Study of the weapon systems employed by hunter-gatherers of the Argentinian Pampean región. Arroyo Seco 2 site.The site Arroyo Seco 2 (Tres Arroyos county, Buenos Aires province) is one of the most ancient sites in South America. The research carried out in this site allowed us to obtain a solid chronological and stratigraphic base to characterize human occupation during the final Pleistocene (ca. 14.000 years cal BP) and at different times during of the Holocene. In this work we present the results from the tecno-funtional analyses of projectile points recoverd in different contexts. Some of them are associated to human burials (dated ca.7800 years cal BP) and other recovered at Y and X stratigraphic units, assigned to the Middle and Late Holocene. Technological differences among the artifacts can be related not only to their function use context but also to the chronology. Starting from these analyses, we seek to explore the different social and symbolic dimensions that these artifacts had for hunter-gatherers inhabiting the site. Data obtained provide information about different issues of interest for anthropology and archaeology, i.e., the technological identity of human groups as well as the different social interactions that were established between groups and their territory.
