Palaelodus
''Palaelodus'' is an extinct genus of bird of the Palaelodidae family, distantly related to flamingos. They were slender birds with long, thin legs and a long neck resembling their modern relatives, but likely lived very different livestyles. They had straight, conical beaks not suited for filter feeding and legs showing some similarities to grebes. Their precise lifestyle is disputed, with researchers in the past suggesting they may have been divers, while more recent research suggests they may have used their stiff toes as paddles for swimming while feeding on insect larvae and snails. This behavior may have been key in later phoenicopteriforms developing filterfeeding bills. The genus includes between five to eight species and is found across Europe, Australia, New Zealand, Asia and possibly South America. However some argue that most of the taxa named from Europe simply represent differently sized individuals of one single species. ''Palaelodus'' was most abundant during the ...

Megapaloelodus
''Megapaloelodus'' is an extinct genus of stem flamingo of the family Palaelodidae. ''Megapaloelodus'' is primarily known from Miocene America, from South Dakota and Oregon in the north to Argentina in the south, but the species ''Megapaloelodus goliath'' was found in Europe. Additionally, one unnamed species was discovered in Miocene sediments from Namibia. Due to a lack of skull material, little can be said about the ecology of ''Megapaloelodus''. Species of this genus are typically larger than those of ''Palaelodus'' and appear to have inhabited similar brackish lake environments. Additionally, they may have been capable of "locking" their legs in a standing position. History and naming ''Megapaloelodus'' was named by American Alden H. Miller in 1944 on the basis of a fossil femur and tarsometatarsus collected from the lower Miocene Rosebud Formation of South Dakota. Recognizing similarities to fossils of ''Palaelodus'', Miller described the material as a new genus of phoeni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palaelodidae
Palaelodidae is a family of extinct birds in the group Phoenicopteriformes, which today is represented only by the flamingos. They have been described as "swimming flamingos." They can be considered evolutionarily, and ecologically, intermediate between flamingos and grebes. Three genera are recognised: * †'' Adelalopus'' (Mayr & Smith 2002), called the "stout-legged flamingos" (Borgloon Early Oligocene of Hoogbutsel, Belgium) ** †'' Adelalopus hoogbutseliensis'' (Mayr and Smith 2002) * †''Palaelodus'' (Milne-Edwards 1863) Pliogrus.html"_;"title="'Pliogrus">'Pliogrus''_(Lambrecht_1933)(Middle_Oligocene_–?_Middle_Pleistocene) **_†''Palaelodus_ambiguus.html" ;"title="Pliogrus">'Pliogrus'' (Lambrecht 1933)">Pliogrus.html" ;"title="'Pliogrus">'Pliogrus'' (Lambrecht 1933)(Middle Oligocene –?

Saint Bathans Fauna
The St Bathans fauna is found in the lower Bannockburn Formation of the Manuherikia Group of Central Otago, in the South Island of New Zealand. It comprises a suite of fossilised prehistoric animals from the late Early Miocene (Altonian) period, with an age range of 19–16 million years ago. The layer in which the fossils are found derives from littoral zone sediments deposited in a shallow, freshwater lake, with an area of 5600 km2 from present day Central Otago to Bannockburn and the Nevis Valley in the west; to Naseby in the east; and from the Waitaki Valley in the north to Ranfurly in the south. The lake was bordered by an extensive floodplain containing herbaceous and grassy wetland habitats with peat-forming swamp–woodland. At that time the climate was warm with a distinctly subtropical Australian climate and the surrounding vegetation was characterised by casuarinas, eucalypts and palms as well as podocarps, araucarias and southern beeches.

Tibiotarsi Of Extinct Birds
The tibiotarsus is the large bone between the femur and the tarsometatarsus in the leg of a bird. It is the fusion of the proximal part of the tarsus with the tibia. A similar structure also occurred in the Mesozoic Heterodontosauridae. These small ornithischian dinosaurs were unrelated to birds and the similarity of their foot bones is best explained by convergent evolution. See also *Bird anatomy References * Proctor, Nobel S.

