Palaeeudyptes
''Palaeeudyptes'' is an extinct genus of large penguins, currently containing four accepted species. They were probably larger than almost all living penguins, with the smaller species being about the size of an emperor penguin, and the largest species, ''Palaeeudyptes klekowskii'', having stood up to tall and weighed up to . Known species Of the four species, two (''P. gunnari'' and ''P. klekowskii'') are known from numerous remains found in Middle or Late Eocene strata (34 to 50 MYA) of the La Meseta Formation on Seymour Island, Antarctica. ''P. antarcticus'', the first fossil penguin described, is only really known from a single incomplete tarsometatarsus found in the Late Oligocene Otekaike Limestone (23 to 28, possibly up to 34 MYA) at Kakanui, New Zealand, but numerous other bones have been tentatively assigned to the species. The other described New Zealand species, ''P. marplesi'', is known from parts of a skeleton, mainly leg bones, from the Middle or Late Eocene Bu ...

Palaeeudyptes Antarcticus
''Palaeeudyptes antarcticus'', also referred to as the narrow-flippered penguin, is the type species of the extinct penguin genus ''Palaeeudyptes''. It was a huge species, albeit probably with a large size variation. Although the size range can only be loosely estimated, the birds seem to have stood between high in life (''i.e.'' somewhat larger than an emperor penguin), placing this species and its congener '' Palaeeudyptes marplesi'' among the largest penguin species known. It was the last known ''Palaeeudyptes'' species, and although the exact time when it lived is not precisely determined, it may have evolved from ''P. marplesi'', or they might even have been a single species which slightly decreased in size over time. ''P. antarcticus'' was the first fossil penguin to become known to science. It was described from a single, slightly damaged, tarsometatarsus ( BM A.1084) found in the Late Oligocene Otekaike Limestone (23-28, possibly up to 34 MYA) at Kakanui, New Zealand. ...

Palaeeudyptes Klekowskii
''Palaeeudyptes klekowskii'', also known as the colossus penguin, was a species of the extinct penguin genus ''Palaeeudyptes''. It was until recently thought to have been approximately the size of its congener ''Palaeeudyptes antarcticus'', which would mean it was somewhat larger than the modern emperor penguin, but a new study shows it was in fact almost twice as tall. Its maximum height is estimated to be up to and maximum body mass up to . Knowledge of it comes from an extensive collection of fossil bones from the Late Eocene (34-37 MYA) of the La Meseta Formation on Seymour Island, Antarctica. ''P. klekowskii'' was at first not recognized as a distinct species, and despite the coexistence of two so closely related species of similar size as ''Palaeeudyptes gunnari ''Palaeeudyptes gunnari'' is an extinct species of the extinct penguin genus ''Palaeeudyptes''. It was a bit smaller than its congener '' Palaeeudyptes antarcticus'' of New Zealand, standing between 110 and 125 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palaeeudyptes Marplesi
Marples' penguin (''Palaeeudyptes marplesi'') was a large species of the extinct penguin genus ''Palaeeudyptes''. It stood between high in life, larger than the present emperor penguin. The precise relationship between this species and the slightly smaller narrow-flippered penguin (''Palaeeudyptes antarcticus'') from somewhat younger rocks is not resolved; possibly, ''P. marplesi'' is a synonym or subspecies of ''P. antarcticus''. This species is known from a partial skeleton, mainly leg bones (Otago Museum C.50.25 to C.50.45), recovered from Middle or Late Eocene Burnside Mudstone rocks (34-40 MYA) at Burnside, Dunedin, in New Zealand. Many other bones are often assigned to this species. However, as most of them are only roughly dated and intermediate in size between this species and ''P. antarcticus'', they should not be referred to either taxon pending a comprehensive review of the New Zealand material of ''Palaeeudyptes'' (which will probably result in recognizing that ' ...

