Human bone sex identification is based on the characteristics of the whole body bones, especially the pelvis, the preservation of the skull, mandible, hip, sacrum and upper and lower extremity bone for comprehensive identification results, but some tomography because of incomplete, according to only Of the material to be identified (Table 1). Age identification is mainly based on the degree of tooth abrasion, we first refer to modern standards for estimating the age of the molar wear rate, get the estimated age of each molars preserved, and then calculate the estimated age of each individual molars, calculate a average
