Cerdocyonina (subtribe)
Cerdocyonina is an extant subtribe of the canini and is endemic to the Americas. It is a sister lineage to the subtribe Canina. There are 10 extant species. Its members are colloquially known as the South American canids. Taxonomy Cerdocyonina is a natural lineage whose common ancestor was sister to the ''Eucyon–Canis–Lycaon'' lineage. It is represented in the fossil record of North America by ''Cerdocyon'' 6-5 million years ago, and by '' Theriodictis'' and ''Chrysocyon'' 5–4 million years ago. The fossil of a large form of the extinct ''Theriodictis'' that dates 2 million years ago was found in Florida. The maned wolf and an extinct species of the crab-eating zorro were in North America around this time, which was before the Isthmus of Panama came into being, indicating the origin of the Cerdocyonina in North America. Prior to the 1990s there have been different systematic hypotheses pertaining to the relationships among South American canids, most frequent was the not ...

Late Miocene
The Late Miocene (also known as Upper Miocene) is a sub-epoch of the Miocene epoch (geology), Epoch made up of two faunal stage, stages. The Tortonian and Messinian stages comprise the Late Miocene sub-epoch, which lasted from 11.63 Ma (million years ago) to 5.333 Ma. The evolution of ''Homo'' The gibbons (family Hylobatidae) and orangutans (genus ''Pongo'') were the first groups to split from the line leading to the hominins, including humans, then gorillas (genus ''Gorilla''), and finally chimpanzees and bonobos (genus ''Pan (genus), Pan''). The splitting date between hominin and chimpanzee lineages is placed by some between 4 and 8 million years ago, that is, during the Late Miocene.

Americas
The Americas, sometimes collectively called America, are a landmass comprising the totality of North America and South America.''Webster's New World College Dictionary'', 2010 by Wiley Publishing, Inc., Cleveland, Ohio. When viewed as a single continent, the Americas or America is the 2nd largest continent by area after Asia, and is the 3rd largest continent by population. The Americas make up most of the land in Earth's Western Hemisphere and comprise the New World. Along with their Lists of islands of the Americas, associated islands, the Americas cover 8% of Earth's total surface area and 28.4% of its land area. The topography is dominated by the American Cordillera, a long chain of mountains that runs the length of the west coast. The flatter eastern side of the Americas is dominated by large river basins, such as the Amazon basin, Amazon, St. Lawrence River–Great Lakes, Mississippi River System, Mississippi, and Río de la Plata Basin, La Plata basins.

Falkland Islands Wolf
The Falkland Islands wolf (''Dusicyon australis'') was the only native land mammal of the Falkland Islands. This endemic canid became extinct in 1876, the first known canid to have become extinct in historical times. Traditionally, it had been supposed that the most closely related genus was '' Lycalopex'', including the culpeo, which has been introduced to the Falkland Islands in modern times. A 2009 cladistic analysis of DNA identified the Falkland Islands wolf's closest living relative as the maned wolf (''Chrysocyon brachyurus''), an unusually long-legged, fox-like South American canid, from which it separated about 6.7 million years ago. However, the Falkland Islands wolf diverged from its mainland ancestor ''Dusicyon avus'' very recently, around 16,000 years ago. ''Dusicyon avus'' persisted on the South American mainland until around 400 years ago. The Falkland Islands wolf existed on both West and East Falkland, but Charles Darwin was uncertain if they were differentiate ...

Chrysocyon Brachyurus
The maned wolf (''Chrysocyon brachyurus'') is a large caninae, 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 a red fox, but it is neither a fox nor a wolf. It is the only species in the genus ''Chrysocyon'' (meaning "golden dog" in : chryso-kyōn). 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 a distinct 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 sou ...

Speothos Venaticus
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 described by Peter Wilhelm Lund from fossils in Brazilian caves and was believed to be extinct. The bush dog is the only extant 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 ('vinegar dog') and ('bush dog'). In Spanish-speaking countries, it is called ('vinegar dog'), ('vinegar fox'), ('water dog'), and ('shrub or woodland 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 dark, sometimes with a lighter throat patch. Younger individuals, however, have black fur over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canis Nehringi
''Canis nehringi'' is an extinct species of canid. ''Canis gezi'', a poorly known small wolf from the Ensenadan age of South America, appears to have given rise to ''Canis nehringi'', a Lujanian age species from Argentina. The species was first described by Florentino Ameghino in 1902.Prevosti et al., 2004, p.32 ''Canis gezi'' ''Canis dirus'' made its appearance in South America in the late Pleistocene, and seems to have been restricted to the north and west coasts. Its remains have not been found in the area of Argentina that produced ''Canis gezi'' and ''Canis nehringi'', and their remains have not been found elsewhere in South America. Some researchers have proposed that ''Canis dirus'' may have originated in South America. In 1988, a study of these two large South American wolves described them with ''Canis gezi'' found in South American Ensenadan deposits that relate to the North American late Blancan and Irvingtonian, and ''Canis nehringi'' found in South American Luja ...

Richard H
Richard is a male given name. It originates, via Old French, from Old Frankish and is a compound of the words descending from Proto-Germanic language">Proto-Germanic ''*rīk-'' 'ruler, leader, king' and ''*hardu-'' 'strong, brave, hardy', and it therefore means 'strong in rule'. Nicknames include " Richie", " Dick", " Dickon", " Dickie", " Rich", " Rick", "Rico (name), Rico", " Ricky", and more. Richard is a common English (the name was introduced into England by the Normans), German and French male name. It's also used in many more languages, particularly Germanic, such as Norwegian, Danish, Swedish, Icelandic, and Dutch, as well as other languages including Irish, Scottish, Welsh and Finnish. Richard is cognate with variants of the name in other European languages, such as the Swedish "Rickard", the Portuguese and Spanish "Ricardo" and the Italian "Riccardo" (see comprehensive variant list below).

Atelocynus
The short-eared dog (''Atelocynus microtis''), also known as the small-eared dog, is a unique and elusive canid species endemic to the Amazonian basin. This is the only species assigned to the genus ''Atelocynus''. Other names The short-eared dog has many names in the local languages where it is endemic, including ' in Portuguese, ' ("short-ear fox") in Spanish, ' in Chiquitano, ' in Yucuna, ' in Guarayu, ' in Mooré, and ''achuj'' in Ninam and Mosetén. Other common names in Spanish include ' ("blue-eyed fox"), ' ("savannah fox"), and ' ("black fox"). Evolution and systematics In 2022, a study sequenced the genomes of the living members of the subtribe Cerdocyonina, which indicates that they commenced diversifying from a common ancestor between 3.9—3.5 million years ago. This finding is consistent with the ancestor arriving in South America from Central America through the Isthmus of Panama and then entering into eastern South America. The subtribe then expanded to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
