The isotopic composition of animal tissues can be used to address dietary, physiological and environmental variation in wild and domestic animals from modern and archaeological contexts. The relationship between human groups and animal populations in the past can be studied through stable isotope analysis of zooarchaeological remains, especially when addressing human strategies involving both the hunting of wild animals and the herding of domestic ones. The use of these methods in tissues from wild animals can help us to distinguish whether particular archaeological assemblages resulted from mass kill events or accumulations of many kill episodes occurred in the past. In contrast, the use of these methods in tissues from domestic animals can help us to investigate flock composition, diet and mobility in the past. However, before these methods can be applied to resolve such questions, intra-herd variation in isotopic composition and its causes must be addressed and explored by a modern reference data set. For this purpose, we conducted a preliminary study of the intra- herd variation in d13C and d15N values measured on bone collagen from wild (V. vicugna) and domesticated (L. glama) camelids of the Dry Puna of Argentina. This work represents the first step towards the study of intra-herd variability through stable isotope analysis in wild and domesticated camelid herds in order to address hunting and herding strategies employed by human groups in the past
