Chenque I site is a prehistoric cemetery located in Lihué Calel National Park (La Pampa province) in the Western Pampean region of Argentina. Hunter-gatherer societies made use of this site during the Final Late Holocene for at least 700 years (1030-370 BP). Currently 41 burial structures have been excavated, and more than 150 individuals have been recovered. There is great variability in mortuary patterns at the site (simple, multiple, primary, secondary burials, and also a variant not previously observed in the region).The life-ways of this population have been investigated through the evaluation of several biological and cultural factors. Several pathological conditions have also been identified in this cemetery. Burial no. 12 contains a skeleton of an adult male that shows multiple pathological lesions, compatible with a neoplastic disease. These lesions have been analysed using several methodological strategies: macroscopic, radiological and microscopic. This is the first time that this kind of disease has been identified from a prehistoric burial in Argentina.In this paper the location and characteristics of the lesions are evaluated, and the different neoplastic diseases that could have produced them are discussed. Since the people buried in this cemetery belonged to highly mobile societies, a key issue is to infer the consequences that this disease would have had on the dynamics of the group in which this person lived, because of the gradual deterioration of his health and physical strength.

Different lines of archaeological research have been developed in order to increase our knowledge of the history of the hunter-gatherer societies that inhabited the western Pampas of central Argentina, South America, during the Late Holocene. Recently, stable isotope data from human remains have been included. This paper presents the first group of d C and d15 N results obtained for this region. On this basis we identify spatial and chronological patterns that may have interesting implications at the levels of spatial organisation and temporal changes. Then, we evaluate the existence of correlations with other lines of archaeological evidence. Finally, we propose an agenda for future work including the generation of a robust regional isotopic ecology that will provide the context for the development of specific dietary reconstructions.
