Stable isotope ratio analysis of bone collagen as indicator of different environments conditions and dietary habits in Northeastern Iberia during the 4th and 3rd millenium calBC

The Late Neolithic and Chalcolithic periods are poorly understood in northeastern Iberia. Most of the information comes from the sepulchral structures rather than habitat settlements. The high number of individuals usually recovered from this types of collective burial spaces, together with the low number of direct radiocarbon dates available on them, forces us to be cautious and consider all the studied assemblages as belonging to the so-called Late Neolithic-Chalcolithic time period. To evaluate human dietary patterns of the Late Neolithic-Chalcolithic populations from the northeast of Iberia, stable carbon and nitrogen isotope analysis was carried out on 78 humans and 32 faunal bones fro…
