description	Ongoing research performed in the central part of Uruguay added new Paleo-Southamerican finds from the Negro River basin. A number of lithic exemplars were analyzed to determine their technology and function. The examined artifacts provided a new perspective on Fisthail points. Microwear analysis showed that there is a difference in the location of microscopic polishing between the blade and stem in the examined points. Polishing in the stem?s border might be attributed to leather or a similar substance, probably the leather cord or sinew used to bind the points in the foreshaft. The surface of the stem shows a coarse micro-topography and has patches of black residues. The coarse micro-topography suggests the use of an adhesive substance covering the whole stem, while the black patches are probably the residue used to glue the points in the foreshafts. Most remarkable is the discovery of the use of edge-to-edge and overshot flaking for bifacial reduction, technical features shared with Paleoindian fishtailed points from North and Central America.
