Kawichthys
''Kawichthys'' was an extinct genus of symmoriiform cartilaginous fish from Upper Pennsylvanian (Late Virgilian stage) deposits of Kansas, United States. ''Kawichthys'' is known from two well preserved three-dimensional neurocrania: the holotype KUVP 152144 is associated with some disturbed and broken postcranial elements, but the braincase is partially crushed, and the paratype KUVP 56340. It was collected from the Douglas Group, between the Haskell Limestone and the lower beds of the overlying Robbins Shale, previously classified as members of the Lawrence Formation or Stranger Formation, but now recognized as members of the extension of the Cass Limestone classification into Kansas. It was first named by Alan Pradel, Paul Tafforeau, John G. Maisey and Philippe Janvier in 2011 and the type species In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically ass ...

Pennsylvanian (geology)
The Pennsylvanian ( , also known as Upper Carboniferous or Late Carboniferous) is, in the International Commission on Stratigraphy, ICS geologic timescale, the younger of two period (geology), subperiods (or upper of two system (stratigraphy), subsystems) of the Carboniferous Period. It lasted from roughly . As with most other geochronology, geochronologic units, the stratum, 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 (geology), 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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paratype
In zoology and botany, a paratype is a specimen of an organism that helps define what the scientific name of a species and other taxon actually represents, but it is not the holotype (and in botany is also neither an isotype nor a syntype). Often there is more than one paratype. Paratypes are usually held in museum research collections. The exact meaning of the term ''paratype'' when it is used in zoology is not the same as the meaning when it is used in botany. In both cases however, this term is used in conjunction with ''holotype''. Zoology In zoological nomenclature, a paratype is officially defined as "Each specimen of a type series other than the holotype.", ''International Code of Zoological Nomenclature'' In turn, this definition relies on the definition of a "type series". A type series is the material (specimens of organisms) that was cited in the original publication of the new species or subspecies, and was not excluded from being type material by the author (th ...

Carboniferous Sharks
The Carboniferous ( ) is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period million years ago ( Mya), to the beginning of the Permian Period, million years ago. The name ''Carboniferous'' means "coal-bearing", from the Latin '' carbō'' ("coal") and '' ferō'' ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern 'system' names, it was coined by geologists William Conybeare and William Phillips in 1822, based on a study of the British rock succession. The Carboniferous is often treated in North America as two geological periods, the earlier Mississippian and the later Pennsylvanian. Terrestrial animal life was well established by the Carboniferous Period. Tetrapods (four limbed vertebrates), which had originated from lobe-finned fish during the preceding Devonian, became pentadactylous in and diversified during the Carboniferous, including early amphibian lineages ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Haskell Limestone
Haskell limestone is a geological unit name originating in Kansas and used in adjoining states. The unit was named in 1931 by R.C. Moore for the then Haskell Indian Nations University, Haskell Institute in the southeast of Lawrence, Kansas. The name has been applied to various beds within this range, and assigned as a member variously to the Lawrence Formation, Cass Formation, and Stranger Formation, and significant legacy literature exists for each classification. These three formations now comprise the Douglas Group. In 2002, within the effort to improve the correlation of Kasimovian, Missourian stage geology between the states of Missouri and Kansas, as well as Nebraska and Iowa, the Haskell was assigned in Kansas to the Cass Formation as its lowest member (on the basis of Principle of faunal succession, distinct changes in fossil species). Distribution and outcrop The Haskell Limestone is recognized in deep hydrocarbon well logs throughout most of the state of Kansas; the " ...

University Of Kansas Natural History Museum
The University of Kansas Natural History Museum is part of the University of Kansas Biodiversity Institute, a KU designated research center dedicated to the study of the life of the planet. The museum's galleries are in Dyche Hall on the university's main campus in Lawrence, Kansas. The galleries are open from 9 a.m. to 5 p.m. Tuesday through Saturday and noon to 4 p.m. on Sundays. Dyche Hall has been listed on the National Register of Historic Places since July 14, 1974; it was listed for its connection with Lewis Lindsay Dyche and for its distinctive Romanesque style of architecture. The exterior is constructed of local Oread Limestone, while the window facings, columns, arches, and grotesques are carved from Cottonwood Limestone. Dyche Hall is also the site of one of only three Victory Eagle statues in Kansas, once used as markers on the Victory Highway. Among its more than 350 separate exhibits, the museum is famous for its Panorama of North American Wildlife, part of w ... [...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 necessarily "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
