Title: FORENSIC ANTHROPOLOGY


1
FORENSIC ANTHROPOLOGY
WHAT IS IT?
WHAT DOES A FORENSIC ANTHROPOLOGIST DO?
HOW DOES ONE BECOME A FORENSIC ANTHROPOLOGIST?
2
Forensic Anthropology
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
3
ANTHROPOLOGY
Study of humans holistic view
5 subdisciplines
1. Biological, or physical anthropology
2. Archaeology
3. Cultural anthropology
4. Linguistics
5. Applied anthropology

Microscopic differences
                                                  
                                                  
                     This is a microphoto is
human bone use to id human remains from other
mammals.  The round features are secondary
osteons photographed using polarizing light.

Epiphyses
An epiphysis is a region of bone growth found at
the ends of bone shafts. These regions are not
fused to the rest of the bone shaft during the
ages of grwoth. Once growth has ceased, they
fuse with the shaft. Usually after the age of 17.
Fused adult

Unfused epiphyseal plate juvenile (under age 17)

Determining Cause of Death or Other Injuries

Other info
TRAUMA and PATHOLOGIES
Antemortem before death
Postmortem after death
Perimortem at death or around time of death
31
Perimortem Injuries
Iron age period male with perimortem sword wound
to the skull. 
Injury occurred at or around the time of death
and may have even caused the death
32
Antemortem Injuries
Injuries that occurred during the decedent's
lifetime they appear healed.

Rediscovering Pompeiani
  • Giuseppe Fiorelli took charge of the excavations
    in 1860. During early excavations of the site,
    occasional voids in the ash layer had been found
    that contained human remains.
  • It was Fiorelli who realized these were spaces
    left by the decomposed bodies and so devised the
    technique of injecting plaster into them to
    perfectly recreate the forms of Vesuvius's
    victims.
  • What resulted were highly accurate and eerie
    forms of the doomed Pompeiani who failed to
    escape, in their last moment of life, with the
    expression of terror often quite clearly visible.
  • This technique is still in use today, with resin
    now used instead of plaster because it is more
    durable.
