Figures
- Fig. 1.
Carbon and nitrogen isotope values of bone collagen from Neanderthals and early modern humans from Europe. Errors on the isotope measurements are typically ±0.2‰ for both δ13C and δ15N.
- Fig. 2.
Carbon and nitrogen isotope data for the Oase 1 human and associated fauna taken from Trinkaus et al. (4) and the present study. Errors on the isotope measurements are typically ±0.2‰ for both δ13C and δ15N.

δ13C bone collagen values of directly radiocarbon-dated Neanderthals and early modern humans compared to the average δ13C values of directly radiocarbon-dated herbivores from Northern Europe (34) over the period 50,000 to 20,000 cal BP.
- Fig. 4.
δ15N bone collagen values of directly radiocarbon-dated Neanderthals and early modern humans compared to the average δ15N values of directly radiocarbon dated herbivores from Northern Europe (34) over the period 50,000 to 20,000 cal BP.
