Abstract

The morphology of the sternal end of the right fourth rib has been proffered as an accurate age assessor in skeletonized individuals of both sexes. This technique was tested for its applicability on left and right II, III, V–IX. Tests were performed between phase scores obtained from right and left ribs; right rib IV phase scores and scores obtained from the others in the right rib series; and between right rib IV scores and a composite score composed of the average of an individual's phase scores (omitting rib IV). Left ribs IV–IX were found not to vary significantly from their right counterparts. Although only right rib II was found to vary significantly from rib IV, use of the other ribs in the series should be undertaken with caution due to questions concerning their statistical significance. A composite score is therefore recommended for use instead.
