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] |
Dire Wolf
The dire wolf (''Aenocyon dirus'' ) is an extinct canine. It is one of the most famous prehistoric carnivores in North America, along with its extinct competitor ''Smilodon''. The dire wolf lived in the Americas and eastern Asia during the Late Pleistocene and Early Holocene epochs (125,000–9,500 years ago). The species was named in 1858, four years after the first specimen had been found. Two subspecies are recognized: ''Aenocyon dirus guildayi'' and ''Aenocyon dirus dirus''. The largest collection of its fossils has been obtained from the Rancho La Brea Tar Pits in Los Angeles. Dire wolf remains have been found across a broad range of habitats including the plains, grasslands, and some forested mountain areas of North America, the arid savanna of South America, and the steppes of eastern Asia. The sites range in elevation from sea level to . Dire wolf fossils have rarely been found north of 42°N latitude; there have been only five unconfirmed reports above this latitude. ...

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. The type species is ''Dusicyon australis'', the Falkland Islands wolf. In 1914, Oldfield Thom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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''.

Canis
''Canis'' is a genus of the Caninae which includes multiple extant species, such as wolves, dogs, coyotes, and golden jackals. Species of this genus are distinguished by their moderate to large size, their massive, well-developed skulls and dentition, long legs, and comparatively short ears and tails.Heptner, V. G.; Naumov, N. P. (1998). ''Mammals of the Soviet Union'' Vol.II Part 1a, SIRENIA AND CARNIVORA (Sea Cows, Wolves and Bears). Science Publishers, Inc. USA. pp. 124–129. . Taxonomy The genus ''Canis'' (Carl Linnaeus, 1758) was published in the 10th edition of Systema Naturae and included the dog-like carnivores: the domestic dog, wolves, coyotes and jackals. All species within ''Canis'' are phylogenetically closely related with 78 chromosomes and can potentially interbreed. In 1926, the International Commission on Zoological Nomenclature (ICZN) in Opinion 91 included Genus ''Canis'' on its ''Official Lists and Indexes of Names in Zoology''. In 1955, the ICZN's Directi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cerdocyonina (subtribe)
Cerdocyonina is an extant subtribe of the Canini (tribe), 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'' tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xenocyon
''Xenocyon'' ("strange dog") is an extinct subgenus of ''Canis''. The group includes ''Canis'' (''Xenocyon'') ''africanus'', ''Canis'' (''Xenocyon'') ''antonii'' and ''Canis'' (''Xenocyon'') ''falconeri'' that gave rise to ''Canis'' (''Xenocyon'') ''lycanoides''. The hypercarnivorous ''Xenocyon'' gave rise to the modern dhole and the African wild dog. Taxonomy ''Xenocyon'' is proposed as a subgenus of ''Canis'' named ''Canis'' (''Xenocyon''). One taxonomic authority proposes that as part of this subgenus, the group named ''Canis'' (''Xenocyon'') ex gr. ''falconeri'' (ex gr. meaning "of the group including") would include all of the large hypercarnivorous canids that inhabited the Old World during the Late Pliocene–Early Pleistocene: ''Canis'' (''Xenocyon'') ''africanus'' in Africa, ''Canis'' (''Xenocyon'') ''antonii'' in Asia and ''Canis'' (''Xenocyon'') ''falconeri'' in Europe. Further, these three could be regarded as extreme geographical variations within the one taxon. Thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black-backed Jackal
The black-backed jackal (''Lupulella mesomelas),'' also called the silver-backed jackal, is a medium-sized canine native to eastern and southern Africa. These regions are separated by roughly 900 kilometers. One region includes the southernmost tip of the continent, including South Africa, Namibia, Botswana, and Zimbabwe. The other area is along the eastern coastline, including Kenya, Somalia, Djibouti, Eritrea, and Ethiopia. It is listed by the IUCN as least concern, due to its widespread range and adaptability, although it is still persecuted as a livestock predator and rabies vector. Compared to members of the genus ''Canis'', the black-backed jackal is a very ancient species, and has changed little since the Pleistocene,Kingdon, J. (1977), ''East African Mammals: An Atlas of Evolution in Africa'', Volume 3, Part A: Carnivores, University of Chicago Press, p. 31 being the most basal wolf-like canine, alongside the closely related side-striped jackal.

