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.
Arginbaatar is a genus of extinct mammal from the Lower Cretaceous of Mongolia. It was a member of the Multituberculata, an order which is also extinct. It belongs to the family Arginbaataridae. The genus Arginbaatar was named by Trofimov B.A. in 1980. "Argin" is in reference to Argin-gol River, Aryaykher aymak, Gobi Desert, Mongolia, near where the fossils were found. Baatar is Mongolian for "hero" or "warrior."
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.
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.
Djadochtatherioidea is a group of extinct mammals known from the upper Cretaceous of Central Asia. They were members of an also extinct order called Multituberculata. These were generally somewhat rodent-like creatures, who scurried around during the "age of the dinosaurs", though nonetheless very ecologically diverse; several were jerboa-like hoppers, while others like Mangasbaatar were large sized and fossorial. Unusually for multituberculates, some of this group are represented by very good remains. All upper Cretaceous Mongolian multituberculates are included with one exception, the genus Buginbaatar.
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.
Kamptobaatar is a Mongolian mammal genus from the Upper Cretaceous. It lived at the same time as the later dinosaurs. This animal was a member of the extinct order Multituberculata within the suborder Cimolodonta and 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.
Chulsanbaatar is a genus of mammal from the Cretaceous of Mongolia. It lived during the Mesozoic, also known as the "age of the dinosaurs." This small creature was a member of the extinct order of Multituberculata and is within the suborder Cimolodonta. The genus Chulsanbaatar was named by Kielan-Jaworowska Z. in 1974.
Nemegtbaatar is a genus of mammal from the Upper Cretaceous Period of what is now Mongolia. It existed in the company of much larger dinosaurs, found together in the Nemegt Basin. This creature was a member of the extinct order Multituberculata. It is within the suborder Cimolodonta and is a member of the superfamily Djadochtatherioidea. It was a hopping, gerboa-like species.
Djadochtatheriidae is a family of fossil mammals within the extinct order Multituberculata. Remains are known from the Upper Cretaceous of Central Asia. These animals lived during the Mesozoic, also known as the "age of the dinosaurs". This family is part of the suborder of Cimolodonta. The taxon Djadochtatheriidae was named by Z. Kielan-Jaworowska and J. H. Hurum in 1997.
Catopsbaatar is a genus of multituberculate, an extinct order of rodent-like mammals. It lived in what is now Mongolia during the late Campanian age of the Late Cretaceous epoch, about 72 million years ago. The first fossils were collected in the early 1970s, and the animal was named as a new species of the genus Djadochtatherium in 1974, D. catopsaloides. The specific name refers to the animal's similarity to the genus Catopsalis. The species was moved to the genus Catopsalis in 1979, and received its own genus in 1994. Five skulls, one molar, and one skeleton with a skull are known; the last is the genus' most complete specimen. Catopsbaatar was a member of the family Djadochtatheriidae.
Kryptobaatarand also known as Gobibaatar or Tugrigbaatar is an extinct mammalian genus dating from the Upper Cretaceous Period and identified in Central Asia. This animal was a member of the extinct order of Multituberculata within the suborder Cimolodonta, and was a member of the family Djadochtatheriidae. It lived contemporaneously with some of the dinosaurs. Its skull had a length of perhaps 3 cm.
Tombaatar is a mammal genus that existed during the Mongolian Upper Cretaceous period. It co-existed with some of the late dinosaurs. This animal was a member of the extinct order Multituberculata, within the suborder Cimolodonta and family Djadochtatheriidae. The genus Tombaatar was named by Rougier G.W., Novacek M. and Dashzeveg D. in 1997.
Cimolomyidae is a family of fossil mammal within the extinct order Multituberculata. Representatives are known from the Upper Cretaceous and the Paleocene of North America and perhaps Mongolia. The family is part of the suborder Cimolodonta. Other than that, their systematic relationships are hard to define. Some authors have placed the taxon within Taeniolabidoidea. Kielan-Jaworowska and Hurum (2001) expressly don't.
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.
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.
