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'' ** Gen ...

Deseadan
The Deseadan ( es, Deseadense) 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. Formations Fossils Correlations The Deseadan South American land mammal age (SALMA) is equivalent to the Arikareean in the North American land mammal age (NALMA) and the Harrisonian in the 2000 version of the classification. It overlaps with the Hsandagolian The Hsandagolian age is a period of geologic time (33.9 – 23.03 Ma) within the Oligocene epoch of the Paleogene used more specifically with Asian Land Mammal Ages.

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. The taxonomy of the genus has historically been confused, with some authors applying the name ''M. acouchy'' to the green acouchi, in which case the red acouchi is called ''M. exilis''. Although this issue has now been resolved, other problems remain; in particular, the green acouchi may include more than one species. They are coloured brown or greenish, but with bright orange or red parts on their heads. Often, acouchis live in riverbanks, where they dig holes. Like the common agoutis, but un ...

Distribution It is native to northeastern South America, where found in Venezuela, Guyana, Suriname, French Guiana, northeastern Brazil, Trinidad and Tobago and Saint Lucia in the Caribbean. It has also been introduced to 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 t ...

Azara's Agouti
Azara's agouti (''Dasyprocta azarae'') is an agouti species from the family Dasyproctidae. Found in Brazil, Paraguay, and Argentina, it is named after Spanish naturalist Félix de Azara Félix Manuel de Azara y Perera (18 May 1746 – 20 October 1821) was a Spanish military officer, naturalist, and engineer. Life Félix de Azara was born on 18 May 1746 in Barbunales, Aragon. He joined the army and attended a Spanish military .... 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 out ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Agouti
The agouti (, ) or common agouti is any of several rodent species of the genus ''Dasyprocta''. They are native to Middle America, northern and central South America, and the southern Lesser Antilles. Some species have also been introduced elsewhere in the West Indies. They are related to guinea pigs and look quite similar, but they are larger and have longer legs. The species vary considerably in colour, being brown, reddish, dull orange, greyish, or blackish, but typically with lighter underparts. Their bodies are covered with coarse hair, which is raised when alarmed. They weigh and are in length, with short, hairless tails. The related pacas were placed by some authorities in a genus called ''Agouti'', though ''Cuniculus'' has priority and is the correct term. In West Africa (especially Ivory Coast), the name "agouti" designates the greater cane rat which, while an agricultural pest, is often sought as a bushmeat delicacy. The Spanish term is ''agutí.''
