Zinc isotopes from archaeological bones provide reliable trophic level information for marine mammals
International audience In marine ecology, dietary interpretations of faunal assemblages often rely on nitrogen isotopes as the main or only applicable trophic level tracer. We investigate the geographic variability and trophic level isotopic discrimination factors of bone zinc 66 Zn/ 64 Zn ratios (δ...
