Grotte du Renne
The Grotte du Renne (French for "Reindeer's cave") is one of the many caves at Arcy-sur-Cure in France, an archaeological site of the Middle/Upper Paleolithic period in the Yonne departement, Bourgogne-Franche-Comté. It contains Châtelperronian lithic industry and Neanderthal remains. Grotte du Renne has been argued to provide the best evidence that Neanderthals developed aspects of modern behaviour before contact with modern humans, but this has been challenged by radiological dates, which suggest mixing of later human artifacts with Neanderthal remains. However, it has also been argued that the radiometric dates have been affected by post-recovery contamination, and statistical testing suggests the association between Neanderthal remains, Châtelperronian artefacts and personal ornaments is genuine, not the result of post-depositional processes.
