Osteology
Osteology
The study of bones, often used in forensic anthropology to determine age, sex, and ancestry of skeletal remains.
Odontology
Odontology
The study of teeth. It's a key tool in forensic anthropology for estimating age and identifying individuals.
Taphonomy
Taphonomy
The study of the processes that affect the decomposition of remains after death. It's vital for understanding how and why bones are found in a specific state.

Study Notes
Forensic Anthropology
- Forensic anthropology applies anthropological theory and methods to forensic problems.
- Crucial for skeletal remains, determining if they are human and if they contain forensic importance.
- Osteology (study of bones) and odontology (study of teeth) knowledge is essential.
- Adult skeletons have 205 bones; children/infants can have up to 405 due to ossification.
- Post-mortem alterations need to be differentiated from pre-mortem changes.
- Forensic anthropologists are often called to assist in body recovery and taphonomic contexts to help interpret post-mortem processes.
Biological Profile
- Assessing remains to estimate characteristics like sex, age, and ancestry.
- Height estimation uses total body length, long bone lengths, or extrapolation.
- Skeletal development helps narrow age ranges.
- Females generally develop slightly earlier than males.
Teeth
- Humans have deciduous and permanent dentitions.
- Deciduous = two incisors, two premolars, one canine, and three molars per side
- Permanent dentitions = varies in number per side.
Determining Sex
- Female skulls feature a shallower sciatic notch and a U-shaped subpubic angle.
- Specialized measurements are vital for detailed analysis.
Determining Age
- Suture marks (ossification) allow age estimations.
- In adults, bones fuse as age progresses; in children, dental development is crucial for age estimations.
Taphonomic Context
- Understanding the environment where the remains are found, including factors like the surrounding soil and vegetation; crucial in obtaining accurate information on post-morten processes.
Determining Ancestry
- Skull formations, nasal openings, and jawline features help determine ancestry.
Skeletal Trauma Analysis
- Analyzing skeletal remains to determine signs of trauma, whether the trauma occurred before, during, or after death.
- Types of trauma include broken bones, fractures, defensive wounds, etc
- Environmental, blunt, or gunshot wound patterns can help in providing more accurate information.
Importance of Forensic Anthropologoy
- Used for identifying human or non-human remains and providing information about the victim.
- Analyzing bones can determine age, sex, ancestry, and cause of injuries helping to identify and understand the victim's life.
Bone Analysis
- Osteoporosis, loss of bone density, can be seen in examined remains
- Presence of carbon and strontium can determine location and residence from the bones used in analysis
- Different areas have different levels of strontium content
