Abstract

TERRANOVA, Enrique D.. ANALYSIS OF DEBITAGE FROM AMIGO OESTE SITE (SOMUNCURÁ PLATEAU, RÍO NEGRO PROVINCE). CONTRIB UTIONS TO THE KNOWLEDGE OF THE LITHIC PRODUCTION PROCESS. Relaciones [online]. 2021, vol.46, n.1, pp.161-180. ISSN 0325-2221.

This work represents an improvement in the understanding of lithic artifact production processes at the Amigo Oeste site, located on the Somuncurá plateau (Río Negro, Argentina).

This site has a surface assemblage characterized by several Fishtails points, which link its chronology to the Pleistocene-Holocene transition during the early settlement of the area. Based on the techno-morphological study of the debitage retrieved in systematic transect survey, we propose that knapping and final sharpening of tools were the main activities that took place in this site. This new information reaffirms the idea that Amigo Oeste was a meeting place of hunter-gatherer societies where replacement, re-equipment and final production of Fishtail points were carried out.

Keywords : lithic debitage; nordpatagonia; hunter gatherers; early settlement; Fishtail Point.
