INVESTIGATING INTRA-INDIVIDUAL DIETARY CHANGES AND C-14 AGES USING HIGH-RESOLUTION delta C-13 AND delta N-15 ISOTOPE RATIOS AND C-14 AGES OBTAINED FROM DENTINE INCREMENTS

摘要

Ten medieval permanent teeth were subjected to incremental dentine sectioning and stable isotope analysis to investigate dietary changes in high resolution. In addition to this, eight increments were also selected for radiocarbon measurements to examine possible intra-individual age differences. Results reveal the cessation of weaning, various dietary profiles, and in some cases significantly different C-14 ages obtained from a single tooth. This case study illustrates how C-14 measurements can function as a proxy alongside the commonly used carbon and nitrogen stable isotope values to interpret the diet of past individuals.
