Speothos
''Speothos'' is a genus of canid found in Central and South America. The genus includes the living bush dog, ''Speothos venaticus'', and an extinct Pleistocene species, ''Speothos pacivorus''. Unusually, the fossil species was identified and named before the extant species was discovered, with the result that the type species of ''Speothos'' is ''S. pacivorus''. S. Pacivorus had a larger overall body size and a double-rooted second lower molar. It has been proposed that ''Speothos'' originated in the Brazilian highlands sometime during the Pleistocene. The paleobiogeography and evolutionary relationships of ''Speothos'' and other South American canids is unclear. Morphological data suggest that ''Speothos'' is most closely related to another small canid, ''Atelocynus'' (short eared dog). The skulls of both ''Speothos'' and ''Atelocynus'' have short nasals that terminate rostral to the maxillary-frontal suture, a character shared with ''Vulpes'' (fox genus). ''Speothos'' and ''Ate ...

Bush Dog
The bush dog (''Speothos venaticus'') is a canine found in Central and South America. In spite of its extensive range, it is very rare in most areas except in Suriname, Guyana and Peru; it was first identified by Peter Wilhelm Lund from fossils in Brazilian caves and was believed to be extinct. The bush dog is the only living species in the genus ''Speothos'', and genetic evidence suggests that its closest living relative is the maned wolf of central South America or the African wild dog. The species is listed as Near Threatened by the IUCN. In Brazil it is called ''cachorro-vinagre'' ("vinegar dog") or ''cachorro-do-mato'' ("bush dog"). In Spanish-speaking countries it is called ''perro vinagre'' ("vinegar dog"), ''zorro vinagre'' ("vinegar fox"), ''perro de agua'' ("water dog"), or ''perro de monte'' ("mountain dog"). Description Adult bush dogs have soft long brownish-tan fur, with a lighter reddish tinge on the head, neck and back and a bushy tail, while the underside is d ...

Speothos Pacivorus
The Pleistocene bush dog (''Speothos pacivorus'') is an extinct canid species in the genus ''Speothos'' from the Late Pleistocene. It was a relative of the extant bush dog. When compared to the bush dog, ''S. pacivorus'' had an overall larger body size, a straighter radial shaft The radius or radial bone is one of the two large bones of the forearm, the other being the ulna. It extends from the lateral side of the elbow to the thumb side of the wrist and runs parallel to the ulna. The ulna is usually slightly longer than ... and a double-rooted second lower molar.* References Speothos Prehistoric canines Holocene extinctions Pleistocene carnivorans Pleistocene mammals of South America Lujanian Pleistocene Brazil Holocene Brazil Fossils of Brazil Fossil taxa described in 1839 {{canid-stub ...

Cerdocyonina
Cerdocyonina is an extant subtribe of the canines and is exclusively endemic to the Americas. Often described to be "fox-like" in appearance and behavior, they are more closely related to the wolf-like canids such as ''Canis'' than they are to the fox genus ''Vulpes''. Its members are colloquially known as the South American canids and there are 10 extant species. They are sometimes referred to as South American foxes in the older literature, but the term zorro has been recommended by mammalogists to avoid confusion with the true foxes of the tribe Vulpini, which includes the genus ''Vulpes.'' Taxonomy Cerdocyonina is a natural lineage whose common ancestor was sister to the ''Eucyon–Canis–Lycaon'' lineage. It is represented in the fossil record by ''Cerdocyon'' 6–5 million years ago, and by ''Theriodictis'' and ''Chrysocyon'' 5–4 million years ago. It most likely emerged from Central America. The fossil of a large form of the extinct ''Theriodictis'' that dates 2 millio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maned Wolf
The maned wolf (''Chrysocyon brachyurus'') is a large canine of South America. It is found in Argentina, Brazil, Bolivia, Peru, and Paraguay, and is almost extinct in Uruguay. Its markings resemble those of foxes, but it is neither a fox nor a wolf. It is the only species in the genus ''Chrysocyon'' (meaning "golden dog"). It is the largest canine in South America, weighing and up to at the withers. Its long, thin legs and dense reddish coat give it an unmistakable appearance. The maned wolf is a crepuscular and omnivorous animal adapted to the open environments of the South American savanna, with an important role in the seed dispersal of fruits, especially the wolf apple (''Solanum lycocarpum''). The maned wolf is a solitary animal. It communicates primarily by scent marking, but also gives a loud call known as "roar-barking". This mammal lives in open and semi-open habitats, especially grasslands with scattered bushes and trees, in the Cerrado of south, central-west, and ...

Canid
Canidae (; from Latin, ''canis'', "dog") is a biological family of dog-like carnivorans, colloquially referred to as dogs, and constitutes a clade. A member of this family is also called a canid (). There are three subfamilies found within the canid family, which are the extinct Borophaginae and Hesperocyoninae, and the extant Caninae. The Caninae are known as canines, and include domestic dogs, wolves, coyotes, foxes, jackals and other extant and extinct species. Canids are found on all continents except Antarctica, having arrived independently or accompanied human beings over extended periods of time. Canids vary in size from the gray wolf to the fennec fox. The body forms of canids are similar, typically having long muzzles, upright ears, teeth adapted for cracking bones and slicing flesh, long legs, and bushy tails. They are mostly social animals, living together in family units or small groups and behaving cooperatively. Typically, only the dominant pair in a group breed ...

Dhole
The dhole (''Cuon alpinus''; ) is a canid native to Central, South, East and Southeast Asia. Other English names for the species include Asian wild dog, Asiatic wild dog, Indian wild dog, whistling dog, red dog, red wolf, and mountain wolf. It is genetically close to species within the genus ''Canis'', but distinct in several anatomical aspects: its skull is convex rather than concave in profile, it lacks a third lower molar and the upper molars sport only a single cusp as opposed to between two and four. During the Pleistocene, the dhole ranged throughout Asia, Europe and North America but became restricted to its historical range 12,000–18,000 years ago. The dhole is a highly social animal, living in large clans without rigid dominance hierarchies and containing multiple breeding females. Such clans usually consist of about 12 individuals, but groups of over 40 are known. It is a diurnal pack hunter which preferentially targets large and medium-sized ungulates. I ...

Mammal Genera
There are currently 1,258 genera, 156 families, 27 orders, and around 5,937 recognized living species of mammal. Mammalian taxonomy is in constant flux as many new species are described and recategorized within their respective genera and families. The taxonomy represented here is a compilation of the most logical and up-to-date information on mammalian taxonomy from many sources, the main ones being ''Handbook of the Mammals of the World'' series and ''Mammal Species of the World''.

Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...
