As part of a series of research projects on the Archaeology of hunter-gatherers societies in the Southern Pampean Hills this presents, among other things, the study of various aspects of the organization of lithic technology and strategies for the use of lithic resources by prehistoric populations. This is in order to understand the social aspects that allow us to recognize and describe habitus or ways of doing things. In this book we studied lithic assemblages, in the manner described above from stratigraphic levels of the Alero Deodoro Roca (Deodoro Roca Rockshelter) comprising chronologies between ca. 3000 years BP to ca. 3600 years BP. We propose that behind the technical movements, organization of the production, distribution of activities in space, the selection of raw materials and any other technological activity, there are people and groups who make decisions based on the context, needs, history and knowledge. We ask ourselves: What affected material selection for the production of stone tools rocks? Was there a differential selection depending on the desired end product? And if so, was it different in diachronic moments? What techniques were used in the production of what instruments? What productive activities were conducted in Alero Deodoro Roca and which were not? What role did the tools produced have? This study aims to produce relevant and new information that expands our knowledge of technological strategies used by the human groups in order to compare them with those produced in other areas of the Sierras. It will contribute to a process of constructing knowledge about hunter-gatherers of the valleys of Cordoba province, by studying lithic technology and therefore raising new questions for further studies.
