Les silex et autres matières premières comme preuves de contacts entre les groupes de chasseurs-cueilleurs pendant le Paléolithique supérieur de la région cantabrique (nord de l’Espagne) : synthèse de l’information disponible

Flint was the most widely used lithic raw material in Europe in Prehistory and, more specifically, was a fundamental resource in the economic and social networks of hunter-gatherer groups in the Cantabrian Spain during the Upper Palaeolithic. The undeniable preference for it compared with other resources was due to a series of factors, such as its easy availability because of its abundance and wide distribution of outcrops, and its excellent qualities for knapping. This summary of the available information about flint and other raw materials used by hunter-gatherers is framed in the context of Upper Palaeolithic occupations in Cantabrian Spain. First, it presents the studies focusing on the provenance of the different types of flint that are found in those occupations; their quantitative representation at each of the sites; their preference, if that is the case, over other raw materials; and the model of their diffusion across the territory. Then other resources are considered, such as quartzite, ochre and different metamorphic, sedimentary and igneous rocks, as well as some materials of biological origin, such as amber, jet/lignite and fossils of animal origin. However, the information available about the use of the latter raw materials in Cantabrian Spain during the Upper Palaeolithic is quite limited and studies of their characterisation are very recent.