Urocyon
''Urocyon'' (Greek: "tailed dog") is a genus of Canidae which includes the gray fox (''Urocyon cinereoargenteus'') and the island fox (''Urocyon littoralis''). These two fox species are found in the Western Hemisphere. Whole genome sequencing indicates that ''Urocyon'' is the most basal genus of the living canids. Fossils of what is believed to be the ancestor of the gray fox, ''Urocyon progressus'', have been found in Kansas and date to the Upper Pliocene, with some undescribed specimens dating even older. Extant species Cozumel fox The Cozumel fox is a critically endangered or extinct small gray fox found on the island of Cozumel, Mexico. The last reported sighting was in 2001, but surveys focusing on this species have not yet been carried out. The Cozumel fox has not been scientifically described, but is a dwarf Dwarf or dwarves may refer to: Common uses *Dwarf (folklore), a being from Germanic mythology and folklore * Dwarf, a person or animal with dwarfism Arts, ...

Leptocyon
The genus ''Leptocyon'' (Greek: ''leptos'' slender + ''cyon'' dog) includes 11 species and was the first canine. They were small and weighed around . They first appeared in North America around 34 million years ago in the Oligocene at the same time as the Borophaginae with whom they share features, indicating that these were two sister groups. Borophaginae skull and dentition were designed for a powerful killing bite compared with the Leptocyon which were designed for snatching small, fast-moving prey. The species ''L. delicatus'' is the smallest canid to have existed. At the close of their genus 9 million years ago one ''Leptocyon'' lineage resembled the modern fox. ''Leptocyon'' were small-bodied, fox-like animals with a long, narrow jaw and delicate teeth. They were probably omnivorous, feeding on small animals and fruit in a diet that remained relatively unchanged during the Miocene The Miocene ( ) is the first geological epoch of the Neogene Period and extends from abo ...

Eucyon
''Eucyon'' (Greek: : good, true; : dog) is an extinct genus of medium omnivorous coyote-like canid that first appeared in the Western United States during the late Middle Miocene 10 million years ago. It was the size of a jackal and weighed around 15kg. Its species ''E. zhoui'' was one of a number of North American mammals which invaded East Asia around 5–6 million years ago, followed by the genus going extinct 3 million years ago. This genus is proposed to have given rise to genus ''Canis'' 6 million years ago. Taxonomy ''Eucyon'' was named by Tedford and Qiu in 1996. Phyletically it stood between ''Canis'' and the South American canines that would follow it. In 2009, Tedford revised its diagnosis and described two of its species, ''E. skinneri'' and ''E. davisi'', which was originally named ''Canis davisi'' by Merriam in 1911. ''Eucyon davisi'' The jackal-sized ''Eucyon'' existed in North America from 10 million YBP until the Early Pliocene. Wang and Tedford pr ...

Lycalopex
The South American foxes (''Lycalopex''), commonly called ''raposa'' in Portuguese, or ''zorro'' in Spanish, are a genus from South America of the subfamily Caninae. Despite their name, they are not true foxes, but are a unique canid genus more closely related to wolves and jackals than to true foxes; some of them resemble foxes due to convergent evolution. The South American gray fox, ''Lycalopex griseus'', is the most common species, and is known for its large ears and a highly marketable, russet-fringed pelt. The second-oldest known fossils belonging to the genus were discovered in Chile, and date from 2.0 to 2.5 million years ago, in the mid- to late Pliocene. The Vorohué Formation of Argentina has provided older fossils, dating to the Uquian to Ensenadan (Late Pliocene).Vorohuen ...

Crab-eating Fox
The crab-eating fox (''Cerdocyon thous''), also known as the forest fox, wood fox, bushdog (not to be confused with the bush dog) or maikong, is an extant species of medium-sized canid endemic to the central part of South America since at least the Pleistocene epoch. Like South American foxes, which are in the genus ''Lycalopex'', it is not closely related to true foxes. ''Cerdocyon'' comes from the Greek words ''kerdo'' (meaning fox) and ''kyon'' (dog) referring to the dog- and fox-like characteristics of this animal. Taxonomy and evolution The crab-eating fox was originally described as ''Canis thous'' by Linnaeus (1766), and first placed in its current genus ''Cerdocyon'' by Hamilton-Smith in 1839. Cerdocyonina is a tribe which appeared around 6.0 million years ago (Mya) in North America as ''Ferrucyon avius'' becoming extinct by around 1.4–1.3 Mya. living about . This genus has persisted in South America from an undetermined time, possibly around 3.1 Mya, and continues ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
