THE PROBLEM ABOUT TOOTH ATTRITION AND AGE ESTIMATION OF TWO CHILDREN FROM ZHENPIYAN NEOLITHIC SITE IN GUILIN OF CHINA

Two samples studied here were unearthed from the Zhenpiyan neolithic site in Guangxi of China. One(BT1M1) is estimated as of 23-27 years old based on tooth wear standard of modera Chinese, and is of 11 years old according to tooth eruption. Another(BT) is estimated as of 23 years old based on tooth wear standard of modern Chinese, and is of 8 years old according to tooth eruption. It shows that estimating age of a prehistoric individual based on tooth wear standard of modern Chinese would be older than based on tooth eruption by 15±5 years.
