First direct dating of a presumed Pleistocene hominid from China: AMS radiocarbon age of a femur from the Ordos Plateau 总被引:1,自引:0,他引:1
Human remains from the Xarusgol Valley, Ordos Plateau, northwestern China, have been considered to date to the Late Pleistocene. In order to ascertain their true age, direct AMS (14)C dating of a femur collected in the early 1920s was conducted. The results demonstrate that the femur is very young, with one sample of 'post-bomb' age and the other sample c. 200 years old. This first direct dating of a Chinese fossil hominid underscores the need to apply the same methodology to other Chinese modern human fossils currently believed to be of Pleistocene age. 相似文献

洛南盆地旧石器遗址地层划分及年代研究 总被引:8,自引:5,他引:8
1995-1999年,在秦岭东部山区的洛南盆地发现50处旷野类型旧石器特点,并对花石浪龙牙洞洞穴遗址进行发掘,获得大量旧石器材料。本文对洛南盆地旧石器遗址地层进行了划分及对比研究,并进行了热释光(TL)测年数据分析。从地层对比及所测5个样品结果判断,龙牙洞及二级阶地地层年代属中更新世中晚期(O2^2-5),与北京直立人洞穴堆积层相当,绝对年代距今25-50万年左右,属旧石器时代早期。 相似文献
