Equus Gallicus
Gallic horse (''Equus caballus gallicus'') is a prehistoric subspecies of ''Equus caballus'' (the horse) that lived in the Upper Paleolithic. It first appeared in the Aurignacian period because of climatic changes and roamed the territory of present-day France during the Gravettian and up to the end of the Solutrean. Its Fossil, fossils, dated from 40,000 to around 15,000 years BC, are close to those of ''Equus caballus germanicus'' (the Germanic horse) and may not correspond to a valid subspecies. First described by François Prat in 1968, it is around tall and differs from ''Equus caballus germanicus'' mainly in its dentition and slightly smaller size. Validity status There is no consensus among specialists as to the validity of the subspecies ''Equus caballus gallicus''. Based on paleontological discoveries at numerous sites in present-day France, such as Rock of Solutré, Solutré, Camiac-et-Saint-Denis, Camiac and La Quina, François Prat postulates that ''Equus caballus ga ...

Gallery Of Paleontology And Comparative Anatomy
The Gallery of Paleontology and Comparative Anatomy (in French, ''Galerie de Paléontologie et d'Anatomie comparée'') is a part of the French National Museum of Natural History (''Muséum national d'histoire naturelle'', MNHN). It is situated in the ''Jardin des plantes'' in Paris near the Gare d'Austerlitz. The Gallery of Comparative Anatomy (occupying the ground floor), holds nearly a thousand skeletons and interprets their organization and classification. The Gallery of Paleontology (occupying the first and second floor) presents a famous collection of fossil vertebrates, fossil invertebrates and fossil plants. Among the most appreciated pieces by the public is a series of dinosaur skeleton casts (''Diplodocus'', ''Iguanodon'', ''Allosaurus'', ''Carnotaurus'', ''Tarbosaurus'', ''Unenlagia'', ''Dromaeosaurus'', ''Bambiraptor'') but also a ''Tyrannosaurus'' skull (cast of specimen AMNH 5027), an authentic skull of ''Triceratops'', an authentic ''Compsognathus'' skeleton, and s ...

Equus (genus)
''Equus'' () is a genus of mammals in the perissodactyl family (biology), family Equidae, which includes wild horse, horses, Asinus, asses, and zebras. Within the Equidae, ''Equus'' is the only recognized Extant taxon, extant genus, comprising seven living species. Like Equidae more broadly, ''Equus'' has numerous extinct species known only from fossils. The genus originated in North America and dispersed into the Old World and South America during the Early and Middle Pleistocene. Equinae, Equines are odd-toed ungulates with slender legs, long heads, relatively long necks, manes (erect in most subspecies), and long tails. All species are herbivorous, and mostly grazers, with simpler digestive systems than Ruminantia, ruminants but able to subsist on lower-quality vegetation. While the domestic horse and donkey (along with their feral horse, feral descendants) exist worldwide, wild equine populations are limited to Africa and Asia. Wild equine social systems are in two forms; a H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steppe
In physical geography, a steppe () is an ecoregion characterized by grassland plains without closed forests except near rivers and lakes. Steppe biomes may include: * the montane grasslands and shrublands biome * the tropical and subtropical grasslands, savannas, and shrublands biome * the temperate grasslands, savannas, and shrublands biome A steppe is usually covered with grass and shrubs, depending on the season and latitude. The term ''steppe climate'' denotes a semi-arid climate, which is encountered in regions too dry to support a forest, but not dry enough to be a desert. Steppes are usually characterized by a semi-arid or continental climate. Temperature extremes can be recorded in the summer of up to and in winter of down to . Besides this major seasonal difference, fluctuations between day and night are also significant: in both the highlands of Mongolia and northern Nevada, can be reached during the day with sub-freezing readings at night.

