Abstract: The ages of 11 important palaeolithie sites in South China were determined by uranium series dating of vertebrate teeth, bones and travertines. In order to test the assumption that there is closed system in fossil bones, the 230Th, 231 Pa and/or231Pa/230Th ages for every sample were measured simultaneously. Only those ages of samples that give concordant ages by different methods are considered reliable. According to the present and our previously reported results for the palaeolithic sites in North China (Chen, Yuan and Gao, 1984) , an uranium series ehronological sequenee was given.

Key words: Uranium series dating; South China; Palaeolithic sites
