This paper focuses in the morphometric analyses of Lama guanicoe remains recovered from the hunter-gatherer archaeological site Alero Deodoro Roca (ADR), located at Sierras Pampeanas Australes region (Córdoba Argentina), an area that has little information on the body-size variability of these artiodactyls. Because of the sparse osteometric data in the region, we focused on determining inter-intraspecific differentiation of wild camelids through corroborated osteometric techniques and multivariate statistical analyses of proximal phalanges. Our results showed a clear interspecific differentiation between modern vicuñas and archaeological specimens. We could also distinguish at least 3 guanaco size groups (small, medium and large) with the archaeological remains from the late Holocene (3000-3600 BP) of the site, presenting medium size characteristics. Finally this paper aims at establishing a first approach in the characterization of guanaco body size in the mountainous region of Córdoba.
