal years BP and dispute previous interpretations that Pleistocene megamammals survived into the Holocene in the Pampas.
