1 CHE 113 1 FORENSIC ANTHROPOLOGY A Very Brief Overview CHE 113 Thanks to help from Prof. Ann Bunch, SUNY Oswego

2 CHE 113 2 Forensic Anthropology Brief Overview Defined as “the field of study that deals with the analysis of human skeletal remains resulting from unexplained deaths.” Often done in a legal context An applied science Five subdisciplines: 1. Biological, or physical anthropology 2. Archaeology 3. Cultural anthropology 4. Linguistics 5. Applied anthropology

3 CHE 113 3 Forensic Anthropology Goal: Biological Profile Includes: 1. General Description 2. Sex of decedent 3. Age of decedent 4. Ancestry of decedent 5. Stature of decedent 6. Assessment of trauma (ante-, peri-, post mortem) 7. Pathologies noted

4 CHE 113 4 Osteology: study of skeletal remains Each bone studied INDIVIDUALLY 206 Skeletal Bones (total)

5 CHE 113 5 Osteology: study of skeletal remains Each bone studied INDIVIDUALLY

6 CHE 113 6 Osteology Human bone –vs- Animal bone Macroscopic differences Radiology Observation Measurement Microscopic differences

7 CHE 113 7 Osteology

8 CHE 113 8 Osteology

9 CHE 113 9 Macroscopic differences Baboon femurHuman femur

10 CHE 113 10 Microscopic differences Spongy bone human mouse

11 CHE 113 11 Osteology Radiographs

12 CHE 113 12 Information from skeletal remains Sex of decedent Hip boneFemur Skull

13 CHE 113 13 Information from skeletal remains Sex of decedent http://medlib.med.utah.edu/kw/osteo/forensics/sasta.html

14 CHE 113 14 Information from skeletal remains Sex of decedent MALE OR FEMALE SKELETON? (a) IS FEMALE and (b) IS MALE Handout

15 CHE 113 15 Information from skeletal remains Sex of decedent MALE OR FEMALE SKELETON? (a) IS FEMALE and (b) IS MALE Male Female

16 CHE 113 16 Information from skeletal remains Sex of decedent http://medlib.med.utah.edu/kw/osteo/forensics/sasta.html

17 CHE 113 17 What can we learn from skeletons? Age at Death Hip bone most useful for adults Teeth: Erupted or Not? Estimate given as a range (30 – 35 yrs old) Epiphyses: fused or unfused? Pubic symphysis Auricular surface

18 CHE 113 18 Age at Death Long Bone Development

19 CHE 113 19 Age at Death http://medlib.med.utah.edu/kw/osteo/forensics/sasta.html

20 CHE 113 20 Age at Death http://medlib.med.utah.edu/kw/osteo/forensics/sasta.html

21 CHE 113 21 Osteology Teeth also studied Deciduous –vs- Permanent

22 CHE 113 22 Age at Death http://medlib.med.utah.edu/kw/osteo/forensics/sasta.html

23 CHE 113 23 Epiphyses - A part of bone separated from the main body of the bone by a layer of cartilage and subsequently uniting with the bone through further ossification Unfused = juvenile Fused = adult

24 CHE 113 24 Spine

25 CHE 113 25 More info from skeletal remains ANCESTRY of decedent Difficult determination to make Facial bones most important Nasal aperture Teeth Interorbital space Mandible

26 CHE 113 26 Stature estimate Measure long bone(s) available Plug in value to formula Range established for stature of decedent 5’ 2” – 5’ 5”

27 CHE 113 27 Other information TRAUMA and PATHOLOGIES Ante- mortem Post-mortem Peri-mortem Gunshot

28 CHE 113 28 Trauma

29 CHE 113 29 Individual Identification Person identified when it was found that the amalgam used in her dental restorations was of a type found only in specific areas on the Eastern Coast of the United States. Habitual activity can wear away the protective, cartilagenous lining which reduces friction in joints. The humerus in this photograph were in contact for many years prior to this individual's death. The surfaces are smooth and shiny, indicating that the joint capsule and cartilage had worn away, allowing bone on bone contact in the cavity. http://medlib.med.utah.edu/kw/osteo/forensics/sasta.html

30 CHE 113 30 Individual Identification Dental implants, braces, and other types of dental work are often recovered with a body and are extremely useful in identification because they are so unique to the individual and are well detailed in antemortem radiographs and medical records. Healed fracture on the sternal end of a midthoracic rib. The area within the red brackets is the site of injury. Note the more porous appearance of the bone in this area - this is woven bone. http://medlib.med.utah.edu/kw/osteo/forensics/sasta.html
