Bone collagen δ¹⁵N values of fauna, Neandertals, and early modern humans showing significant freshwater aquatic resource exploitation from Eurasian contexts. The early modern humans have higher δ¹⁵N values, indicating consumption of aquatic foods. Measurement error bars are indicated on the early modern human and Neandertal data points, whereas the bars on the freshwater fish and herbivore points indicate typical ranges of values (see text for references). Abbreviations for the early modern humans are K, Kostenki; B, Brno-Francouzská; DV, Dolni Vĕstonice; and M, Mal'ta. Early modern humans showing evidence for terrestrial herbivore consumption (Sunghir) and marine resource exploitation (Paviland) are not included.
