摘要

摘要：我们报道了一项射击实验的第一个结果，该实验使用鱼尾点的石器点复制品作为飞镖，目的是使用生存和风险模型来估计这些点的使用寿命和相关的尺寸变化。总共完成了555次成功的击球，从1次到146次，从0次到4次重新击球。所获得的结果表明，鱼尾点的使用寿命很长，中位数为15次，其中大多数可以承受三到四次重新打磨。生存率和风险模型指出，点生存率与最大点宽度和茎颈宽度显著相关。这就提出了关于鱼尾点的寿命和生存概率的新问题，为评估巴塔哥尼亚南部史前时期使用不同点技术的狩猎策略和比较优势提供了经验信息。

Late Pleistocene-Early Holocene Fishtail Points from Southernmost Patagonia (South America): An Estimation of Use-Life Using Experimental Data and Survival Curve Models

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

期刊介绍： PaleoAmerica disseminates new research results and ideas about early human dispersal and migrations, with a particular focus on the Americas. It fosters an interdisciplinary dialog between archaeologists, geneticists and other scientists investigating the dispersal of modern humans during the late Pleistocene. The journal has three goals: First and foremost, the journal is a vehicle for the presentation of new research results. Second, it includes editorials on special topics written by leaders in the field. Third, the journal solicits essays covering current debates in the field, the state of research in relevant disciplines, and summaries of new research findings in a particular region, for example Beringia, the Eastern Seaboard or the Southern Cone of South America. Although the journal’s focus is the peopling of the Americas, editorials and research essays also highlight the investigation of early human colonization of empty lands in other areas of the world. As techniques are developing so rapidly, work in other regions can be very relevant to the Americas, so the journal will publish research relating to other regions which has relevance to research on the Americas.
