Evidence for cause and manner of death
Handedness & type of occupation
Racial determination not reliable
Intact vs. disarticulated
(In which case is identification easier?)
Intact vs. disarticulated
(In which case is identification easier?)
Intact is easier but not
likely to be found by a
forensic anthropologist.
Excavated remains
Typical skeleton
found at a crime
scene.

Traditional facial
reconstruction
Forensic Anthropologist can reconstruct a
face from skeletal remains.
Computer-aided facial
reconstruction
Computer
programs can
also reconstruct
facial features
from a skull.

Bones of the Human
You should know the
names of the bones of the
human skeleton.
Bones of the Human
male vs. female
The female pelvis has a larger opening
than the male-for child bearing.
Bones of the Human
male vs. female
The male pelvis is
“cup-like and the
female pelvis is like a
“dishpan.”
Also, the male pubic
arch is like a “V” and
the female is like a

Surgeries or healed wounds
aid in identification

Teeth can help determine age
of a skeleton.
