The rodent family Geomyidae is native to America. It comprises six extant genera with 40 species distributed from Saskatchewan, Canada to northern Colombia. Two subfamilies are included in the family, the extinct Entoptychinae, with a fossil record ranging from the late Oligocene (Arikareean) to the middle Miocene (Barstovian) and the Geomyinae, with a chronological range from middle Miocene (Barstovian) to Recent. Here, we describe a new species of Gregorymys, G. veloxikua, the oldest known… Expand
A new species of the gopher Gregorymys (Rodentia, Geomyidae) from the early Oligocene (Arikareean 1) of southern Mexico
Abstract. A new species of gopher, Gregorymys mixtecorum n. sp., is described from the Arikareean 1 (early Oligocene) of Oaxaca, southern Mexico. Phylogenetic analysis indicates that it is the sisterExpand
Rodents (Mammalia) from the Troublesome Formation, Late Oligocene to Miocene (Middle Arikareean–Early Clarendonian) of Colorado
ABSTRACT The Troublesome Formation of northcentral Colorado ranges in age from the middle Arikareean North American Land Mammal Age (NALMA: latest Oligocene) to the early Clarendonian NALMAExpand
New Gophers (Rodentia: Geomyidae) from the Cabbage Patch Beds of Montana (Renova Formation) and the Phylogenetic Relationships Within Entoptychinae
ABSTRACT Entoptychine gophers are a species-rich subfamily of the Geomyidae from the Oligo-Miocene known from countless teeth, numerous jaws, and rare skulls and skeletons. Because of this richExpand
Locomotory adaptations in entoptychine gophers (Rodentia: Geomyidae) and the mosaic evolution of fossoriality
TLDR
A quantitative study of the cranial and postcranial remains of eight different species of entoptychine gophers as well as many contemporary rodent species finds a range of burrowing capabilities within EntoptyChinae, including semifossorial scratch‐digging animals and fossorial taxa with cranial adaptations to burrowing.

The first Paleogene mustelid (mammalia, Carnivora) from southern North America and its paleontologic significance
Abstract Mustelidae are the largest and most diverse family of carnivores, its record dates back to the Early Oligocene, and its early history occurred in western Europe; therefore, the finding of aExpand
Burrow systems evince non-solitary geomyid rodents from the Paleogene of southern Mexico
TLDR
Morphological complexity suggests that the burrows were excavated and inhabited by more than one individual, indicating that Oligocene Gregorymys of southern Mexico would be a unique gregarious geomyid. Expand
Earliest Arikareean (later early Oligocene) Iniyoo local Fauna from Chilapa Formation of Santiago Yolomécatl area in northwestern Oaxaca, southern Mexico
Abstract Strata containing the Iniyoo Local Fauna (LF) crop out in the outskirts of Santiago Yolomecatl in the Yolomecatl Subbasin of the southeastern Tlaxiaco Basin in northwestern Oaxaca, southernExpand
Biomechanical adaptations for burrowing in the incisor enamel microstructure of Geomyidae and Heteromyidae (Rodentia: Geomyoidea)
TLDR
The occurrence of modified radial enamel in lower incisors of scratch‐digging Geomyidae and Heteromyidae is regarded as the retention of a plesiomorphic character that is selectively neutral, and is a strong, genetically anchored argument for the close phylogenetic relationship of Geomy family members on the dental microstructure level.

How much variation is in the shape of fossil pupation chambers? An exploratory geometric morphometric analysis of Fictovichnus gobiensis from the Late Eocene of Oaxaca, southern Mexico
TLDR
Geometric morphometrics was used to analyze variation of shape in Fictovichnus gobiensis, a fossil pupation chamber produced by Coleoptera to analyze diverse clusters of similarly shaped pupal chambers, indicative of several coleopteran producers. Expand

TLDR
Heliscomyids are more diverse in the Ridgeview local fauna than in any other Arikareean fauna in North America, which increases the known diversity of this family during a time interval from which only a single species was previously recognized. Expand

DNA Data Support a Rapid Radiation of Pocket Gopher Genera (Rodentia: Geomyidae)
TLDR
It is concluded that diversification within the Geomyini likely occurred during a geologically brief period in the Blancan, and rapid climate change during the Blancans, the origin of patchily distributed grasslands, and the evolution of hypsodonty may have triggered the rapid diversification that eventually produced the five extant genera.

Morphology of the four known skulls of the early Arikareean Hitonkala andersontau Macdonald indicates that this species is a member of the Florentiamyidae, the immediate sister group of the Heliscomyidae. Expand
Morphological phylogenetics of Puya subgenus Puya (Bromeliaceae)
TLDR
In the analysis that included all characters, a single most parsimonious tree was found that supported subgenus Puya by two synapomorphic character states, including the diagnostic character of a sterile inflorescence branch apex and a blooming pattern in which flowers open gradually from base to apex.
