Nitrogen isotopic compositions of Pleistocene Old Crow megafauna.

(a) Bulk collagen nitrogen isotopic compositions (δ15NBulk). Results for woolly mammoths are displayed in blue, other herbivores in purple and carnivores in red. (b) Phenyalanine (source) amino acid nitrogen isotopic compositions (δ15NPhe) of each species. (c) Difference between the nitrogen isotopic composition of glutamate and phenylalanine (Δ15NGlu-Phe) for each species.
