Reigomys
''Reigomys primigenus'' is an extinct oryzomyine rodent known from Pleistocene deposits in Tarija Department, southeastern Bolivia. It is known from a number of isolated jaws and molars which show that its molars were almost identical to those of the living ''Lundomys''. On the other hand, the animal possesses a number of derived traits of the palate which document a closer relationship to living ''Holochilus'', the genus of South American marsh rats, and for this reason it was placed in the genus ''Holochilus'' when it was first described in 1996. The subsequent discoveries of ''Noronhomys'' and ''Carletonomys'', which may be more closely related to extant ''Holochilus'' than ''H. primigenus'' is, have cast its placement in ''Holochilus'' into doubt, and it was ultimately made the type species of a separate genus, ''Reigomys''. Taxonomy Material of ''Reigomys primigenus'' was collected in 1924 and 1927 by Elmer Riggs of the Field Museum of Natural History, but the animal ...

Oryzomyini
Oryzomyini is a tribe of rodents in the subfamily Sigmodontinae of the family Cricetidae. It includes about 120 species in about thirty genera,Weksler et al., 2006, table 1 distributed from the eastern United States to the southernmost parts of South America, including many offshore islands. It is part of the clade Oryzomyalia, which includes most of the South American Sigmodontinae. The name ''Oryzomyini'' derives from that of its type genus, ''Oryzomys'', which means "rice rat" or "rice mouse". Many species are also known as rice rats. Taxonomy Contents of Oryzomyini An oryzomyine group was first envisaged by Oldfield Thomas in the early 20th century. He defined it to include pentalophodont species, which have a mesoloph(id) on the upper and lower molars, with a long palate (extending past the third molars). Thomas included ''Oligoryzomys'', ''Oecomys'', and ''Oryzomys'' (which included many species now in other genera), as well as '' Rhagomys'', which is currently classified ...

Holochilus Sciureus
The Amazonian marsh rat (''Holochilus sciureus''), also known as the common marsh rat,Duff, A. and Lawson, A. 2004. ''Mammals of the World: A checklist''. Yale University Press, 312 pp. or simply the marsh rat, is a rodent species from South America. Description Amazonian marsh rats are smaller than the common brown rat, but otherwise have a similar appearance. They range from in head-body length, with a tail long, and typically weigh between . They have short fur, which is tawny or buff over the back, becomes paler on the flanks, and fades to white or pale orange on the underparts. The hindfeet are noticeably larger than the forepaws, with prominent claws and partial webbing between the toes. There is also a slight fringe of longer, silvery, hair, around the soles of the feet. Females have eight or ten teats. Distribution and habitat Amazonian marsh rats are found across much of northern South America east of the Andes. They inhabit open areas such as grasslands, savanna, mar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

There are 300 mammal species in Bolivia, of which two are critically endangered, five are endangered, seventeen are vulnerable, and twelve are near threatened. The following tags are used to highlight each species' conservation status as assessed by the International Union for Conservation of Nature: Some species were assessed using an earlier set of criteria. Species assessed using this system have the following instead of near threatened and least concern categories: Subclass: Theria Infraclass: Eutheria Order: Cingulata (armadillos) ---- The armadillos are small mammals with a bony armored shell.

Rodent
Rodents (from Latin , 'to gnaw') 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. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose i ...
