Diets of Pliocene mammals from Omo, Ethiopia, deduced from carbon isotopic ratios in tooth apatite
Abstract Carbon isotopic ratios in tooth apatite of Pliocene fossil mammals from Omo, Ethiopia, dated at 2.0 m.y. ago reported here are consistent with dietary predictions based on modern herbivores of the African savannah. The results indicate the applicability of the technique in reconstructing dietary patterns of fossil animals including hominids.
