Dietary reconstruction of the individuals interred in the Bronze Age burial cist of Ondarre (Aralar, Guipuzcoa) through carbon and nitrogen stable isotope analysis on bone collagen

The results of carbon and nitrogen stable isotope analysis on bone collagen of the individuals interred in the Bronze Age (II millennium cal. BC) cist burial of Ondarre suggest a mixed diet based on C-3 plants and mainly domesticated terrestrial animals. As observed in other contemporary sites in Iberia and the Balearic islands, marine and freshwater resources and C-4 plants do not seem to have played an important role in everyday life subsistence. The observed high protein consumption may relate to the status of the people interred and/or to a dominant livestock economy where animal products would have a great importance in diet.
