Palaeospheniscus
''Palaeospheniscus'' is an extinct genus of penguins belonging to the subfamily Palaeospheniscinae. These penguins are apparently not closely related to the modern genus ''Spheniscus''. Description The species of ''Palaeospheniscus'' were medium-sized to largish penguins, ranging from ''P. gracilis'' with an estimated maximal length of 55 cm to ''P. wimani'', which reached up to 73 cm. Species This genus contains the following three species: *''Palaeospheniscus patagonicus'' ( type) *''Palaeospheniscus bergi'' *''Palaeospheniscus biloculatus'' The following other species are disputed: *''Palaeospheniscus wimani'' (disputed) *''Palaeospheniscus gracilis'' (disputed) They are all (except ''P. bergi'', which is somewhat enigmatic) known from one or two handful of bones. Most of the specimens were found in Santa Cruz and Chubut Provinces of Patagonia, Argentina. The fossils were recovered from the Patagonian Molasse Formation, and are probably Early Miocene to Late Mio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Palaeospheniscus Bergi
''Palaeospheniscus bergi'' is a species of the extinct penguin genus ''Palaeospheniscus''.''Palaeospheniscus bergi'' at .org It stood about high in life, or somewhat smaller on average than the extant . Etymology The species is named for Carlos Berg, a member of the La Plata Museum of Natural Sciences staff at the time when |
Palaeospheniscus Patagonicus
''Palaeospheniscus patagonicus'' is the type species of the penguin genus ''Palaeospheniscus'', which is known from fossils. It stood about high in life, roughly the size of an African penguin. Description This species is known from several dozen bones, found in Early Miocene strata of the Gaiman Formation. The specimens from known localities were collected near Trelew and Gaiman in Chubut Province, Argentina.''Palaeospheniscus patagonicus'' at .org Currently, there is some debate about whether '' |
Palaeospheniscus Gracilis
''Palaeospheniscus gracilis'' is a species of the extinct penguin genus ''Palaeospheniscus''. It is the smallest species of its genus, with a height of . Average individuals, thus, were about the size of the Galapagos penguin. Description This species was long believed to have first been found in Early Oligocene deposits. However, it seems that the type specimen, a tarsometatarsus, was recovered not from Early Oligocene rocks, but was found on top of them, having been displaced there from a later stratum. The location where the bone was found seems to have been near Cabeza Blanca. At any rate, all later specimens were found in the Early Miocene Gaiman Formation; those that have locality data are from the area around Trelew and Gaiman in Chubut Province, Argentina.''Palaeospheniscus g ...

Palaeospheniscus Wimani
The extinct penguin ''Palaeospheniscus wimani'' is a member of the genus ''Palaeospheniscus'', which belonged to the prehistoric subfamily Palaeospheniscinae. It was the largest member of its genus, being just as large as the Magellanic penguin of today (to which it is quite unrelated). Description A fairly large number of fossil bones has been found, some of which are tentatively assigned to this species. They are from the Early Miocene Gaiman Formation. The specimens from known localities were collected near Trelew and Gaiman in Chubut Province, Argentina.''Palaeospheniscus wimani'' at .org As there is not much notable difference apart from size, ...

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 ...

Spheniscus
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. The genus name ''Spheniscus'' is derived from the Ancient G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Early Oligocene
The Rupelian is, in the geologic timescale, the older of two ages or the lower of two stages of the Oligocene Epoch/Series. It spans the time between . It is preceded by the Priabonian Stage (part of the Eocene) and is followed by the Chattian Stage. Name The stage is named after the small river Rupel in Belgium, a tributary to the Scheldt. The Belgian Rupel Group derives its name from the same source. The name Rupelian was introduced in scientific literature by Belgian geologist André Hubert Dumont in 1850. The separation between the group and the stage was made in the second half of the 20th century, when stratigraphers saw the need to distinguish between lithostratigraphic and chronostratigraphic names. Stratigraphic definition The base of the Rupelian Stage (which is also the base of the Oligocene Series) is at the extinction of the foraminiferan genus ''Hantkenina''. An official GSSP for the base of the Rupelian has been assigned in 1992 (Massignano, Italy). The transi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chile
Chile, officially the Republic of Chile, is a country in the western part of South America. It is the southernmost country in the world, and the closest to Antarctica, occupying a long and narrow strip of land between the Andes to the east and the Pacific Ocean to the west. Chile covers an area of , with a population of 17.5 million as of 2017. It shares land borders with Peru to the north, Bolivia to the north-east, Argentina to the east, and the Drake Passage in the far south. Chile also controls the Pacific islands of Juan Fernández, Isla Salas y Gómez, Desventuradas, and Easter Island in Oceania. It also claims about of Antarctica under the Chilean Antarctic Territory. The country's capital and largest city is Santiago, and its national language is Spanish. Spain conquered and colonized the region in the mid-16th century, replacing Inca rule, but failing to conquer the independent Mapuche who inhabited what is now south-central Chile.
