“…This study aimed to apply the method devised by Verzeletti et al (2010Verzeletti et al ( , 2013 to an autopsy sample of individuals from Southern Spain (58 males and 36 females; 18 to 89 years of age) to determine the accuracy of the novel Components method in this population, and to develop regression formulae specific to a Spanish population (if required). Substantial intra-observer agreement was recorded for the articular surface (K = 0.70), anterior and posterior rib wall (K = 0.63) and superior and inferior rib edge scores (K = 0.72) (Landis & Koch 1977).…”

Contemporary research in the field of forensic anthropology has been diversified and aided by the use of medical imaging technology, which is increasingly being utilised to produce estimates of chronological age as part of the biological profile of an unidentified deceased individual, or a living individual whose age is contested.

“…Calcification can be observed histologically during the first decade of life, and radiologically after the second decade (Rejtarova et al 2009). Many studies have used the fourth costal cartilage for estimating age (Iscan et al 1984a(Iscan et al , b, 1985Inoi 1997;Dedouit et al 2008;Fanton et al 2010;Verzeletti et al 2013;Cerezo-Roman and Hernandez Espinoza 2014;Haj Salem et al 2014), and some researchers have analyzed the first ribs (King 1939;Kampen et al 1995;Barchilon et al 1996;Kunos et al 1999), showing that calcification of the costal cartilage of the first rib is different to that of the other ribs (King 1939;Kampen et al 1995;Barchilon et al 1996;Kunos et al 1999). However, the costal cartilage of the first rib overlaps with the clavicle and soft tissue, and this makes it difficult to extract only the first costal cartilage from a CT image.…”

Estimating Age at Death Based on Costal Cartilage Calcification

Age estimation is a crucial part of forensic investigations. Because different parts of the body are often found at crime scenes, it is important to explore the regions that can be used for age estimation. Previous studies have used simple X-ray to analyze changes in costal cartilage calcification as a measure of age. Here, we tested whether age could be better estimated using measurements of costal cartilage calcification on postmortem CT images. In this study, male and female decedents (n = 10 each) from autopsy cases were grouped into 10-year incremental age groups (20-29 y; 30-39 y; up to 89 y). We found that the mean Hounsfield unit (CT number) and percentage calcification (the ratio of the ossified area to the whole area) increased with age for both sexes. However, there were marked individual differences within many of the groups, and this led to a statistically significant difference (P < 0.05) only between the 20-29 y group and the older age groups. To improve the ability to correctly assign cases to age groups, we introduced and reanalyzed the data using Bayesian statistics. This improved the classifications rates, with 40% of males and 35% of females correctly assigned into their age groups. Broadening the age range could further improve the number of matches. Thus, combining Bayesian statistics with CT imaging can be used to estimate age at death from costal cartilage calcification, and could be used as an adjunct in forensic investigations.

“…Age-at-death was estimated based on the morphology of the pubic symphysis (Brooks & Suchey, 1990) and the iliac auricular surface (Lovejoy et al, 1985). The cranial sutures and sternal rib end morphology (Verzeletti et al, 2010(Verzeletti et al, , 2013 were examined in cases of poor preservation of the pelvis. Specific occupations are not possible to identify from the human skeleton alone (Jurmain et al, 2012).…”

Sex differences in mechanical stress and associated labor in Hellenistic–early Roman Menainon, Sicily

This paper explores mechanical stress in the Hellenistic/early Roman community of Menainon (Sicily) to test the existence of sex‐based division of labor. For this purpose, human skeletal remains from 79 males and 65 females, dating to the 4th–1st ca. BCE, were examined for degenerative joint disease, intervertebral disc disease, cross‐sectional geometric properties, and entheseal changes. Our findings support an equal share of workload between males and females, who appeared to have experienced similar mechanical stress levels. In contrast, they do not support a systematically greater mechanical load among males, as would have been expected if females had been restricted indoors taking care of domestic tasks only, while men had dealt with most physically demanding outdoor activities. The patterns identified in the current study agree with a scenario where agriculture was a prominent subsistence activity (as attested historically for this region) and most members of this rural community engaged in agricultural tasks irrespective of sex. Our study has limitations regarding the available historical and archaeological information, which restrict our ability to formulate solid research hypotheses or fully contextualize the bioarchaeological results. Nonetheless, it does highlight the importance of critically assessing historical information regarding the role of men and women in the Greco‐Roman society.
