Mammals
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Saur ...

Drymoreomys
''Drymoreomys'' is a rodent genus in the tribe Oryzomyini that lives in the Atlantic Forest of Brazil. The single species, ''D. albimaculatus'', is known only from the states of São Paulo and Santa Catarina and was not named until 2011. It lives in the humid forest on the eastern slopes of the Serra do Mar and perhaps reproduces year-round. Although its range is relatively large and includes some protected areas, it is patchy and threatened, and the discoverers recommend that the animal be considered "Near Threatened" on the IUCN Red List. Within Oryzomyini, ''Drymoreomys'' appears to be most closely related to ''Eremoryzomys'' from the Andes of Peru, a biogeographically unusual relationship, in that the two populations are widely separated and each is adapted to an arid or a moist environment. With a body mass of , ''Drymoreomys'' is a medium-sized rodent with long fur that is orange to reddish-buff above and grayish with several white patches below. The pads on the hind ...

Chacodelphys
The Chacoan pygmy opossum (''Chacodelphys formosa'') is a recently described genus and species of didelphimorph marsupial. The only species in ''Chacodelphys'', ''C. formosa'', was known until 2004 from only one specimen collected in 1920 in the Chaco of Formosa Province, Argentina. The species is gaining popularity as a pocket pet. Description The Chacoan pygmy opossum is the smallest known species of didelphid. It has a head-body length of 68 mm, a tail of 55 mm and a hind foot of 11. It differs from the other " marmosine" genera (''Marmosa'', ''Monodelphis'', ''Thylamys'', '' Tlacuatzin'', ''Gracilinanus'', ''Marmosops'', '' Lestodelphys'') in having a long third manual digit, no distinctly tricolored pelage Fur is a thick growth of hair that covers the skin of mammals. It consists of a combination of oily #Guard hair, guard hair on top and thick #Down hair, underfur beneath. The guard hair keeps moisture from reaching the skin; the underfur acts as ..., a long ...

Sommeromys
Sommer's Sulawesi rat (''Sommeromys macrorhinos'') is a species of rodent in the family Muridae from Sulawesi. It is the only species in the monotypic genus ''Sommeromys'' and was described by Musser & Durden in 2002. Distribution ''S. macrorhinos'' is known from only one specimen, AMNH 226956 (American Museum of Natural History, catalogue number 226956). This specimen was caught at 2400 m above sea level on Gunung Tokala, a mountain between the Rampi and Seko valleys in the province of Sulawesi Tengah, in primary mossy forest which was somewhat disturbed by human activities. The describers expected that the genus also occurs in other high montane forests of Sulawesi. It is also found on Mount Gandangdewata, West Sulawesi. Discovery On the first of August, 1973, the NAMRU team that would discover ''S. macrorhinos'' reached Gunung Tokala. Despite a heavy, cold rain, someone set some Victor rat traps and found one specimen each of '' Tateomys rhinogradoides'' and ''S. macrorhi ...

Handleyomys
''Handleyomys'' is a genus of Central and South American rodents in the tribe Oryzomyini of family Cricetidae. It was first described in 2002 to include two species from the Colombian Andes which were previously included in distinct and unrelated genera, ''Aepeomys'' and ''Oryzomys'', but which turned out to be closely related. Later, in 2006, six other species were provisionally added from ''Oryzomys''; these are expected to be placed in new genera in the future. The genus now includes the following species: *'' Handleyomys alfaroi'' *'' Handleyomys chapmani'' *'' Handleyomys fuscatus'' *'' Handleyomys intectus'' *''Handleyomys melanotis ''Handleyomys melanotis'', also known as the black-eared oryzomysMusser and Carleton, 2005 or black-eared rice rat, is a species of rodent in the genus ''Handleyomys'' of family Cricetidae.

Hyladelphys
Kalinowski's mouse opossum or the Peru gracile mouse opossum (''Hyladelphys kalinowskii'') is a species of opossum in the family Didelphidae. It is found in Brazil, French Guiana, Guyana, and Peru. Its natural habitat is subtropical or tropical moist lowland forests at elevations up to 1000 m. This is the only living species in the genus ''Hyladelphys''. It was removed from the genus ''Gracilinanus ''Gracilinanus'' is a genus of opossum in the family Didelphidae.

Tapecomys
The primordial tapecua (''Tapecomys primus'') is a species of medium-sized rodent in the family Cricetidae. The type locality is in southeastern Bolivia. It is the only known species of the genus ''Tapecomys''. Two specimens were found in 1991 in a forested region at an elevation of 1500 m near the village of Tapecua in the Tarija Department of Bolivia. A few additional specimens have been found since, from the type locality and from a location in Jujuy Province, northern Argentina.

Salinoctomys
The Chalchalero viscacha rat or Chalchalero vizcacha rat (''Tympanoctomys loschalchalerosorum'') is a species of caviomorph rodent in the family Octodontidae. It was formerly considered to be monotypic within the genus ''Salinoctomys'', but has been shown by genetic analysis to nest within ''Tympanoctomys'', and in particular, within the variation of '' T. barrerae''. The species is endemic to a small area of northwestern Argentina, where it lives in shrublands bordering the salt flats of the Salinas Grandes. Its diet consists of halophyte plants. It is named after an Argentine musical group, Los Chalchaleros, whose songs were popular with its discoverers. Description The Chalchalero viscacha rat is a medium-sized species of rat. Its dorsal fur is dark brownish black while its underparts are white. The hairs on its back are about long and have a grey base, a brown band and a black tip, and the guard hairs are a uniform darkish brown. This viscacha rat reaches a head-and-body l ...

Pipanacoctomys
The golden viscacha rat or golden vizcacha rat (''Pipanacoctomys aureus'') is the single species of the genus ''Pipanacoctomys'' of the rodent family Octodontidae. It has 92 chromosomes and has been regarded as tetraploid ( 4x = 2n).Gallardo, M. H. ''et al.'' (2004).Whole-genome duplications in South American desert rodents (Octodontidae). ''Biological Journal of the Linnean Society, 82'', 443-451. This octodontid and its sister-species, the plains viscacha rat (''Tympanoctomys barrerae'') (2n = 102), may have arisen from the diploid mountain viscacha rat (''Octomys mimax''), (2x = 2n = 56) as a result of the doubling and subsequent loss of some chromosomes. However, some genetic studies have rejected any polyploidism in mammals as unlikely, and suggest that amplification and dispersion of repetitive sequences best explain the large genome size. Description The golden viscacha rat grows to a head-and-body length of about with a tufted tail of about . The dorsal fur is golden-bl ...
