Neoplagiaulax
''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. The genus ''Neoplagiaulax'' ("new ''Plagiaulax''") was named by Lemoine V. in 1882. Species *''Neoplagiaulax annae'' (Vianey-Liaud M. 1986) has been found in Paleocene strata of Cernay, France. *''?Neoplagiaulax burgessi'' (Archibald J.D. 1982) has been found in Maastrichtian (Upper Cretaceous) strata of Hell Creek, USA. *''Neoplagiaulax copei'' (Lemoine V. 1885) has been found in Paleocene strata of Cernay, France. It has been cited as a possible descendant of ''N. hazeni''. *''Neoplagiaulax donaldorum'' (Scott C.S., Krause D.W. 2006) found in early Tiffanian (late Paleo ...

Multituberculata
Multituberculata (commonly known as multituberculates, named for the multiple tubercles of their teeth) is an extinct order of rodent-like mammals with a fossil record spanning over 130 million years. They first appeared in the Middle Jurassic, and reached a peak diversity during the Late Cretaceous and Paleocene. They eventually declined from the mid Paleocene onwards, disappearing from the known fossil record in the late Eocene. They are the most diverse order of Mesozoic mammals with more than 200 species known, ranging from mouse-sized to beaver-sized. These species occupied a diversity of ecological niches, ranging from burrow-dwelling to squirrel-like arborealism to jerboa-like hoppers. Multituberculates are usually placed as crown mammals outside either of the two main groups of living mammals—Theria, including placentals and marsupials, and MonotremataAgustí-Antón 2002, pp 3-4—but usually as closer to Theria than to monotremes. They are considered to be clos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tiffanian
The Tiffanian North American Stage on the geologic timescale is the North American faunal stage according to the North American Land Mammal Ages chronology (NALMA), typically set from 60,200,000 to 56,800,000 years BP lasting . It is usually considered to overlap the Selandian and Thanetian within the Paleocene. The Tiffanian is preceded by the Torrejonian and followed by the Clarkforkian NALMA stages. Substages The Tiffanian is considered to contain the following substages: *Ti6: Lower boundary source of the base of the Tiffanian (approximate). *Ti5 Lower boundary source of the base of the Tiffanian (approximate) and upper boundary source of the base of the Clarkforkian (approximate). *Ti4: Lower boundary source of the base of the Tiffanian (approximate) and upper boundary source of the base of the Clarkforkian (approximate). *Ti3: Lower boundary source of the base of the Tiffanian (approximate) and upper boundary source of the base of the Clarkforkian (approximate). *Ti2: L ...

Neoplagiaulacidae
Neoplagiaulacidae is a family of mammal within the extinct order Multituberculata. Fossil remains are known from the Upper Cretaceous through to the latest Eocene/early Oligocene. Representatives have been found in North America, Europe and Asia. They are the last multituberculates known.Karew Schumaker, Multituberculates from the Medicine Pole Hills Local Fauna (Chadronian) of Bowman County, North Dakota Neoplagiaulacinae (Ameghino 1890) has been seen as a sub-family within Ptilodontidae (Cope, 1887). More recent thinking has it as a family. Synonyms are Ectypodidae (Sloan & Van Valen 1965) and Ectypodontidae (Sloan & Van Valen 1965). Most fossils are restricted to teeth. The family is part of the suborder of Cimolodonta Cimolodonta is a taxon of extinct mammals that lived from the Cretaceous to the Eocene.

Cimolodonta
Cimolodonta is a taxon of extinct mammals that lived from the Cretaceous to the Eocene. They were some of the more derived members of the extinct order Multituberculata. They probably lived something of a rodent-like existence until their ecological niche was assumed by true rodents. The more basal multituberculates are found in a different suborder, " Plagiaulacida", a paraphyletic group containing all non cimolodontan multituberculates. Cimolodonta is apparently a natural (monophyletic) suborder. Remains have been identified from across the Northern Hemisphere. They first appeared during the Aptian, and completely replaced the more primitive plagiaulacidans by the early Late Cretaceous. The taxon is recognized as the informal Paracimexomys group and the superfamilies Djadochtatherioidea, Taeniolabidoidea, and Ptilodontoidea. Additionally, and of uncertain affinities, are the families Cimolomyidae, Boffiidae, Eucosmodontidae, Kogaionidae, Microcosmodontidae and the two ...

Peabody Museum Of Natural History
The Peabody Museum of Natural History at Yale University is among the oldest, largest, and most prolific university natural history museums in the world. It was founded by the philanthropist George Peabody in 1866 at the behest of his nephew Othniel Charles Marsh, the early paleontologist. Most known to the public for its Great Hall of Dinosaurs, which includes a mounted juvenile '' Brontosaurus'' and the mural ''The Age of Reptiles,'' it also has permanent exhibits dedicated to human and mammal evolution; wildlife dioramas; Egyptian artifacts; and the birds, minerals and Native Americans of Connecticut. Description The Peabody Museum is located at 170 Whitney Avenue in New Haven, Connecticut, United States, and is operated by almost one hundred staff members. While the original building was demolished in 1917, it moved to its current location in 1925, and has since expanded to occupy the Peabody Museum, the attached Kline Geology Laboratory and the Class of 1954 Environme ...
