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 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 together and because ''C. edwardii'' a ...

Charles Lewis Gazin
Charles Lewis Gazin (1904—1995) was an American vertebrate paleontologist and paleobiologist. Biography Gazin was born in Colorado in 1904. He got an education at California Institute of Technology and earned bachelor's degree there in 1927. He got his master's degree in 1928 and a PhD in 1930, and during the same year he began working for the United States Geological Survey. He was named Assistant Curator in the Division of Vertebrate Paleontology at the Smithsonian Institution in 1932. Ten years later, in 1942 he became Associate Curator and in 1946, a Curator of the Division. He was named Senior Paleobiologist in 1967, and when his retirement came in 1970, he got a Paleobiologist Emeritus position. Twelve years later in 1982 he became a Curator Emeritus. He wrote ninety-nine works on vertebrate paleontology, most of which were focused on mammalian paleontology. Gazin served as President of the Society of Vertebrate Paleontology and was a Director of the American Geologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Pleistocene Species Extinctions
The Pleistocene ( , often referred to as the ''Ice age'') is the geological epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchange, a faunal inter ...

Prehistoric Canines
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wolves
The wolf (''Canis lupus''; plural, : wolves), also known as the gray wolf or grey wolf, is a large Canis, canine native to Eurasia and North America. More than thirty subspecies of Canis lupus, subspecies of ''Canis lupus'' have been recognized, and gray wolves, as popularly understood, comprise wild subspecies. The wolf is the largest Neontology, extant member of the family Canidae. It is also distinguished from other ''Canis'' species by its less pointed ears and muzzle, as well as a shorter torso and a longer tail. The wolf is nonetheless related closely enough to smaller ''Canis'' species, such as the coyote and the golden jackal, to produce fertile Canid hybrid, hybrids with them. The Agouti (coloration), banded fur of a wolf is usually mottled white, brown, gray, and black, although subspecies in the arctic region may be nearly all white. Of all members of the genus ''Canis'', the wolf is most Generalist and specialist species, specialized for Pack hunter, cooperativ ...

Björn Kurtén
Björn Olof Lennartson Kurtén (19 November 1924 – 28 December 1988) was a Finnish vertebrate paleontologist, belonging to the Swedish-speaking minority of his country. Early life and education Kurtén was born in Vaasa. Career He was a professor in paleontology at the University of Helsinki from 1972 up to his death in 1988. He also spent a year as lecturing guest professor at Harvard University in 1971. In ''Not from the Apes'' (1971) Kurtén argued that man's development has been separate from the apes since the Miocene, and that man did not descend from anthropoids, but rather the reverse: He was also the author of a series of books about modern man's encounter with Neanderthals, such as ''Dance of the Tiger'' (1978, 1980). When asked what genre these works belonged in, Kurtén coined the term '' paleofiction'' to describe his oeuvre. The genre was popularized by Jean M. Auel in her Earth's Children series of books. He received several awards for his books popularizin ... [...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 ...
