Vulpini
Vulpini is a taxonomic rank which represents the fox-like tribe of the subfamily Caninae (the canines), and is sister to the dog-like tribe Canini. Genera Taxonomy The taxonomy of Carnivora in general and Canidae in particular correlates with various diagnostic features of the dentition Dentition pertains to the development of teeth and their arrangement in the mouth. In particular, it is the characteristic arrangement, kind, and number of teeth in a given species at a given age. That is, the number, type, and morpho-physiolo ... and basicranium. Rergarding Vulpini, Tedford has remarked: The cladogram below is based on the phylogeny of Lindblad-Toh (2005) modified to incorporate recent findings on ''Vulpes''.

Caninae
The Caninae, known as canines, are one of three subfamily, subfamilies found within the Canidae, canid family. The other two canid subfamilies are the extinct Borophaginae and Hesperocyoninae. The Caninae includes all living canids and their most recent fossil relatives. Their fossils were first found in North America and dated to the Oligocene era, then spreading to Asia at the end of the Miocene era, some 7 million to 8 million years ago. Taxonomy and lineage The genus ''Leptocyon'' (Greek: ''leptos'' slender + ''cyon'' dog) includes 11 species and was the first primitive canine. They were small and weighed around 2 kg. They first appeared in Sioux County, Nebraska in the Orellan era 34-32 million years ago, which was the beginning of the Oligocene. This was the same time as the appearance of the Borophaginae with whom they share features, indicating that these were two sister groups. Borophaginae skull and dentition were designed for a powerful killi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferrucyon
''Ferrucyon'' is an extinct genus of omnivorous mammal of the family Canidae, which inhabited North America during the Pliocene, Blancan in the NALMA classification, from about 4.9 to approximately 2.6 Ma. The type species, ''F. avius'', was originally interpreted as a relative of the modern crab-eating fox, and described as a species belonging to the genus ''Cerdocyon''. Ruiz-Ramoni ''et al.'' (2020) reinterpreted it as a vulpine canid related to North American species '' Metalopex macconnelli'', and to the Eurasian genus ''Nyctereutes''. This reinterpretation necessitated removal of ''"Cerdocyon" avius'' from the genus ''Cerdocyon'', and Ruiz-Ramoni ''et al.'' (2020) transferred it to the separate genus ''Ferrucyon''. Taxonomy ''Cerdocyon'' was named by Hamilton-Smith (1839). It was assigned to Canidae by Hamilton-Smith (1839) and Carroll (1988).R. L. Carroll. 1988. Vertebrate Paleontology and Evolution. W.H.

Canini (tribe)
Canini is a taxonomic rank which represents the dog-like tribe of the subfamily Caninae (the canines), and is sister to the fox-like tribe Vulpini. The Canini came into existence 9 million years ago. This group was first represented by ''Eucyon'', mostly by ''Eucyon davisi'' that was spread widely across North America and is basal to the other members of the tribe. Its members are informally known as true dogs. Taxonomy Members of this tribe include: Common names of most of the South American canines include "fox", based on resemblance, but they are more closely related to wolves than to ''vulpini'', the Eurasian and North American foxes. The cladogram below is based on the phylogeny of Lindblad-Toh ''et al''. (2005), modified to incorporate recent findings on ''Canis'' species, ''Lycalopex'' species, and ''Dusicyon ''Dusicyon'' is an extinct genus of South American canids.

Vulpes Lagopus
The Arctic fox (''Vulpes lagopus''), also known as the white fox, polar fox, or snow fox, is a small fox native to the Arctic regions of the Northern Hemisphere and common throughout the Arctic tundra biome. It is well adapted to living in cold environments, and is best known for its thick, warm fur that is also used as camouflage. It has a large and very fluffy tail. In the wild, most individuals do not live past their first year but some exceptional ones survive up to 11 years. Its body length ranges from , with a generally rounded body shape to minimize the escape of body heat. The Arctic fox preys on many small creatures such as lemmings, voles, ringed seal pups, fish, waterfowl, and seabirds. It also eats carrion, berries, seaweed, and insects and other small invertebrates. Arctic foxes form monogamous pairs during the breeding season and they stay together to raise their young in complex underground dens. Occasionally, other family members may assist in raising their you ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metalopex
''Metalopex'' is an extinct hypocarnivorous canid mammal similar to ''Vulpes'' endemic to Late Miocene North America. Its sister taxon is the extant ''Urocyon''; together, the two genera form a clade based on dentition. These same dental characteristics are shared by ''Otocyon'' and ''Protocyon ''Protocyon'' is an extinct genus of large canid endemic to South and North America during the Late Pleistocene living from 781 to 12thousand years ago.

