Canis Major Constellation Map
''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 ...

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.

Canis Simensis
The Ethiopian wolf (''Canis simensis''), also called the red jackal, the Simien jackal or Simien fox, is a canine native to the Ethiopian Highlands. In southeastern Ethiopia, it is also known as the horse jackal. It is similar to the coyote in size and build, and is distinguished by its long and narrow skull, and its red and white fur. Unlike most large canids, which are widespread, generalist feeders, the Ethiopian wolf is a highly specialised feeder of Afroalpine rodents with very specific habitat requirements. It is one of the world's rarest canids, and Africa's most endangered carnivore. The species's current range is limited to seven isolated mountain ranges at altitudes of 3,000–4,500 m, with the overall adult population estimated at 360–440 individuals in 2011, more than half of them in the Bale Mountains. The Ethiopian wolf is listed as endangered by the IUCN, on account of its small numbers and fragmented range. Threats include increasing pressure from expanding h ...

Canis Falconeri
''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 ''Cani ...

Canis Antonii
It is widely agreed that the evolutionary lineage of the grey wolf can be traced back 2 million years to the Early Pleistocene species ''Canis etruscus,'' and its successor the Middle Pleistocene ''Canis mosbachensis''. The grey wolf ''Canis lupus'' is a highly adaptable species that is able to exist in a range of environments and which possesses a wide distribution across the Holarctic. Studies of modern grey wolves have identified distinct sub-populations that live in close proximity to each other. This variation in sub-populations is closely linked to differences in habitat – precipitation, temperature, vegetation, and prey specialization – which affect cranio-dental plasticity. The earliest specimens of the modern grey wolf date to around 400,000 years ago, or possibly earlier to 1 million years ago. Most modern wolves share most of their common ancestry within the last 25-23,000 years from earlier Siberian wolf populations. While some sources have suggested that this is t ...

Canis Variabilis
''Canis mosbachensis'' is an extinct wolf that inhabited Europe from the late Early Pleistocene to the Middle Pleistocene, around 1.4 million to 400,000 years ago. ''Canis mosbachensis'' is widely considered to have descended from the earlier '' Canis etruscus'', and to be the ancestor of the living grey wolf (''Canis lupus'') with some considering it as a subspecies of the wolf as ''Canis lupus mosbachensis''. The morphological distinction between ''C. mosbachensis'' and ''C. lupus'' has historically been vague, and attribution of fossils to ''C. mosbachensis'' or to ''C. lupus'' around the transition time between the two species is ambiguous. Taxonomy ''Canis mosbachensis'' was named by Soergel in 1925 based on a collection of remains found at Mosbach, Germany. It was later demonstrated that another canine, '' Xenocyon lycaonoides'' was also present at the site, meaning that remains at the site can't be attributed to ''C. mosbachensis'' purely based on their canine nature.

Canis Lepophagus
''Canis lepophagus'' (Latin: : 'dog'; : 'hare' or 'rabbit'; suffix : '-eating'; hence hare-eating dog) is an extinct species of canid which was endemic to much of North America during the Early Pliocene. It is notable because its lineage is proposed to have led to both wolves and coyotes. Evolution Kurten proposed that the Blancan ''C. lepophagus'' derived from smaller Miocene ''Canis'' species in North America. It then became widespread across Eurasia where it was either identical to, or closely related with, '' C. arnensis'' of Europe. Wang proposed a linear progression from ''Eucyon davisi'' to ''C. lepophagus'' to the coyote. Johnston describes ''C. lepophagus'' as having a more slender skull and skeleton than in the modern coyote. Nowak found that the early populations had small, delicate and narrowly proportioned skulls that resemble small coyotes and appear to be ancestral to ''C. latrans''. Johnson noted that some specimens found in Cita Canyon, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canis Etruscus
''Canis etruscus'' (the Etruscan wolf), is an extinct species of canine that was endemic to Mediterranean Europe and Crimean peninsula during the Early Pleistocene. The Etruscan wolf is described as a small wolf-like dog. It is widely agreed to be the ancestor of '' Canis mosbachensis'', and thus ultimately the modern grey wolf (''Canis lupus''). Taxonomy The fossil record for ancient vertebrates is composed of rarely occurring fragments, from which it is often impossible to obtain genetic material. Researchers are limited to morphologic analysis but it is difficult to estimate the intra-species and inter-species variations and relationships that existed between specimens across time and place. Some observations are debated by researchers who do not always agree, and hypotheses that are supported by some authors are challenged by others. Several species of Caninae from the Pleistocene of Europe have been described. Most of their systematic and phylogenetic relationships have n ...

Canis Edwardii
''Canis edwardii'', also known as Edward's wolf, is an extinct species of wolf in the genus ''Canis'' which was endemic to North America three million years ago from the Late Blancan stage of the Pliocene epoch and was extinct by the end of the Irvingtonian stage of the Pleistocene epoch. Taxonomy ''Canis edwardii'' was named by Gazin in 1942. Xiaoming Wang (paleontologist), Xiaoming Wang and Richard H. Tedford proposed that the genus ''Canis'' was the descendant of the coyote-like ''Eucyon davisi'' and its remains first appeared in the Miocene (6 Mya) in the Southwestern USA and Mexico. By the Pliocene (5 Mya), the larger ''Canis lepophagus'' appeared in the same region, and by the Early Pleistocene (1 Mya) ''Canis latrans'' (the coyote) was in existence. They proposed that the progression from ''Eucyon davisi'' to ''C. lepophagus'' to the coyote was linear evolution. Additionally, ''C. edwardii'', ''C. latrans'', and ''C. aureus'' thought to have formed a small clade togethe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
