Les matières premières,la technologie lithique et les stratégies d’occupation dans le site du Pléistocène moyen de Covacha de los Zarpazos (gisement de Galería,Sierra de Atapuerca,Espagne)

Variability is one of the most debated topics in lithic technology studies. For the Middle Pleistocene period, this debate has specifically focused on the significance of large cutting tools such as handaxes and cleavers. This paper presents the stone tool assemblage from Covacha de los Zarpazos site, included in the Galería complex at Sierra de Atapuerca (Burgos, Spain). We analyse the management of lithic raw materials, the reduction sequences identified, and the morphological variation in the shape of large cutting tools. The results show that raw materials play an important role in the final variability of tool shape, although they do not represent any real constraint. However, what determines the main variability of a whole lithic assemblage is the occupation strategy and the specific activities carried out in a given site.