Nyctereutes
''Nyctereutes'' (Greek: ''nyx, nykt-'' "night" + ''ereutēs'' "wanderer") is a genus of canid which includes only two extant species both known as raccoon dogs; the common raccoon dog (''Nyctereutes procyonoides'') and the Japanese raccoon dog (''Nyctereutes viverrinus''). ''Nyctereutes'' first entered the fossil record 5.5 million years ago ( Mya) in northern China. It was one of the earliest canines to arrive in the Old World. All but two species became extinct before the 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.

Prototocyon
''Prototocyon'' or ''Sivacyon'' is an extinct genus of small omnivorous canid living during the Late Pliocene and Early Pleistocene. Taxonomy ''Prototocyon'' was named by Pohle (1928) and was assigned to Canidae by Carroll (1988). Old literature relates it to ''Vulpes bengalensis'', but not more modern literature (e.g. McKenna and Bell. Published 9 August 2006 by the American Society of Mammalogists) Tedford et al. 2009 suggest that ''Prototocyon'' and '''' form a clade. Descript ...

Fox - British Wildlife Centre (17429406401)
Foxes are small to medium-sized, omnivorous mammals belonging to several genera of the family Canidae. They have a flattened skull, upright, triangular ears, a pointed, slightly upturned snout, and a long bushy tail (or ''brush''). Twelve species belong to the monophyletic "true foxes" group of genus ''Vulpes''. Approximately another 25 current or extinct species are always or sometimes called foxes; these foxes are either part of the paraphyletic group of the South American foxes, or of the outlying group, which consists of the bat-eared fox, gray fox, and island fox. Foxes live on every continent except Antarctica. The most common and widespread species of fox is the red fox (''Vulpes vulpes'') with about 47 recognized subspecies. The global distribution of foxes, together with their widespread reputation for cunning, has contributed to their prominence in popular culture and folklore in many societies around the world. The hunting of foxes with packs of hounds, long an es ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vulpes Corsac
The corsac fox (''Vulpes corsac''), also known simply as a corsac, is a medium-sized fox found in steppes, semi-deserts and deserts in Central Asia, ranging into Mongolia and northern China. Since 2004, it has been classified as ''least concern'' by IUCN, but populations fluctuate significantly, and numbers can drop tenfold within a single year. It is also known as the steppe fox. The word "corsac" is derived from the Russian name for the animal, ''"korsák"'' (корса́к), derived ultimately from Turkic "karsak". Description The Corsac fox is a medium-sized fox, with a head and body length of , and a tail long. Adults weigh from . It has grey to yellowish fur over much of the body, with paler underparts and pale markings on the mouth, chin, and throat. During the winter, the coat becomes much thicker and silkier in texture, and is straw-grey in colour, with a darker line running down the back. For a fox, it has small teeth and a wide skull.

Vulpes Chama
The Cape fox (''Vulpes chama''), also called the asse, cama fox or the silver-backed fox, is a small species of fox, native to southern Africa. It is also called a South African version of a fennec fox due to its similarly big ears. It is the only "true fox" occurring in sub-Saharan Africa, and it retains primitive characteristics of ''Vulpes'' because it diverged early in the evolutionary history of the group. Description ''Vulpes chama'' is a small-built canid, usually measuring long, not including its tail, which is typically . It is tall at the shoulder, and usually weighs from . The skull is very similar to that of '' V. bengalensis'', although the cranium of ''V. chama'' is slightly wider and the maxillary region is slightly shorter. The ears are relatively large and sharp, the muzzle is small and pointed. Pelage colour is silvery-gray, tawny at the back of the ears, with white hairs appearing around the side of the pinna in the center. The colour of the neck and si ...
