Assessing Fishtail points distribution in the southern Cone

摘要

This paper discusses possible causes affecting the distribution of Fishtail points in the southern Cone. This distribution is discontinuous, with large territories without diagnostic remains and areas where sites and points are concentrated. Also, most of the sites with this type of points exhibit few specimens, with remarkable exceptions in Uruguay, the Argentinian Pampa and Patagonia and southern Chile. We present thoughts arising from long term research in the central east Tandilia ranges, in the Argentinian pampas with information relevant to this discussion.
