Abstract:	This study examines stable isotope ratios of carbon and nitrogen in bone collagen and the elemental concentrations of strontium in the bone mineral of terrestrial vertebrates from a variety of ecosystems. Documentation of the separation of trophic levels by these indices is essential for the assessment of the trophic position of prehistoric humans. Particular emphasis is given to carnivores in this study as they are generally underrepresented in most archeological assemblages. Nitrogen isotope ratios and strontium p.p.m. values can separate herbivores and carnivores depending upon the scale of the analysis. Separation is more pronounced the smaller the geographic area of the sample.
