A New, Early Puercan (Earliest Paleocene) Species of Purgatorius (Plesiadapiformes, Primates) from Saskatchewan, Canada
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 duringExpand
First evidence of a venom delivery apparatus in extinct mammals
Numerous non-mammalian vertebrates have evolved lethal venoms to aid either in securing prey or as protection from predators, but modern mammals that use venoms in these ways are rare, including onlyExpand
New craniodental material of Pronothodectes gaoi Fox (Mammalia, "Plesiadapiformes") and relationships among members of Plesiadapidae.
Plesiadapidae are a family of Paleogene mammals thought to have phylogenetic affinities with modern Primates. We describe previously unpublished dentitions and the first skull and isolated petrosalsExpand
Abstract The Paskapoo Formation in central and south central Alberta, Canada, preserves continental sediments of Paleocene age. Outcrops of the formation on Nose Creek in northeast Calgary, at aExpand
New earliest Tiffanian [Late Paleocene] mammals from Cochrane 2, Southwestern Alberta, Canada
New mammalian fossils at Cochrane 2, Paskapoo Formation, Alberta, Canada, document five new species and two new combinations: Ptilodus gnomus sp. nov. and Baiotomeus russelli sp. nov.Expand
New Early Carnivoran Specimens from the Puercan (Earliest Paleocene) of Saskatchewan, Canada
Abstract New specimens of an as yet unidentified carnivoran from the earliest Paleocene of Saskatchewan are described. The new specimens augment the evidence on which the contentious earliest (middleExpand
A new, unusual therian mammal from the Upper Cretaceous of Saskatchewan, Canada
Abstract An incomplete lower jaw with teeth documents the presence of a new genus and species of placental mammal from the Upper Cretaceous (Lancian; late Maastrichtian) Frenchman Formation,Expand
Review of Stagodontidae (Mammalia, Marsupialia) from the Judithian (Late Cretaceous) Belly River Group of southeastern Alberta, Canada
Although stagodontid marsupials are among the most distinctive mammals of Late Cretaceous age in North America, there remain significant gaps in knowledge of their dental anatomy, particularly thatExpand
Species composition of the Late Cretaceous eutherian mammal Paranyctoides Fox
Although the known record of Mesozoic eutherian mammals has been significantly enriched in recent years, early eutherian evolution is still not well understood. Among the more controversial ofExpand
Edworthia Lerbekmoi, A New Primitive Paromomyid Primate from the Torrejonian (Early Paleocene) of Alberta, Canada
Abstract A primitive paromomyid plesiadapiform primate, Edworthia lerbekmoi new genus and species, is described from a recently discovered locality in the Paskapoo Formation, exposed at a road cut inExpand
