Correspondence Between Stable Carbon, Oxygen and Nitrogen Isotopes in Human Tooth Enamel and Dentine: Infant Diets at Kaminaljuyú

We have previously shown that records of the history of dietary supplementation and weaning can be recovered from isotopic analyses of enamel carbonate in permanent human teeth which form during early childhood. Here, we describe a parallel and complementary record of dietary change in the δ13C and δ15N composition of dentine collagen from the same teeth (a first permanent molar, M1; a premolar, P; a third molar, M3), which are from the …
