SCABUZZO, Clara; FRONTINI, Romina; VECCHI, Rodrigo  y  BAYON, Cristina. STABLE ISOTOPES AND DIET OF HUNTERS GATHERERS OF SOUTHWEST OF BUENOS AIRES PROVINCE (ARGENTINA). Chungará (Arica) [online]. 2016, vol.48, n.3, pp.383-395.  Epub 31-Mayo-2016. ISSN 0717-7356.  http://dx.doi.org/10.4067/S0717-73562016005000020.

Results of thefirst stable isotopes analysis (δ13C and δ15N) ofarchaeological sites located in the southwest oftheprovince ofBuenos Aires (Argentina) are presented. Both the construction ofan isotopic ecology andprehistoric human diets ofthe sector are explored. The isotopic ecology indicates diverse environments in which marine animals have enriched δ13Ccol. values; while terrestrial species such as coypo, greater rhea and large-sized herbivores have the poorest values that are indistinguishable among the different taxa. Furthermore, ducks and a hairy armadillo showed intermediate values. Human isotopic values indicate a diet based on the consumption of meat. These proteins came predominantly from terrestrial animals complemented by marine resources. The local archaeological record is consistent with this information, as the main faunal resources are terrestrial species; nevertheless a scarce representation of marine fauna, mainly Otariids, is registered. In this paper we present the first isotopic values for the studied area and thus it is a preliminary contribution that must be further investigated with new samples.
