Deinotheriidae
Deinotheriidae ("terrible beasts") is a family of prehistoric elephant-like proboscideans that lived during the Cenozoic era, first appearing in Africa, then spreading across southern Asia (Indo-Pakistan) and Europe. During that time, they changed very little, apart from growing much larger in size; by the late Miocene, they had become the largest land animals of their time. Their most distinctive features were the downward-curving tusks on the lower jaw. Deinotheres were not very diverse; the only three known genera are '' Chilgatherium'', ''Prodeinotherium'', and '' Deinotherium''. These form an evolutionary succession, with each new genus replacing the preceding one. Unlike the various mammoth and mastodont lineages, the deinotheres died out in the early Pleistocene, rather than continuing through the ice age. Description The body shape and proportions of deinotheres were very much like those of modern elephants. The legs were long, like modern elephants, but the skull ...

Deinotherium
''Deinotherium'' was a large elephant-like proboscidean that appeared in the Middle Miocene and survived until the Early Pleistocene. Although superficially resembling modern elephants, they had notably more flexible necks, limbs adapted to a more cursorial lifestyle as well as tusks that curved downwards and back. In addition, their tusks didn't emerge from the maxilla as in elephants but from the mandible. ''Deinotherium'' was a widespread genus, ranging from East Africa to the south to Europe and east to the Indian Subcontinent. They were browsing animals with a diet mainly consisting of leaves, and they most likely died out as forested areas were gradually replaced by open grassland during the latter half of the Neogene. History and naming ''Deinotherium'' has a long history, possibly dating back as early as the 17th century when a French surgeon named Matsorier found the bones of large animals in an area known as the "field of giants" near Lyon. Matsorier is said to have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prodeinotherium
''Prodeinotherium'' is an extinct representative of the family Deinotheriidae that lived in Africa, Europe, and Asia in the early and middle Miocene. ''Prodeinotherium'', meaning "before terrible beast", was first named in 1930, but soon after, the only species in it, ''P. hungaricum'', was reassigned to ''Deinotherium''. During the 1970s, however, the two genera were once again separated, with ''Prodeinotherium'' diagnosed to include ''Deinotherium bavaricum'' (=''P. hungaricum''), ''Deinotherium hobleyi'', and ''Deinotherium pentapotamiae'', which were separated based on geographic location. The three species are from Europe, Africa, and Asia, respectively. However, because of usage of few characters to separate them, only one species, ''P. bavaricum'', or many more species, including ''P. cuvieri'', ''P. orlovii'', and ''P. sinense'' may be possible. ''Prodeinotherium'' is one of three genera of the Deinotheriidae, the others being ''Chilgatherium'' from Africa, and ''Deinother ...

Proboscidea
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 the or ...

Elephant
Elephants are the largest existing land animals. Three living species are currently recognised: the African bush elephant, the African forest elephant, and the Asian elephant. They are the only surviving members of the family Elephantidae and the order Proboscidea. The order was formerly much more diverse during the Pleistocene, but most species became extinct during the Late Pleistocene epoch. Distinctive features of elephants include a long proboscis called a trunk, tusks, large ear flaps, pillar-like legs, and tough but sensitive skin. The trunk is used for breathing, bringing food and water to the mouth, and grasping objects. Tusks, which are derived from the incisor teeth, serve both as weapons and as tools for moving objects and digging. The large ear flaps assist in maintaining a constant body temperature as well as in communication. African elephants have larger ears and concave backs, whereas Asian elephants have smaller ears, and convex or level backs. Elephants ...

Chilgatherium
''Chilgatherium'' ('Chilga beast' after the locality in which it was found) is the earliest and most primitive representative of the family Deinotheriidae. It is known from late Oligocene (27- to 28-million-year-old) fossil teeth found in the Ethiopian district of Chilga. So far, only a few molar teeth have been found, but these are distinct enough that this animal can be identified with confidence. The teeth differ from those of ''Prodeinotherium'', ''Deinotherium'', and the various barytheres in various details, enough to show that this is a distinct type of animal, and has been placed in its own subfamily. Compared to later deinotheres, ''Chilgatherium'' was quite small, about tall at the shoulder and weighed about . It is not known if it shared the distinctive downward-curving tusks on the lower jaw that the later deinotheres had. ''Chilgatherium'' disappeared prior to the Early Miocene, where ''Prodeinotherium'' occurred, instead. References * Gugliotta, Guy (20 ...

Hippopotamus
The hippopotamus ( ; : hippopotamuses or hippopotami; ''Hippopotamus amphibius''), also called the hippo, common hippopotamus, or river hippopotamus, is a large semiaquatic mammal native to sub-Saharan Africa. It is one of only two extant species in the family Hippopotamidae, the other being the pygmy hippopotamus (''Choeropsis liberiensis'' or ''Hexaprotodon liberiensis''). Its name comes from the ancient Greek for "river horse" (). Aside from elephants and rhinos, the hippopotamus is the largest land mammal. It is also the largest extant land artiodactyl. Despite their physical resemblance to pigs and other terrestrial even-toed ungulates, the closest living relatives of the hippopotamids are cetaceans (whales, dolphins, porpoises, etc.), from which they diverged about 55 million years ago. Hippos are recognisable for their barrel-shaped torsos, wide-opening mouths with large canine tusks, nearly hairless bodies, pillar-like legs, and large size: adults average ...

Chilga
Chilga (Amharic: ጭልጋ ''č̣ilgā'') also Chelga, Ch'ilga is a woreda in Amhara Region, Ethiopia. It is named after its chief town Chilga (also known as Ayikel), an important stopping point on the historic Gondar-Sudan trade route. Part of the Maekelawi Gondar Zone, Chilga is bordered on the south by Takusa, on the west by Metemma, on the north by Tach Armachiho, on the northeast by Lay Armachiho, and on the east by Dembiya. Other towns in Chilga include Seraba and Wohni. Overview Elevations in this woreda range between 1000 and 1500 meters above sea level. Rivers include the Atbarah. A survey of the land in this woreda shows that 21.7% is arable or cultivable, 1.9% pasture, 22.3% forest or shrubland, and the remaining 54.1% is considered degraded or other. This survey covered more of the woreda than the sample enumeration performed by the Central Statistical Agency (CSA) in 2001. One notable landmark in this woreda is the archeological site at Chilga Kernet, which was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurasia
Eurasia (, ) is the largest continental area on Earth, comprising all of Europe and Asia. Primarily in the Northern and Eastern Hemispheres, it spans from the British Isles and the Iberian Peninsula in the west to the Japanese archipelago and the Russian Far East to the east. The continental landmass is bordered by the Atlantic Ocean and Africa to the west, the Pacific Ocean to the east, the Arctic Ocean to the north, and by Africa, the Mediterranean Sea, and the Indian Ocean to the south. The division between Europe and Asia as two continents is a historical social construct, as many of their borders are over land; thus, in some parts of the world, Eurasia is recognized as the largest of the six, five, or four continents on Earth. In geology, Eurasia is often considered as a single rigid megablock. However, the rigidity of Eurasia is debated based on paleomagnetic data. Eurasia covers around , or around 36.2% of the Earth's total land area. It is also home to the largest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
