Neoplagiaulax is a mammal genus from the Paleocene of Europe and North America. In the case of the latter continent, there may possibly be some slightly earlier, Upper Cretaceous material too. It existed in the age immediately following the extinction of the last dinosaurs. This animal was a member of the extinct order Multituberculata, lying within the suborder Cimolodonta and family Neoplagiaulacidae.

<i>Titanoides</i> Extinct genus of mammals

Titanoides is an extinct genus of pantodont mammal that lived in North Dakota and as far north as central Alberta. They were up to 3 m (9.8 ft) long and up to 150 kg (330 lb) in weight, being the largest mammals of their habitat, a tropical swampland where the main predators were crocodiles. They had a bear-like appearance with huge canines, short limbs and five clawed digits; however, they were herbivores and probably had traits and attributes more similar to diprotodontids.

<i>Pantolambda</i> Genus of mammals (fossil)

Pantolambda is an extinct genus of Paleocene pantodont mammal. Pantolambda lived during the middle Paleocene, and has been found both in Asia and North America.

<i>Barylambda</i> Pantodont mammal genus from the Paleocene epoch

Barylambda is an extinct genus of pantodont mammal from the middle to late Paleocene, well known from several finds in the Wasatchian DeBeque Formation of Colorado and the Clarkforkian Wasatch Formation to Tiffanian Fort Union Formation in Wyoming. Three species of Barylambda are currently recognized. The creature likely lived a life similar to that of a modern tapir, browsing on foliage and soft vegetation. Barylambda seems to have been quite successful for an early pantodont, though eventually it seems to have been replaced in its ecosystem by other pantodonts, such as Coryphodon.

Pantodonta is an extinct suborder of eutherian mammals. These herbivorous mammals were one of the first groups of large mammals to evolve after the end of the Cretaceous. The last pantodonts died out at the end of the Eocene.

<span class="mw-page-title-main">Arctocyonidae</span> Extinct family of mammals

Arctocyonidae has been defined as an extinct family of unspecialized, primitive mammals with more than 20 genera. Animals assigned to this family were most abundant during the Paleocene, but extant from the late Cretaceous to the early Eocene . Like most early mammals, their actual relationships are very difficult to resolve. No Paleocene fossil has been unambiguously assigned to any living order of placental mammals, and many genera resemble each other: generalized robust, not very agile animals with long tails and all-purpose chewing teeth, living in warm closed-canopy forests with many niches left vacant by the K-T extinction.

Raphictis is an extinct genus of placental mammals from extinct subfamily Didymictinae within extinct family Viverravidae, that lived in North America during late Paleocene.

The Paskapoo Formation is a stratigraphic unit of Middle to Late Paleocene age in the Western Canada Sedimentary Basin. The Paskapoo underlies much of southwestern Alberta, and takes the name from the Blindman River. It was first described from outcrops along that river, near its confluence with the Red Deer River north of the city of Red Deer, by Joseph Tyrrell in 1887. It is important for its freshwater aquifers, its coal resources, and its fossil record, as well as having been the source of sandstone for the construction of fire-resistant buildings in Calgary during the early 1900s.

Edworthia is an extinct genus of paromomyid plesiadapiform which existed in Alberta, Canada, during the early Paleocene. It was first named by Richard C. Fox, Craig S. Scott and Brian D.

Saunders Creek is a ghost town in west-central Alberta, Canada. Built as a coal mining community, the town existed from 1913 to 1954. It is located in the foothills of the Canadian Rockies near the David Thompson Highway, about 55 km west of the town of Rocky Mountain House. It was named for Saunders Creek, a small stream that runs immediately west of the townsite. The North Saskatchewan River flows nearby to the south.

Bemalambda is an extinct mammal, belonging to the pantodonts. It lived in the lower-middle Paleocene and the fossil remains have been found in China.
