“…The Sr isotope composition of bones and teeth of modern and fossil terrestrial vertebrates is widely applied as an isotopic fingerprint to determine the provenance, habitat, and migration of animals and humans (e.g., Vogel et al, 1990;Sillen et al, 1998;Hoppe et al, 1999;Beard and Johnson, 2000;Blum et al, 2000;Price et al, 2002;Bentley, 2006;Feranec et al, 2007;Arppe et al, 2009;Copeland et al, 2011). However, to constrain the provenance and mobility of individuals it is important to know the 87 Sr/ 86 Sr of the bioavailable Sr ingested by the animal or human being, which can best be done by analyzing modern plant and water samples or tissues of modern animals from the area of interest (e.g., Price et al, 2002;Bentley, 2006).…”
