Description
Summary:In the Deseado Massif there are many stratified archaeological sites located in caves and rockshelters. The cultural sequences, proposed in the past century, include an occupational hiatus and cultural changes that were developed on the basis of large tools from archaeological sites, without debitage analysis. The aim of this paper is to review the current debate on lithic technology and human occupations of this area during the Mid-Holocene, integrating new data, as well as the latest environmental interpretations. The contribution of new information from blade and bifacial technologies is central to discussion of the models proposed by other authors. The new baseline information generated in the last decade, allow original interpretations. The evidence of coexistence between blade and bifacial technologies during the Mid-Holocene constitutes the main contribution of this paper.
