Due to possible systematic differences in stable isotope values between bone and dentine, dentine values need to be transformed into bone-collagen equivalent using a correction factor to allow comparisons between the two collagen sources. Here, we provide correction factors to transform dentine delta C-13 and delta N-15 values into bone-collagen equivalent for two toothed whales: narwhal and beluga. We sampled bone and dentine from the skulls of 11 narwhals and 26 belugas. In narwhals, dentine was sampled from tusk and embedded tooth; in belugas, dentine was sampled from tooth. delta C-13 and delta N-15 were measured, and intra-individual bone and dentine isotopic compositions were used to calculate correction factors for each species. We detected differences in delta C-13 and delta N-15. In both narwhals and belugas, we found lower average delta C-13 and delta N-15 in bone compared with dentine.
