Summary

Descripción general del contenido del recurso.

We report the first results of a shooting experiment performed with lithic point replicas of Fishtailpoints hafted as darts pursuing the aim to estimate the points’ use-lives and related size changesusing survival and risk models. A total of 555 successful shots were done, ranging from one to 146shots and from zero to four resharpenings. The obtained results suggest that Fishtail points have along use life, with a median of 15 shots and most of them withstanding between three and fourresharpenings. Survival and risk models note that point survival is significantly correlated tomaximum point width and stem neck width. This opens new questions about longevity andsurvival probability of Fishtail points, offering empirical information to evaluate huntingstrategies and comparative advantages in the use of different point technologies in theprehistory of southern Patagonia.
