3 What can bones tell us? Human or nonhuman Human or nonhuman Age Age Gender Gender Stature Stature History of trauma or disease History of trauma or disease Evidence for cause and manner of death Evidence for cause and manner of death Handedness & type of occupation Handedness & type of occupation Racial determination not reliable Racial determination not reliable

4 Intact vs. disarticulated (In which case is identification easier?)

5 Intact is easier but not likely to be found by a forensic anthropologist.

6 Excavated remains Typical skeleton found at a crime scene.

7 Posterior view Scapulae not always noticed in front view

8 Do you see the scapulae here?

16 Traditional facial reconstruction Forensic Anthropologist can reconstruct a face from skeletal remains.

17 Computer-aided facial reconstruction Computer programs can also reconstruct facial features from a skull.

18 Bones of the skull 1. Parietal Bone 2. Coronal Suture 3. Frontal Bone 4. Nasal Bone 5. Vomer 6. Lacrimal Bone 7. Orbital Part of Ethmoid 8. Zygomatic Bone 9. Maxilla 10. Body of Mandible 11. Ramus of Mandible 12. Coronoid Process 13. Mandibular Condyle 14. Mental Foramen 15. Styloid Process 16. External Acoustic Meatus 17. Mastoid Process 18. Zygomatic Process 19. Temporal Bone 20. Greater Wing of Sphenoid 21. Inferior Temporal Line 22. Superior Temporal Line 23. Squamosal Suture 24. Lambdoidal Suture 25. Occipital Bone

19 Bones of the Human You should know the names of the bones of the human skeleton.

20 Bones of the Human male vs. female The female pelvis has a larger opening than the male-for child bearing.

21 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 “U.”

22 Bones of the Human male vs. female The slope of the forehead of the female is different than the male. The female has a “rounded” shape and the male is more of a slope.

23 Bones of the Human male vs. female

26 Bones of the Human Race Determination

27 Nasal spine: Prominent Progathism: straight Orbital openings: round

28 Bones of the Human Race Determination

30 Bones of the Human Age Determination Occupational stress wears bones at joints

31 Bones of the Human Age Determination Surgeries or healed wounds aid in identification

32 Bones of the Human Age Determination Teeth can help determine age of a skeleton.

33 Bones of the Human Other Information Evidence of trauma (here GSW to the head)

34 Bones of the Human Other Information Evidence of post mortem trauma (here the head of the femur was chewed off by a carnivore)

35 Bones of the Human Use your knowledge of Forensic Anthropology to tell something about each of the following slides.
