Boffius is a genus of mammal from the Paleocene of Europe, which was named by Vianey-Liaud M. in 1979. It is a member of the extinct order of Multituberculata.
Purgatorius is a genus of seven extinct eutherian species typically believed to be the earliest example of a primate or a proto-primate, a primatomorph precursor to the Plesiadapiformes, dating to as old as 66 million years ago. The first remains were reported in 1965, from what is now eastern Montana's Tullock Formation, specifically at Purgatory Hill in deposits believed to be about 63 million years old, and at Harbicht Hill in the late Cretaceous and lower Paleocene Hell Creek Formation. Both locations are in McCone County.
Viverravidae is an extinct family within the clade Carnivoramorpha. They are related to carnivorans, and lived from the early Palaeocene to the Eocene.
Miacis is a genus of extinct carnivorous mammals that appeared in the late Paleocene and continued through the Eocene. The genus Miacis is not monophyletic but a diverse collection of species that belong to the stemgroup within the Carnivoramorpha. As such, most Miacis species belong to the group of early carnivores that represent the ancestors of the modern order, the crown-group Carnivora. However, the species Miacis cognitus is placed not in the stem-group but among the Caniformia, one of the two suborders of the crown-group Carnivora.
The Itaboraian age is a period within the Early Eocene geologic time epoch of the Paleogene, used more specifically with South American land mammal ages (SALMA). It follows the Riochican and precedes the Casamayoran age.
Adapisoriculidae is an extinct family of eutherian mammals present during the Paleocene and possibly Cretaceous. They were once thought to be members of the order Erinaceomorpha, closely related to the hedgehog family (Erinaceidae), because of their similar dentition, or to be basal Euarchontans. They were also thought to be marsupials at one point. Most recent studies show them to be non-placental eutherians, however.
Deccanolestes is a scansorial, basal Euarchontan from the Late Cretaceous (Maastrichtian) and Paleocene Intertrappean Beds of Andhra Pradesh, India. It may be closely related to Sahnitherium. Deccanolestes has been referred to Palaeoryctidae in the past, but recent evidence has shown that it is either the most basal Euarchontan, as the earliest known Adapisoriculid, or as a stem-afrotherian.
Palaeochiropterygidae is a family of extinct bats. It was originally erected by the Swiss naturalist Pierre Revilliod in 1917 after discoveries of Palaeochiropteryx fossils from the Messel Pit of Germany. Palaeochiropterygidae was merged into Archaeonycteridae by Kurten and Anderson in 1980, but modern authorities specializing in bat fossils maintain the distinction between the two. It was classified to the unranked clade Microchiropteramorpha by Smith et al. in 2007.
Proremiculus is an extinct genus of adapisoriculid mammal known from the Paleocene of Belgium.
Afrodon is an extinct genus of eutherians in the family Adapisoriculidae. Its type species is Afrodon chleuhi, known from the late Palaeocene of Morocco. The other known species are Afrodon germanicus from the late Palaeocene of Germany and France, Afrodon tagourtensis from the early Eocene of Morocco, Afrodon ivani from the late Palaeocene of Spain, and Afrodon gheerbranti from the early Paleocene of Belgium. Its range spread from the Cernaysian to the Grauvian in the European land mammal ages.
This article records new taxa of fossil mammals of every kind that have been described during the year 2012, as well as other significant discoveries and events related to paleontology of mammals that occurred in the year 2012.
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. The lizard Cernaycerta and placental mammal Bustylus cernaysi are named after the formation.
Matthesia was a primitive bat genus in the family Palaeochiropterygidae. Matthesia is represented by two species known from the middle Lutetian of Geiseltal, Germany. It may be a junior synonym of Palaeochiropteryx.
Orthaspidotherium was a European Paleocene genus of early herbivorous mammals of the family Phenacodontidae. It was included in the family Meniscotheriidae by Teilhard de Chardin in 1921-1922 and was subsequently separated into the subfamily Pleuraspidotheriinae, before being placed in the family Phenacodontidae where it remains today. The first complete skull, of Orthaspidotherium edwardsi, was described in 2010.
Polydolopimorphia is an extinct order of metatherians, more closely related to extant marsupials than other extinct mammals. Known from the Paleocene-Pliocene of South America and the Eocene of Antarctica, they were a diverse group during the Paleogene, filling many niches, before declining and becoming extinct at the end of the Neogene. It is divided into two suborders, Bonapartheriiformes, and Polydolopiformes
Wyonycteris is a genus of small mammals that existed in the late Paleocene and early Eocene epochs. The type species is Wyonycteris chalix, which lived in Wyoming during the Clarkforkian North American Land Mammal Age of the Paleocene and was originally proposed to be an early form of insectivorous bat. Later re-examination of the material has put this alliance in doubt, and the genus has instead been proposed as belonging to the subfamily Placentidentinae, within the family Nyctitheriidae. Similar fossil material of the same time period found in Europe was later discovered and described as new species, Wyonycteris richardi.
Onychonycteridae is an extinct family of bats known only from the early Eocene of Europe and North America. The type species, Onychonycteris finneyi, was described in 2008 from two nearly complete skeletons found in the Green River Formation of southwestern Wyoming. Since that time a number of previously described fossil bat species have been assigned to Onychonycteridae, as well as another more recently discovered species
Chiromyoides is a small plesiadapid primatomorph that is known for its unusually robust upper and lower incisors, deep dentary, and comparatively small cheek teeth. Species of Chiromyoides are known from the middle Tiffanian through late Clarkforkian North American Land Mammal Ages (NALMA) of western North America, and from late Paleocene deposits in the Paris Basin, France.
Arctocyonians are a clade of laurasiatherian mammals whose stratigraphic range from the Palaeocene to the Early Eocene epochs. They were among the earliest examples of major mammalian predators after the Cretaceous–Paleogene extinction event. While some classify arctocyonians as stem-artiodactyls, others have classified the group as members of Ferae. There are three families classified in the order: Arctocyonidae, Oxyclaenidae, and Quettacyonidae.
The Amphilemuridae are a family of extinct mammals belonging to the order Eulipotyphla, from the Eocene of Europe and North America.
