Caninae
Caninae (whose members are known as canines () is the only living subfamily within Canidae, alongside the extinct Borophaginae and Hesperocyoninae. They first appeared in North America, during the Oligocene around 35 million years ago, subsequently spreading to Asia and elsewhere in the Old World at the end of the Miocene, 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 killing bite compared with the ''Leptocyon'' which were designed for snatching small, f ...

Dire Wolf
The dire wolf (''Aenocyon dirus'' ) is an Extinction, extinct species of Caninae, canine which was native to the Americas during the Late Pleistocene and Early Holocene epochs (125,000–10,000 years ago). The species was named in 1858, four years after the first Fossil, specimen had been found. Two subspecies are proposed, ''Aenocyon dirus guildayi'' and ''Aenocyon dirus dirus'', but this assignment has been recently considered questionable. 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 plains, grasslands, and some Montane ecosystem, forested mountain areas of North America and the arid Savanna#Savanna ecoregions, savanna of South America. The sites range in elevation from sea level to . Dire wolf fossils have rarely been found north of 42nd parallel north, 42°N latitude; there have been only five unconfirmed records above this latitude. This ...

Canini (tribe)
Canini is a taxon which represents the dog-like Tribe (biology), 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 (phylogenetics), 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''.

Canis
''Canis'' is a genus of the Caninae which includes multiple extant taxon, extant species, such as Wolf, 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 Phylogenetics, phylogenetically closely related with 78 chromosomes and can potentially hybrid (biology), interbreed. In 1926, the International Commission on Zoological Nomenclature (ICZN) in Opinion 91 included Genus ''Canis'' on its ''Official Lists and Indexes o ...

Vulpini
Vulpini is a Tribe (biology), tribe which represents the fox-like taxon of the subfamily Caninae (the canines), and is sister to the dog-like tribe Canini (tribe), Canini. It comprises the 15 extant and 21 Extinction, extinct species found on all continents. Genera Taxonomy The taxonomy of Carnivora in general and Canidae in particular correlates with various diagnostic features of the dentition and basicranium. Regarding Vulpini, Tedford has remarked: The cladogram below is based on the phylogeny of Lindblad-Toh (2005) modified to incorporate recent findings on ''Vulpes''.

Cerdocyonina
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 ...

Dhole
The dhole ( ; ''Cuon alpinus'') is a canid native to South, East and Southeast Asia. It is anatomically distinguished from members of the genus ''Canis'' in several aspects: its skull is convex rather than concave in profile, it lacks a third lower molar, and the upper molars possess only a single cusp as opposed to between two and four. During the Pleistocene, the dhole ranged throughout Asia, with its range also extending into Europe (with a single putative, controversial record also reported from North America) but became restricted to its historical range 12,000–18,000 years ago. It is now extinct in Central Asia, parts of Southeast Asia, and possibly the Korean peninsula and Russia. Genetic evidence indicates that the dhole was the result of reticulate evolution, emerging from the hybridization between a species closely related to genus ''Canis'' and one from a lineage closely related to the African wild dog (''Lycaon pictus''). The dhole is a highly social ani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xenocyon
''Xenocyon'' ("strange dog") is an extinct group of canids, either considered a distinct genus or a 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'' is thought to be closely related and possibly ancestral to modern dhole and the African wild dog, as well as the insular Sardinian dhole. 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 ...

Black-backed Jackal
The black-backed jackal (''Lupulella mesomelas'') is a medium-sized Caninae, canine native to East Africa, eastern and southern Africa. These regions are separated by roughly . 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 on the IUCN Red List as least concern due to its widespread range and adaptability, although it is still persecuted as a livestock predator and rabies Vector (epidemiology), vector. Compared to members of the genus ''Canis'', the black-backed jackal is a very ancient species, and has changed little since the Pleistocene, being the most Basal (phylogenetics), basal wolf-like canine. It has a reddish brown to tan coat and a black saddle that extends from the shoulders to the base of the tail. It is a Monogamy in animals, monogamous animal, whose young may remain with the family ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 15 kg. It was one of the few North American mammals which invaded Eurasia about 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. Numerous species were previously described as ''Canis'', including '' Eucyon ferox''. ''Eucyon davisi'' The jackal-sized ''Eucyon'' existed in North America from 10 ...

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 epoch (geology), geological epoch of the Neogene Period an ...

Canina (subtribe)
Canina is a taxon which represents the wolf-like Subtribe (biology), subtribe of the Tribe (biology), tribe Canini (tribe), Canini, and is sister to the subtribe Cerdocyonina. Fossil, Fossils of this group date to 5 million years ago; however, they are likely to have been in existence 9 million years ago. Its members as a group are colloquially known as the wolf-like canids. Taxonomy Members of the subtribe Canina are able to produce canid hybrids due to their shared karyotype of 78 chromosomes arranged in 39 pairs. The cladogram below is based on the phylogeny of Lindblad-Toh ''et al''. (2005), modified to incorporate recent findings on ''Canis'' species.

Lupulella
''Lupulella'' is a genus of canine found in Africa. This genus consists of only two extant species, the black-backed jackal (''Lupulella mesomelas'') and the side-striped jackal (''Lupulella adusta''). Taxonomy The two species had previously been considered members of the genus ''Canis''. In 2017, a taxonomic review recommended that these two species be recognised as genus ''Lupulella''. In response to this review, the American Society of Mammalogists recognised the new genus. In 2019, a workshop hosted by the IUCN The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status .../SSC Canid Specialist Group recommends that because DNA evidence shows the side-striped jackal (''Canis adustus'') and black-backed jackal (''Canis mesomelas'') to form a monophyletic lineage that sits outside of the ...