Before Present
Before Present (BP) or "years before present (YBP)" is a time scale used mainly in archaeology, geology, and other scientific disciplines to specify when events occurred relative to the origin of practical radiocarbon dating in the 1950s. Because the "present" time changes, standard practice is to use 1January 1950 as the commencement date (epoch) of the age scale, with 1950 being labelled as the "standard year". The abbreviation "BP" has been interpreted retrospectively as "Before Physics", which refers to the time before nuclear weapons testing artificially altered the proportion of the carbon isotopes in the atmosphere, which scientists must account for when using radiocarbon dating for dates of origin that may fall after this year. In a convention that is not always observed, many sources restrict the use of BP dates to those produced with radiocarbon dating; the alternative notation "RCYBP" stands for the explicit "radio carbon years before present". Usage The BP scale is s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magdalenian
Magdalenian cultures (also Madelenian; ) are later cultures of the Upper Paleolithic and Mesolithic in western Europe. They date from around 17,000 to 12,000 years before present. It is named after the type site of Abri de la Madeleine, a rock shelter () located in the Vézère valley of Tursac in Dordogne, France. Édouard Lartet and Henry Christy originally termed the period ''L'âge du renne'' "the age of the reindeer". They conducted the first archaeological excavation of the type site, publishing in 1875. The Magdalenian is associated with reindeer hunters. Magdalenian sites contain extensive evidence for the hunting of red deer, wild horses, and other megafauna present in Europe toward the end of the Last Glacial Period. The culture was geographically widespread, and later Magdalenian sites stretched from Portugal in the west to Poland in the east, and as far north as France, the Channel Islands, England, and Wales. Besides la Madeleine, the chief stations of the Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Würm Glaciation
The Würm glaciation or Würm stage ( or ''Würm-Glazial'', colloquially often also ''Würmeiszeit'' or ''Würmzeit''; cf. ice age), usually referred to in the literature as the Würm (often spelled "Wurm"), was the last glacial period in the Alpine region. It is the youngest of the major glaciations of the region that extended beyond the Alps themselves. Like most of the other ice ages of the Pleistocene epoch, it is named after a river, in this case the Würm in Bavaria, a tributary of the Amper. The Würm ice age can be dated to about 115,000 to 11,700 years ago. Sources differ about the dates, depending on whether the long transition phases between the glacials and interglacials (warmer periods) are allocated to one or other of those periods. The average annual temperatures during the Würm ice age in the Alpine Foreland were below −3 °C (today +7 °C). That has been determined from changes in the vegetation ( pollen analysis), as well as differences in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pangaré
Pangaré is a coat Phenotypic_trait, trait found in some horses that features pale hair around the eyes, muzzle, and underside of the body. These pale areas can extend up to the flanks, throat and chest, behind the elbows, in front of the Stifle joint, stifle, and up the buttock. Animals with the pangaré trait are sometimes called "mealy" or "light-pointed". The color of these lighter areas depends on the underlying color and ranges from off-white to light tan. This type of coloration is most often found in breeds such as the Fjord horse, Exmoor Pony, and Haflinger (horse), Haflinger. Wild Equus (genus), equids like the Przewalski's horse, onager, African wild ass, kiang as well as the domestic donkey exhibit pangaré as a rule. Pangaré is thought to be a type of protective countershading. Horse foals are often born with "foal pangaré" or light points, especially over black haired areas, which they lose when they shed their foal coats. At one time, the Seal brown (horse), se ...

Dun Gene
The dun gene is a dilution gene that affects both red and black pigments in the equine coat color, coat color of a horse. The dun gene lightens most of the body while leaving the mane (horse), mane, tail, legs, and primitive markings the shade of the undiluted base coat color. A dun horse always has a dark dorsal stripe down the middle of its back, usually has a darker face and legs, and may have transverse striping across the shoulders or horizontal striping on the back of the forelegs. Body color depends on the underlying equine coat color genetics, coat color genetics. A classic "bay dun" is a gray-gold or tan, characterized by a body color ranging from sandy yellow to reddish brown. Duns with a chestnut (horse color), chestnut base may appear a light tan shade, and those with black horse, black base coloration are a smoky gray. Manes, tails, primitive markings, and other dark areas are usually the shade of the undiluted base coat color. The dun gene may interact with all other ...

Przewalski's Horse
Przewalski's horse (''Equus ferus przewalskii'' or ''Equus przewalskii''), also called the takhi, Mongolian wild horse or Dzungarian horse, is a rare and endangered wild horse originally native to the steppes of Central Asia. It is named after the Russian geographer and explorer Nikolay Przhevalsky. Once extinct in the wild, since the 1990s it has been Reintroduction, reintroduced to its native habitat in Mongolia in the Khustain Nuruu National Park, Takhin Tal Nature Reserve, and Khomiin Tal, as well as several other locales in Central Asia and Eastern Europe. Several genetic characteristics of Przewalski's horse differ from what is seen in modern domestic horses, indicating neither is an ancestor of the other. For example, Przewalski's horse has 33 chromosome pairs, compared to 32 for the domestic horse. Their ancestral lineages split from a common ancestor between 160,000 and 38,000 years ago, long before the domestication of the horse. Przewalski's horse was long considered ...

Cave Painting
In archaeology, cave paintings are a type of parietal art (which category also includes petroglyphs, or engravings), found on the wall or ceilings of caves. The term usually implies prehistoric art, prehistoric origin. These paintings were often created by ''Human, Homo sapiens'', but also Denisovan, Denisovans and Neanderthal, Neanderthals; other species in the same ''Homo'' genus. Discussion around prehistoric art is important in understanding the history of ''Homo sapiens'' and how human beings have come to have unique abstract thoughts. Some point to these prehistoric paintings as possible examples of creativity, spirituality, and sentimental thinking in prehistoric humans. The oldest known are more than 40,000 years old (art of the Upper Paleolithic) and found in the caves in the district of Maros (Sulawesi, Indonesia). The oldest are often constructed from hand stencils and simple geometric shapes.M. Aubert et al., "Pleistocene cave art from Sulawesi, Indonesia", ''Nature'' ...

Poaceae
Poaceae ( ), also called Gramineae ( ), is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos, the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, including staple foods from domesticated cereal crops such as maize, wheat, rice, oats, barley, and millet for people and as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials ( bamboo, thatch, and straw); oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
