Abstract
Use of the first rib for adult age estimation: a test of one method
H Kurki
342 - 350
A method of adult age estimation using the first rib (Kunos et al., [1999]) is tested on a sample of known age skeletons (n = 29, mean age = 55.7 years). The high correlation coefficient (r = 0.69) and moderate coefficient of determination (r2 = 0.47) demonstrate agreement between the known and estimated ages, suggesting that the first rib demonstates morphological changes with age. The inaccuracy and bias are high (all ages inaccuracy = 10.4 years, bias = 4.7 years) but comparable to several other age estimation methods in common use. Although the results are not as good for younger age categories (< 50 years: inaccuracy and bias rank ninth of nine age estimation methods), the inaccuracy and bias for the older age categories are relatively low (60 + years inaccuracy = 8.9 years, ranks third out of nine; bias = - 5.8 years, ranks first out of nine) compared with other age estimation methods. The first rib method is reasonably precise (93% of individuals fall within the limits of agreement of the mean difference between two trials). It is argued that the first rib method is therefore a useful addition to the methods available for biological profile reconstructions from skeletal remains, especially if it is suspected that the remains represent an older individual.
The use of statistical size estimations in minimum number calculations
T J Orchard
351 - 359
It is argued that the use of varied quantitative techniques for reconstructing aspects of the harvested populations in analyses of archaeological faunal assemblages is particularly important with the increasing use of zooarchaeological data outside of the realm of traditional archaeological inquiry. Detailed size estimations of archaeological faunal specimens can be used to distinguish between the remains of individual animals, aiding in the reconstruction of minimum number calculations. Statistical regression provides a particularly useful technique for generating size estimations which may then be used to calculate such modified MNI values. The paper outlines a methodology for utilising regression estimated sizes in MNI calculations, and tests the methodology in the context of a case study involving fish remains from Aleutian Islands archaeological sites. The use of this methodology to generate modified MNI values results in consistent increases over values calculated using traditional MNI approaches. Such an approach, while more costly in terms of required effort, is felt to be preferable to traditional approaches in contexts where detailed size estimations are usefully calculated to answer other research questions.
