在墨西哥金塔纳罗奥州图伦附近的水下洞穴中保存的史前人类骨骼遗骸,揭示了关于14C年代测定的相互矛盾的结果。在这里,我们使用u系列技术测定了一具石笋的年代,该石笋生长在淹没在Chan Hol洞穴中的一具人类骨骼的骨盆上。最古老的封闭系统U/Th年龄来自骨盆上方约21mm处,定义了骨盆前线终点至11311±370 y BP。然而,骨骼可能相当古老,根据洞穴稳定同位素数据,可能有13ky BP的历史。Chan Hol个体证实了中美洲晚更新世的定居,代表了美洲最古老的人类骨骼遗骸之一。
Preceramic human skeletal remains preserved in submerged caves near Tulum in the Mexican state of Quintana Roo, Mexico, reveal conflicting results regarding 14C dating. Here we use U-series techniques for dating a stalagmite overgrowing the pelvis of a human skeleton discovered in the submerged Chan Hol cave. The oldest closed system U/Th age comes from around 21 mm above the pelvis defining the terminus ante quem for the pelvis to 11311±370 y BP. However, the skeleton might be considerable older, probably as old as 13 ky BP as indicated by the speleothem stable isotope data. The Chan Hol individual confirms a late Pleistocene settling of Mesoamerica and represents one of the oldest human osteological remains in America.
