Bone retouchers from Lower Palaeolithic sites: Terra Amata, Orgnac 3, Cagny-l'Epinette and Cueva del Angel

Bone retouchers are more common during the Middle Palaeolithic (from MIS 7 to 3) and are now considered as a part of the tool kit of Neanderthals. In Middle Pleistocene and Lower Palaeolithic assemblages, they are few in number and attest to the scarcity of use of bones as material for shaping tools. Some MIS 11 to MIS 9 sites allow the description of the onset of bone use and its multiplication after the MIS 9 attests of another functional relationship between bones and hominins.
