The Bighorn Basin of Wyoming is important paleontologically for two reasons. First, it is the only place in the world where the early Cenozoic diversification of mammalian life is recorded through such a long sequence of continental sediments representing virtually continuous deposition. The major groups of modern mammals appeared during this interval, and the Bighorn Basin is the best place to study how this happened. Secondly, many areas of the Bighorn Basin are richly fossiliferous, making… 

Primate Origins: A Reappraisal of Historical Data Favoring Tupaiid Affinities

The origin of primates remains a fascinating question but the identification of the living sister group of primates is not clearly settled and the increase in and the enhanced quality of the anatomical and molecular data sets extracted from the living forms did not result in any increased consensus.

Vertebrate paleontology: new approaches and new insights

In the past fifteen years, the biological interpretation of vertebrate fossils has been markedly advanced by the application of experimental techniques in functional morphology, biomechanical and

Modes of evolution and their chronostratigraphic significance: evidence from Devonian invertebrates in the Michigan Basin

The origin and evolutionary histories of the two most abundant and diverse genera of inver- tebrates in the Detroit River Group and associated rocks in the vicinity of the Michigan Basin appear to support the models of either allopatric speciation and punctuated equilibria or quantum evolution.

Cranial anatomy of Paleocene and Eocene Labidolemur kayi (Mammalia: Apatotheria), and the relationships of the Apatemyidae to other mammals

Three new, well-preserved crania of Labidolemur kayi from the late Paleocene (Clarkforkian) and early Eocene (Wasatchian) of North America are described in part using ultra high resolution X-ray computed tomography data, allowing the first descriptions of critical components of apatemyid cranial anatomy.

Origin and Evolution of Gliding in Early Cenozoic Dermoptera (Mammalia, Primatomorpha)

Despite the differences in extant diversity, bats, whales, and colugos are distinctive components of the Earth’s biota primarily because of the suites of diagnostic attributes they possess as a result of the key innovations that occurred earlier in their respective histories.

Early Eocene Paromomyidae (Mammalia, Primates) from the Southern Bighorn Basin, Wyoming: Systematics and Evolution

Overall patterns of dental evolution in southern Bighorn Basin paromomyids provide some support for previously hypothesized periods of faunal change (Biohorizons), and two taxa previously believed to have become extinct at Biohorizon A are shown to have persisted about a million years longer than previously thought.


This study consists of a taxonomic revision of the genus, a detailed description of the osteological morphology, extensive analyses on morphological characters, analyses on phylogeny, discussions on divergence time of the Glires, and analyses on functional morphology of mastication and locomotion.


Phylogeographic analysis of living North American marmots and middle Pleistocene fossils from Porcupine Cave, Colorado revealed that the latter were more closely related to extant Marmota monax than they are to M. flaviventris, suggesting that the origin of living species occurred in regions different from those they inhabit today.



Taphonomy and population dynamics of an early Pliocene vertebrate fauna, Knox County, Nebraska

The principal purpose of this study is to determine from geological and biological evidence how a concentration of fossil bones originated. The Verdigre quarry of earliest Pli— ocene age in the

Fossil Bird Remains from the Eocene of Wyoming

It appears probable that with sufficient study most if not all Eocene species will be allocated in subfamilies and families other than those in existence today.

A New Genus of Fossil Salamander from North America

A new genus and species of fossil salamander, Opisthotriton, from Niobrara County, Wyoming, Lance formation, Upper Cretaceous, is described andishes the presence of the suborder Salamandroidea in the New World during the Mesozoic.

Systematics, Phylogeny, and Evolution of Early Eocene Adapidae (Mammalia, Primates) in North America

The evolution of Pelycodus appears to be continuous and gradual from the earliest to the latest species, and one morphological characteristic, acquisition of symphyseal fusion, appears to coincide approximately with the Wasatchian-Bridgerian (early Eocene-middle Eocene) boundary.


On the tenth of January, 1913, I received from Dr. W. D. Matthew, Curator of the Department of Vertebrate Palaeontology in the American Museum of Natural History, New York City, a small collection of

Sanctimus (Mammalia, Rodentia) and the phyletic relationships of the large Arikareean geomyoids

Sanctimus, represented by three species from the Sharps and Monroe Creek formations of western South Dakota, is similar in size and most dental structures to Florentiamys, a group of large geomyoids,

High-level strata containing early Miocene mammals on the Bighorn Mountains, Wyoming. American Museum novitates ; no. 2490

Fossil mammals of early Miocene age have been found in strata composing Darton's Bluff on the crest of the Bighorn Mountains in the Hazelton Peak Quadrangle, Johnson County, Wyoming. Dating the host

Leptoceratops gracilis from the "Lance" Formation of Wyoming

Leptoceratops is a primitive ceratopsian dinosaur known only from the latest Cretaceous units of Montana, Wyoming, and Alberta, Canada. This genus includes only one species, L. gracilis, and is

Paleocene Hyracothere from Polecat Bench Formation, Wyoming

A lower jaw of an eohippus from late Paleocene strata in Wyoming has extended the geological record of fossil horses into pre-Eocene time and suggests that the order Perissodactyla had an origin earlier than that heretofore conjectured.
