Multituberculata 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 Monotremata—but usually as closer to Theria than to monotremes. They are considered to be closely related to Euharamiyida and Gondwanatheria as part of Allotheria.
Plagiaulacida is a group of extinct multituberculate mammals. Multituberculates were among the most common mammals of the Mesozoic, "the age of the dinosaurs". Plagiaulacids are a paraphyletic grouping, containing all multituberculates that lie outside of the advanced group Cimolodonta. They ranged from the Middle Jurassic Period to the early Late Cretaceous of the northern hemisphere. During the Cenomanian, they were replaced by the more advanced cimolodontans.
Glirodon is a genus of extinct mammal from the Upper Jurassic. It was a relatively early member of the also-extinct order of Multituberculata, suborder "Plagiaulacida". These mammals lived in North America during the Mesozoic, also known as the "age of the dinosaurs".
Paulchoffatia is a genus of extinct mammal of the Upper Jurassic - Lower Cretaceous. It was a relatively early member of the also extinct order Multituberculata, within the suborder "Plagiaulacida" and family Paulchoffatiidae. It lived in Europe during the "age of the dinosaurs."
Bathmochoffatia is an extinct mammal of the Upper Jurassic. It was a relatively early member of the also extinct order Multituberculata. It lived in Portugal at about the same time as the far more famous dinosaur, Allosaurus. It is in the suborder "Plagiaulacida", family Paulchoffatiidae. The genus Bathmochoffatia was named by Hahn G. and Hahn R. in 1998.
Henkelodon was a small mammal of the Upper Jurassic. It was a relatively early member of the extinct order Multituberculata. Henkelodon was a European herbivore that lived during the "age of the dinosaurs". It lies within the suborder "Plagiaulacida" and family Paulchoffatiidae.
Kielanodon is an extinct mammal of the Portuguese Upper Jurassic. It was a relatively early member of the also extinct order of Multituberculata. It eked out a living during the Mesozoic era, also known as the "Age of the Dinosaurs." It is in the suborder Plagiaulacida, family Paulchoffatiidae.
Meketibolodon is a genus of extinct mammal from the Kimmeridgian Camadas de Guimarota of Guimarota, Portugal. It was a relatively early member of the also extinct order Multituberculata, suborder Plagiaulacida, family Paulchoffatiidae. The genus was named by Hahn G. in 1993 based on nine specimens of lower jaw. The type species is Pseudobolodon robustus Hahn 1978.
Meketichoffatia was a small mammal from the Upper Jurassic of Portugal. It was a relatively early member of the extinct order Multituberculata. It lived at the same time as dinosaurs such as Allosaurus. It's within the suborder "Plagiaulacida" and family Paulchoffatiidae.
Plesiochoffatia is an extinct mammal of the Upper Jurassic. It was a relatively early member of the also extinct order Multituberculata. It was a resident of Portugal during the "age of the dinosaurs." It's in the suborder "Plagiaulacida" and family Paulchoffatiidae.
Pseudobolodon was a relatively early member of the also extinct order of mammals, Multituberculata. It lived in Portugal during the Upper Jurassic, part of the "age of the dinosaurs." It lies within the suborder "Plagiaulacida" and family Paulchoffatiidae.
Xenachoffatia is a small Jurassic mammal from Portugal. It was a relatively early member of the also extinct order of Multituberculata. It lived during "the age of the dinosaurs" and belongs to the suborder Plagiaulacida, family Paulchoffatiidae.
Kuehneodon is a genus of extinct mammal of the Upper Jurassic - Lower Cretaceous of Europe. It was a relatively early member of the also extinct order of Multituberculata. Members of this genus lived alongside such dinosaurs as Allosaurus. It belongs to the suborder "Plagiaulacida", family Paulchoffatiidae. In addition, this genus is the only known member of a subfamily called Kuehneodontinae. It was named by Hahn G. in 1969, the name meaning "Kühne’s tooth" in honor of paleontologist Walther Kühne, pioneer of the Guimarota site of Portugal where remains were found in the late 1950s and early 1960s.
Galveodon is an extinct mammal of the Lower Cretaceous. It was a relatively early representative of the also extinct order of Multituberculata. It lived during 'the age of the dinosaurs'. It's within the suborder "Plagiaulacida" and family Paulchoffatiidae.
Paulchoffatiidae is a family of extinct mammals that lived predominantly during the Upper Jurassic period, though a couple of genera are known from the Early Cretaceous. Fossils have been reported from Europe. Paulchoffatiids were members of the order Multituberculata. They were relatively early representatives and are within the informal suborder of "Plagiaulacida". The family was named by G. Hahn in 1969, and it honors the Portuguese geologist Léon Paul Choffat. Two subfamilies are recognized.
Morrisonodon brentbaatar is an extinct multituberculate mammal from the Upper Jurassic Morrison Formation of North America.
Proalbionbaatar is a small mammal from the Upper Jurassic of Guimarota, Portugal. It's the most derived member of the order Multituberculata known from that locality, and shared the world with the much larger dinosaurs. It lies within the suborder "Plagiaulacida" and family Albionbaataridae.
Eobaatar is a genus of extinct mammal from the Lower Cretaceous of Mongolia, Spain and England. A member of the also extinct order Multituberculata, it lies within the suborder Plagiaulacida and family Eobaataridae. The genus Eobaatar was named by Kielan-Jaworowska Z., Dashzeveg D. and Trofimov B.A. in 1987. Its name was made from Greek "eos" = "dawn" and Mongolian "baatar" = "hero"", "warrior".
Ferugliotherium is a genus of fossil mammals in the family Ferugliotheriidae from the Campanian and/or Maastrichtian period of Argentina. It contains a single species, Ferugliotherium windhauseni, which was first described in 1986. Although originally interpreted on the basis of a single brachydont (low-crowned) molar as a member of Multituberculata, an extinct group of small, rodent-like mammals, it was recognized as related to the hypsodont (high-crowned) Sudamericidae following the discovery of additional material in the early 1990s. After a jaw of the sudamericid Sudamerica was described in 1999, these animals were no longer considered to be multituberculates and a few fossils that were previously considered to be Ferugliotherium were assigned to unspecified multituberculates instead. Since 2005, a relationship between gondwanatheres and multituberculates has again received support. A closely related animal, Trapalcotherium, was described in 2009 on the basis of a single tooth.
Ferugliotheriidae is one of three known families in the order Gondwanatheria, an enigmatic group of extinct mammals. Gondwanatheres have been classified as a group of uncertain affinities or as members of Multituberculata, a major extinct mammalian order. The best-known representative of Ferugliotheriidae is the genus Ferugliotherium from the Late Cretaceous epoch in Argentina. A second genus, Trapalcotherium, is known from a single tooth, a first lower molariform, from a different Late Cretaceous Argentinean locality. Another genus known from a single tooth, Argentodites, was first described as an unrelated multituberculate, but later identified as possibly related to Ferugliotherium. Finally, a single tooth from the Paleogene of Peru, LACM 149371, perhaps a last upper molariform, and a recent specimen from Mexico, may represent related animals.
