ANATOMY

Detailed explanation-1: -The adult human pelvis is useful to estimate age because it contains three age indicators-the pubic symphysis, auricular surface, and acetabulum.

Detailed explanation-2: -Methods for aging adult skeletal remains typically use measurements from two bones in the pelvis: the ilium and the sacrum. [1] Since it is common for forensic anthropologists to receive incomplete skeletons that may not include the pelvis, they often rely on past experience to estimate age at death.

Detailed explanation-3: -Bone age is calculated by comparing the left wrist radiographs of the subject with the nearest matching reference radiographs provided in the atlas which are standard for different ages provided in the atlas. This method is simpler and faster than other radiograph based methods.
