Isotopic evidence for age‐related variation in diet from Isola Sacra, Italy

This study examines collagen (N=105) and apatite (N=65) data from an Imperial Roman skeletal sample from the necropolis of Isola Sacra (Rome, Italy). This paper explores correlations between the isotopic composition of bone samples and the inferred age and sex of these individuals (aged 5--45+ years). The collagen of males, and older individuals in general, was significantly enriched in (15)N but not (13)C. Bone carbonate was somewhat depleted …
