Spheniscus Mendiculus Juvenile
The banded penguins are penguins that belong to the genus ''Spheniscus''. There are four living species, all with similar banded plumage patterns. They are sometimes also known as "jack-ass penguins" due to their loud locator calls sounding similar to a donkey braying. Common traits include a band of black that runs around their bodies bordering their black dorsal coloring, black beaks with a small vertical white band, distinct spots on their bellies, and a small patch of unfeathered or thinly feathered skin around their eyes and underdeveloped fluff sack that can be either white or pink. All members of this genus lay eggs and raise their young in nests situated in burrows or natural depressions in the earth. Systematics Banded penguins belong to the genus ''Spheniscus'', which was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the African penguin (''Spheniscus demersus'') as the type species.

Middle Miocene
The Middle Miocene is a sub-epoch of the Miocene Epoch made up of two stages: the Langhian and Serravallian stages. The Middle Miocene is preceded by the Early Miocene. The sub-epoch lasted from 15.97 ± 0.05 Ma to 11.608 ± 0.005 Ma (million years ago). During this period, a sharp drop in global temperatures took place. This event is known as the Middle Miocene Climate Transition. For the purpose of establishing European Land Mammal Ages The European Land Mammal Mega Zones (abbreviation: ELMMZ, more commonly known as European land mammal ages or ELMA) are zones in rock layers that have a specific assemblage of fossils (biozones) based on occurrences of fossil assemblages of Europe ... this sub-epoch is equivalent to the Astaracian age.

Humboldt Penguin
The Humboldt penguin (''Spheniscus humboldti'') is a medium-sized penguin. It resides in South America, its range mainly contains most of coastal Peru. Its nearest relatives are the African penguin, the Magellanic penguin and the Galápagos penguin. The Humboldt penguin and the cold water current it swims in both are named after the explorer Alexander von Humboldt. The species is listed as vulnerable by the IUCN with no population recovery plan in place. The current population is composed of 32,000 mature individuals and is going down. It is a migrant species. Humboldt penguins nest on islands and rocky coasts, burrowing holes in guano and sometimes using scrapes or caves. In South America the Humboldt penguin is found only along the Pacific coast, and the range of the Humboldt penguin overlaps that of the Magellanic penguin on the central Chilean coast. It is vagrant in Ecuador and Colombia. The Humboldt penguin has been known to live in mixed species colonies with the Magell ...

Spheniscus Muizoni
''Spheniscus muizoni'' is an extinct species of banded penguins that lived during the early Late Miocene in what is now Peru, South America. The species, the earliest member of the extant genus, was described in 2007 by Ursula B. Göhlich based on fossils found in the fossiliferous Pisco Formation of the Pisco Basin, southwestern Peru. Discovery and naming Fossils of ''Spheniscus muizoni'' were found by French paleontologist Christian de Muizon in sediments belonging to the Pisco Formation at the locality Cerro la Bruja in the middle of the Pisco Basin. The material is owned by the Muséum National d'Histoire Naturelle in Paris.Göhlich, 2007, p.286 The species epithet was chosen in honour of De Muizon, who has greatly contributed to the faunal descriptions of the Pisco Formation and other areas in Peru. Description The holotype material consists of a partial postcranial skeleton, subcomplete left and right coracoid, subcomplete right scapula, a subcomplete left and right ...

Spheniscus Megaramphus
''Spheniscus megaramphus'' (from Greek; ''megas'', 'large', and ''ramphos'', 'beak') is an extinct species of penguin that lived during the Late Miocene (present Peru) South America. It is notable for being the largest known species of banded penguin, along with having a proportionally large beak. The species was described in 2003 by Marcelo Stucchi based on fossils found in the fossiliferous Pisco Formation of the Pisco Basin, southwestern Peru. At about three feet in height, ''Spheniscus megaramphus'' was significantly larger and more robust than any living banded penguin. The beak of ''S. megaramphus'' is also proportionally much larger compared to extant banded penguins; the beak of ''S. megaramphus'' exceeds the length of its cranium, whereas the Humboldt penguin's beak and cranium are roughly equal in length. ''S. megaramphus'' is one of many extinct penguin species found in the Pisco Formation, along with other extinct banded penguins such as '' S. muizoni'' and '' S. urb ...

Zanclean
The Zanclean is the lowest stage or earliest age on the geologic time scale of the Pliocene. It spans the time between 5.332 ± 0.005 Ma (million years ago) and 3.6 ± 0.005 Ma. It is preceded by the Messinian Age of the Miocene Epoch, and followed by the Piacenzian Age. The Zanclean can be correlated with regionally used stages, such as the Opoitian of New Zealand, and the Tabianian or Dacian of Central Europe. It also corresponds to the late Hemphillian to mid-Blancan North American Land Mammal Ages. In California, the Zanclean roughly corresponds to the middle part of the Delmontian stage. Definition The Zanclean Stage was introduced by Giuseppe Seguenza in 1868. It is named after ''Zancle'', the pre-Roman name for the Italian city of Messina on Sicily. The base of the Zanclean (and the Pliocene Series) lies with the top of magnetic chronozone Cr3 (about 100,000 years before the Thvera normal subchronozone C3n.4n). The base is also close to the extinction level of the calc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Late Miocene
The Late Miocene (also known as Upper Miocene) is a sub-epoch of the Miocene epoch (geology), Epoch made up of two faunal stage, stages. The Tortonian and Messinian stages comprise the Late Miocene sub-epoch, which lasted from 11.63 Ma (million years ago) to 5.333 Ma. The evolution of life The gibbons (family Hylobatidae) and orangutans (genus ''Pongo'') are the first groups to split from the line leading to the hominins, including humans, then gorillas (genus ''Gorilla''), and finally, chimpanzees and bonobos (genus ''Pan (genus), Pan''). The splitting date between hominin and chimpanzee lineages is placed by some between 4 to 8 million years ago, that is, during the Late Miocene.

Spheniscus Anglicus
''Spheniscus anglicus'' is an extinct species of banded penguin that lived during the Late Miocene in what is now Chile, South America. The species was described in 2015 by Richard D. Benson based on a fossil found in the Bahia Inglesa Formation in northern Chile. Description The holotype material consists of a fossil penguin skull, without a beak. The species is described as smaller than the emperor penguin or the king penguin, but larger than any other in the genus. Discovery and naming The only known current fossil of ''Spheniscus anglicus'' was recovered from the Bahia Inglesa Formation at an unknown date, and later sold at the 2001 Tucson Gem & Mineral Show to Mark Rasmussen, who later donated it to the Science Museum of Minnesota Science Museum of Minnesota is an American museum focused on topics in technology, natural history, physical science, and mathematics education.

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