Prototocyon
''Prototocyon'' is an extinct genus of small omnivorous canid that lived during the Late Pliocene and Early Pleistocene. It is closely related to the living bat-eared fox (''Otocyon''). Taxonomy ''Prototocyon'' was named by Pohle (1928) and was assigned to Canidae by Carroll (1988). Old literature relates it to ''Vulpes bengalensis'', but not more modern literature (e.g. McKenna and Bell. A 2013 study stated that the genus "is only doubtfully distinct from ''Otocyon"'' the genus of the living bat-eared fox. Description ''Prototocyon'' was a small canine similar to the bat-eared fox in overall morphology and likely in habits as well. It differed from the modern bat-eared fox mainly in its more primitive dentition. Fossil distribution Fossil remains of ''P. curvipalatus'' were recovered from the early Pleistocene Upper Siwaliks horizon of the Siwalik Hills, India (Colbert 1935; Pilgrim 1932). Fossils of ''P recki'' have been found in the Olduvai Gorge area of Tanzania Tan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vulpini
Vulpini is a Tribe (biology), tribe which represents the fox-like taxon of the subfamily Caninae (the canines), and is sister to the dog-like tribe Canini (tribe), Canini. It comprises the 15 extant and 21 Extinction, extinct species found on all continents. Genera Taxonomy The taxonomy of Carnivora in general and Canidae in particular correlates with various diagnostic features of the dentition and basicranium. Regarding Vulpini, Tedford has remarked: The cladogram below is based on the phylogeny of Lindblad-Toh (2005) modified to incorporate recent findings on ''Vulpes''.

Bat-eared Fox
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 a Basal (phylogenetics), basal species of Canidae, canid. Fossil records indicate this canid first appeared during the Chibanian, middle Pleistocene. There are two separate populations of the bat-eared fox, each of which makes up a subspecies. 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. Other vernacular names include big-eared fox, black-eared fox, long-eared fox, Delalande's fox, cape fox, and motlosi. It is named for its large ears, which have a role in thermoregulation. It is a small canid, being of comparable size to the closely related cape fox and common raccoon dog. Its fur varies in color depending on the subspecies, but is generally tan-colored and has guard hairs of a grey agouti (coloration), agouti ...

Pliocene
The Pliocene ( ; also Pleiocene) is the epoch (geology), epoch in the geologic time scale that extends from 5.33 to 2.58See the 2014 version of the ICS geologic time scale million years ago (Ma). It is the second and most recent epoch of the Neogene Period in the Cenozoic, Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. Prior to the 2009 revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian Stage, which lasted from 2.59 to 1.81 Ma, and is now included in the Pleistocene. As with other older geologic periods, the Stratum, geological strata that define the start and end are well-identified but the exact dates of the start a ...

Olduvai Gorge
The Olduvai Gorge or Oldupai Gorge in Tanzania is one of the most important paleoanthropology, paleoanthropological localities in the world; the many sites exposed by the gorge have proven invaluable in furthering understanding of early human evolution. A steep-sided ravine in the Great Rift Valley that stretches across East Africa, it is about 48 km long, and is located in the eastern Serengeti Plains within the Ngorongoro Conservation Area in the Olbalbal ward located in Ngorongoro District of Arusha Region, about from Laetoli, another important archaeological locality of early human occupation. The British/Kenyan paleoanthropologist-archeologist team of Mary Leakey, Mary and Louis Leakey established excavation and research programs at Olduvai Gorge that achieved great advances in human knowledge. The site is registered as one of the National Historic Sites of Tanzania. The gorge takes its name from the Maasai language, Maasai word ''oldupai'' which means "the place of the ...

Fossil Taxa Described In 1880
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Though the fossil record is incomplete, numerous studies have demonstrated that there is enough information available to give a good understanding of the pattern of diversification of life on Earth. In addition, the record can predict and fill gaps such as the discovery of ''Tiktaalik'' in the arctic of Canada. Paleontology includes the study of fossils: their age, method of formation, and evolutionary significance. Specimens are sometimes considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years to 4.1 billion years old. Early edition, published online before print. The ob ...

Pleistocene Mammals Of Africa
The Pleistocene ( ; referred to colloquially as the ''Ice Age'') is the geological epoch that lasted from 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 () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold glacial periods and warmer interglacials, with the sea levels being up to lower than ...

Prehistoric Canines
Prehistory, also called pre-literary history, is the period of human history between the first known use of stone tools by hominins 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 years ago. It took thousands of years for writing systems to be widely adopted, with writing having spread to almost all cultures by the 19th century. The end of prehistory therefore came at different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. It is based on an old conception of history that without written records there could be no history. The most common conception today is that history is based on evidence, however the concept of prehistory hasn't been completely discarded. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
