A Sino-France research team reported preliminary dating results of seven herbivorous fossil teeth from different archaeological layers of the lowest geological unit (C III) of Longgupo Cave site, Wushan County, Chongqing, China. The obtained US-ESR results published in the July 2012 issue of the Quaternary Geochronology, show that the age of six teeth are basically consistent, between 1.4 and 1.8 million years ago. This result confirms the antiquity of Longgupo site which could have an impact on the chronology of hominid presence in southern China, helping better understand the human migration and settlement in East Asia.
