a, Carbon (δ13C) and nitrogen (δ15N) isotopic ratios from bulk collagen of dentine and bone samples. Each point corresponds to a sample; samples from the same individual are connected with a line. The typical analytical error is 0.1‰ for the two isotope systems. VPDB, Vienna PeeDee Belemnite; AIR, atmospheric N2; Ind, individual. b, Zinc (δ66Zn) and strontium (87Sr/86Sr) isotopic ratios from enamel bioapatite. Each point corresponds to a sample; samples from the same individual are connected with a line. The typical analytical error is 0.05‰ for δ66Zn and 7 × 10−6 for 87Sr/86Sr. c, Carbon (δ13C) and nitrogen (δ15N) isotopic ratios from bulk collagen of dentine and bone samples with associated 95% confidence ellipses. Each point corresponds to the average value of all samples coming from a single individual (nindividual = 33; 44 samples in total); the error bars give the standard deviation for all the values from the same individual. d, Zinc (δ66Zn) and strontium (87Sr/86Sr) isotope ratios from enamel bioapatite with associated 95% confidence ellipses. Each point corresponds to the average value of all samples coming from a single individual (nindividual = 33; 41 samples in total); the error bars give the standard deviation for all the values from the same individual.
