Question
Determining age at death for sub-adults is achieved by looking at the
degree of epiphyseal fusion in several bones from the same
individual. Forensic Anthropologists create a chart to illustrate the
overlap between the ages at which various fusions occur:
Example: the proximal end of the humerus fuses between the ages
of 14-23 years old. The distal end of the humerus fuses between the
ages of 11-18 years old. If the recovered human remains humerus
has an proximal end that is almost but not quite fused and a distal end
that is fused solid, then we can estimate the age at death as between
14-18 years old.
