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.
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".
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.
Sunnyodon is a genus of tiny, extinct mammal, probably of the Lower Cretaceous. Found in what is now southern England and Denmark, it was a relatively early member of the extinct order of Multituberculata. It is part of 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 earliest Cretaceous. Some undescribed fossils from the Middle Jurassic of England may represent earlier versions. Remains have been reported from Portugal, Spain and England. 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.
Bolodon is a genus of extinct mammal from the Lower Cretaceous of Europe and North America. It was a member of the extinct order of Multituberculata and belongs to the suborder Plagiaulacida and family Plagiaulacidae.
Albionbaataridae is a family of small, extinct mammals within the order Multituberculata. Fossil remains are known from the Upper Jurassic and Lower Cretaceous of Europe and Asia. These herbivores lived their obscure lives during the Mesozoic, also known as the "age of the dinosaurs." They were among the more derived representatives of the informal suborder "Plagiaulacida". The taxon Albionbaataridae was named by Kielan-Jaworowska Z. and Ensom P.C. in 1994.
Albionbaatar is an extinct mammal from the Lower Cretaceous Lulworth Formation of England. It was a member of the also extinct order Multituberculata and shared the world with the much larger dinosaurs. It is in the suborder "Plagiaulacida", family Albionbaataridae. The genus Albionbaatar was named by Kielan-Jaworowska Z. and Ensom P.C. in 1994 based on a single species.
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".
Monobaatar is a genus of extinct mammal from the Lower Cretaceous of Mongolia. It was within the also extinct order Multituberculata, and lived during the "age of the dinosaurs". It is also within the suborder "Plagiaulacida" and has been tentatively referred to the family Eobaataridae, though it probably is not a member.
Dakotamys is a genus of extinct mammal that lived during the Upper Cretaceous. It shared the world with dinosaurs. This small creature was a member of the also extinct order Multituberculata within the suborder Cimolodonta and was a member of the Paracimexomys group.
Sloanbaatar is a mammal genus that lived in Mongolia during the Upper Cretaceous. It lived at the same time as the dinosaurs. This animal was a member of the also extinct order Multituberculata within the suborder Cimolodonta and the family Sloanbaataridae.
Nessovbaatar is a genus of extinct mammal from the Upper Cretaceous of Mongolia. It eked out its living in the company of Central Asian dinosaurs. This animal was a member of the extinct order Multituberculata within the suborder Cimolodonta and family Sloanbaataridae.
Bulganbaatar is a Central Asian mammal genus from the Upper Cretaceous. It existed in the company of dinosaurs. This animal was a member of the extinct order Multituberculata. It's within the suborder Cimolodonta and is a member of the superfamily Djadochtatherioidea. The genus Bulganbaatar was named by Kielan-Jaworowska Z. in 1974.
Buginbaatar is an extinct genus of mammal from the Upper Cretaceous of Mongolia. It is a member of the extinct order Multituberculata, within the suborder Cimolodonta and family Cimolomyidae. It lived towards the end of the Mesozoic era.
Uzbekbaatar is a genus of extinct mammal from the Upper Cretaceous of Uzbekistan. It was a member of the extinct order Multituberculata within the suborder Cimolodonta, though its further affinities are unclear. The genus was named by Kielan-Jaworowska Z. and Nesov L.A. in 1992 and means "Uzbek hero".
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.
Echinodon is a genus of heterodontosaurid dinosaur that lived during the earliest Cretaceous of southern England and possibly western France in the Berriasian epoch. The first specimens were jaw bones named Echinodon becklesii by Sir Richard Owen in 1861, and since their original description only additional teeth have been discovered. The specific name honours collector Samuel Beckles who discovered the material of Echinodon and many other taxa from across England, while the genus name translates as "prickly tooth" in reference to the dental anatomy of the taxon.
Zofia Kielan-Jaworowska was a Polish paleobiologist. In the mid-1960s, she led a series of Polish-Mongolian paleontological expeditions to the Gobi Desert. She was the first woman to serve on the executive committee of the International Union of Geological Sciences.
