Abstract
Archeological findings in central and southern Patagonia indicate that highly mobile hunter-gatherers swiftly settled in the cold and treeless late-Pleistocene steppes as early as 13 000 cal a BP. In southern Patagonia, the faunal assemblages from these initial sites have helped clarify taxonomic issues, explore the timing of megafaunal extinction, and reconstruct the paleoecological dynamics involving extinct and extant taxa and humans. Nonetheless, essential aspects such as subsistence strategies and the mobility of these early inhabitants have been less thoroughly studied. This paper offers a detailed zooarchaeological and taphonomic analysis of the faunal remains from late Pleistocene archeological sites Cueva Lago Sof & iacute;a 1 in the & Uacute;ltima Esperanza area and Tres Arroyos 1 rock shelter in northern Tierra del Fuego. We identified at least 17 taxa, including both extinct and living species; taphonomic evidence suggests that Canidae and Camelidae were the primary groups exploited. Extinct taxa probably served as supplementary resources. We propose that Cueva Lago Sof & iacute;a 1 functioned as a logistic camp for animal processing, while the faunal evidence from Tres Arroyos 1 aligns with a small base camp that was recurrently occupied. The results are compared with other contemporary sites in Patagonia and discussed in the context of human exploration models and spatial usage proposed for the region
