Sansan Paleontological Site
The Sansan paleontological site (locally au Campané) is a Miocene fossil deposit in Sansan, Gers, Sansan, in the department (France), French department of Gers. Searched by Edouard Lartet until 1847, it was considered useful for Science and is registered by the Geoheritage, Inventaire national du Patrimoine Géologique (InPG) as an international-level site. It constitutes one of the most important Middle Cenozoic deposits and is well known in palaeontological circles. The National Museum of Natural History, France, National Museum of Natural History bought of terrain in 1848 and oversee any research on the site since then. The research stopped in 1999. The site has been open to the public since 2018. Location The paleontological site is located inside the commune of Sansan, Gers, Sansan, on the Campané hill at above sea level, in the Gers department, south of Auch. The hill and its surroundings were historically called "''Camp de las hossos''". Recent history The deposits w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fossil Site
This list of fossil sites is a worldwide list of localities known well for the presence of fossils. Some entries in this list are notable for a single, unique find, while others are notable for the large number of fossils found there. Many of the entries in this list are considered Lagerstätten (sedimentary deposits that exhibits extraordinary fossils with exceptional preservation—sometimes including preserved soft tissues). Lagerstätten are indicated by a note () in the noteworthiness column. Fossils may be found either associated with a geological formation or at a single geographic site. Geological formations consist of rock that was deposited during a specific period of time. They usually extend for large areas, and sometimes there are different important sites in which the same formation is exposed. Such sites may have separate entries if they are considered to be more notable than the formation as a whole. In contrast, extensive formations associated with large areas m ...

Pliopithecus
''Pliopithecus'' {meaning "more ape") is a genus of extinct primates of the Miocene. It was discovered in 1837 by Édouard Lartet (1801–1871) in France, with fossils subsequently discovered in Switzerland, Slovakia and Spain. ''Pliopithecus'' had a similar size and form to modern gibbons, to which it may be related, although it is probably not a direct ancestor. It had long limbs, hands, and feet, and may have been able to brachiate, swinging between trees using its arms. Unlike gibbons, it had a short tail, and only partial stereoscopic vision. They appear to have originated in Asia and extended their range into Europe between 20 and 17 million years ago. Begun and Harrison list the following species within the genus: * ''Pliopithecus antiquus'' * ''Pliopithecus bii'' * ''Pliopithecus canmatensis'' * ''Pliopithecus platyodon'' * '' Pliopithecus vindobonensis'' * ''Pliopithecus zhanxiangi'' ''Pliopithecus antiquus'' has been referred to previously as ''P. piveteaui''.

Vespertilionidae
Vespertilionidae is a family of microbats, of the order Chiroptera, flying, insect-eating mammals variously described as the common, vesper, or simple nosed bats. The vespertilionid family is the most diverse and widely distributed of bat families, specialised in many forms to occupy a range of habitats and ecological circumstances, and it is frequently observed or the subject of research. The facial features of the species are often simple, as they mainly rely on vocally emitted echolocation. The tails of the species are enclosed by the lower flight membranes between the legs. Over 300 species are distributed all over the world, on every continent except Antarctica. It owes its name to the genus '' Vespertilio'', which takes its name from a word for bat, ', derived from the Latin term ' meaning 'evening'; they are termed "evening bats" and were once referred to as "evening birds". (The term "evening bat" also often refers more specifically to one of the species, ''Nycticeius hume ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Anisodon
''Anisodon'' (Greek: "unequal" (anisos), "teeth" (odontes)) is an extinct genus of chalicothere that lived in Europe during the late Miocene. It stood at about 150 cm and weighed around 600 kg. It is thought that the animal's clawed forelimbs would have allowed it to pull down tree branches in order to browse, as well as deter Miocene predators such as bear-dogs and saber-toothed cats Sabretooth or sabertooth may refer to: Animals * Saber-toothed cat, several prehistoric felines ** '' Smilodon'', a prehistoric genus of felidae * Sabertooth fish, a deep-sea fish found in the tropics ** Sabre-toothed blenny, ''Aspidontus taen ....

Chalicothere
Chalicotheres (from Greek '' chalix'', "gravel" and '' therion'', "beast") are an extinct clade of herbivorous, odd-toed ungulate (perissodactyl) mammals that lived in North America, Eurasia, and Africa from the Middle Eocene until the Early Pleistocene, existing from 48.6 to 1.806 mya. They are one of the five major radiations of perissodactyls, with three groups living (horses, plus the extinct paleotheres; rhinoceroses; tapirs), and two extinct (brontotheres and chalicotheres). Description Unlike modern perissodactyls, chalicotheres had clawed feet. They had longer forelimbs and shorter hind limbs, lower incisors that cropped food against a toothless pad in the upper jaw, low-crowned molar teeth, and were browsers on trees and shrubs throughout their history. They evolved in two different directions, which became separate subfamilies, the Schizotheriinae and the Chalicotheriinae. Schizotherine chalicotheres such as '' Moropus'' lived in a variety of forest, woodlan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphicyon
''Amphicyon'' ("ambiguous dog") is an extinct genus of large carnivorous bone-crushing mammals, popularly known as bear dogs, of the family Amphicyonidae, subfamily Amphicyoninae, from the Burdigalian Epoch until the late Pliocene, with the creature having bear-like and dog-like features. They ranged over North America, Europe, Asia, and Africa from 16.9 to 2.6 Ma ago, existing for approximately . Morphology ''Amphicyon'' was the typical bear-dog amphicyonid with morphology similar to both bears and dogs. With its robust build and maximum length of 2.5 m (8 ft), the largest species looked more like a bear than a dog. It had a large heavy tail, thick neck, robust limbs and teeth like a wolf. It was probably an omnivore with a lifestyle comparable to that of the brown bear. The ''Amphicyon'' was very large for predators of its time but this advantage eventually became a disadvantage because its large body mass was too large to take faster prey. ''A. major'' has b ...

Proboscidean
The Proboscidea (; , ) are a taxonomic order of afrotherian mammals containing one living family (Elephantidae) and several extinct families. First described by J. Illiger in 1811, it encompasses the elephants and their close relatives. From the mid-Miocene onwards, most proboscideans were very large. The largest land mammal of all time may have been a proboscidean; '' Palaeoloxodon namadicus'' was up to at the shoulder and may have weighed up to , almost double the weight of some sauropods like '' Diplodocus carnegii''. The largest extant proboscidean is the African bush elephant, with a record of size of at the shoulder and . In addition to their enormous size, later proboscideans are distinguished by tusks and long, muscular trunks, which were less developed or absent in early proboscideans. Three species of elephant are currently recognised: the African bush elephant, the African forest elephant, and the Asian elephant. Elephantidae is the only surviving family of ...

Evolution Theory
Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes, which are passed on from parent to offspring during reproduction. Variation tends to exist within any given population as a result of genetic mutation and recombination. Evolution occurs when evolutionary processes such as natural selection (including sexual selection) and genetic drift act on this variation, resulting in certain characteristics becoming more common or more rare within a population. The evolutionary pressures that determine whether a characteristic is common or rare within a population constantly change, resulting in a change in heritable characteristics arising over successive generations. It is this process of evolution that has given rise to biodiversity at every level of biological organisation, including the levels of species, individual organisms, and molecules.
