Hippopotamus Gorgops
''Hippopotamus gorgops'' is an extinct species of hippopotamus. It first appeared in Africa during the late Pliocene, and eventually migrated into Europe (where its fossils were first discovered) during the early Pleistocene. It became extinct during the Middle Pleistocene. Fossil records found at Ubeidiya, Israel suggested that they migrated out of Africa around 1.6 million years ago. Some have speculated that ''H. gorgops'' and '' H. behemoth'' are actually the same species given their similar sizes and where they have been found. Taxonomy With an estimated length of , a shoulder height of , and a weight of 3,900-4,500 kg (8,600-9,900 lb), ''H. gorgops'' was larger than its living relative, ''H. amphibius''. Another feature setting it apart from ''H. amphibius'' was the placement of its eyes. Modern hippos have eyes placed high on the skull The skull is a bone protective cavity for the brain. The skull is composed of four types of bone i.e., cranial bones, facial bones, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilhelm Otto Dietrich
Wilhelm Otto Dietrich (30 July 1881 – 26 March 1964) was a German (later East German) paleontologist who took a special interest in the study of Tertiary and Quaternary mammals. He was a curator of paleontology at the Natural History Museum, Berlin. Dietrich was born in Senden near Ulm to mill manager Otto and Maria née Kramer. After studying at the Ulm gymnasium he joined the Technical University at Stuttgart before transferring to the University of Tübingen in 1901. He studied geology and paleontology and received a doctorate in 1903 under Ernst Koken. He studied petrology at Freburg and then worked from 1904 as an assistant to Ernst Anton Wülfing in Danzig. He developed otosclerosis in 1907 and had to move to Switzerland for treatment but he progressively lost hearing and became completely deaf. He became an assistant at Stuttgart under Eberhard Fraas and joined an excavation at Steinheim-on-Murr where the dig discovered a giant deer and a mammoth (''Elephas primigenius'') ...

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 ...

Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

Hippopotamus Behemoth
''Hippopotamus behemoth'' is an extinct species of hippopotamus from the Early Pleistocene of the Levant The Levant () is an approximate historical geographical term referring to a large area in the Eastern Mediterranean region of Western Asia. In its narrowest sense, which is in use today in archaeology and other cultural contexts, it is .... Fossils of it, the modern hippopotamus '' H. amphibius'', and its probable ancestor, '' H. gorgops'', are found in the ‘Ubeidiya site in the southern Levant.Rabinovich, Rivka, and Rebecca Biton. "The Early–Middle Pleistocene faunal assemblages of Gesher Benot Ya ‘aqov: Inter-site variability." Journal of Human Evolution 60.4 (2011): 357-374. ''H. behemoth'' differs from ''H. gorgops'' in having more elongated feet, and being somewhat smaller.Prothero, Donald R., and Scott E. Foss, eds. The evolution of artiodactyls. JHU Press, 2007. Some experts consider these differences to be too slight to justify separating the two ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skull
The skull is a bone protective cavity for the brain. The skull is composed of four types of bone i.e., cranial bones, facial bones, ear ossicles and hyoid bone. However two parts are more prominent: the cranium and the mandible. In humans, these two parts are the neurocranium and the viscerocranium ( facial skeleton) that includes the mandible as its largest bone. The skull forms the anterior-most portion of the skeleton and is a product of cephalisation—housing the brain, and several sensory structures such as the eyes, ears, nose, and mouth. In humans these sensory structures are part of the facial skeleton. Functions of the skull include protection of the brain, fixing the distance between the eyes to allow stereoscopic vision, and fixing the position of the ears to enable sound localisation of the direction and distance of sounds. In some animals, such as horned ungulates (mammals with hooves), the skull also has a defensive function by providing the mount (on the front ...

Terrassa
Terrassa (, es, Tarrasa) is a city in the east central region of Catalonia, Spain, in the province of Barcelona, ''comarca'' of Vallès Occidental, of which it is the co-capital along with Sabadell. The name ''Terrassa'' derives from Latin ''Terracia'', either from earlier ''Terracium castellum'' (“earthen castle”), or meaning "terrace", "area of flat land". It is the site of Roman Egara, a former Visigothic bishopric, which became a Latin Catholic titular see. Since 2004, it is again the see of a bishopric. The city is located in the Catalan Prelitoral depression (Depressió Prelitoral), at the feet of the Prelitoral mountain range (Natural reserve of Sant Llorenç del Munt) and the average altitude of the city is 277 meters above sea level. It is 20 and 18 kilometres from Barcelona and Montserrat respectively. Terrassa is the third largest city in the province of Barcelona, after Barcelona and L’Hospitalet.

Extinct Hippopotamuses
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, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
