Anomalomyidae is a family of extinct muroid rodents from Europe. [1]
The pacarana is a rare and slow-moving hystricognath rodent indigenous to South America. Native Tupi people call it the pacarana because it is superficially similar to the paca, a different rodent which is not in the same family. The pacarana has a chunky body and is large for a rodent, weighing up to 15 kg (33 lb) and measuring up to 79 cm in length, not including the thick, furry tail.
The fat-tailed gerbil, also called the duprasi gerbil or doop, is a rodent belonging to the subfamily Gerbillinae. It is only species in the genus Pachyuromys. They are frequently kept as pets.
Owl's spiny rat is a rodent species in the family Echimyidae found in Brazil. It is the only species in the genus Carterodon. Owl's spiny rat has evolved characteristics such as a heightened ability to dig in open grasslands during times of environmental change.
The giant tree-rat is a species in the family Echimyidae, the spiny rats. It is the only species in the monotypic genus Toromys. It is endemic to Brazil, where it occurs in the flooded forest along the banks of the Amazon River and its tributaries.
Armintomys is an extinct genus of rodent from North America related to jerboas and jumping mice. It is the only genus in the family Armintomyidae. It lived during the early Eocene, and is the oldest known example of a hystricomorphous zygomasseteric dentition. In addition, Armintomys is also the oldest known rodent that had an incisor enamel transition from pauciserial to uniserial. Its remains have only been found in the Wind River Basin in Wyoming, and could be found there during the species' existence on Earth. It was previously assumed that Armintomys belonged to the Dipodoidea family, but has since been understood to have been part of an early radiation of dipodoid rodents, but was not directly ancestral to any later dipodoids, thus it was recategorized into its own family.
Ailuravus is a genus of prehistoric rodents in the family Ischyromyidae.
Mesomys is a genus of South American spiny rats in the family Echimyidae.
The Panay cloudrunner is the second-largest cloud rat, a squirrel-like rodent that is found on the island of Panay in the Philippines. It is the most endangered rodent species in Panay, and one of the only few known cloud rat species in the world.
Dactylomys is the genus of South American bamboo rats They are arboreal members of the family Echimyidae.
Euryzygomatomys is a genus of South American rodents, commonly called guiaras, in the family Echimyidae. It contains two extant and one fossil species, found in Argentina, Brazil and Paraguay. They are as follows:
The North African gerbil is a species of rodent in the family Muridae. It is found in North Africa where its natural habitats are arable land and rocky areas of the Maghreb, and hot Saharan deserts.
Shaw's jird is a species of rodent in the family Muridae. It is found in Algeria, Egypt, Libya, Morocco, and Tunisia. Its natural habitats are arable land, pastureland, and rural gardens.
Diplomys is a genus of rodent in the family Echimyidae. They are found in Costa Rica, Ecuador, Colombia and Panama.
Makalata is a genus of rodents in the family Echimyidae.
Mesocapromys is a genus of rodent in the subfamily Capromyinae. The genus is restricted to Cuba and associated islands.
Plagiodontia is a genus of rodent in the subfamily Capromyinae (hutias). All known species are endemic to the Caribbean island of Hispaniola.
Rodents are mammals of the order Rodentia, which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity.
Thrichomys is a genus of South American rodents in the family Echimyidae. It contains at least five species, found in Bolivia, Brazil and Paraguay. They are as follows:
Echimyidae is the family of neotropical spiny rats and their fossil relatives. This is the most species-rich family of hystricognath rodents. It is probably also the most ecologically diverse, with members ranging from fully arboreal to terrestrial to fossorial to semiaquatic habits. They presently exist mainly in South America; three members of the family also range into Central America, and the hutias are found in the Greater Antilles in the Caribbean. Species of the extinct subfamily Heteropsomyinae formerly lived on Cuba, Hispaniola, and Puerto Rico in the Antilles, probably until the arrival of Europeans.
Myocastorini is a tribe of echimyid rodents, proposed in 2017, and containing the five extant genera Callistomys, Hoplomys, Myocastor, Proechimys, and Thrichomys.
