abstract

• Abstract: The diet of the Clarendonian-early Hemphillian Pliohippus potosinus from the Paso del Águila local fauna, San Luis Potosí, central Mexico, was investigated using carbon and oxygen biogeochemical markers recovered from the dental enamel. Results indicate that P. potosinus was a mixed C3/C4 feeder with an important consumption of C4 plants, and that lived in a savanna. The lithic, structural and palynomorph records show the coexistence there of low lands and savanna plant taxa, quite probably the habitat of P. potosinus and of the camels present in this local fauna, with mountain slopes where forest taxa thrived, and constituted the habitat of cervids, also members of this fauna. © 2021, Pleiades Publishing, Ltd.
