Wiehenvenator
''Wiehenvenator'' is a genus of megalosaurid theropod dinosaur from the Middle Jurassic (Callovian) of north western Germany. The genus contains a single species, ''W. albati''. Discovery and naming In 1998, geologist Friedrich Albat, prospecting for the Landschaftsverband Westfalen-Lippe Museum of Natural History, discovered the remains of a large theropod at the abandoned Pott quarry in the Wiehen Hills near Minden, Westphalia. The remains were discovered within the Ornatenton Formation, a geological formation composed mainly of mudstone, sandstones, and a horizon of carbonate concretions. The fragmentary theropod skeleton, found alongside abundant marine invertebrates and fossilized wood, was excavated between October 1998 and October 2001. At the time of their discovery, the bones were heavily weathered out of the surrounding sediments and are somewhat poorly preserved. The numerous breaks and cracks found in the material risked being destroyed upon removal from the matrix, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Megalosauridae
Megalosauridae is a monophyletic family of carnivorous theropod dinosaurs within the group Megalosauroidea. Appearing in the Middle Jurassic, megalosaurids were among the first major radiation of large theropod dinosaurs. They were a relatively primitive group of basal tetanurans containing two main subfamilies, Megalosaurinae and Afrovenatorinae, along with the basal genus ''Eustreptospondylus'', an unresolved taxon which differs from both subfamilies. The defining megalosaurid, ''Megalosaurus bucklandii'', was first named and described in 1824 by William Buckland after multiple finds in Stonesfield, Oxfordshire, UK. ''Megalosaurus'' was the first formally described dinosaur and was the basis for the establishment of the clade Dinosauria. It is also one of the largest known Middle Jurassic carnivorous dinosaurs, with the best-preserved femur at 805 mm and a proposed body mass of around 943 kg. Megalosauridae has mainly been recognized as a European group of dinosaurs, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornatenton Formation
The Ornatenton Formation is a Jurassic marine formation in Germany that is middle Callovian in age. The formation represents a shallow marine environment.Rauhut, Oliver W.M., Hübner, Tom R., and Lanser, Klaus-Peter, 2016, "A new megalosaurid theropod dinosaur from the late Middle Jurassic (Callovian) of north-western Germany: Implications for theropod evolution and faunal turnover in the Jurassic", ''Palaeontologia Electronica'' 19.2.26A: 1-65Mönnig, E. 1993, "Die Ornatenton-Formation in NW Deutschland."

Minden
Minden () is a middle-sized town in the very north-east of North Rhine-Westphalia, Germany, the greatest town between Bielefeld and Hanover. It is the capital of the district (''Kreis'') of Minden-Lübbecke, which is part of the region of Detmold. The town extends along both sides of the River Weser, and is crossed by the Mittelland Canal, which is passing the river on the Minden Aqueduct. In the 1,200 years longing time of written history, Minden had functions as diocesan town from 800 AD to the Peace of Westphalia in 1648, as capital of the Prince-Bishopric of Minden as imperial territory since the 12th century, afterwards as capital of the Prussian territory of Minden-Ravensberg until the end of the Holy Roman Empire in 1806, and as capital of the East-Westphalian region from the Congress of Vienna until 1947. Furthermore Minden has been of great military importance with fortifications from the 15th to the late 19th century, and is yet place of a garrison. Minden is locati ...

Callovian
In the geologic timescale, the Callovian is an age and stage in the Middle Jurassic, lasting between 166.1 ± 4.0 Ma (million years ago) and 163.5 ± 4.0 Ma. It is the last stage of the Middle Jurassic, following the Bathonian and preceding the Oxfordian. Stratigraphic definitions The Callovian Stage was first described by French palaeontologist Alcide d'Orbigny in 1852. Its name derives from the latinized name for Kellaways Bridge, a small hamlet 3 km north-east of Chippenham, Wiltshire, England. The base of the Callovian is defined as the place in the stratigraphic column where the ammonite genus ''Kepplerites'' first appears, which is the base of the biozone of '' Macrocephalites herveyi''. A global reference profile (a GSSP) for the base had in 2009 not yet been assigned. The top of the Callovian (the base of the Oxfordian) is at the first appearance of ammonite species '' Brightia thuouxensis''. Subdivision The Callovian is often subdivided into three substages ( ...

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.

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

Electronic Publication
Electronic publishing (also referred to as publishing, digital publishing, or online publishing) includes the digital publication of e-books, digital magazines, and the development of digital libraries and catalogues. It also includes the editing of books, journals, and magazines to be posted on a screen (computer, e-reader, tablet, or smartphone). About Electronic publishing has become common in scientific publishing where it has been argued that peer-reviewed scientific journals are in the process of being replaced by electronic publishing. It is also becoming common to distribute books, magazines, and newspapers to consumers through tablet reading devices, a market that is growing by millions each year, generated by online vendors such as Apple's iTunes bookstore, Amazon's bookstore for Kindle, and books in the Google Play Bookstore. Market research suggested that half of all magazine and newspaper circulation would be via digital delivery by the end of 2015 and that half of ...

Megalosauroidea
Megalosauroidea (meaning 'great/big lizard forms') is a superfamily (or clade) of tetanuran theropod dinosaurs that lived from the Middle Jurassic to the Late Cretaceous period. The group is defined as ''Megalosaurus bucklandii'' and all taxa sharing a more recent common ancestor with it than with ''Allosaurus fragilis'' or ''Passer domesticus''. Members of the group include ''Spinosaurus'', ''Megalosaurus'', and ''Torvosaurus''. They are possibly paraphyletic in nature. Classification The name Spinosauroidea is sometimes used in place of Megalosauroidea. The superfamily Spinosauroidea was named in 1915 by Ernst Stromer. It is a synonym of Megalosauroidea in almost all modern phylogenetic analyses, and it is therefore redundant. Spinosauroidea was defined as a clade in 1998 by Paul Sereno as the node clade containing the common ancestor of ''Spinosaurus'' and ''Torvosaurus'' and all its descendants. Thomas Holtz in 2004 defined a branch clade with the same name containing all spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Life Science Identifiers
Life Science Identifiers are a way to name and locate pieces of information on the web. Essentially, an LSID is a unique identifier for some data, and the LSID protocol specifies a standard way to locate the data (as well as a standard way of describing that data). They are a little like DOIs used by many publishers. An LSID is represented as a uniform resource name (URN) with the following format: * urn:lsid::: Controversy over the use of LSIDs |
