δ13C and δ15N variability in modern guanaco (Lama guanicoe) assemblages in southern Patagonia: Implications for zooarchaeological studies

We study the isotopic variability of modern social groups of guanacos (Lama guanicoe) and discuss the implications of these results for the analysis of archaeofaunas from archaeological sites of Patagonia. The aim of this work is to evaluate whether the study of the isotope composition of carbon and...

The aim of this work is to evaluate whether the study of the isotope composition of carbon and nitrogen from collagen (δ13C and δ15N) is a methodology that allows the discussion of hunting strategies - individual versus mass - carried out by human populations in this particular case of the guanaco from southern Patagonia.

In relation to the main purpose of this research, measurements of variability from modern assemblages and the attritional groups have been compared. The three assemblages with lower variability are modern ones. However, the two remaining modern assemblages record a variability higher than or equal to the attritional groups.
