Paleoenvironment in four Mexican sites of the late Pleistocene with human activity inferred from their fauna. Bol. Soc. Geol. Mex [online]. 2019, vol.71, n.2, pp.343-358.  Epub 30-Oct-2019.

The environment of four late Pleistocene Mexican sites, with human presence, was inferred using carbon and oxygen stable isotope relationships from herbivores enamel, which lived at those sites and was obtained from previous studies. Those analyses showed the presence of forest with grasslands at the sites Fin del Mundo, Rancho La Amapola, and Valsequillo, while Tocuila had grasslands and more humid environmental conditions than at present. At the four localities, these environments favored the coexistence of several herbivorous species and allowed the establishment of the first people in Mexico.
