— Rationale. Sampling of dentine for stable carbon (δ 13 C) and nitrogen (δ 15 N) isotope ratios in the direction of tooth growth allows the study of temporal changes to the diet and physiological stress of an individual during tooth formation. Current methods of sampling permanent teeth using 1 mm increments provide temporal resolution of 6–9 …
