Test of revised method of age estimation from the auricular surface of the ilium

The objective of this paper is to test a revised method of age estimation based on the morphology of the auricular surface recently proposed by Buckberry and Chamberlain ([2002] Am. J. Phys. Anthropol. 119:231-239). The study sample consists of 309 individuals of known sex, age, and race from the Terry and Huntington Collections. Auricular surfaces were scored using the revised technique to determine whether it is equally applicable to both sexes as well as blacks and whites. The auricular surfaces of the same individuals were also scored using the original method of auricular surface scoring developed by Lovejoy et al. ([1985] Am. J. Phys. Anthropol. 68:15-28) to determine whether the revised technique is comparable to the original method in terms of accuracy. Results show that the revised method is equally applicable to males and females as well as blacks and whites. The revised method is less accurate than the original method for individuals between 20-49 years of age, but more accurate for individuals between 50-69 years of age.
