Abstract: A carved antler of Late Palaeolithic collected from Xinglong County,H ebeiProvince,was measured by accelerator mass spectrometry (AMS) radiocarbon dating. An age of 13 4451 ±280 BP was obtained.
Samples from Shiyu and Ximiao sites were also determined. They gave the ages of 33 155± 645 BP and--9 000 BP respectively. These values are concordant with those dated by beta counting method.
A rchaeological significance based on these results is discussed.

Key words: AMS radiocarbon dating; Xinglong; Shiyu; Ximiao
