Stable Isotope Data of Neolithic and Eneolithic Populations in Bulgaria and Romania, 6600 to 4000 BC

Stable isotopic ratios of carbon and nitrogen performed on collagen and tooth enamel offer invaluable insight into the diet of ancient populations. In the northern Balkans, most of these isotopic data have been collected as auxiliary information of radiocarbon dates, to correct a potential marine reservoir effect. In order to facilitate the access of the academic community to these data, we present a set of isotopic carbon and nitrogen ratios of human samples from the Neolithic and Eneolithic period in Bulgaria and Romania. This collection presents data on 248 individuals from 13 sites that have been previously published in various articles, together with hitherto unreleased isotopic data for individuals from four Romanian sites.
