Abstract
In forensic anthropology and beyond, age estimation is a crucial element of the biological profile. In 2019, Winburn and Stock discovered that age was the variable most effective at predicting the presence or absence of osteoarthritis (OA) in any appendicular joint and the TMJ. This study validated Winburn and Stock (2019) on a sample of 298 individuals from Eastern Tennessee, and expanded the original study by testing its accuracy on a more diverse sample of individuals. This served to test whether embodied inequality from lived experiences may preclude the ability of the OA presence/absence method to estimate age at death. The results demonstrated both that the original methodology was validated, and that the approach was accurate at estimating the age of death of BIPOC individuals. Further, the study revealed that the hip and the shoulder were highly consistent and reliable and are recommended for use as the strongest indicators of age at death, while the TMJ and ankle performed poorly and should not be used for age estimation.
