Forensic anthropologists can identify bones and fragments of bones, initially determining whether they are human or animal. Explains that forensic anthropology is the examination of human remains for law enforcement agencies to determine the identity and cause of death in unidentified bones. The site is secure. Forensic anthropologists may contribute to trauma analysis through assessment of: (1) the timing of the trauma (i.e., antemortem, postmortem or perimortem), and (2) the mechanism that produced the trauma (i.e., projectile, blunt, sharp, thermal). What conclusion can he MOST likely make about this person's age at their time of death? Male greater sciatic notch (left) and female (right) greater sciatic notch.

A forensic anthropologist is a scientist trained to identify human remains and interpret evidence to determine cause of death. The sorts of treatments that would be used today (traction and screws), were not options at the time.
