Paleodietas humanas en la costa patagónica durante el Holoceno tardío : Nuevos datos de isótopos estables y fechados radiocarbónicos para la costa centro-sur

Abstract

El objetivo de este trabajo es presentar datos de isótopos estables de la fracción colagénica (ä13C y ä15N) y fechados radiocarbónicos de una muestra de restos óseos humanos de la costa sur de la actual provincia del Chubut. Los datos obtenidos se discuten en términos de paleodietas en el contexto de investigaciones previas y datos disponibles para el resto de la costa atlántica patagónica. La expectativa inicial fue hallar dietas caracterizadas por un consumo mixto de recursos (i.e., marinos y terrestres). Sin embargo, sólo una de las muestras analizadas sugiere el consumo de recursos marinos, cuya antigüedad es de 2531 ± 45 años AP. Las restantes indican un consumo de recursos predominantemente terrestres con valores semejantes a los relevados en el interior patagónico. Con este trabajo se espera aportar a la discusión regional sobre paleodietas humanas entre los grupos cazadores-recolectores de la costa durante el Holoceno tardío.

The goal of this paper is to present stable isotope data from collagen (ä13C and ä15N) and radiocarbon dates of a sample of human skeletal remains from the southern coast of Chubut Province. The data are discussed in relation to paleodiets and in the context of previous research and available data for the rest of the Atlantic Coast of Patagonia. The initial expectation was to find diets characterized by mixed consumption of resources (i.e., marine and terrestrial). However, only one case, dated 2531 ± 45 years BP, suggests the consumption of marine resources. The remaining samples show consumption of predominantly terrestrial resources with similar values to those of inland Patagonia. This paper contributes to the discussion of regional human paleodiets among coastal late Holocene hunter-gatherers.
