A fairly extensive fossil collection was recovered from the sediments in the central part of the Juchipila graben, which represents the oldest Hemphillian (Hh2) mammalian faunal assemblage so far documented in central Mexico. A large number of fossils of the equid Calippus (Grammohippus) hondurensis were used to correlate the Juchipila local fauna with other isolated Hemphillian records in central Mexico. A skull fragment collected in Juchipila may be referred to Dinohippus mexicanus based on… 

Dinohippus mexicanus (Early-Late, Late, and Latest Hemphillian) and the Transition to Genus Equus, in Central Mexico Faunas

In the advances of the research of the sedimentary basins from central Mexico, it is significant the discovery of the first records of equids of Clarendonian and early Hemphillian age that are

A new species of Sigmodontinae (Rodentia) from the late Hemphillian of central Mexico, and comments on the possible radiation of this group

It is discussed that Baiomys, Prosigmodon, Reithrodontomys and Peromyscus probably diversified in the early Hemphillian (late Miocene), while Sigmodon and Neotoma did so during the late Pliocene.

Taxonomy and notes on the paleobiology of the late Pleistocene (Rancholabrean) antilocaprids (Mammalia, Artiodactyla, Antilocapridae) from the state of Hidalgo, central Mexico

A set of cranial and dental material of Antilocapridae was recovered from Quaternary deposits that outcrop in southeastern Hidalgo, central Mexico. The fossil bearing unit consists of clay, silt,

First fossil record of a Megatheriidae-Megatheriinae in the Early Hemphillian (Late Miocene) from San Gerardo de Limoncito, Curré Formation, Costa RIca

The early record of this xenarthran in Costa Rica is explained by the presence of a land corridor established for short periods of time as a result of tectonic uplift or by a drop in sea level or a mixture of both at approximately 5.8 Ma in Southern Central America.

Diet and habitat of unique individuals of Dinohippus mexicanus and Neohipparion eurystyle (Equidae) from the late Hemphillian (Hh3) of Guanajuato and Jalisco, central Mexico: stable isotope studies

Stable carbon and oxygen isotopes were determined in molar enamel from fossil Pliocene equids from Rancho El Ocote in the San Miguel Allende basin, Guanajuato, and from Santa Maria, Tecolotlan basin,

Increased xenarthran diversity of the Great American Biotic Interchange: a new genus and species of ground sloth (Mammalia, Xenarthra, Megalonychidae) from the Hemphillian (late Miocene) of Jalisco, Mexico

Comparison and analysis of the type specimen, a mandible, shows a closer relationship to South American taxa than those from North America or the Caribbean, which suggests that during the early stages of the Great American Biotic Interchange there were two separate dispersal events of megalonychid sloths.

A basal hog-nosed skunk from the early Pliocene San Miguel de Allende Basin, Guanajuato State, central Mexico is reported, which greatly extends the first appearance of Conepatus from Irvingtonian to early Blancan in North America, more than doubling the time period of previously known appearances.
