The management of lithic resources during the V millennium cal BC at Espluga de la Puyascada (La Fueva, Huesca)

Although the archaeological site of Espluga de la Puyascada was only excavated during one campaign (1975), this cave might be considered one of the most significant sites in the pre-Pyrenean mountains of Huesca. The materials found in the survey excavation provide several information about the economy of the pastoral and agricultural groups living in the area during the V millennium calBc. the results of the analysis of the lithic assemblage, and its petrological, technological and functional characterisation, are presented in this paper. the data obtained indicates that the lithic implements were mainly constituted of blade blanks, which production was based on the procurement of raw materials in a regional context over a distance of about 80-90 kilometres. the lithic tools were used in productive processes associated with both the acquisition of food and the manufacture of other implements and goods.
