Abstract Utilizing the occurrence of plesiadapid mammals, we recognize both Tiffanian and Clarkforkian ages in the Fort Union Formation of the Piceance Creek Basin of Colorado. Five species of plesiadapids are described from eighteen fossil localities. The presence of Nannodectes gazini, Plesiadapis fodinatus and a new species Chiromyoides gigas indicate that at most eleven of the reported fossil localities are Tiffanian in age. The majority of the fossil specimens come from UCM locality 92177… 

Systematics and Paleobiology of Chiromyoides (Mammalia, Plesiadapidae) from the Upper Paleocene of Western North America and Western Europe

Most of the derived anatomical features that distinguish Chiromyoides from closely related plesiadapids indicate that it was yet another occupant of the lucrative ‘mammalian woodpecker’ niche, alongside the extant Malagasy lemur Daubentonia, the extant phalangeroid marsupial Dactylopsila, early Cenozoic placental Apatemyidae, and possibly the middle Cen Jurassic metatherian Yalkaparidon.

Plesiadapid Mammals from the Latest Paleocene of France Offer New Insights on the Evolution of Plesiadapis during the Paleocene-Eocene Transition

There is some indication of morphological convergences between European and North American plesiadapids, which may be the result of similar environmental changes on both continents just before the Paleocene-Eocene boundary.

A new species of the archaic primate Zanycteris from the late Paleocene of western Colorado and the phylogenetic position of the family Picrodontidae

A new species of an archaic primate (Pleisadapiformes) is described based on a maxilla containing the first and second upper molars from the Fort Union Formation, Atwell Gulch Member in northwestern Colorado, showing the rapid diversification of archaic primates shortly after the extinction of the dinosaurs during the Paleocene.

Evolution of plesiadapid mammals (Eutheria, Euarchonta, Plesiadapiformes) in Europe across the Paleocene/Eocene boundary: implications for phylogeny, biochronology and scenarios of dispersal

Comparisons between plesiadapids from Europe and North America indicate a separation from at least the terminal Tiffanian, suggesting correlation of the European reference level MP6 with the North American biozones Ti-5b and Ti-6.

Additions to the latest Paleocene Buckman Hollow local fauna, Chappo Member of the Wasatch Formation, Lincoln County, southwestern Wyoming

With few notable exceptions, mammalian faunas from the latest Paleocene of North America (Clarkforkian North American Land Mammal Age, approximately 57 to 55.7 Ma) are poorly known, with the vast

Fluvial response to abrupt global warming at the Palaeocene/Eocene boundary

The results, combined with evidence for increased dissolved loads and terrestrial clay export to world oceans, indicate that the transient hyper-greenhouse climate of the PETM may represent a major geomorphic ‘system-clearing event’, involving a global mobilization of dissolved and solid sediment loads on Earth's surface.



New North American Plesiadapidae (Mammalia, Primates) and a Biostratigraphic Zonation of the Middle and Upper Paleocene

The stratigraphic and phylogenetic relationships of the species of North American Plesiadapidae are outlined, and the Middle and Late Paleocene is divided into seven superposed biostratigraphic zones based on the evolution of Pronothodectes and PlesiADapis.


ABSTRACT Several recently discovered fossil specimens add to our knowledge of plesiadapiform primates. Micromomys willwoodensis, new species, is a diminutive microsyopid from the early Eocene (early

A New Late Paleocene Vertebrate Fauna from the Ohio Creek Formation of Western Colorado

Abstract Despite recent drilling for hydrocarbon tight-gas resources in conglomerates and sandstones in the Piceance Creek Basin, controversy still exists over the age and lateral extent of the Ohio

Cranial Anatomy and Evolution of Early Tertiary Plesiadapidae (Mammalia, Primates)

The Bighorn Basin of Wyoming is important paleontologically for two reasons: 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, and many areas of the Bighorns are richly fossiliferous, making it possible to trace evolutionary changes through time in much more detail than is possible elsewhere.

Paleocene primates from western Canada

Plesiadapiform primates have been recovered from seven Paleocene sites in western Canada: (1) Roche Percee (Ravenscrag Formation) — Carpodaptes cygneus, Plesiadapis churchilli, Ignacius frugivorus,

Catalogus Mammalium tam viventium quam fossilium

A new catalogue of Mammals is much wanted, and will be of great use to the many workers in that group of animals, although the work appears to have been performed in a satisfactory manner, though it would not be difficult to point out a certain number of slips and errors.

Classification of mammals : above the species level

Malcolm C. McKenna and Susan K. McKenna inherited the project from Simpson and, with Bell, has constructed a completely updated hierarchical system that reflects the genealogy of Mammalia.


The Bighorn Basin of northwestern Wyoming preserves one of the most complete records of middle Paleocene to lower Eocene continental biota. The geochronology of this important interval depends partly

Stratigraphic Variation in the Timing of First and Last Occurrences

Abstract With the exception of the Neogene, it is difficult in much of the fossil record to measure range offset; that is, the difference in age between the first or last occurrence of a species in a

Nomenclature and correlation of the North American continental Tertiary

This report presents a provincial time scale for the North American continental Tertiary. It proposes a standardized terminology of purely temporal significance based on North American mammal-bearing
