From: Zinc isotopes from archaeological bones provide reliable trophic level information for marine mammals

Fig. 3

Isotopic composition (δ15N, δ13C versus δ66Zn) of U. maritimus (magenta circles), P. hispida (brown squares), P. groenlandicus (green triangle) and D. leucas (blue stars) bones for the SfFk-4 (a, c) and combined KkDo-1 and JfEl-4 sites (b, d). For (a) and (c) we present n = 5 U. maritimus, n = 8 P. hispida and n = 4 P. groenlandicus bone samples and for (b) and (d) n = 7 U. maritimus, n = 18 P. hispida, n = 7 P. groenlandicus and n = 2 D. leucas bone samples. Error bars represent the measurement uncertainty.
