Explotación de materias primas líticas en el sector sur de la ría Deseado: análisis de núcleos procedentes de Bahía del Oso Marino (Patagonia argentina)

this paper explores the existence of variation in lithic raw materials exploitation strategies in bahía del oso marino, located south of the river deseado. the study was conducted on cores collected from surface and stratigraphic sites; it took into account differences in reduction techniques and distances to potential sources of lithic procurement. the results suggest the existence of variability in the strategies of lithic resource exploitation in the southern sector of the river deseado. among other significant factors are the characteristics of available lithic raw materials sources in this space, which is seen in the raw materials economic strategies adopted. the influence of such variation in relation to the range of mobility and lithic procurement strategies used by hunter gatherers who occupied the area south of the river deseado during the middle and late holocene is discussed.
