Epivillafranchian
Villafranchian age ( ) is a period of geologic time (3.5–1.0 Ma) spanning the Late Pliocene and Early Pleistocene used more specifically with European Land Mammal Ages. Named by Italian geologist Lorenzo Pareto for a sequence of terrestrial sediments studied near Villafranca d'Asti, a town near Turin,http://archaeologywordsmith.com/lookup.php?category=&where=headword&terms=Villafranchian it succeeds the Ruscinian age, and is followed by the Galerian. The Villafranchian is sub-divided into six faunal units based on the localities of Triversa, Montopoli, Saint-Vallier, Olivola, Tasso and Farnetta.The Pleistocene Boundary and the Beginning of the Quaternary edited by John A. Van Couvering. Cambridge University Press 1997 A major division of both geological deposits ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pachycrocuta Brevirostris
''Pachycrocuta'' is an extinct genus of prehistoric hyenas. The largest and most well-researched species is ''Pachycrocuta brevirostris'', colloquially known as the giant short-faced hyena as it stood about at the shoulder and it is estimated to have averaged in weight, approaching the size of a lioness, making it the largest known hyena. ''Pachycrocuta'' first appeared during the late Miocene (Messinian, 7.2 to 5.3 million years agoA. Hill, G. Curtis, and R. Drake. 1986. Sedimentary stratigraphy of the Tugen Hills, Baringo, Kenya. Geological Society of America Special Publication 25:285-295). By 800,000 years ago, it became locally extinct in Europe and became completely extinct during the middle Pleistocene, 400,000 years ago. Taxonomy The first identified fossil of the short-faced hyena was discovered in Le Puy, Auvergne, France, in 1845 by French paleontologist Auguste Aymard. In 1850, French paleontologist Paul Gervais made it the holotype specimen of a new species, '' Hyae ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Least Weasel
The least weasel (''Mustela nivalis''), little weasel, common weasel, or simply weasel is the smallest member of the genus '' Mustela,'' family Mustelidae and order Carnivora. It is native to Eurasia, North America and North Africa, and has been introduced to New Zealand, Malta, Crete, the Azores, and São Tomé. It is classified as least concern by the IUCN, due to its wide distribution and large population throughout the Northern Hemisphere. The least weasel varies greatly in size over its range. The body is slender and elongated, and the legs and tail are relatively short. The colour varies geographically, as does the pelage type and length of tail. The dorsal surface, flanks, limbs and tail of the animal are usually some shade of brown while the underparts are white. The line delineating the boundary between the two colours is usually straight. At high altitudes and in the northern part of its range, the coat becomes pure white in winter. Eighteen subspecies are recognised. ...

Diachronism
In geology, a diachronism (Greek ''dia'', "through" + ''chronos'', "time" + ''-ism''), or diachronous deposit, is a sedimentary rock formation in which the material, although of a similar nature, varies in age with the place where it was deposited.Whitten F.G.A & Brooks J.R.V., (1972),''A Dictionary of Geology'', Penguin, Typically this occurs as a result of a marine transgression or regression, or the progressive development of a delta. As the shoreline advances or retreats, a succession of continuous deposits representing different environments (for example beach, shallow water, deeper water) may be left behind. Although each type of deposit (facies) may be continuous over a wide area, its age varies according to the position of the shoreline through time. An example is the sandy beds near the end of the lower Carboniferous of the west of England (the ''Drybrook sandstone'' of the Forest of Dean). Deposition of this began much later in the Bristol area than further north. The d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canis Etruscus
''Canis etruscus'', the Etruscan wolf, is an extinct species of canine that was endemic to Mediterranean Europe during the Early Pleistocene. The Etruscan wolf has been described as a small wolf-like dog. The Etruscan wolf has been accepted as the ancestor of '' C. mosbachensis'', that is the ancestor of the grey wolf (''C. lupus''), for a long time. Recent research has suggested that ''C. borjgali'' from Dmanisi has to be considered the ancestor of '' C. mosbachensis''. Taxonomy The fossil record for ancient vertebrates is composed of rarely occurring fragments, from which it is often impossible to obtain genetic material. Researchers are limited to morphologic analysis but it is difficult to estimate the intra-species and inter-species variations and relationships that existed between specimens across time and place. Some observations are debated by researchers who do not always agree, and hypotheses that are supported by some authors are challenged by others. Several specie ...

Equus Stenonis
''Equus stenonis'' or the Stenon zebra, is an extinct species of equine closely related to modern zebras and asses that inhabited Eurasia in the Pleistocene 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 .... The African species ''Equus koobiforensis'' and ''E. oldowayensis'' are closely related to ''E. stenonis''. Barron-Ortiz et al. (2019) resurrect the genus ''Allohippus'' for ''Equus stenonis'' based on the results of their cladistic analysis regarding the interrelationships of the genus ''Equus''.

