Resumen:
This presentation focuses on the study of lithic raw material distribution and morphological variations in lithic projectile points during the Late Holocene in Tierra del Fuego (Patagonia, Southernmost South America). The main goal of our study is to explore and discuss the regional distribution of some raw materials with focal availability, and the spatial patterns of projectile point size and shape variation throughout the Grande Island and neighboring areas. Raw material study is based on petrographic, geochemical and technological analyses. Projectile point size and shape variations, as well as its geographical patterns of distribution, are assessed through geometric morphometrics and spatial analyses. The results of raw material analyses points to the existence of a wide social network that integrated distant spaces within the Island, archipelago and the mainland. In contrast, despite the short geographic distance recorded among some of the samples considered, there are significant differences in projectile point variations, which exhibit spatial structuration. These results highlight the different scales of social boundaries and interaction among Fuegian hunter-gatherer populations during the Late Holocene.
