Perimecturus Fraiponti
''Gorgonophontes'' is an extinct genus of mantis shrimp that lived during the late Carboniferous period in what is now the United States and Belgium. It contains two named species. The type species, ''G. peleron'', was described in 1984 by Frederick Schram based on 100 specimens found in Nebraska and Iowa. A second species, ''G. fraiponti'', was first named from multiple specimens found near Liège in 1922 and later reassigned to the genus. A small crustacean with a total length of around , this animal had a subrectangular carapace, a telson that narrows into a spike at the end, and four pairs of maxillipeds enlarged into raptorial appendages, the frontmost pair being larger than the others. It has been suggested to be a benthopelagic predator, using these appendages to capture prey, possibly from above, while swimming over the seabed. Discovery and naming The first fossils of ''Gorgonophontes'' to be discovered were found decades before the genus was named. In 1922, Victor van ...

Victor Van Straelen
Victor van Straelen (14 June 1889 – 29 February 1964) was a Belgian conservationist, palaeontologist and carcinologist. Van Straelen was born in Antwerp on 14 June 1889, and worked chiefly as a palaeontologist until his retirement in 1954. He was director of the Royal Belgian Institute of Natural Sciences from 1925 to 1954. In 1926, he instigated the world's first gorilla sanctuary in what became the ' (now Virunga National Park). In 1933, he was appointed head of the ', and in 1948, he was on the executive committee at the foundation of the organisation which would become the International Union for Conservation of Nature (IUCN). He was the first president of the Charles Darwin Foundation from its foundation in 1959 until his death in 1964. He was awarded a silver Darwin-Wallace Medal by the Linnean Society of London The Linnean Society of London is a learned society dedicated to the study and dissemination of information concerning natural history, evolution, and ta ...

Gorgons
A Gorgon ( /ˈɡɔːrɡən/; plural: Gorgons, Ancient Greek: Γοργών/Γοργώ ''Gorgṓn/Gorgṓ'') is a creature in Greek mythology. Gorgons occur in the earliest examples of Greek literature. While descriptions of Gorgons vary, the term most commonly refers to three sisters who are described as having hair made of living, venomous snakes and horrifying visages that turned those who beheld them to stone. Traditionally, two of the Gorgons, Stheno and Euryale, were immortal, but their sister Medusa was not and was slain by the demigod and hero Perseus. Etymology The name derives from the Ancient Greek word (), which means 'grim or dreadful', and appears to come from the same root as the Sanskrit word (), which means a guttural sound, similar to the growling of a beast, thus possibly originating as an onomatopoeia. Depictions Gorgons were a popular image in Greek mythology, appearing in the earliest of written records of Ancient Greek religious beliefs such as those ...

Papillion, Nebraska
Papillion is a city in Sarpy County in the state of Nebraska, United States. Designated as the county seat, it developed as an 1870s railroad town and suburb of Omaha. The city is part of the larger five-county metro area of Omaha. Papillion's population was 24,159 at the 2020 census. Its growth since the late 20th century has reflected Omaha's. Overview The city was named after the creek of the same name which flows through its center; this had been named by early French explorers, as France had claimed this territory through the eighteenth century. The name Papillion is derived from the French term (''papillon'') for butterfly. According to local tradition, the early French explorers named the creek as ''Papillon'' because they saw so many butterflies along its grassy banks. The spelling was changed through a transliteration of the French word. Papillion was platted in 1870 when the railroad was extended to that point. Papillion (sometimes referred to as "Papio" by its resid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessaril ...

Oread Formation
The Oread Limestone is a geologic unit of formation rank within the Shawnee Group throughout much of its extent. It is exposed in Kansas, Nebraska, Missouri, Oklahoma, and Iowa. The type locality is Mount Oread within Lawrence, Kansas. It preserves fossils of the Carboniferous period. Although it has significant shale members, its limestone members are resistant and form escarpments and ridges. Limestone from the unit is a historic building material in Kansas, particularly in the early buildings of the University of Kansas; standing examples include Spooner Hall and Dyche Hall.

Pennsylvanian (geology)
The Pennsylvanian ( , also known as Upper Carboniferous or Late Carboniferous) is, in the ICS geologic timescale, the younger of two subperiods (or upper of two subsystems) of the Carboniferous Period. It lasted from roughly . As with most other geochronologic units, the rock beds that define the Pennsylvanian are well identified, but the exact date of the start and end are uncertain by a few hundred thousand years. The Pennsylvanian is named after the U.S. state of Pennsylvania, where the coal-productive beds of this age are widespread. The division between Pennsylvanian and Mississippian comes from North American stratigraphy. In North America, where the early Carboniferous beds are primarily marine limestones, the Pennsylvanian was in the past treated as a full-fledged geologic period between the Mississippian and the Permian. In parts of Europe, the Mississippian and Pennsylvanian are one more-or-less continuous sequence of lowland continental deposits and are grouped ...

Monotypic Taxon
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. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.' ...

Junior Synonyms
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, 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 forms of the species now referred to as ''Araschnia leva ...
