Osteology, the study of human bones, along with other investigative modes used for define trauma and time of death are important in the fields of archeology as well. The author high- lights the fact that the study of human remains in archaeological contexts allows archaeologists to better identify significant factors present on the remains that could aid in their understanding of a site or culture. Introduction lives and how they died based of characteris- tics identified on the remains. Like forensic In forensic anthropology it is important for investigators, they attempt to identify the sex, scientists to be able to distinguish between age at death, ethnicity, and stature of the indi- trauma that occurs prior to death, at death, and vidual.
