''Hesperocyon'' is an extinct genus of Canidae, canids (subfamily Hesperocyoninae, family Canidae) that was endemic to North America, ranging from southern Canada to Colorado. It appeared during the Uintan age, –Bridgerian North American Stage, Bridgerian age (NALMA) of the Mid-Eocene– 42.5 Ma to 31.0 Ma. (Appearance event ordination, AEO). ''Hesperocyon'' existed for approximately . Taxonomy ''Hesperocyon'' was assigned to Borophagini by Wang et al. in 1999 and was the earliest of the canids to evolve after the Caniformia-Feliformia split some 42 million years ago. Fossil evidence dates ''Hesperocyon gregarius'' to at least 37 mya, but the oldest ''Hesperocyon'' has been dated at 39.74 mya from the Duchesnean North American land mammal age. The Canidae subfamily Hesperocyoninae probably arose out of ''Hesperocyon'' to become the first of the three great dogs groups: Hesperocyoninae (~40–30 Ma), Borophaginae (~36–2 Ma), and the Caninae lineage that led to the present-day ...

Civet
A civet () is a small, lean, mostly nocturnal mammal native to tropical Asia and Africa, especially the tropical forests. The term civet applies to over a dozen different species, mostly from the family Viverridae. Most of the species diversity is found in southeast Asia. The best-known species is the African civet, ''Civettictis civetta'', which historically has been the main species from which a musky scent used in perfumery, also referred to as " civet", was obtained. Naming The common name is used for a variety of carnivoran mammal species, mostly of the family Viverridae. The African palm civet (''Nandinia binotata'') is genetically distinct and belongs in its own monotypic family, Nandiniidae. Civets are also called "toddycats" in English, "Mara Patti" in Malayalam, "musang" in Malay and Indonesian, and ''urulǣvā'' () in Sinhalese. There can be confusion among speakers of Malay because the indigenous word "musang" has been mistakenly applied to foxes by printed m ...

''Ectopocynus'' ("strange dog") is an extinct genus of bone crushing canid which inhabited North America from the Oligocene to the Early Miocene. It lived from 33.3 to 16.0 Ma and existed for approximately . Remains of ''Ectopocynus'' are limited to mandibles and teeth only.

Jackal
Jackals are medium-sized canids native to Africa and Eurasia. While the word "jackal" has historically been used for many canines of the subtribe canina, in modern use it most commonly refers to three species: the closely related black-backed jackal (''Lupulella mesomelas'') and side-striped jackal (''Lupulella adusta'') of sub-Saharan-Africa, and the golden jackal (''Canis aureus'') of south-central Europe and Asia. The African golden wolf (''Canis lupaster'') was also formerly considered as a jackal. While they do not form a monophyletic clade, all jackals are opportunistic omnivores, predators of small to medium-sized animals and proficient scavengers. Their long legs and curved canine teeth are adapted for hunting small mammals, birds, and reptiles, and their large feet and fused leg bones give them a physique well-suited for long-distance running, capable of maintaining speeds of for extended periods of time. Jackals are crepuscular, most active at dawn and dusk. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coyote
The coyote (''Canis latrans'') is a species of canine native to North America. It is smaller than its close relative, the wolf, and slightly smaller than the closely related eastern wolf and red wolf. It fills much of the same ecological niche as the golden jackal does in Eurasia. The coyote is larger and more predatory and was once referred to as the American jackal by a behavioral ecologist. Other historical names for the species include the prairie wolf and the brush wolf. The coyote is listed as least concern by the International Union for Conservation of Nature, due to its wide distribution and abundance throughout North America. The species is versatile, able to adapt to and expand into environments modified by humans. It is enlarging its range by moving into urban areas in the eastern U.S. and Canada. The coyote was sighted in eastern Panama (across the Panama Canal from their home range) for the first time in 2013. The coyote has 19 recognized subspecies. The avera ...

Vulpes
'' Vulpes '' is a genus of the sub-family Caninae. The members of this genus are colloquially referred to as true foxes, meaning they form a proper clade. The word "fox" occurs in the common names of all species of the genus, but also appears in the common names of other canid species. True foxes are distinguished from members of the genus '' Canis'', such as domesticated dogs, wolves, jackals and coyotes, by their smaller size (5–11 kg), longer, bushier tail, and flatter skull. They have black, triangular markings between their eyes and nose, and the tip of their tail is often a different color from the rest of their pelt. The typical lifespan for this genus is between two and four years, but can reach up to a decade. Extant species Within ''Vulpes'', 12 separate extant species and four fossil species are described: Early history The oldest known fossil species within ''Vulpes'' is ''V. riffautae'', dating back to the late Miocene of Chad, which is within the ...
