Found in 1968, the archaeological site of Anzick, Montana, contains the only known Clovis burial. Here, the partial remains of a male infant, Anzick-1, were found in association with a Clovis assemblage of over 100 lithic and osseous artifacts-all red-stained with ochre. The incomplete, unstained cranium of an unassociated, geologically younger individual, Anzick-2, was also recovered. Previous chronometric work has shown an age difference between Anzick-1 and the Clovis assemblage (represented by dates from two antler rod samples). This discrepancy has led to much speculation, with some discounting Anzick-1 as Clovis. To resolve this issue, we present the results of a comprehensive radiocarbon dating program that utilized different pretreatment methods on osseous material from the site. Through this comparative approach, we obtained a robust chronometric dataset that suggests that Anzick-1 is temporally coeval with the dated antler rods. This implies that the individual is indeed temporally associated with the Clovis assemblage.
1968 年发现的蒙大拿州安兹克考古遗址中包含了唯一已知的克洛维斯埋葬地。在这里，发现了一名男性婴儿安兹克-1 的部分遗骸，与超过 100 件石制和骨制人工制品的克洛维斯组合在一起——所有这些都用赭石染成红色。还发现了一个未关联的、地质年龄较小的个体安兹克-2 的不完全、未染色的颅骨。之前的年代测定工作表明，安兹克-1 和克洛维斯组合（由两个鹿角棒样本的日期代表）之间存在年龄差异。这种差异引起了很多猜测，有些人认为安兹克-1 不是克洛维斯人。为了解决这个问题，我们展示了一个综合的放射性碳测年计划的结果，该计划利用了来自该遗址的骨材料的不同预处理方法。通过这种比较方法，我们获得了一个强大的年代数据集，表明安兹克-1 与有日期的鹿角棒在时间上是同时代的。这意味着这个人确实与克洛维斯组合在时间上有关联。
