A hopping mouse is any of about ten different Australian native mice in the genus Notomys. They are rodents, not marsupials, and their ancestors are thought to have arrived from Asia about 5 million years ago.
Myocastor is a genus of rodent that contains the living nutria, as well as several fossil species.
Eutamias is a genus of chipmunks within the tribe Marmotini of the squirrel family. It includes a single living species, the Siberian chipmunk. The genus is often treated as a subgenus of Tamias, which is now restricted to the eastern chipmunk of North America. Neotamias, which now includes the western North American chipmunks, has also been included in Eutamias.
Simplicidentata is a group of mammals that includes the rodents and their closest extinct relatives. The term has historically been used as an alternative to Rodentia, contrasting the rodents with their close relatives the lagomorphs. However, Simplicidentata is now defined as including all members of Glires that share a more recent common ancestor with living rodents than with living lagomorphs. Thus, Simplicidentata is a total group that is more inclusive than Rodentia, a crown group that includes all living rodents, their last common ancestor, and all its descendants. Under this definition, the loss of the second pair of upper incisors is a synapomorphic feature of Simplicidentata. The loss of the second upper premolar (P2) has also been considered as synapomorphic for Simplicidentata, but the primitive simplicidentate Sinomylus does have a P2.
A kangaroo mouse is either one of the two species of jumping mouse native to the deserts of the southwestern United States, predominantly found in the state of Nevada. The name "kangaroo mouse" refers to the species' extraordinary jumping ability, as well as its habit of bipedal locomotion. The two species are:
Zapodidae, the jumping mice, is a family of mouse-like rodents in North America and China.
Dipodoidea is a superfamily of rodents, also known as dipodoids, found across the Northern Hemisphere. This superfamily includes over 50 species among the 16 genera in 3 families. They include the jerboas, jumping mice, and birch mice. Different species are found in grassland, deserts, and forests. They are all capable of saltation, a feature that is most highly evolved in the desert-dwelling jerboas.
Hyaenodon ("hyena-tooth") is an extinct genus of carnivorous placental mammals from extinct tribe Hyaenodontini within extinct subfamily Hyaenodontinae, that lived in Eurasia and North America from the middle Eocene, throughout the Oligocene, to the early Miocene.
Kozlov's pygmy jerboa is a species of rodent in the family Dipodidae. It is found in northwestern China and southern and eastern Mongolia. Its natural habitat is temperate desert.
Gobiomyidae is a small extinct family of rodents from the Eocene of Asia. The family contains four genera and belongs to the superfamily Ctenodactyloidea, which also contains the living Laotian rock rat and gundis and their fossil relatives. When Wang named the family, gobiomyids were considered the closest known relatives of Ctenodactylidae, but newer research indicates that Diatomyidae is more closely related to living ctenodactylids.
Sinemys is an extinct genus of turtle from the Late Jurassic to Early Cretaceous of China. Three species have been named: S. lens, the type species, from the Kimmeridgian-Tithonian of Shandong; S. gamera, from the Valanginian-Albian of Nei Mongol, and S. brevispinus from Early Cretaceous of Nei Mongol. S. wuerhoensis, from the Aptian-Albian of Xinjiang, is not referrable to this genus. Indeterminate specimen that may be belong to this genus is also known from Japan. The species S. gamera is noted for the presence of a pair of elongate spines projecting outwards and backwards from seventh costal of the carapace. These may have served a hydrodynamic function.
The Irdin Manha Formation is a geological formation from the Eocene located in Inner Mongolia, China, a few kilometres south of the Mongolian border.
Ageitonomys neimongolensis is an extinct species of rodent which existed in Alxa Left Banner, Inner Mongolia, China during the early Oligocene period. It was first named by Wang Ban-Yue in 2010.
Erlianomys combinatus is an extinct species of myodont rodent which existed in Inner Mongolia, China, during the early Eocene period.
Omoiosicista is an extinct genus of dipodid rodent which existed in central Nei Mongol, China, during the early Miocene. It was first named by Yuri Kimura in 2010 and the type species is Omoiosicista fui.
