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… Expand
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 areExpand
A new species of Sigmodontinae (Rodentia) from the late Hemphillian of central Mexico, and comments on the possible radiation of this group
The Sigmodontinae subfamily represents one of the most diverse groups of mammals in the world; this rodent group evolved in the open and arid ecosystems of the Miocene of North America and was theExpand
Presence of Amphimachairodus coloradensis (Cook, 1922) (Felidae: Machairodontinae) in the Neogene of Hidalgo, Central Mexico
Abstract The Neogene Amphimachairodus coloradensis appears to be one of the most abundant species of Machairodontine in Mexico. However, its fossil record is composed of scarce, fragmented, andExpand
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,Expand
A new Miocene local fauna from the Sierra Madre Oriental at San Luis Potosí, Central-East Mexico, and its paleontologic significance
Abstract Mexico's Late Neogene mammal faunas are largely known from localities in the Trans-Mexican Volcanic Belt; those from other morphotectonic provinces are few and far apart. Thus, the discoveryExpand
First fossil record of a Megatheriidae-Megatheriinae in the Early Hemphillian (Late Miocene) from San Gerardo de Limoncito, Curré Formation, Costa Rica
We report the first record of Megatheriidae-Megatheriinae fossil record in Central and North America, which also represents the earliest record of a Megatheriidae-Megatheriinae outside of SouthExpand
Dietary analysis of Late Cenozoic Mexican equids from three different geographic/geologic settings using stable carbon isotopes: Coincidences, differences and paleobiologic significance
The coeval diet change observed in Mexico and temperate North America implies a correlative vegetation change resulting in the appearance and rapid diversification of C 4 plants, which largely formed the preferred food stuff of equids since the Hemphillian, although some C 3 plant consumption was maintained till the Rancholabrean.

The first Late Eocene continental faunal assemblage from tropical North America
Abstract To date, the terrestrial faunal record of the North American late Eocene has been recovered from its subtropical and temperate regions. We report the first late Eocene continental faunalExpand
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,Expand
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.

Earliest hog-nosed skunk, Conepatus (Mephitidae, Carnivora), from the early Pliocene of Guanajuato, Mexico and origin of South American skunks
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.
