title: The earliest elephant-bone tool from Europe: An unexpected raw material for precision knapping of Acheulean handaxes
abstract: 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 typi
