L’approvisionnement en matières premières lithiques au Pléistocène inférieur et moyen dans la Sierra de Atapuerca, Burgos (Espagne)

This paper summarizes the latest studies on lithic raw material raising that are currently undertaken within the Sierra de Atapuerca research project. During the past two years, several works have provided new petrographical and technological data, contributing to the knowledge of the kinds of materials exploited by the Atapuerca hominids, as well as the areas where those materials were raised. The sites yielding this information are Gran Dolina (Lower and Middle Pleistocene) and Galeria (Middle Pleistocene), both located in the Trinchera del Ferrocarril archeopaleontological complex.
