This study presents results and recommendations arising from a blind test of the revised age estimation method for the auricular surface as proposed by Buckberry and Chamberlain ([2002] Am. J. Phys. Anthropol. 119:321-329). Auricular surfaces of 167 individuals from St. Bride's, London, a documented skeletal assemblage spanning the late 17th to early 19th century, were analyzed for the following traits: transverse organization, surface texture appearance, macroporosity, microporosity, and morphological changes to the apex. Composite scores of trait expressions were found to generally correlate with age and to show a positive association with known chronological age (P < 0.01). However, when composite scores were combined to define auricular surface phases, which ultimately assign age estimations, only three distinct developmental stages, compared with seven suggested by Buckberry and Chamberlain ([2002] Am. J. Phys. Anthropol. 119:321-329), could be identified and statistically supported, all showing a considerable degree of individual variation in age. The most well-defined stage in the St. Bride's assemblage was the new stage III, where the majority of individuals were older than 60 years, whereas middle-aged adults displayed a large variation in composite scores. These results provide little hope for a promising application of age-at-death estimation of auricular surface morphology traits with higher resolution, but rather suggest indications of broad stages of life.
