This paper is part of a larger research project, whose principal goals include contributing to the knowledge of human subsistence in Central West Argentina. Specifically, they address the use of camelids, establishing the presence of diverse morphotypes (wild and domestic) and determining economic strategies, in terms of the consumption of these animals by inhabitants of the region throughout the Holocene. Given the necessity of more precisely identifying camelid archaeological remains, various techniques have been used. The most common are: osteometry, incisor and fiber morphology, and recently, stable isotopes and aDNA. Each of these analysis has strengths and weaknesses, and for this reason, combining them may be able to improve the desired distinction. This paper presents, as an example, a combination of osteometry, multivariate statistics, isotopes, and aDNA from a single archaeological specimen, a scapula from the site ARQ-18, in a context dated to 3090 cal B.P. (3340-2870, 2 sigma), with the goal of identifying the species. The tested specimen was identified as Vicugna vicugna, as it is morphometrically similar to six modern comparative specimens. In contrast, the results of isotopes did not allow for a taxonomic discrimination, while the aDNA did so to the level of genus. Based on this, osteometry, statistical tests, and reference collections should be improved, which have already been successfully applied in various parts of the Andes. Compared to the other newer methods, osteometry has more potential to distinguish between domestic and wild camelids. It is much affordable, nondestructive, does not require excellent preservation, and generates results which can be replicated. [ABSTRACT FROM AUTHOR]
