摘要：
The fossils of Chaoxian hominin, widely accepted as representing archaic Homo sapiens in eastern China, were recovered from the middle or slightly higher levels of Layer 2 deposits of a collapsed cave at Yinshan, Anhui Province. Results of mass spectrometric U-series dating of intercalated speleothem calcites are presented. Based mainly on four broadly coeval calcite samples, the hominin fossils should be bracketed in the range of 310-360 ka or somewhat older. These ages are much older than the previous estimate at 160-200 ka based on the U-series dating of fossil teeth and bones, and may be cited as supporting evidence for an earlier H. erecrus-archaic H. sapiens interface in China.
