The Tsaganomyidae are an extinct family of rodents from Asia. It contains three genera. [1] Tsaganomyids are generally considered to be related to the Hystricognathi (porcupines and relatives). [2] Members of Tsaganomyidae were fossorial (digging) rodents that probably used their incisor teeth to dig like some living mole rats. [3]

Characteristics

Tsaganomyids had a protrogomorphous zygomasseteric system, a hystricognathous lower jaw, and multiserial enamel in their incisor teeth. [3]

Dasyproctidae Family of rodents

Dasyproctidae is a family of large South American rodents, comprising the agoutis and acouchis. Their fur is a reddish or dark colour above, with a paler underside. They are herbivorous, often feeding on ripe fruit that falls from trees. They live in burrows, and, like squirrels, will bury some of their food for later use.

Simplicidentata Group of mammals

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.

Diatomyidae Family of rodents

Diatomyidae is a family of hystricomorph rodents. It is represented by a single living species, Laonastes aenigmamus, native to Laos in Southeast Asia. Fossil species are known from the Oligocene and Miocene of Asia and eastern Europe.

Cerradomys marinhus, also known as Marinho's rice rat, is a rodent species from South America. It is found in Minas Gerais, Brazil. It was formerly known as Oryzomys marinhus, but was transferred to the new genus Cerradomys in 2006.

Cerradomys subflavus, also known as the terraced rice rat or flavescent oryzomys, is a rodent species from South America in the genus Cerradomys. It is found in the states of Goiás, São Paulo, and Minas Gerais, Brazil. Populations in Bolivia, Paraguay, and elsewhere in Brazil that were previously placed in this species are now classified as various other species of Cerradomys.

Eurymylidae is a family of extinct simplicidentates. Most authorities consider them to be basal to all modern rodents and may have been the ancestral stock whence the most recent common ancestor of all modern rodents arose. However, the more completely known eurymylids, including Eurymylus, Heomys, Matutinia, and Rhombomylus, appear to represent a monophyletic side branch not directly ancestral to rodents. Huang et al. (2004) have argued that Hanomys, Matutinia, and Rhombomylus form a clade characterized by distinctive features of the skull and dentition that should be recognized as a separate family, Rhombomylidae. Eurymylids are only known from Asia.

<i>Tsaganomys</i> Extinct genus of rodents

Tsaganomys altaicus is an extinct species of rodent from Asia, and the only species in the genus Tsaganomys.

Hapalodectidae Extinct family of mammals

Hapalodectidae is an extinct family of relatively small-bodied mesonychian placental mammals from the Paleocene and Eocene of North America and Asia. Hapalodectids differ from the larger and better-known mesonychids by having teeth specialized for cutting, while the teeth of other mesonychids, such as Mesonyx or Sinonyx, are more specialized for crushing bones. Hapalodectids were once considered a subfamily of the Mesonychidae, but the discovery of a skull of Hapalodectes hetangensis showed additional differences justifying placement in a distinct family. In particular, H. hetangensis has a postorbital bar closing the back of the orbit, a feature lacking in mesonychids. The skeleton of hapalodectids is poorly known, and of the postcranial elements, only the humerus has been described. The morphology of this bone indicates less specialization for terrestrial locomotion than in mesonychids.

<i>Noronhomys</i> Extinct rat species from the islands of Fernando de Noronha off northeastern Brazil

Noronhomys vespuccii, also known as Vespucci's rodent, is an extinct rat species from the islands of Fernando de Noronha off northeastern Brazil. Italian explorer Amerigo Vespucci may have seen it on a visit to Fernando de Noronha in 1503, but it subsequently became extinct, perhaps because of the exotic rats and mice introduced by the first explorers of the island. Numerous but fragmentary fossil remains of the animal, of uncertain but probably Holocene age, were discovered in 1973 and described in 1999.

Cerradomys maracajuensis, also known as the Maracaju oryzomys, is a rodent species from South America. It is terrestrial and is found in gallery forests in Bolivia, Paraguay and nearby Brazil and Peru. It was first discovered near the Brazilian city of Maracaju.

<i>Ysengrinia</i> Extinct genus of mammals known as bear dogs

Ysengrinia is an extinct genus of bear dogs found in Europe and North America, and possibly in southwestern Africa, during the Early Miocene.

Hylaeamys acritus, formerly Oryzomys acritus, is an oryzomyine rodent of the family Cricetidae. The name is derived from the Greek word ακριτος 'confused, doubtful', because it could easily be confused with species such as H. megacephalus and Euryoryzomys nitidus. It is known only from northeastern Bolivia; its type locality is within Noel Kempff Mercado National Park. The rodent is terrestrial and is found in moist lowland semideciduous forest and savanna. It has olive brown coloration on its back; the cheeks and flanks are amber, and the top of the head is dark. The coat is 9 mm long at the center of the torso. Chest fur between the front legs is thick and 3 to 4 mm long. Abdominal hairs are gray at the base and white at the top.

In anatomy, posterolateral palatal pits are gaps at the sides of the back of the bony palate, near the last molars. Posterolateral palatal pits are present, in various degrees of development, in several members of the rodent family Cricetidae. Many members of the family lack them or have only simple pits, but Arvicolinae and Oryzomyini have more highly developed posterolateral palatal pits. Posterolateral palatal pits are also present in some other rodents, including Glis, Jaculus, Hystrix, Abrocoma, Ctenomys, Chinchilla, and Lagidium.

Zygomatic plate

In rodent anatomy, the zygomatic plate is a bony plate derived from the flattened front part of the zygomatic arch (cheekbone). At the back, it connects to the front (maxillary) root of the zygomatic arch, and at the top it is connected to the rest of the skull via the antorbital bridge. It is part of the maxillary bone, or upper jaw, which also contains the upper cheekteeth. Primitively, rodents have a nearly horizontal zygomatic plate. In association with specializations in zygomasseteric system, several distinct morphologies have developed across the order.

Brontotheriidae Extinct family of odd-toed ungulates

Brontotheriidae is a family of extinct mammals belonging to the order Perissodactyla, the order that includes horses, rhinoceroses, and tapirs. Superficially, they looked rather like rhinos, although they were actually more closely related to horses; Equidae and Brontotheriidae make up the suborder Hippomorpha. They lived around 56–34 million years ago, until the very close of the Eocene.

<i>Saxatilomys</i> Genus of rodents

Saxatilomys paulinae is a species of murid rodent native to central Laos and Vietnam, separated to a monotypic genus Saxatilomys. It was first discovered in the Khammouan Limestone National Biodiversity Conservation Area in Khammouan Province, Laos, and also been found in the Vietnamese province of Quang Bình. It is the only known species in the genus Saxatilomys. The genus name is derived from the Latin saxatilis, meaning "among the rocks" and the Greek mys, meaning mouse or rat.
