Análisis de microhuellas de uso mediante Microscopio Electrónico de Barrido (MEB) de artefactos óseos de un sitio Arcaico tardío del valle de Mauro (Región de Coquimbo, Chile): Aportes para una reconstrucción contextual

摘要

This paper presents the results of Scanning Electron Microscope (SEM) analysisperformed on seven bone tools from MAU085, a Late Archaic site in the semiarid northof Chile (31º 57` S-71º 01`O, IV Region). The main objective of this analysis was todetermine the function of a set of bone tools and their relation with the morphologicalvariability identified. Given prior hypothesis linking the functionality of these bonetools to flaking and resharpening of projectile points and cutting artifacts, we soughtcomplementary information in both artefactual and ecofactuals evidence, specificallythe lithic remains. Analysis by Scanning Electron Microscope shows that the bonetools studied were used in lithic as well as soft contact materials such as leather/skinand textile fibers, thus expanding the use of artefacts traditionally considered boneretouchers.
