SANCHEZ-SALINAS, Miguel; JIMENEZ-HIDALGO, Eduardo; CRUZ, J. Alberto  and  CASTANEDA-POSADAS, Carlos. New records of Pleistocene mammals from San Mateo Huexoyucán, Tlaxcala and the second Mammuthus juvenile registry in Mexico. Bol. Soc. Geol. Mex [online]. 2020, vol.72, n.1, e240919.  Epub Dec 22, 2020. ISSN 1405-3322.  https://doi.org/10.18268/bsgm2020v72n1a240919.

The fossils from San Mateo Huexoyucan, Tlaxcala, Mexico are formally described in this work. The specimens collected since 2011 include cranial and postcranial ele ments of Pleistocene Megafauna. The iden tification of the elements allows to postulate that they correspond to six previously reported species for the study area (Bison antiquus, Camelops hesternus, Cuvieronius hyodon, Equus conversidens, E. mexicanus and Mammuthus sp.), high lighting the presence of fossil material that corresponds to a juvenile individual of pro boscideans (Mammuthus sp.) and glyptodonts (cf. Glyptotherium floridanum).

Keywords : Megafauna; Rancholabrean; Tlaxcala; Central Mexico; Pleistocene.
