Conglomérat De Cernay
The Conglomérat de Cernay is a geologic formation in Champagne-Ardenne, northern France. It preserves fossils dating back to the Thanetian stage of the Paleocene period.Conglomérat de Cernay at Fossilworks.org The lizard '' Cernaycerta'' and placental mammal '' Bustylus cernaysi'' are named after the formation.

Formation (stratigraphy)
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics (lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness (geology), thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dissacus
''Dissacus'' is a genus of extinct carnivorous jackal to coyote-sized mammals within the family Mesonychidae, an early group of hoofed mammals that evolved into hunters and omnivores. Their fossils are found in Paleocene to Early Eocene aged strata in France, Asia and southwest North America, from 66 to 50.3 mya, existing for approximately . Orientation patch analysis of the molar teeth of the North American ''D. praenuntius'' suggests it was an omnivore that ate a lot of meat, not an exclusive meat-eater like a cat or weasel. It shared its environment with more omnivorous mammals of a similar body size. Though they are not ancestral to Carnivora, ''Dissacus'' species may have had similar roles in Paleocene-early Eocene environments as the foxes and other small canids that evolved later: generalized hunters who also ate fruit or other foods, and caught small animals that lived on the ground. The bear-sized ''Ankalagon'' is closely related to ''Dissacus''. Some paleontologists c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paschatherium
''Paschatherium'' is a small extinct mammal of the Perissodactyla order, with an insectivore-like dentition. Its morphology indicates an arboreal form, adapted climbing and running on trees. ''Paschatherium'' must have been extremely numerous in the latest Paleocene and earliest Eocene of Europe, since it makes up the majority of all mammal fossils in some fossil sites. ''Paschatherium'' has been viewed as a possible ancestor of our modern elephants, sea cows and hyrax Hyraxes (), also called dassies, are small, thickset, herbivorous mammals in the order Hyracoidea. Hyraxes are well-furred, rotund animals with short tails. Typically, they measure between long and weigh between . They are superficially simil ...es.. However, a 2014 cladistic analysis places it within stem perissodactyls.

Hainina
''Hainina'' is an extinct mammal genus from the latest Cretaceous to the Paleocene of Europe. Genus The genus ''Hainina'' ("from Hainin") was named by Vianey-Liaud M. in 1979. This genus was originally referred to as Cimolomyidae. "We assign ''Hainina'' to the Kogaionidae (superfamily ''incertae sedis''); it differs from ''Kogaionon'' in having ornamented enamel, while the enamel is smooth in ''Kogaionon''".Kielan-Jaworowska & Hurum, 2001, p. 409 Material has also been reported from the Upper Cretaceous of Romania.