Flamingos
Flamingos or flamingoes are a type of wading bird in the family Phoenicopteridae, which is the only extant family in the order Phoenicopteriformes. There are four flamingo species distributed throughout the Americas (including the Caribbean), and two species native to Afro-Eurasia. A group of flamingoes is called a "flamboyance." Etymology The name ''flamingo'' comes from Portuguese or Spanish ("flame-colored"), which in turn comes from Provençal – a combination of ("flame") and a Germanic-like suffix ''-ing''. The word may also have been influenced by the Spanish ethnonym ("Fleming" or "Flemish"). The name of the genus, ''Phoenicopterus'', is from the Greek , ); other genera names include ''Phoeniconaias,'' which means "crimson/red water nymph (or naiad)", and ''Phoenicoparrus,'' which means "crimson/red bird (though, an unknown bird of omen)". Taxonomy and systematics The family Phoenicopteridae was introduced by the French zoologist Charles Lucien Bonapar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Bannockburn, New Zealand
Bannockburn is a small historic gold mining town located outside of Cromwell in Central Otago, New Zealand. The area was first made known as a rich alluvial gold field and was mined extensively in the 1860s. Its uniquely warm, dry climate earned it the name 'The heart of the desert', as climatic conditions and human activity have combined to strip the area of most of the original native vegetation leaving rocks, sands and soils exposed. Today, these climate conditions make Bannockburn the home of many vineyards and stonefruit orchards. History The plans for the settlement began in 1862, as a result of miners being forced upstream from rising water levels in the Clutha and Kawarau Rivers. Though the area was settled around this period, the population was not stationary. As miners followed gold up the creeks, the settlements tended to follow, and by 1868 the original settlement had been strung out along what is now the Bannockburn-Nevis road. As miners swept over the area, f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Eyre Basin
The Lake Eyre basin ( ) is a drainage basin that covers just under one-sixth of all Australia. It is the largest endorheic basin in Australia and amongst the largest in the world, covering about , including much of inland Queensland, large portions of South Australia and the Northern Territory, and a part of western New South Wales. The basin is also one of the largest, least-developed arid zone basins with a high degree of variability anywhere. It supports only about 60,000 people and has no major irrigation, diversions or flood-plain developments. Low density grazing that sustains a large amount of wildlife is the major land use, occupying 82% of the total land within the basin. The Lake Eyre basin of precipitation (rain water) to a great extent geographically overlaps the Great Artesian Basin underneath. The basin began as a sinking landmass mostly covered by forest and contained many more lakes than now. The climate has changed from wet to arid over the last 60 million years ...

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mongolia
Mongolia; Mongolian script: , , ; lit. "Mongol Nation" or "State of Mongolia" () is a landlocked country in East Asia, bordered by Russia to the north and China to the south. It covers an area of , with a population of just 3.3 million, making it the world's most sparsely populated sovereign nation. Mongolia is the world's largest landlocked country that does not border a closed sea, and much of its area is covered by grassy steppe, with mountains to the north and west and the Gobi Desert to the south. Ulaanbaatar, the capital and largest city, is home to roughly half of the country's population. The territory of modern-day Mongolia has been ruled by various nomadic empires, including the Xiongnu, the Xianbei, the Rouran, the First Turkic Khaganate, and others. In 1206, Genghis Khan founded the Mongol Empire, which became the largest contiguous land empire in history. His grandson Kublai Khan conquered China proper and established the Yuan dynasty.

Pierce Brodkorb
William Pierce Brodkorb (September 29, 1908, Chicago – July 18, 1992, Gainesville, Florida) was an American ornithologist and paleontologist. Interested in birds since childhood, he was taught to prepare birds at the age of 16. Later, he received the opportunity to work as a staff technician in the Ornithology Division of the Field Museum. He entered the University of Michigan in 1933 and obtained his PhD degree in 1936. Subsequently, he became an assistant curator of birds at the Museum of Zoology in Michigan until 1946. In 1946, he accepted a professorate in the Department of Zoology at the University of Florida in Gainesville, a position he held until his retirement in 1989. His doctoral students include Glen E. Woolfenden. From the 1950s, Brodkorb built up a huge collection of bird fossils from the Miocene, the Pliocene, and the Pleistocene of Florida, which included 12,500 skeletons from 129 families, and is on display at the Florida Museum of Natural History, part ...
