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, ...

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.

Chubut Province
Chubut ( es, Provincia del Chubut, ; cy, Talaith Chubut) is a province in southern Argentina, situated between the 42nd parallel south (the border with Río Negro Province), the 46th parallel south (bordering Santa Cruz Province), the Andes range to the west, and the Atlantic ocean to the east. The province's name derives from the Tehuelche word , meaning "transparent," their description of the Chubut River. The largest city is Comodoro Rivadavia in the south of the province; it has 180,000 inhabitants. The administrative capital is Rawson (40,000). Other important cities are Puerto Madryn, Trelew, Esquel and Sarmiento. Gaiman is a cultural and demographic centre of the region known as ''"Y Wladfa"'' in which Welsh-Argentines are concentrated. Of the 25,000 Welsh speakers in Argentina, 5,000 live in the Chubut region, particularly in the early Welsh settlements of Gaiman, Trelew and Trevelin.

Fossils Of Argentina
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolute ...

Neogene Argentina
The Neogene ( ), informally Upper Tertiary or Late Tertiary, is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period million years ago ( Mya) to the beginning of the present Quaternary Period Mya. The Neogene is sub-divided into two epochs, the earlier Miocene and the later Pliocene. Some geologists assert that the Neogene cannot be clearly delineated from the modern geological period, the Quaternary. The term "Neogene" was coined in 1853 by the Austrian palaeontologist Moritz Hörnes (1815–1868). During this period, mammals and birds continued to evolve into modern forms, while other groups of life remained relatively unchanged. The first humans (''Homo habilis'') appeared in Africa near the end of the period. Some continental movements took place, the most significant event being the connection of North and South America at the Isthmus of Panama, late in the Pliocene. This cut off the warm ocean currents from the Pacific to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Extinct Penguins
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, mam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Binomen
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Wiman
Carl Johan Josef Ernst Wiman (March 10, 1867 – June 15, 1944) was a Swedish palaeontologist, the first professor of palaeontology and historical geology at Uppsala University, and the father of Swedish vertebrate palaeontology. Wiman was instrumental in the construction of the Palaeontological Museum of Uppsala University (now part of the Museum of Evolution), which contains the largest collection of Chinese fossil vertebrate material outside China. He is responsible for naming the genera ''Helopus'' (renamed ''Euhelopus'' because ''Helopus'' was already in use) and ''Tanius'', and the species '' Pentaceratops fenestratus'' and '' Parasaurolophus tubicen''. He was also the first to suggest that the hollow cranial crests of lambeosaurine duckbill dinosaurs could be used as a horn-like noisemaker. Early life Family Wiman was born on 10 March 1867 in the recently inaugurated Märsta railway station, located on Husby-Odensala, Stockholm. Wiman's father was a Swedis ...

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 '' |
Synonym (zoology)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In nomenclature, botanical nomenclature, a synonym is a Binomial nomenclature, scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Carl Linnaeus, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal form ...
