Foot bones allow researchers to determine sex of skeletal remains

Law enforcement officials who are tasked with identifying a body based on partial skeletal remains have a new tool at their disposal. A new paper from North Carolina State University researchers details how to determine the biological sex of skeletal remains based solely on measurements of the seven tarsal bones in the feet.

"Tarsals are fairly dense bones, and can be more durable than other bones – such as the pelvis – that are used to determine biological sex," says Dr. Troy Case, an associate professor of anthropology at NC State and co-author of a paper describing the research. "Also, the tarsal bones are often enclosed in shoes, which further protects them from damage. That's particularly useful in a forensic context." The tarsals are the seven bones that make up the ankle, heel and rear part of the arch in a human foot. Eurekalert!
