| Sumario: | Osteometry, in addition to other statistical approaches, is a valid technique for the interspecific differentiation of South American camelids. While the limited availability of comparative metric information, which is key for this analysis, is frequently mentioned as an obstacle. However, when compared to alternative cutting-edge methods (e.g., aDNA), which are less readily available, more time-consuming and expensive, osteometry deserves the research community’s efforts to increase the availability of comparative data. Here we present raw osteometric data taken from an emblematic specimen of Lama guanicoe cacsilencis, which has been the subject of numerous studies. These are relevant data that can be harnessed by osteometry, simply and quickly, and applied to the analysis of postcranial bones from camelids in the south-central Andes. In addition, we present a synthesis of the investigations and interpretations that were generated from the study of this specimen. We discuss nineteenth-century naturalists’ practices of obtaining and exchanging specimens and the current management of the biological collections generated by these pioneers. By applying this type of quantitative studies to expand the comparative database, and by making raw metric data available, more reliable interpretations will be achieved, considering the variability of current and potentially present camelid species and morphotypes in archaeological contexts. |
