Unlike other Gravettian contexts in Southern Iberian Peninsula, the Early Gravettian lithic assemblage from the archaeological site of Vale Boi (SW Portugal) is characterized by the absence of typical backed points, such as Gravettian and Microgravette points. Instead, backed technology is present in the unusual form of bipointed double backed bladelets. The presence of these backed tools in other Gravettian contexts is very rare, and their strong presence in the lithic assemblages from Vale Boi has no parallel in Southern Iberia, representing a novelty for the Gravettian record in the region. Given their morphology, this type of backed tool has been associated, in other industries, with perforation activities. In this paper, however, we present the results on technological, macro and micro-wear analyses showing the presence of fatigueImpact wear traces (diagnostic impact fractures and hafting traces) commonly associated to projectile tips. These data represent a novelty in lithic projectile technology from Southwestern Iberia, and may reflect improving hunting techniques related to diet diversification and intensification and/or stylistic variation among Gravettian population.
