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 ...

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] |
Coyote
The coyote (''Canis latrans'') is a species of canis, 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, 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 sub ...

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] |
Canid
Canidae (; from Latin, ''canis'', "dog") is a biological family of dog-like carnivorans, colloquially referred to as dogs, and constitutes a clade. A member of this family is also called a canid (). There are three subfamilies found within the canid family, which are the extinct Borophaginae and Hesperocyoninae, and the extant Caninae. The Caninae are known as canines, and include domestic dogs, wolves, coyotes, foxes, jackals and other extant and extinct species. Canids are found on all continents except Antarctica, having arrived independently or accompanied human beings over extended periods of time. Canids vary in size from the gray wolf to the fennec fox. The body forms of canids are similar, typically having long muzzles, upright ears, teeth adapted for cracking bones and slicing flesh, long legs, and bushy tails. They are mostly social animals, living together in family units or small groups and behaving cooperatively. Typically, only the dominant pair in a group breed ...

Canina (subtribe)
Canina is a taxonomic rank which represents the wolf-like sub-tribe of the tribe Canini, and is sister to the sub-tribe Cerdocyonina. 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 ''Canis'' is a genus of the Caninae which includes multiple extant species, such as wolves, dogs, coyotes, and golden jackals.

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 life The gibbons (family Hylobatidae) and orangutans (genus ''Pongo'') are 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 to 8 million years ago, that is, during the Late Miocene.

Ringold Formation
The Ringold Formation is a geologic formation in Eastern Washington, United States. The formation consists of sediment laid down by the Columbia River following the flood basalt eruptions of the Columbia River Basalt Group, and reaches up to thick in places. It preserves fossils dating back to the Neogene period. Exposures of the Ringold Formation can be found from Hanford Reach National Monument north to the Moses Lake area. Large portions of the formation are buried by other sediment deposits, extending as far as Wallula Gap southeast of Kennewick. In recent years, irrigation water entering the groundwater system has destabilized some Ringold Formation slopes and cliffs, causing landslides. The formation was named in 1917 for a school of the same name that existed at the time. Ringold School was located on the Franklin County side of the Columbia River to the south of Savage Island. Geology During the flood basalt eruptions before the sediments were laid down, the Columbia R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nebraska
Nebraska () is a state in the Midwestern region of the United States.

The state is crossed by many historic trails, including that of the Lewis and Clark Expedition. Nebraska's area is just over with a population of over 1.9 million. Its capital is Lincoln, and its largest city is Omaha, which is on the Missouri River. Nebraska was admitted into the United States in 1867, two years after the end of the American Civil War.

Mongolia
Mongolia; Mongolian script: , , ; lit. "Mongol Nation" or "State of Mongolia" () is a landlocked country in East Asia, bordered by Russia to the north and China to the south. It covers an area of , with a population of just 3.3 million, making it the world's most sparsely populated sovereign nation.
