Las puntas de proyectil en "mandorla" de Inca Cueva 7: Caracterización tipológica e historia de vida (Puna de Jujuy, Argentina)

Abstract

Mandorla projectile points recovered in a ca. 4000 years BP intentional deposit of artifacts from the Inca Cueva 7 site (Puna of Jujuy, Argentina), are analyzed. They are studied in terms of their design and use alternatives, because it could be used one extreme or the other, turning the points at the foreshaft; besides these artifacts could be the result of resharpening of blades and/or shafted parts. We include a comparison between mandorla projectile points from Inca Cueva 7 site and mandorla artifacts from Camarones 14 site (Northern Chile). Several statistical tests are performed. Then, the benefits to maximize the performance of foreshaft, are discussed on the basis of the characteristics of three specimens recovered from the Argentinian site studied.
