This thesis examines correlations between age-at-death and changes in the trabecular architecture of the human os pubis, utilizing data from plain film radiography, computed tomography (CT), and micro-CT scans of 65 males from the Grant skeletal collection. Radiography provides researchers with non-destructive options for assessment, digital preservation, and electronic data sharing of human skeletal remains. Plain film radiographs have high spatial resolutions and the required equipment allows for rapid assessment of results even in the field. CT and higher resolution micro-CT, largely unexplored in the field of age estimation, can image trabecular micro-structures in three dimensions at higher contrast resolutions. This study identified continuous quantitative measures of trabecular architecture in plain film radiographs, and CT and micro-CT scans. Potentially robust predictive models derived from these measures achieve correlations (R) with age of .522, .447, and .731, respectively, and improve on the accuracy of traditional qualitative techniques based on discrete morphological phases
