Agoutinae
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 ...

Oligocene
The Oligocene ( ) is a geologic epoch of the Paleogene Period and extends from about 33.9 million to 23 million years before the present ( to ). As with other older geologic periods, the rock beds that define the epoch are well identified but the exact dates of the start and end of the epoch are slightly uncertain. The name Oligocene was coined in 1854 by the German paleontologist Heinrich Ernst Beyrich from his studies of marine beds in Belgium and Germany. The name comes from the Ancient Greek (''olígos'', "few") and (''kainós'', "new"), and refers to the sparsity of extant forms of molluscs. The Oligocene is preceded by the Eocene Epoch and is followed by the Miocene Epoch. The Oligocene is the third and final epoch of the Paleogene Period. The Oligocene is often considered an important time of transition, a link between the archaic world of the tropical Eocene and the more modern ecosystems of the Miocene. Major changes during the Oligocene included a global expansion o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australoprocta
''Australoprocta'' is an extinct genus of dasyproctid rodent that lived during the Early Miocene of what is now Argentina.

Mexican Agouti
The Mexican agouti (''Dasyprocta mexicana''), also known as the Mexican black agouti, is a species of rodent in the family Dasyproctidae. It is native to lowland evergreen forest and second growth in southern Mexico (Veracruz, Oaxaca, Chiapas and Tabasco), but has also been introduced to Cuba. This critically endangered species is threatened by habitat loss. Its overall blackish color separates it from the only other agouti found in Mexico, the Central American agouti The Central American agouti (''Dasyprocta punctata'') is a species of agouti from the family Dasyproctidae. The main portion of its range is from Chiapas and the Yucatan Peninsula (southern Mexico), through Central America, to northwestern Ecuad ....

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, 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 ...

Black Agouti
The black agouti (''Dasyprocta fuliginosa'') is a South American species of agouti from the family Dasyproctidae. Distribution and habitat It is found in the northwestern Amazon in southern Venezuela, eastern Colombia, eastern Ecuador, western Brazil and northeastern Peru.

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] |
