Pierced antlers in the Southern Cone: Late Holocene hunter-gatherer groups of the low Paraná wetland.

Pierced antlers, traditionally known as bâtons de commandement, are commonly found in many Upper Palaeolithic and Mesolithic sites in Europe. Despite their original association to symbolic uses, their function is in constant debate, having as many hypotheses as contexts of finding. Predominance of symbolic use was replaced by the emphasis of antler mechanical properties chosen to perform this type of artefact. In America, pierced antlers are practically absent, however, a large number of antlers with short branches and a central perforation were found in the Low Paraná wetland. They were recovered from hunter-gatherer sites dated in the Late Holocene. In this paper, we analyse their chronological and spatial distribution, the material association and the morphometrical and physical properties of the assemblages to discuss the functional significance of these items in the local contexts. Antlers with and without perforation are considered. As a result, we note that the assemblage under analysis is morphologically different from the European's ones with symmetrical branches, despite the same material properties being maintained in the selection of deer antler as raw material. In our case, antlers without perforation are interpreted as discarded from the manufacturing processes that involve other types of tools besides there is a different proposal for a near area as the República Oriental del Uruguay. Pierced antlers show fractures and use-wear patterns like those described in the international literature. Even if no functional identification can be confirmed, high stress and domestic activity can be proposed. [ABSTRACT FROM AUTHOR]
