THE SECRETS IN THE SKULL
FORENSIC ANTHROPOLOGY
• Bones are often only remainders after a body decomposes• Forensic
anthropologists use bones to solve crimes• Can determine age,
race, sex, general health, and cause of death using bones
THE SKULL•Made up of 22 Bones
• Two regions• Cranium: • skull without the jaw
• Mandible: • lower jaw
THE BONES THAT MAKE UP THE SKULL
TEETH• Four different types• Incisors• Canines• Premolars• Molars
• Also used to identify a victim • X-rays/dental records
SEX• Men• More prominent• Slanted frontal bone• Pronounced brow
ridge• Square chin• Women• More delicate
features/less prominent
• Rounded frontal bone• Smooth brow ridge• Rounded chin
MALE VS FEMALE
AGE• Sutures used to determine
age• Suture: the place where two
major bones join together• Bones not fused at birth• different bones fuse at
different times• Skull becomes smoother
over time• Younger person has more
prominent sutures than older person
RACE• Anthropologists take measurements,
compare them to database called Fordisc• Thickness, structure of bones• Also, breadth of nasal aperture, nasal root
height, head shape, suture appearance, distance between occipitals, prominence of zygomatics, jaw thickness, brow ridge size, slope of frontal bone, etc.
CAUSE OF DEATH• Antemortem: before death• Will show signs of healing• Perimortem: around the time of death• Used to determine cause of death• Different forces cause different injuries• Postmortem: after death• Caused by weather or scavengers
Blunt force traumaGunshot wound