Palaeeudyptes Gunnari
''Palaeeudyptes gunnari'' is an extinct species of the extinct penguin genus ''Palaeeudyptes''. It was a bit smaller than its congener ''Palaeeudyptes antarcticus'' of New Zealand, standing between 110 and 125 cm high, approximately the size of the emperor penguin. It is known from dozens of fossil bones from Middle or Late Eocene strata (34-50 MYA) of the La Meseta Formation on Seymour Island, Antarctica. Initially, it was described as a separate genus, ''Eosphaeniscus''. However, this was based on a single weathered and broken tarsometatarsus The tarsometatarsus is a bone that is only found in the lower leg of birds and some non-avian dinosaurs. It is formed from the fusion of several bones found in other types of animals, and homologous to the mammalian tarsus (ankle bones) and meta .... Better material recovered later showed that the species belongs into the present genus. '' Wimanornis'' is probably a synonym of this species (Jadwiszcak, 2006). References * * My ...

La Meseta Formation
The La Meseta Formation is a sedimentary sequence deposited during the Eocene. The formation is found on Seymour Island, Antarctica. Description La Meseta Formation lies unconformably on the Cretaceous Lopez de Bertodano Formation. It is an approximately thick sequence of poorly consolidated sandstones and siltstones. The depositional environment was probably coastal, deltaic or estuarine in character. The top of the sequence is an erosional unconformity to Pleistocene glacial gravels. La Meseta Formation is one of the sequences that make up the fill of the Late Jurassic to Paleogene James Ross Basin. Fossil content La Meseta Formation is extremely rich in fossils. Among mammals, the meridiungulata ''Antarctodon'' and ''Trigonostylops'' have been found in the formation.''Antarctodon'' at Fossilworks.org ...

Penguin
Penguins (order (biology), order List of Sphenisciformes by population, Sphenisciformes , family (biology), family Spheniscidae ) are a group of Water bird, aquatic flightless birds. They live almost exclusively in the Southern Hemisphere: only one species, the Galápagos penguin, is found north of the Equator. Highly adapted for life in the water, penguins have Countershading, countershaded dark and white plumage and flippers for swimming. Most penguins feed on krill, fish, squid and other forms of sea life which they catch with their bills and swallow it whole while swimming. A penguin has a spiny tongue and powerful jaws to grip slippery prey. They spend roughly half of their lives on land and the other half in the sea. The largest living species is the emperor penguin (''Aptenodytes forsteri''): on average, adults are about tall and weigh . The smallest penguin species is the Little penguin, little blue penguin (''Eudyptula minor''), also known as the fairy penguin, whic ...

Seymour Island
Seymour Island or Marambio Island, is an island in the chain of 16 major islands around the tip of the Graham Land on the Antarctic Peninsula. Graham Land is the closest part of Antarctica to South America. It lies within the section of the island chain that resides off the west side of the peninsula's northernmost tip. Within that section, it is separated from Snow Hill Island by Picnic Passage, and sits just east of the larger key, James Ross Island, and its smaller, neighboring island, Vega Island. Seymour Island is sometimes called Marambio Island or Seymour-Marambio Island, taking its resident Argentine base as its namesake (see section, Base Antárctica Marambio, below). Historic site A wooden plaque and rock cairn stand at Penguins Bay, on the southern coast of Seymour Island. The plaque was placed on 10 November 1903 by the crew of the Argentinian Corvette ''Uruguay'' on a mission to rescue the members of the Swedish expedition led by Otto Nordenskiöld. The inscript ...

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

Thomas Henry Huxley
Thomas Henry Huxley (4 May 1825 – 29 June 1895) was an English biologist and anthropologist specialising in comparative anatomy. He has become known as "Darwin's Bulldog" for his advocacy of Charles Darwin's theory of evolution. The stories regarding Huxley's famous 1860 Oxford evolution debate with Samuel Wilberforce were a key moment in the wider acceptance of evolution and in his own career, although some historians think that the surviving story of the debate is a later fabrication. Huxley had been planning to leave Oxford on the previous day, but, after an encounter with Robert Chambers, the author of '' Vestiges'', he changed his mind and decided to join the debate. Wilberforce was coached by Richard Owen, against whom Huxley also debated about whether humans were closely related to apes. Huxley was slow to accept some of Darwin's ideas, such as gradualism, and was undecided about natural selection, but despite this he was wholehearted in his public support of Darw ...
