Of these samples, only IGVR 203334, IGVR6 3017-15 and IGVR 63017-2 belong to modern humans, while the last two belong to Suidae and Cervid/Saiga (see Table 2). The isotopic values, C:N ratios and the amount of collagen extracted (Coll %) refer to the >30 kDa fraction. δ13C values are reported relative to the vPDB standard and δ15N values are reported relative to the AIR standard. The calibration was computed by OxCal 4.258 using the International Calibration Curve IntCal1359.
