Abstract Using carbon and oxygen isotopic relationships from dental enamel, diet and habitat were inferred for both mesomammals and megamammals that lived in Cedral (San Luis Potosi, north-central México) during Late Pleistocene time. δ 13 C and δ 18 O values show that bison, some horses and mammoth were eating C 4 plants and lived in open areas, while tapir, camel and some llamas ate C 3 plants and inhabited closed areas. All other studied herbivores (pronghorn, glyptodont, mylodont ground sloth, javelina, mastodon, and other llamas, horses and mammoth) had a C 3 /C 4 mixed diet, living in areas with some percentage of tree coverage. On the other hand, American lion and dire wolf ate either C 4 or mixed-diet herbivores, and short-faced bear ate C 3 herbivores. At Cedral, more humid conditions existed than presently, allowing the presence of a forested area near the grassland.
