长期以来，考古学家一直对克洛维斯巨型动物的杀戮/屠杀地点进行最高级别的审查。1987年，人们在怀俄明州的匡威县发现了一头哥伦比亚猛犸（Mammuthus columbi），它与一个小型文物组合存在空间联系。然而，由于工具组合小，挖掘的有限性，以及对文物和猛犸遗骸之间联系的安全性的质疑，该遗址从未被列入北美人类杀害/被清除的巨型动物的摘要。在这里，我们提出了四个领域的新的挖掘季节在La Prele猛犸网站，确认存在相关的文化职业的基础上，地质背景，文物属性，空间分布，蛋白质残留分析，和岩屑微磨损分析的结果。这项新工作确定了一个更广泛的文化职业，包括在猛犸骨床附近存在多个离散的人工制品集群。这项研究证实了存在的第二个克洛维斯猛犸杀死/屠宰场在怀俄明州，并显示了价值，重新提出终端更新世杀死/屠宰场。
Archaeologists have long subjected Clovis megafauna kill/scavenge sites to the highest level of scrutiny. In 1987, a Columbian mammoth (Mammuthus columbi) was found in spatial association with a small artifact assemblage in Converse County, Wyoming. However, due to the small tool assemblage, limited nature of the excavations, and questions about the security of the association between the artifacts and mammoth remains, the site was never included in summaries of human-killed/scavenged megafauna in North America. Here we present the results of four field seasons of new excavations at the La Prele Mammoth site that confirm the presence of an associated cultural occupation based on geologic context, artifact attributes, spatial distributions, protein residue analysis, and lithic microwear analysis. This new work identified a more extensive cultural occupation including the presence of multiple discrete artifact clusters in close proximity to the mammoth bone bed. This study confirms the presence of a second Clovis mammoth kill/scavenge site in Wyoming and shows the value in revisiting proposed terminal Pleistocene kill/scavenge sites.
