Spheniscus Mendiculus Galápagos Ecuador DSC00320 Ed Ad
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 in 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. The genus name ''Spheniscus'' is derived from the Anci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Middle Miocene
The Middle Miocene is a sub-epoch of the Miocene epoch (geology), epoch made up of two Stage (stratigraphy), 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 (million years ago) to 11.608 ± 0.005 Ma. During this period, a sharp drop in global temperatures took place. This event is known as the Middle Miocene disruption, Middle Miocene Climatic Transition. For the purpose of establishing European land mammal ages, this sub-epoch is equivalent to the Astaracian age.

Spheniscus Mendiculus
The Galápagos penguin (''Spheniscus mendiculus'') is a penguin endemic to the Galápagos Islands of Ecuador. It is the only penguin found north of the equator. Most inhabit Fernandina Island and the west coast of Isabela Island. The cool waters of the Humboldt and Cromwell Currents allow it to survive despite the tropical latitude. The Galápagos penguin is one of the banded penguins, the other species of which live mostly on the coasts of Africa and mainland South America. Due to their warm environment, Galápagos penguins have developed techniques to stay cool. The feathers on their back, flippers, and head are black, and they have a white belly and a stripe looping from their eyes down to their neck and chin. Each penguin keeps only one mate, and breeds year-round. Because there is no soft areas to nest, their nests are typically in caves and crevices which also provide protection against predators and the harsh environment. The Galápagos penguin has a lifespan of 20 ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Inguza
''Inguza predemersus'' is an extinct species of penguin. It was formerly placed in the genus '' Spheniscus'' and presumed to be a close relative of the African penguin, but after its well-distinct tarsometatarsus was found, it was moved into its present monotypic genus. The known fossils specimens were found in Late Pliocene rocks in a quarry at Langebaanweg, South Africa, from about 5 million years ago. What is known from molecular data is that the time at which the present species lived is not too distant from the arrival of the ancestors of the African penguin on the Atlantic coasts of southern Africa. On the other hand, it may be closer to ''Pygoscelis''. This would mean that its ancestors diverged from those of the extant ''Pygoscelis'' most likely at an indeterminate point of time during the Oligocene The Oligocene ( ) is a geologic epoch (geology), epoch of the Paleogene Geologic time scale, Period that extends from about 33.9 million to 23 million years before the pre ...

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical syste ...

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. Taxonomy 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 ...

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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spheniscus Chilensis
''Spheniscus chilensis'' is an extinct species of penguin that lived during the Late Pliocene in Chile. The first fossil record of the penguin was discovered on the coast of Antofagasta in 1980, when coastal erosion exposed the first fossilized bone. Discovery and naming ''Spheniscus chilensis'' was discovered in 1980 at the site Cuenca del Tiburón near Antofagasta, Chile, which is part of the Late Pliocene Caleta Herradura Formation. This is the only locality from which it is known to occur. The fossil remains of ''S. chilensis'' consisted of dozens of disarticulated bones from different individuals that had eroded from a nearby rock formation. The specific name "Chilensis" references Chile, the country where it was discovered. See "Spheniscus" for the etymology of the generic name. The name ''Diomedea chilensis'' Molina was published in 1782 in his ''Saggio sulla storia naturale del Chili'' (pp. 238--239). This is an available scientific name which has been construed as a s ...

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 ''Homo'' The gibbons (family Hylobatidae) and orangutans (genus ''Pongo'') were 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 and 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 The Science Museum of Minnesota is a museum in Saint Paul, Minnesota, Saint Paul, Minnesota, focused on topics in technology, natural history, physical science, and mathematics education.
