Dasyproctidae
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 herbivore, 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. Dasyproctids exist in Central and South America, which are the tropical parts of the New World. The fossil record of this family can be traced back to the Late Oligocene (Deseadan in the South American land mammal age, SALMA classification). As with all rodents, members of this family have incisors, pre-molars, and molars, but no canines. The cheek teeth are hypsodonty, hypsodont and flat-crowned. Classification Fossil taxa follow McKenna and Bell, with modifications following Kramarz. * Family Dasyproctidae ** Genus †''Alloiomys'' ** Genus †''Australoprocta'' ** Genus †''Branisamys'' ** Genus †''Incamys'' ** Genus †''Neoreomys'' ** G ...

Mexican Agouti
The Mexican agouti, (''Dasyprocta mexicana)'', also known as the Mexican black agouti, is a species of rodent in the genus '' Dasyprocta''. This species was first discovered in 1860 in Veracruz, Mexico and described by Henri Louis Frédéric de Saussure. Physical description ''Dasyprocta mexicana'' is a medium-sized rodent, weighing between 2 kilograms to 4 kilograms as an adult. This length of ''D. mexicana'' ranges from 40 centimeters to 60 centimeters, which is inclusive of the tail that ranges from 2 centimeters to 3 centimeters in length and is located at the most posterior point of the body.Don E. Wilson, Thomas E. Lacher, Jr & Russell A. Mittermeier, 2016, Dasyproctidae, Handbook of the Mammals of the World – Volume 6 Lagomorphs and Rodents I, Barcelona: Lynx Edicions, pp. 440-461 : 457 While data is limited on the height of this particular species, it is expected to be similar to the average height of 23 centimeters seen in similar sized agoutis.

Deseadan
The Deseadan () age is a period of geologic time (29.0–21.0 Ma) within the Oligocene epoch of the Paleogene to the Early Miocene epoch of the Neogene, used more specifically within the SALMA classification of South America. It follows the Tinguirirican and precedes the Colhuehuapian age. Etymology The age is named after the Deseado Formation of the Deseado Massif in eastern Patagonia, Argentina.

Acouchi
The acouchis (genus ''Myoprocta'') are rodents belonging to the family Dasyproctidae from the Amazon basin. They are generally smaller than agoutis and have very short tails (5 to 7 cm), while agoutis lack tails. For this reason the acouchis are also called tailed agoutis. The two species – the red acouchi (''M. acouchy'') in the Guianas of Amazonia and nearby parts of Brazil, and the green acouchi (''M. pratti'') in western Amazonia - differ in coloration and other characteristics.

Red-rumped Agouti
The red-rumped agouti (''Dasyprocta leporina''), also known as the golden-rumped agouti, orange-rumped agouti or Brazilian agouti, is a species of agouti from the family Dasyproctidae. Distribution It is native to northeastern South America, mainly in Venezuela, Guyana, Suriname, French Guiana, northeastern Brazil, Trinidad and Tobago and Saint Lucia in the Caribbean. It has also been introduced to Florida, the U.S. Virgin Islands, Grenada, and Dominica. Names Despite the alternative name Brazilian agouti, it is neither the only nor the most widespread species of agouti in Brazil. In Brazil all agoutis are often called "cutia" . Habitat It is found in a wide range of forests, including rainforest and secondary forest. Description Red-rumped agoutis weigh about . They are about long. The females are larger than males but otherwise look similar. They are brownish with darker spots on the upper body. The fur becomes more orange as it goes past (going down) the middle area of ...

Azara's Agouti
Azara's agouti (''Dasyprocta azarae'') is an agouti species from the family Dasyproctidae 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 herbivore, herbivorous, often feeding on ripe fruit that falls from tree .... Found in Brazil, Paraguay, and Argentina, it is named after Spanish naturalist Félix de Azara. The population is unknown and may have gone locally extinct in some areas due to hunting; it is listed as vulnerable in Argentina. Behaviour Despite being active during the day, Azara's agoutis are quite difficult to study, as they are naturally extremely shy and will flee and hide when humans approach. Their shyness may be related to their solitary lifestyles, but may be because they are heavily preyed upon by many carnivorous species, including humans. However, if bred in captivity, they can become trusting animals. Azara's agoutis will let ou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
