Possibilities and Limitations of the Use of Stable Isotopes (δSuperscript13/SuperscriptC and δSuperscript15/SuperscriptN) from Human Bone Collagen and Carbonate as an Aid in Migration Studies
In: Impact of the Environment on Human Migration in Eurasia, pp. 125–135, Springer, Dordrecht. NATO Science Series: IV: Earth and Environmental Sciences. (ISBN: 978-1-4020-2655-3 978-1-4020-2656-0).
Stable isotope data (δ13C and δ15N) from bone collagen are dietary indicators. The isotopic fractionation of the carbon and nitrogen atoms in the amino acid chains from collagen reflects the isotopic fractionation in the food proteins. Stable isotope values make it possible to distinguish herbivores from carnivores, and to further distinguish between marine and terrestrial sources of food.
