Además se crea un modelo estadístico de clasificación mediante análisis discriminante lineal, support vector machines y k-nearest neighbour que nos permite diferenciar los sílex en función de su edad de formación.; Microscopy, mass spectrometry and X-ray diffraction methods were used to analyse 415 samples of natural and archaeological flint from Sierra de Atapuerca (Burgos, Spain) in order to characterize the different types from Neogene and Cretaceous formations in the study area, infer their genetic context and ascertain the supply sources used by hunter-gatherers who exploited this area in the Upper Pleistocene. A statistical classification model was also designed using linear discriminatory analysis, support vector machines and k-nearest neighbour which permitted the differentiation of the flint based on their age of formation.

Several archaeological excavations have yielded a large number of lithic elements and a smaller amount of bones. This assemblage has permitted the characterization of the “Quina Mousterian”. However, neither a study of the provisioning systems and lithic exploitation methods nor an analysis of the bone remains have ever been done to define the degree of human involvement in the formation of the sites. This paper analyzes these aspects, including unpublished archaeological material and focusing on the use of the biotic and abiotic resources. We compare the two sites and propose a functional interpretation linked to seasonality and the special treatment of hides and leather.
