秘鲁劳里科察湖附近的洞穴于20世纪50年代末至60年代中期被挖掘，此后影响了南美洲早期人类的解释。在这篇论文发表之前，用于解释这种材料的年龄的数据并不是基于人类骨骼本身，而是由沉积物、植物遗骸和动物骨骼等伴生材料产生的。20世纪60年代的放射性碳测年通常不适用于人体骨骼，因为当时的前处理方法没有现在那么精细，而且采用传统技术，需要使用相当多的材料。AMS技术的发展需要更少的分析和胶原蛋白提取样品的材料，这意味着现在可以对人体骨骼进行放射性碳测年，这是一种可靠的方法。作为分析Lauricocha骨骼DNA以阐明秘鲁迁徙模式的更广泛项目的一部分，我们对11具骨骼中的4具进行了放射性碳测年。本文报道了这一测年分析的结果。结果表明，这些骨骼比以前从不同材料上确定的放射性碳数据解释的骨骼更年轻。然而，这并不意味着旧的分析是错误的，我们根据之前的工作审查了我们的发现，为该网站制作了新的年表。
The caves near Lake Lauricocha, Peru, were excavated between the late 1950s and mid-1960s and have since influenced the interpretation of early man in South America. Prior to the publication of this paper, the data used to interpret the age of this material was not based upon the human skeletons themselves, but were rather produced from the accompanying material, such as sediment, plant remains and animal bone. Radiocarbon dating in the 1960s was often not applied to human bones, as pre-treatment methods at that time were not as refined as at present and with conventional techniques, quite a lot of material had to be used. The development of AMS techniques requires much less material for analysis and sample preparation through collagen extraction means that radiocarbon dating of human bones is now possible and is a reliable method. As part of a wider project to analyse the DNA of the Lauricocha skeletons in order to elucidate migration patterns in Peru, we sampled 4 of the 11 skeletons for radiocarbon dating. This paper reports the results of this dating analysis.The results indicate that the skeletons are younger than interpreted from previously determined radiocarbon data on different material. However, this does not mean that the older analyses are wrong, and we review our findings in the light of this previous work to produce a new chronology for the site.
