Vulpini
Vulpini is a taxonomic rank which represents the fox-like tribe of the subfamily Caninae (the canines), and is sister to the dog-like tribe Canini. Genera Taxonomy The taxonomy of Carnivora in general and Canidae in particular correlates with various diagnostic features of the dentition Dentition pertains to the development of teeth and their arrangement in the mouth. In particular, it is the characteristic arrangement, kind, and number of teeth in a given species at a given age. That is, the number, type, and morpho-physiolo ... and basicranium. Rergarding Vulpini, Tedford has remarked: The cladogram below is based on the phylogeny of Lindblad-Toh (2005) modified to incorporate recent findings on ''Vulpes''.

Richard H
Richard is a male given name. It originates, via Old French, from Old Frankish and is a compound of the words descending from Proto-Germanic ''*rīk-'' 'ruler, leader, king' and ''*hardu-'' 'strong, brave, hardy', and it therefore means 'strong in rule'. Nicknames include "Richie", "Dick", "Dickon", " Dickie", "Rich", "Rick", "Rico", "Ricky", and more. Richard is a common English, German and French male name. It's also used in many more languages, particularly Germanic, such as Norwegian, Danish, Swedish, Icelandic, and Dutch, as well as other languages including Irish, Scottish, Welsh and Finnish. Richard is cognate with variants of the name in other European languages, such as the Swedish "Rickard", the Catalan "Ricard" and the Italian "Riccardo", among others (see comprehensive variant list below).

Urocyon
''Urocyon'' (Greek: "tailed dog") is a genus of Canidae which includes the gray fox (''Urocyon cinereoargenteus'') and the island fox (''Urocyon littoralis''). These two fox species are found in the Western Hemisphere. Whole genome sequencing indicates that ''Urocyon'' is the most basal genus of the living canids. Fossils of what is believed to be the ancestor of the gray fox, ''Urocyon progressus'', have been found in Kansas and date to the Upper Pliocene, with some undescribed specimens dating even older. Extant species Cozumel fox The Cozumel fox is a critically endangered or extinct small gray fox found on the island of Cozumel, Mexico. The last reported sighting was in 2001, but surveys focusing on this species have not yet been carried out. The Cozumel fox has not been scientifically described, but is a dwarf Dwarf or dwarves may refer to: Common uses *Dwarf (folklore), a being from Germanic mythology and folklore * Dwarf, a person or animal with dwarfism Arts, ...

Prehistoric Canids
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] |
Miocene Mammals Of North America
The Miocene ( ) is the first geological epoch of the Neogene The Neogene ( ), informally Upper Tertiary or Late Tertiary, is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period million years ago ( Mya) to the beginning of the present Quaternary Period Mya. ... Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protocyon
''Protocyon'' is an extinct genus of large canid endemic to South and North America during the Late Pleistocene living from 781 to 12thousand years ago. Description ''Protocyon'' was a hypercarnivore, suggested by its dental adaptations. Like many other large canids, it was most likely a pack hunter. It hunted the medium-sized grazers and browsers, and bite marks on fossils suggest that it may have hunted '' Glyptotherium''. The find of a molar tooth found in Santa Vitória do Palmar in Brazil suggests a weight of between for this particular specimen. , modest in size compared to other canids including the dire wolf, despite its modest size isotopic analysis shows a dietary overlap with Smilodon populator, which implies it actively hunted much larger prey animals since S. populator weighed at least 400kg. Taxonomy ''Protocyon'' was named by Giebel in 1855 and assigned to Canidae by Carroll in 1988. A member of the Cerdocyonina lineage, its closest living relative might be the bus ...

Otocyon
The bat-eared fox (''Otocyon megalotis'') is a species of fox found on the African savanna. It is the only extant species of the genus ''Otocyon'' and considered a basal canid species. Fossil records indicate this canid first appeared during the middle Pleistocene. It is named for its large ears, which have a role in thermoregulation. The bat referred to in its colloquial name is possibly the Egyptian slit-faced bat (''Nycteris thebaica''), which is abundant in the region and has very large ears. Although not commonly used, other vernacular names include big-eared fox, black-eared fox, long-eared fox, Delalande's fox, cape fox, and motlosi. Systematics and evolution The bat-eared fox is the only living species of the genus ''Otocyon''. Its scientific name, given by Anselme Gaëtan Desmarest, was initially ''Canis megalotis'' (due to its close resemblance to jackals), and later changed by Salomon Müller which placed it in its own genus, ''Otocyon''; its huge ears and different ...

Dentition
Dentition pertains to the development of teeth and their arrangement in the mouth. In particular, it is the characteristic arrangement, kind, and number of teeth in a given species at a given age. That is, the number, type, and morpho-physiology (that is, the relationship between the shape and form of the tooth in question and its inferred function) of the teeth of an animal. Animals whose teeth are all of the same type, such as most non-mammalian vertebrates, are said to have '' homodont'' dentition, whereas those whose teeth differ morphologically are said to have '' heterodont'' dentition. The dentition of animals with two successions of teeth (deciduous, permanent) is referred to as ''diphyodont'', while the dentition of animals with only one set of teeth throughout life is ''monophyodont''. The dentition of animals in which the teeth are continuously discarded and replaced throughout life is termed ''polyphyodont''. The dentition of animals in which the teeth are set in so ...
