Strontium in Fossil Bones and the Reconstruction of Food Chains

Heinrich Toots 1 and M. R. Voorhies 1

The strontium content of bone is a function of the strontium content of the ingested food. Under favorable conditions of fossilization it can be used for the determination of feeding habits of extinct terrestrial vertebrates. Homogeneous samples of fossil biotic communities are a prerequisite for significant results.
