Maltese Hippopotamus
''Hippopotamus melitensis'' is an extinct hippopotamus from Malta. It arrived after the Messinian salinity crisisHunt, Christopher O., Schembri, Patrick J.Quaternary Environments and Biogeography of the Maltese Islands, page 31, access in 13/03/2016 and lived during the Pleistocene. The absence of predators, and limited food supplies led to the dwarfing of the hippos. The majority of findings of this species are from Għar Dalam, a cave on Malta famous for its Pleistocene fossil deposits.

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 ...

Charles Immanuel Forsyth Major
Charles Immanuel Forsyth Major (15 August 1843, Glasgow – 25 March 1923, Munich) was a Scottish-born, Swiss physician, zoologist and vertebrate palaeontologist. Major was born in Glasgow and studied at Basel and Zurich Universities in Switzerland and later Göttingen in Germany. He graduated in medicine at Basel in 1868 and became a physician in Florence, Italy. Like many early naturalists he spent his free time studying fossil mammals. His first publication was on fossil primates in 1872. The Italian government supported him in 1877 and he collected fossils from Calabria, Corsica, Sardinia, and Sicily. In 1886, he stopped practising as a physician and began to study fossils in the Greek Archipelago with his collections going to the College Galliard at Lausanne and to the British Museum (Natural History). In the British Museum collections he took a keen interest in material from Madagascar. He studied the lemur fauna, both extant and extinct, discovered the new family Megaladap ...

Hippopotamidae
Hippopotamidae is a family of stout, naked-skinned, and semiaquatic artiodactyl mammals, possessing three-chambered stomachs and walking on four toes on each foot. While they resemble pigs physiologically, their closest living relatives are the cetaceans. They are formally referred to as hippopotamids. There are two living species of hippopotamid in two genera; the pygmy hippo, ''Choeropsis liberiensis'' of the forests of west Africa, and the common hippo, ''Hippopotamus amphibius''. The term ''hippopotamus'' can also be applied to hippopotamids in general, although it is most frequently used for the common hippo and its respective genus. Characteristics Hippopotamids are large mammals, with short, stumpy legs, and barrel-shaped bodies. They have large heads, with broad mouths, and nostrils placed at the top of their snouts. Like pigs, they have four toes, but unlike pigs, all of the toes are used in walking. Hippopotamids are unguligrade, although, unlike most other such a ...

Malta
Malta ( , , ), officially the Republic of Malta ( mt, Repubblika ta' Malta ), is an island country in the Mediterranean Sea. It consists of an archipelago, between Italy and Libya, and is often considered a part of Southern Europe. It lies south of Sicily (Italy), east of Tunisia, and north of Libya. The official languages are Maltese and English, and 66% of the current Maltese population is at least conversational in the Italian language. Malta has been inhabited since approximately 5900 BC. Its location in the centre of the Mediterranean has historically given it great strategic importance as a naval base, with a succession of powers having contested and ruled the islands, including the Phoenicians and Carthaginians, Romans, Greeks, Arabs, Normans, Aragonese, Knights of St. John, French, and British, amongst others. With a population of about 516,000 over an area of , Malta is the world's tenth-smallest country in area and fourth most densely populated sovereign cou ...

Messinian Salinity Crisis
The Messinian salinity crisis (MSC), also referred to as the Messinian event, and in its latest stage as the Lago Mare event, was a geological event during which the Mediterranean Sea went into a cycle of partial or nearly complete desiccation (drying-up) throughout the latter part of the Messinian age of the Miocene epoch, from 5.96 to 5.33 Ma (million years ago). It ended with the Zanclean flood, when the Atlantic reclaimed the basin. Sediment samples from below the deep seafloor of the Mediterranean Sea, which include evaporite minerals, soils, and fossil plants, show that the precursor of the Strait of Gibraltar closed tight about 5.96 million years ago, sealing the Mediterranean off from the Atlantic. This resulted in a period of partial desiccation of the Mediterranean Sea, the first of several such periods during the late Miocene. After the strait closed for the last time around 5.6 Ma, the region's generally dry climate at the time dried the Mediterranean basin out near ...

Insular Dwarfism
Insular dwarfism, a form of phyletic dwarfism, is the process and condition of large animals evolving or having a reduced body size when their population's range is limited to a small environment, primarily islands. This natural process is distinct from the intentional creation of dwarf breeds, called dwarfing. This process has occurred many times throughout evolutionary history, with examples including dinosaurs, like '' Europasaurus'' and ''Magyarosaurus dacus'', and modern animals such as elephants and their relatives. This process, and other "island genetics" artifacts, can occur not only on islands, but also in other situations where an ecosystem is isolated from external resources and breeding. This can include caves, desert oases, isolated valleys and isolated mountains ("sky islands"). Insular dwarfism is one aspect of the more general "island effect" or "Foster's rule", which posits that when mainland animals colonize islands, small species tend to evolve larger bodies ...

Għar Dalam
Għar Dalam ("Cave of Dalam" (a fifteenth century family name), ) is a 144 metre long phreatic tube and cave, or cul-de-sac, located in the outskirts of Birżebbuġa, Malta. The cave contains the bone remains of animals that were stranded and subsequently became extinct in Malta at the end of the Last Glacial Maximum. It has lent its name to the Għar Dalam phase in Maltese prehistory, and is viewed as one of Malta's most important national monuments. Pottery similar to that found in Stentinello was found at Għar Dalam, but lacking details such as stamp decorations. Dwarf elephant, hippopotamus, giant swan, deer and bear bone deposits found there are of different ages; the hippopotamuses became extinct about 10,000 years ago, whilst the deer species became extinct much later, about 4000 years ago during the Chalcolithic. It is also here that the earliest evidence of human settlement on Malta, some 7,400 years ago, was discovered. Recent history The cave was first investig ...

Cretan Dwarf Hippopotamus
''Hippopotamus creutzburgi'', the Cretan dwarf hippopotamus, is an extinct species of hippopotamus from the island of Crete. ''Hippopopotamus'' colonized Crete probably 800,000 years ago and lived there during the Middle Pleistocene. Bones of ''H. creutzburgi'' were found by Dorothea Bate on the Katharo plateau, in eastern Crete, in the 1900s.Bate, D.M.A., (1905): I. Four and a half months in Crete in search of Pleistocene mammalian remains. Geol. Mag. 2: 13-204. A similar species, the Cyprus dwarf hippopotamus (''Phanourios minor'') lived on the island of Cyprus until the Holocene. It was at least 20% smaller than either subspecies of Cretan hippo.

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] |
