A New, Early Puercan (Earliest Paleocene) Species of Purgatorius (Plesiadapiformes, Primates) from Saskatchewan, Canada

  author={Richard C. Fox and Craig S. Scott},
Abstract The early Paleocene Purgatorius Van Valen and Sloan is the most primitive plesiadapiform primate yet discovered, mostly known from middle to late Puercan strata in Montana, deposited during the interval C29N of the geomagnetic polarity time scale. Here we describe Purgatorius coracis n. sp. from the Ravenscrag Formation, at the Rav W-1 horizon, Medicine Hat Brick and Tile Quarry, southwestern Saskatchewan. This horizon occurs within C29R, making P. coracis the earliest known primate… 

Second known occurrence of the early Paleocene plesiadapiform Pandemonium (Mammalia: Primates), with description of a new species

Pandemonium hibernalis sp. nov., from a middle? Puercan (earliest Paleocene) locality in the upper Scollard Formation, Wintering Hills, southern Alberta, represents the second discovered occurrence

A ‘giant’ purgatoriid (Plesiadapiformes) from the Paleocene of Montana, USA: mosaic evolution in the earliest primates

The large lower canine and the greater development of trenchant molar crests suggest that U. perpetior was more insectivorous, differing appreciably from the omnivorous niche long hypothesized for Purgatorius and purportedly marking the insectivore–primate transition.

A new species of the basal plesiadapiform Purgatorius (Mammalia, Primates) from the early Paleocene Ravenscrag Formation, Cypress Hills, southwest Saskatchewan, Canada: further taxonomic and dietary diversity in the earliest primates

A new species of Purgatorius is described, from the early Paleocene (Puercan) Ravenscrag Formation of southwestern Saskatchewan, that extends the range of purgatoriid dental disparity toward greater omnivory than had been known before.

An Unusual Early Primate from the Paleocene Paskapoo Formation, Alberta, Canada

Molar morphology in P. puncticuspis implies emphasis on vertical piercing and shearing, specializations for insectivory unlikely to have been derived via reversal from plesiadapiform ancestors having more bunodont molars adapted for omnivory/frugivory.

Cf. Wortmania from the early Paleocene of Montana and an evaluation of the fossil record of the initial diversification of the Taeniodonta (Mammalia)

The Garbani Channel deposits, part of the Tullock Formation exposed in northeastern Montana, have yielded a large sample of vertebrates that probably lived during the Puercan 3 North American Land

Geological setting of vertebrate microfossil localities across the Cretaceous–Paleogene boundary in southwestern Saskatchewan, Canada

The Frenchman and Ravenscrag formations of southwestern Saskatchewan, Canada, record an apparently continuous sequence of nonmarine clastic sediments across the Cretaceous–Paleogene (K–Pg) boundary.

The European Paromomyidae (Primates, Mammalia): taxonomy, phylogeny, and biogeographic implications

A cladistic analysis of the European paromomyids found that Arcius is recovered as monophyletic, which is consistent with a single migration event from North America to Europe around the earliest Eocene through the Greenland land bridge.

Resolving the relationships of Paleocene placental mammals

The largest cladistic analysis of Paleocene placentals to date is presented, from a data matrix including 177 taxa (130 of which are Palaeogene) and 680 morphological characters, and supports an Atlantogenata–Boreoeutheria split at the root of crown Placentalia, the presence of phenacodontids as closest relatives of Perissodactyla, and the validity of Euungulata.




Abstract The earliest unquestionable records of Purgatorius (Plesiadapiformes, Primates?, Mammalia) in northeastern Montana and other areas of the Western Interior of North America are of early

New primitive carnivorans (Mammalia) from the Paleocene of western Canada, and their bearing on relationships of the order

It appears that carnivorans and creodonts share no uniquely derived character states of the dentition that might indicate they are sister-groups, and that carnivors are not sister- groups to other eutherian orders.

Mammals from the end of the age of dinosaurs in North Dakota and southeastern Montana, with a reappraisal of geographic differentiation among Lancian mammals

An end-Cretaceous nonavian dinosaur extinction and an early Paleocene mammalian radiation is documented primarily in stratigraphic sequences in eastern Montana. To determine how representative these

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,

Magnetostratigraphic and Biostratigraphic Correlations of Maastrichtian to Early Paleocene Strata Between South-Central Alberta and Southwestern Saskatchewan

ABSTRACT Maastrichtian and Lower Paleocene continental sediments exposed in the Red Deer Valley of south-central Alberta (Horseshoe Canyon, Whitemud, Battle, Scollard and Paskapoo formations) are

The recovery and subsequent prolific radiation of mammals in the northern Western Interior of North America following the Cretaceous–Paleogene (K–P) boundary is well documented in rocks attributed to

A new species of Purgatorius (Mammalia; Primatomorpha) from the Lower Paleocene Bear Formation, Crazy Mountains Basin, south-central Montana

Purgatorius titusi, represented by 51 teeth and jaw fragments, is described from the lower Paleocene Bear Formation of the Crazy Mountains Basin in south-central Montana and is heretofore the earliest occurring species of well-represented primatomorphs.

New Adapisoricidae, Pentacodontidae, and Hyopsodontidae (Mammalia, Insectivora and Condylarthra) from the Late Paleocene of Wyoming and Colorado

Three new genera and species of Adapisoricidae are described from middle Tiffanian Cedar Point Quarry: Litocherus zygeus, Cedrocherus ryani, and DiacocherUS rneizon, and two new species of Hyopsodontidae are recorded from middle and late Tiffanian faunas.
