Abstract
A skullcap found in the Salkhit Valley in northeast Mongolia is, to our knowledge, the only Pleistocene hominin fossil found in the country. It was initially described as an individual with possible archaic affinities, but its ancestry has been debated since the discovery. Here, we determine the age of the Salkhit skull by compound-specific radiocarbon dating of hydroxyproline to 34,950–33,900 Cal. BP (at 95% probability), placing the Salkhit individual in the Early Upper Paleolithic period. We reconstruct the complete mitochondrial genome (mtDNA) of the specimen. It falls within a group of modern human mtDNAs (haplogroup N) that is widespread in Eurasia today. The results now place the specimen into its proper chronometric and biological context and allow us to begin integrating it with other evidence for the human occupation of this region during the Paleolithic, as well as wider Pleistocene sequences across Eurasia.

个Salkhit头盖骨是在蒙古东方省一个采矿场发现的,不是正常考古发掘发现的。因此无法通过地层来测年,只有对骨骼材料本身进行测年。发掘之后,遗骨保存在蒙古国历史与考古研究所,由法国国家自然博物馆的人进行了体质方面的研究,后送往马普所进行古DNA测试。测年是在牛津大学做的。
