Palaeomerycidae
The Palaeomerycidae are an extinct family of ruminants in the order Artiodactyla. Palaeomerycids lived in North America, Europe, Africa and Asia from 33 to 4.9 million years ago (from the Late Eocene to Pliocene epochs), existing for about 28 million years; one species was also reported from South America, but its identity as a palaeomerycid was subsequently disputed. Specimens of '' Amphitragulus'', the earliest known genus, have been found in Aragon (Spain), Ronheim (Germany), Sardinia (Italy), France, and Kazakhstan and range from 33 to 15.97 million years old. Fossils of '' Lagomeryx'' and ''Palaeomeryx feignouxi'' were recovered in Germany and Slovakia from the Middle Eocene. The oldest known North American specimen, '' Barbouromeryx'', was discovered in Scotts Bluff, Nebraska, and estimated at 23.03 million years old. Palaeomerycids such as ''Cranioceras'' and other Dromomerycinae continued to live in North America until the early Pliocene. Description Palaeomerycids w ...

Palaeomeryx
''Palaeomeryx'' is an extinct genus of Artiodactyla, of the family Palaeomerycidae, endemic to Europe and Asia from the Miocene epoch, 16.9 – 7.25 Ma, existing for approximately . Taxonomy ''Palaeomeryx'' was named by von Meyer (1834). It is the type genus of Palaeomerycidae, Palaeomerycinae. It was assigned to Palaeomerycidae by Carroll (1988) and Sach and Heizmann (2001); and to Palaeomerycinae by Prothero and Liter (2007).D. R. Prothero and M. R. Liter. 2007.

Giraffidae
The Giraffidae are a family of ruminant artiodactyl mammals that share a common ancestor with deer and bovids. This family, once a diverse group spread throughout Eurasia and Africa, presently comprises only two extant genera, the giraffe (one or more species of ''Giraffa'', depending on taxonomic interpretation) and the okapi (the only known species of ''Okapia''). Both are confined to sub-Saharan Africa: the giraffe to the open savannas, and the okapi to the dense rainforest of the Congo. The two genera look very different on first sight, but share a number of common features, including a long, dark-coloured tongue, lobed canine teeth, and horns covered in skin, called ossicones. Taxonomy Evolutionary background The giraffids are ruminants of the clade Pecora. Other extant pecorans are the families Antilocapridae (pronghorns), Cervidae (deer), Moschidae (musk deer), and Bovidae (cattle, goats and sheep, wildebeests and allies, and antelopes).

Lagomeryx
''Lagomeryx'' is a genus of prehistoric ungulate that lived in Eurasia from the lower to middle Miocene. Fossil remains were found in Europe and Asia. Description This animal looked not very different from present chevrotains, but possessed two small horns on the skull. Its size was very small (''Lagomeryx'' means "rabbit ruminant" in reference to the size). The smallest species, ''Lagomeryx pumilio'', was just as big as a hare. ''Lagomeryx'' and his close relatives (such as '' Ligeromeryx'' and '' Stephanocemas'') had many primitive features resembling those of moschoid ancestors, such as the presence of two elongated canines in adult males. The cranial appendages were formed by a relatively short pedicle. In smaller species (such as '' L. pumilio'') these horns were very tiny, and did not exceed the height of 1.5 centimeters.

Ruminants
Ruminants ( suborder Ruminantia) are hoofed herbivorous grazing or browsing mammals that are able to acquire nutrients from plant-based food by fermenting it in a specialized stomach prior to digestion, principally through microbial actions. The process, which takes place in the front part of the digestive system and therefore is called foregut fermentation, typically requires the fermented ingesta (known as cud) to be regurgitated and chewed again. The process of rechewing the cud to further break down plant matter and stimulate digestion is called rumination. The word "ruminant" comes from the Latin ''ruminare'', which means "to chew over again". The roughly 200 species of ruminants include both domestic and wild species. Ruminating mammals include cattle, all domesticated and wild bovines, goats, sheep, giraffes, deer, gazelles, and antelopes.Fowler, M.E.

Artiodactyla
The even-toed ungulates (Artiodactyla , ) are ungulates—hoofed animals—which bear weight equally on two (an even number) of their five toes: the third and fourth. The other three toes are either present, absent, vestigial, or pointing posteriorly. By contrast, odd-toed ungulates bear weight on an odd number of the five toes. Another difference between the two is that many other even-toed ungulates (with the exception of Suina) digest plant cellulose in one or more stomach chambers rather than in their intestine as the odd-toed ungulates do. Cetaceans (whales, dolphins, and porpoises) evolved from even-toed ungulates, and are therefore often classified under the same taxonomic branch because a species cannot outgrow its evolutionary ancestry; some modern taxonomists combine the two under the name Cetartiodactyla , while others opt to include cetaceans in the already-existing Artiodactyla. The roughly 270 land-based even-toed ungulate species include pigs, peccaries, hippopo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Richard Lydekker
Richard Lydekker (; 25 July 1849 – 16 April 1915) was an English naturalist, geologist and writer of numerous books on natural history. Biography Richard Lydekker was born at Tavistock Square in London. His father was Gerard Wolfe Lydekker, a barrister-at-law with Dutch ancestry. The family moved to Harpenden Lodge soon after Richard's birth. He was educated at Trinity College, Cambridge, where he took a first-class in the Natural Science tripos (1872). In 1874 he joined the Geological Survey of India and made studies of the vertebrate palaeontology of northern India (especially Kashmir). He remained in this post until the death of his father in 1881. His main work in India was on the Siwalik palaeofauna; it was published in ''Palaeontologia Indica''. He was responsible for the cataloguing of the fossil mammals, reptiles, and birds in the Natural History Museum (10 vols., 1891). He named a variety of taxa including the golden-bellied mangabey; as a taxon authority he is nam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kazakhstan
Kazakhstan, officially the Republic of Kazakhstan, is a transcontinental country located mainly in Central Asia and partly in Eastern Europe. It borders Russia to the north and west, China to the east, Kyrgyzstan to the southeast, Uzbekistan to the south, and Turkmenistan to the southwest, with a coastline along the Caspian Sea. Its capital is Astana, known as Nur-Sultan from 2019 to 2022. Almaty, Kazakhstan's largest city, was the country's capital until 1997. Kazakhstan is the world's largest landlocked country, the largest and northernmost Muslim-majority country by land area, and the ninth-largest country in the world. It has a population of 19 million people, and one of the lowest population densities in the world, at fewer than 6 people per square kilometre (15 people per square mile). The country dominates Central Asia economically and politically, generating 60 percent of the region's GDP, primarily through its oil and gas industry; it also has vast mineral ...

Scotts Bluff, Nebraska
Scottsbluff is a city in Scotts Bluff County, in the western part of the state of Nebraska, in the Great Plains region of the United States. The population was 14,436 at the 2020 census. Scottsbluff is the largest city in the Nebraska Panhandle, and the 13th largest city in Nebraska. Scottsbluff was founded in 1899 across the North Platte River from its namesake, a bluff that is now a U.S. National Park called Scotts Bluff National Monument. The monument was named after Hiram Scott (1805–1828), a fur trader with the Rocky Mountain Fur Company who was found dead in the vicinity on the return trip from a fur expedition. The smaller town of Gering had been founded south of the river in 1887. The two cities have since grown together to form the 7th largest urban area (the Scottsbluff Micropolitan Statistical Area) in Nebraska. History Scottsbluff was founded in 1899 by the Lincoln Land Company, a subsidiary of the Burlington Railroad. By 1900, the Burlington Railroad laid t ...
