摘要：
The difference between C-13 isotopic abundances in bone organic matter (collagen) and the mineral phase (carbonate hydroxylapatite) is used for the determination of the trophic level of the animal, especially on fossil samples. This difference is greater for herbivore mammals from cold and temperate areas than for South African herbivore mammals studied previously (8.4 +/- 1.4 parts per thousand versus 6.8 +/- 1.4 parts per thousand respectively). This larger value should be used in the interpretation of isotopic abundances of C-13 in fossil mammals from temperate and arctic areas.
