Multituberculata is an extinct order of rodent-like mammals with a fossil record spanning over 120 million years. They first appeared in the Middle Jurassic, and reached a peak diversity during the Cretaceous. They eventually declined from the late 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 closer to Theria than to monotremes. Nonetheless, at least one study found a potential status as sister taxa to monotremes/Australosphenida.
Plagiaulacida is a group of extinct multituberculate mammals. Multituberculates were among the most common mammals of the Mesozoic, "the age of the dinosaurs". Plagiaulacids, an informal suborder, are the most basal of this order, and ranged from the Middle Jurassic Period to the Lower Cretaceous Period of the northern hemisphere.
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."
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.
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.
Hahnodon is an extinct genus of mammaliaforms from the Early Cretaceous Ksar Metlili Formation in Morocco. Although originally considered to be a relatively early member of the extinct clade Multituberculata, recent studies indicate that it instead is a haramiyid.
Pinheirodon is a genus of extinct mammal from Portugal. It is a member of the also extinct order of Multituberculata, and shared the world with dinosaurs. It is placed in the suborder "Plagiaulacida" and family Pinheirodontidae.
Bernardodon was a small, Lower Cretaceous mammal from Portugal. It is part of the extinct order Multituberculata, living at the same time as the dinosaurs. Differs from Pinheirodon in having I3 wider and more robust; on P5 the cusps of BB row do not extend for the whole tooth length.
Ecprepaulax is a Lower Cretaceous mammal from Portugal. It was a member of the also extinct order Multituberculata and shared the world with dinosaurs. It lies within the suborder "Plagiaulacida" and family Pinheirodontidae.
Gerhardodon is an extinct genus of mammal from the Lower Cretaceous of southern England. It was a member of the also extinct order of Multituberculata, and lived with such dinosaurs as Iguanodon. It lies within the suborder "Plagiaulacida" and family Pinheirodontidae.
Pinheirodontidae is a poorly known family of fossil mammals which belong to the informal suborder "Plagiaulacida" within the order Multituberculata. Remains are known from the Late Jurassic to earliest Cretaceous of Europe,, but are so far restricted to teeth.
Iberodon is a small, extinct mammal of the Lower Cretaceous from Portugal. It was a member of the also extinct order Multituberculata, and led its obscure and plant-eating existence in the company of dinosaurs. It lies within the suborder "Plagiaulacida" and family Pinheirodontidae.
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".
Loxaulax is a genus of extinct mammal from the Lower Cretaceous of southern England. It was a member of the also extinct order Multituberculata, and lived alongside the dinosaurs. It lies within the suborder "Plagiaulacida" and family Eobaataridae. The genus Loxaulax was named by Simpson G.G. in 1928 based on one species.
Hahnodontidae is a family of extinct mammaliaforms from Early Cretaceous deposits in Morocco and the Western United States. Although originally considered to belong to the extinct clade Multituberculata, recent work indicates that hahnodontids belong to the more primitive clade Haramiyida.
Crusafontia is an extinct genus of mammal from the Cretaceous Camarillas, El Castellar and La Huérguina Formations of Spain. The name of the animal was given in honour of the Spanish paleontologist Miquel Crusafont Pairó.
The Camarillas Formation is a geological formation in the Teruel Province of Aragón, Spain whose strata date back to the Early Cretaceous. The sandstones, mudstones and conglomerates of the formation, that due to syn-sedimentary faulting varies greatly in thickness from 300 to 800 metres, were deposited in fluvial, deltaic and lacustrine environments.
Iberica is an extinct genus of eobaatarid or a possible plagiaulacid multituberculate which existed in what is now Galve, Spain, during the early Cretaceous. It was first named by Ainara Badiola, José Ignacio Canudo and Gloria Cuenca-Bescós in 2011 and the type species is Iberica hahni.
Gideonmantellia is an extinct genus of basal ornithopod dinosaur known from the Early Cretaceous Camarillas Formation of Galve, Province of Teruel, Spain. It contains a single species, Gideonmantellia amosanjuanae.
