The purpose of this research is to examine regional biological variation in Italy during Imperial Roman times (I-III Centuries AD) using three samples exhibiting distinctive class and economic systems. The individuals buried at Isola Sacra and Velia represent middle class tradesmen and merchants from coastal port populations from central and southern Italy respectively; while the individuals from Castel Malnome represent an inland population near Rome of freed slaves and other lower class individuals, involved in heavy labor associated with salt production. Data were recorded from 25 cranial three-dimensional landmark coordinates and analyzed using Procrustes Superimposition and associated multivariate statistics in MorphoJ. Procrustes ANOVA statistics were unable to detect any significant group differences for centroid size or shape (size p=0.5957, shape p=0.1970), suggesting that the three samples are similar to one another. However, canonical variates analyses based on Procrustes distance values indicated that while Castel Malnome was not significantly different from either of the coastal sites (Isola Sacra, p=0.2071 and Velia, p=0.8015); Isola Sacra and Velia were significantly different (p=0.0119). The similarity of Castel Malnome to the other sites may reflect inherent heterogeneity in the sample, as it represents a group of freed slaves likely originating from various geographic locations. The separation of the two coastal sites is not unexpected, as Velia’s location may be influenced by an influx of Greek populations in the southern Italian peninsula. This study was funded in part by a grant from Research and Sponsored Projects, University Enterprises, Inc. at the California State University Sacramento. Frontal Sinus Development and Juvenile Age Estimation KAITLIN M. MOORE, ANN H. ROSS and CHELSEY A. JUAREZ. Department of Sociology and Anthropology, North Carolina State University April 14, 2016 , Atrium Ballroom A/B [image: Add to calendar] <http://meeting.physanth.org/program/2016/session11/moore-2016-frontal-sinus-development-and-juvenile-.ics> Development is an important component of age estimation in juveniles. One area that has not been fully investigated as a possible aging method is the development of the frontal sinus. The predictable growth cycle of the frontal sinus could make it a useful parameter for age estimation. The frontal sinuses form when the ectocranial table of the frontal bone separates from the endocranial table forming an air pocket in the bone. The endocranial table ceases growth with the brain, while the ectocranial table is displaced anteriorly as the facial bones continue growth. In order to examine the utility of the frontal sinuses for age estimation, 387 radiographs were examined (♀=154 and ♂=233) from the Juvenile Radiograph Database at North Carolina State University and the Patricia Database from Mercyhurst University. The sample included individuals who range in age from 0 to 18 years old. Anteriorly positioned radiographs were examined and were then grouped based upon their presence or absence of the frontal sinus. Individuals were divided into four age categories. A one-way ANOVA was run, and then a Tukey adjustment was used to examine the differences in age range between the four groups. Results show that only three of the four groups were significant (p<.0001): individuals with no development (0-5 years), individuals who showed the first signs of sinus development (6-8 years) and individuals with fully developed frontal sinuses (9-18 years). These results indicate that the development of the frontal sinuses can be utilized as a potential method of estimating age. Cranial Bone Mineral Density as a Possible Age IndicatorANNA K. PASCHALL and ANN H. ROSS. Department of Sociology and Anthropology, North Carolina State University April 16, 2016 , Atrium Ballroom A/B [image: Add to calendar] <http://meeting.physanth.org/program/2016/session46/ross-2016-cranial-bone-mineral-density-as-a-possib.ics> Age estimation is traditionally calculated through the macroscopic observation of skeletal degenerative changes. Cranial thickness has been found not to be sexually dimorphic until the onset of *hyperostosis frontalis interna*. Though typically used as an indicator of osteoporotic risk factor, bone mineral density (BMD) may provide a method for age estimation based upon minute changes in mineralization that occur as a result of the aging process. Age changes in BMD was explored in a combined male and female mixed ancestry autopsy sample (N = 32). The sample age range was 17-84. The DEXA scans were performed using a Hologic ® QDR Discovery 4500W scanner. Composite BMD scores for the frontal and parietal bones were calculated. The relationship between age and the frontal and parietal bones was examined using a Kernel smoother or Loess regression, which finds a locally weighted fit of a simple curve. Results show a distinct pattern of BMD and age between the frontal and parietal bones. In the frontal bone, there is a steady increase in BMD until age 35 with a steady decline until age 50 when there is a steep increase in BMD until 58 years of age followed by a steep decline until 62 years of age when BMD scores appear to stabilize. In the parietals, BMD scores are stable until approximately age 33 when there is a steep increase until age 45 followed by an abrupt decline in BMD until age 58 when there is a steady increase in BMD.
