Metaschizotherium
''Metaschizotherium'' is an extinct genus that belongs to the family Chalicotheriidae, which was a group of herbivorous perissodactyl ("odd-toed") mammals. Though found primarily in Europe, fragmentary remains suggest that their range extended into Asia. Several other species have been described under ''Metaschizotherium'' in the past, including the African ''M. transvaalensis'', but they have been transferred to other genera, such as ''Ancylotherium''. The entire genus has been considered synonymous with ''Ancylotherium'' in the past, but nowadays the two are generally found to be distinct. This genus is typically associated with areas of closed, moist forest, where it fed on relatively soft leaves and shoots compared to a more abrasive diet of twigs and bark.

Chalicotheres
Chalicotheres (from Greek language, Greek ''wikt:χάλιξ, chalix'', "gravel" and ''wikt:θηρίον, therion'', "beast") are an extinct clade of herbivorous, odd-toed ungulate (perissodactyl) mammals that lived in North America, Eurasia, and Africa from the Eocene, Middle Eocene until the Early Pleistocene, existing from 48.6 to 1.806 Annum, mya. They are one of the five major Evolutionary radiation, radiations of perissodactyls, with three groups living (Equidae, horses, plus the extinct Palaeotheriidae, paleotheres; Rhinoceros, rhinoceroses; Tapiroidea, tapirs), and two extinct (Brontotheriidae, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Miocene
The Miocene ( ) is the first geological epoch of the Neogene 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, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.

Ancylotherium
''Ancylotherium'' (from Greek, meaning "hooked beast") is an extinct genus of the family Chalicotheriidae, subfamily Schizotheriinae, endemic to Europe, Asia, and Africa during the Late Miocene-Early Pleistocene (9.0—1.8 mya), existing for approximately . Taxonomy ''Ancylotherium'' was named by Gaudry (1863) and was assigned to Chalicotheriidae by Carroll (1988); and to Schizotheriinae by Geraads et al. (2007). Description With some individuals reaching high at the shoulder and a weight of , ''Ancylotherium'' was relatively large, and was built rather like a goat. Individuals varied considerably in size, and the genus may have been sexually dimorphic, like many other chalicotheres. While it had the typical long forelimbs and short hind limbs of a chalicothere, like other schizotheriines, it did not walk on its knuckles. It was similar to the North American genus ''Moropus''. In at least some individuals of ''A. pentelicum'' the frontal bone of the skull is inflated to form a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinct Mammals Of Europe
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Moropus
''Moropus'' (meaning "slow foot") is an extinct genus of large perissodactyl ("odd-toed" ungulate) mammal in the chalicothere family. They were endemic to North America during the Miocene from ~20.4—13.6 Mya, existing for approximately . ''Moropus'' belonged to the schizotheriine subfamily of chalicotheres, and has the best fossil record of any member of this group; numbers of individuals, including complete skeletons, have been found. The closest extant relatives of ''Moropus'' are other perissodactyls: Equus (genus), horses, Rhinoceros, rhinos, and tapirs. Description Like other 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 Plei ...s, ''Moropus'' differed from typical ungulates in having large claws, rather than hooves, on the feet.

Shoots
In botany, a plant shoot consists of any plant stem together with its appendages, leaves and lateral buds, flowering stems, and flower buds. The new growth from seed germination that grows upward is a shoot where leaves will develop. In the spring, perennial plant shoots are the new growth that grows from the ground in herbaceous plants or the new stem or flower growth that grows on woody plants. In everyday speech, shoots are often synonymous with stems. Stems, which are an integral component of shoots, provide an axis for buds, fruits, and leaves. Young shoots are often eaten by animals because the fibers in the new growth have not yet completed secondary cell wall development, making the young shoots softer and easier to chew and digest. As shoots grow and age, the cells develop secondary cell walls that have a hard and tough structure. Some plants (e.g. bracken) produce toxins that make their shoots inedible or less palatable.

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.

Asia
Asia (, ) is one of the world's most notable geographical regions, which is either considered a continent in its own right or a subcontinent of Eurasia, which shares the continental landmass of Afro-Eurasia with Africa. Asia covers an area of , about 30% of Earth's total land area and 8.7% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constitute roughly 60% of the world's population. In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, linguistic, ...

Gustav Heinrich Ralph Von Koenigswald
Gustav Heinrich Ralph (often cited as G. H. R.) von Koenigswald (13 November 1902 – 10 July 1982) was a German-Dutch paleontologist and geologist who conducted research on hominins, including ''Homo erectus''. His discoveries and studies of hominid fossils in Java and his studies of other important fossils of south-eastern Asia firmly established his reputation as one of the leading figures of 20th-century paleo-anthropology. Biography Von Koenigswald was born in Berlin in a period of intense interest and rapid growth in the study of evolution. He began his fossil vertebrate collection when he was fifteen with the acquisition of a rhinoceros molar during an excursion to Mauer, Germany. He subsequently studied geology and paleontology at Berlin, Tübingen, Cologne and Munich. Java Von Koenigswald's teacher Ferdinand Broili had good contacts with the Dutch geologists Karl Martin and Reinout Willem van Bemmelen. Through these contacts Von Koenigswald c ...

Perissodactyl
Odd-toed ungulates, mammals which constitute the taxonomic order Perissodactyla (, ), are animals—ungulates—who have reduced the weight-bearing toes to three (rhinoceroses and tapirs, with tapirs still using four toes on the front legs) or one (equines, third toe) of the five original toes. The non-weight-bearing toes are either present, absent, vestigial, or positioned posteriorly. By contrast, the even-toed ungulates bear most of their weight equally on four or two (an even number) of the five toes: their third and fourth toes. Another difference between the two is that odd-toed ungulates digest plant cellulose in their intestines rather than in one or more stomach chambers as even-toed ungulates, with the exception of Suina, do. The order includes about 17 species divided into three families: Equidae (horses, asses, and zebras), Rhinocerotidae (rhinoceroses), and Tapiridae (tapirs). Despite their very different appearances, they were recognized as related families in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
