La Dolina de l’Esquerda de les Alzines (Macizo del Garraf, Barcelona): Un yacimiento del Pleistoceno superior al aire libre con industria lítica paleolítica

Abstract

Dolina Esquerda de les Alzines is the only known site in Garraf massif where abundant Palaeolithic artifacts have been recovered. However, the chronological framework and technological traits cannot place the site amongst one of the Upper or Middle Palaeolithic tool groups. Its singularity is in the location, inside a dissolution doline, a rare deposit in the Middle and Upper Palaeolithic sites in Iberian Peninsula. The lithic assemblage is homogenous, 1,067 artifacts have been analyzed to determine their characteristics and the most significant feature of this assemblage is the dominance of flake-bearing core reduction methods and the manufacture of artifacts showing convergent morphologies. The recovery of some artifacts commonly found in Upper Palaeolithic assemblages should also be stressed.
