Different kinds of archaeological analyses have been developed in order to increase the knowledge about the history of the hunter-gatherer human societies that inhabited the western Pampas of central Argentina, South America, during the last Late Holocene. Recently, stable isotope data from human remains have been included in these studies. This paper presents the first group of ä13C and ä15N results obtained for this region. On this basis we identify spatial and chronological patterns that may have interesting implications at the levels of spatial organization and temporal changes. Then, we evaluate the existence of correlations with other lines of archaeological evidence. Finally, we propose an agenda for future work that includes the generation of a robust regional isotopic ecology that will provide the context for the development of specific dietary reconstructions.
