Valsequillo biostratigraphy. IV: Proboscidean ecospecies in Paleoindian sites.
Five proboscidean species have been found in Paleoindian sites from North to South America: two open-country adaptations, Mammuthus columbi and Cuvieronius tarijensis, two woodland and riparian forms, Mammut americanum and Mammuthus jeffersonii, and one tropical savanna species, Haplomastodon chimborazi. Their value in biostratigraphy and as ecological index fossils is discussed with particular emphasis on the Central Mexican Paleoindian sites.
