Abstract: The age determination of 4 individuals from Chongtang neolithic site in Chongzuo County, Guangxi were investigated by the observation of histological specimens. Age of M02, 509, S10 were estimated 32, 17, 35 years old respectively, based on the fact that in the subperiosteal parts of midshaft of femur and tibia the number of osteons and of osteon fragments increases with increasing age. And the age of S08 is 51, based on the incremental lines of the dental cementum.

Key words: Tooth age; Bone age; Chongtang Site; Neolithic age