Mammuthus Meridionalis
''Mammuthus meridionalis'', or the southern mammoth, is an extinct species of mammoth native to Europe and Central Asia from the Gelasian stage of the Early Pleistocene, living from 2.5–0.8 mya. Taxonomy The taxonomy of extinct elephants was complicated by the early 20th century, and in 1942, Henry Fairfield Osborn's posthumous monograph on the Proboscidea was published, wherein he used various taxon names that had previously been proposed for mammoth species, including replacing ''Mammuthus'' with ''Mammonteus'', as he believed the former name to be invalidly published. Mammoth taxonomy was simplified by various researchers from the 1970s onwards, all species were retained in the genus ''Mammuthus'', and many proposed differences between species were instead interpreted as intraspecific variation. The name ''Archidiskodon meridionalis'' is retained by some Russian researchers. Evolution The earliest known members of Proboscidea, the clade which contains modern eleph ...

Leptobos
''Leptobos'' is an extinct genus of large bovine, known from the Late Pliocene and Early Pleistocene of Eurasia, extending from the Iberian Peninsula to northern China. Species of ''Leptobos'' reached a weight up to 320 kg. ''Leptobos'' is considered to be closely related to the insular genus '' Epileptobos'' from the Pleistocene of Java'''', and is considered to be ancestral to ''Bison''. The dietary preference across the genus includes species that were browsers, grazers and mixed feeders (both browsing and grazing). The first appearance of ''Leptobos'' in Europe around 3.6-3.5 million years ago is considered to define the beginning of the Villafranchian Villafranchian age ( ) is a period of geologic time (3.5–1.0 Ma) spanning the Late Pliocene and Early Pleistocene used more specifically with European Land Mammal Ages.

Panthera Gombaszoegensis
''Panthera gombaszoegensis'', also known as the European jaguar, is a ''Panthera'' species that lived from about 2.0 to 0.35 million years ago in Europe. The first fossils were excavated in 1938 in Gombasek, Slovakia. More of its fossil remains were excavated from the Olivola site in Italy, while finds elsewhere in Italy were initially named ''Panthera toscana''. Later fossils were found in England, Germany, Spain, France, and the Netherlands. Sometimes it is recognized as a subspecies of ''Panthera onca'', the jaguar, as ''Panthera onca gombaszoegensis.'' Description European jaguars were larger than modern-day jaguars found in South America, such as Pantanal and Peruvian jaguars. With a bodyweight between 70 and 210 kg (154 to 463 lbs), they were therefore probably capable of bringing down larger prey. Like other ''Panthera'' species, they are thought to have been sexually dimorphic, with significantly larger males. History The ancestors of jaguars are thought to ...

Ursus Etruscus
''Ursus etruscus'' (the Etruscan bear) is an extinct species of bear, endemic to Europe, Asia and North Africa during the Pliocene through Pleistocene, living from ~5.3 million to 100,000 years ago. Taxonomy ''Ursus etruscus'' appears to have evolved from ''Ursus minimus'' and gave rise to the modern brown bear, ''Ursus arctos'', and the extinct cave bear, ''Ursus spelaeus''. The range of ''Ursus etruscus'' was mostly continental Europe with specimens also recovered in the Great Steppe region of Eurasia. Fossil evidence for ''Ursus etruscus'' was recovered in Palestine, Croatia, and Tuscany, Italy. Some scientists have proposed that the early, small variety of ''U. etruscus'' of the middle Villafranchian era survives in the form of the modern Asian black bear. Morphology Not unlike the brown bears of Europe in size, it had a full complement of premolars, a trait carried from the genus ''Ursavus''.

Moorhen
Moorhens—sometimes called marsh hens—are medium-sized water birds that are members of the rail family (Rallidae). Most species are placed in the genus ''Gallinula'', Latin for "little hen". They are close relatives of coots. They are often referred to as (black) gallinules. Recently, one of the species of ''Gallinula'' was found to have enough differences to form a new genus '' Paragallinula'' with the only species being the lesser moorhen (''Paragallinula angulata''). Two species from the Australian region, sometimes separated in , are called "native hens" (also native-hen or nativehen). The native hens differ visually by shorter, thicker and stubbier toes and bills, and longer tails that lack the white signal pattern of typical moorhens.Boles (2005) Description These rails are mostly brown and black with some white markings in plumage colour. Unlike many of the rails, they are usually easy to see because they feed in open water margins rather than hidden in reedbeds ...

Geologic Time
The geologic time scale, or geological time scale, (GTS) is a representation of time based on the rock record of Earth. It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (scientific branch of geology that aims to determine the age of rocks). It is used primarily by Earth scientists (including geologists, paleontologists, geophysicists, geochemists, and paleoclimatologists) to describe the timing and relationships of events in geologic history. The time scale has been developed through the study of rock layers and the observation of their relationships and identifying features such as lithologies, paleomagnetic properties, and fossils. The definition of standardized international units of geologic time is the responsibility of the International Commission on Stratigraphy (ICS), a constituent body of the International Union of Geological Sciences (IUGS), whose primary objective is to precisely define ...
