Los Dos Amigos (LDA) archaeological locality is distinguished by the presence of a particular geological formation, two islan hills, called Amigo Oeste (AW) an Amigo Este (AE), related by afloor or open area and a gully (LDA 5). The site called Amigo West (AW) es of great importance in the region. In this hill was found a lithic assemblage composed of more than one hundred fishtail points (FTP), vifaces, knives and marginally retouched tools, and a large numbers of others artifacts that correspond to the sequences of manufacturing, ractivation, recycling and replacement of the FTP. This papers presents a techno-morphological characterization of the FTP an other bifacial artifacts associated, based on the description of its formal attributes.
