AB: The diet and habitat landscape for fossil specimens pertaining to Late Pleistocene horse Equus sp., and mammoth Mammuthus columbi from the deposit at Rancho La Amapola, El Cedral, San Luís Potosí, México were assayed with basis on stable isotopes analysis the carbon and oxygen found in dental enamel apatite. For horses the Δ 13C values showed from C3/C4 a basic C4-plants diet ranging into a C3/C4 mixer feeder, while mammoth showed values as a C3/C4 mixer feeder, but preferring C4 plants; there was not significant differences among the average values for both groups, with -3.5 ‰ for horses and -3.8 ‰ for mammoth. Mexican data was compared with those for the same genera from US localities, including the states of Florida, New Mexico, and Texas, allowing confirmation of the inference that El Cedral species were mainly grazers, but with some C3 plants being consumed; furthermore, comparisons of El Cedral specimens, using both carbon and oxygen isotopes, with Floridan C3-plant sites showed El Cedral specimens could be defined as mixer feeders in open habitats, preferring such opn areas like grassland or savanna. Our results are in agreement with the species dental morphology, as well as with the pollen record for the same site, which showed the existence of grassland that could have extended during the Late Pleistocene from southern Canada to central Mé xico
