El instrumento de hueso de elefante más antiguo de Europa: una materia prima inesperada para el tallado de precisión...

Organic knapping tools made from bone, antler, and wood were essential to early human toolkits but are rarely preserved in the archeological record. The earliest known soft hammers, dating to ~480,000 years ago, come from Boxgrove (UK), where modified antlers and large mammal bones were used alongside flint hard hammers. These tools facilitated complex knapping techniques, such as platform preparation and tranchet flake removal, contributing to the production of finely worked ovate handaxes typical of the Boxgrove Acheulean industry. This study presents a cortical bone fragment from an elephant, deliberately shaped into a percussor for resharpening flint tools. It represents the earliest known use of elephant bone in Europe and the first documented case of its use as a knapping hammer. Reconstructing its life history offers further insights into Middle Pleistocene hominin technological adaptations, resourcefulness, and survival strategies that enabled humans to endure harsh northern environments.
