Resumen:
The subsistence of hunter-gatherers in the Pampas region for the last 12,500 years BP has been defined almost exclusively on the zooarchaeological record. However, for the construction of the trends in the diet, some areas of the region did not provide relevant archaeofaunal information. The main goals of this presentation are to highlight temporal variation in the exploitation of faunal resources and to propose the first subsistence model in shallow lake environments in the Central Pampean Dunefields during the Holocene. We report and integrate novel quantitative faunal information and index of diversity and abundance from four stratified archaeological sites (La Susana 1, Laguna de los Pampas, Cabeza de Buey 2, and Huencú Nazar). The chronological range of these archaeological contexts include the early Middle Holocene (7400-6800 years BP), the late Middle Holocene (5900-4100 years BP) and the Late Holocene (3000-500 years BP). The results indicate an outstanding relevance of the larger artiodactyl (Lama guanicoe) and a breadth of diet that varied over time, which is linked with the site functionality and the dynamics of this lake environment. During the beginning of the Middle Holocene the highest values of diversity suggest the exploitation of a wide variety of species. During the second part of the Middle Holocene and in the Late Holocene hunter-gatherers concentrated on the exploitation of the Lama guanicoe, with a secondary importance of the smaller species. In the last part of the Late Holocene the importance of Lama guanicoe decreased slightly. These trends in faunal exploitation show certain similarities with other areas of the Pampas region.
