Fishtail Points, Technology and Microwear Analysis from the Negro River Basin, Uruguay

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 sh...

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.
