El conjunto de fauna menor del sitio La Modesta: un aporte al estudio de la subsistencia durante el Holoceno medio en la transición pampeano-patagónica oriental (Buenos Aires, Argentina)

Abstract

espanolEn este trabajo se exponen los resultados obtenidos de los analisis realizados sobre los restos de fauna menor ( EnglishThis work presents the results from the analysis of the small-sized vertebrate remains recovered from the surface and stratigraphic contexts of La Modesta site (eastern Pampa-Patagonia transition, Buenos Aires province). This site is located in an area of deflated dunes, close to a paleochannel of the Colorado River, and 60 km away from the Atlantic coast. Radiocarbon dates place the human occupations in the Middle Holocene (ca. 5900-5600 years BP). Our analyses show that the faunal assemblage is the result of complex taphonomic histories, and that the presence of the identified species is a consequence of different causes. Results indicate that, in addition to perch, other species, such as Myocastor coypus, medium-sized birds, and possibly armadillos, would have contributed to the diet of the human populations. This information, together with the data already available from the site (analysis of the larger-sized species, and stable isotopes), represent the first approaches to hunter-gatherers subsistence during a period that lacked such information in the study area.
