BIOARCHAEOLOGICAL ANALYSIS AT LOTEO SILVA SITE. NEW CONTRIBUTIONS FOR THE LOWER VALLEY OF THE NEGRO RIVER (VIEDMA, RIO NEGRO PROVINCE)

Abstract

The bioarchaeological analysis of the human remains rescued at Loteo Silva site (Viedma, Río Negro province) is presented, with the objective of characterizing and evaluating funerary practices, site functionality, paleodiet, and discussing the chronology of hunter-gatherer occupations from the lower course of the Negro River. In addition, this context is discussed and inserted in the archaeology of the study area and surrounding microregions (e.g., eastern Pampa-Patagonia transition, northern coast of San Matías Gulf). The results indicate the presence of three adult individuals of both sexes, buried in both simple primary and secondary modalities. The taphonomic studies show the stability in the post-depositional history and the exposure of the skeletons at moments close to their actual recovery. Stable isotope analysis indicates that mainly terrestrial resources were consumed by these individuals. Two radiocarbon dates showed a chronology of ca. 3.600-3.200 years BP, indicating the earliest occupation for the lower course of the Negro River and the earliest evidence of burial manipulation from the Northeastern Patagonia. The burials recovered at Loteo Silva site presents trends and characteristics similar to other mortuary contexts of the study area and neighboring regions.
