OCUPACIONES HUMANAS EN LA COSTA ATLÁNTICA DE TIERRA DEL FUEGO DURANTE EL HOLOCENO TARDÍO.

Human Occupation on the Atlantic Coast of Tierra del Fuego During the Late Holocene We present the results of research undertaken at three archaeological sites, Okon XXI, Teis X and Teis XI, located on the Atlantic coast of Tierra del Fuego (Patagonia, Argentina) and dating to the Late Holocene. Teis X and Teis XI are dome-shape shell middens whereas Okon XXI is a shell lens barely visible from the surface.We hope to identify trends in the use of the landscape based on the analysis of processes of production and consumption as well as their intra-site spatial distributions. The morpho-technical and usewear analyses of lithic assemblages allow us to detect similarities in raw material exploitation and artifact manufacture techniques and differences related to spatial organization and activities distributions. Consequently, a heterogeneous use of the coastal landscape is proposed as well as broad, regional circulation of technological knowledge. [ABSTRACT FROM AUTHOR]
