Plagiophthalmosuchus
''Plagiophthalmosuchus'' is a genus of teleosauroid, known form the Early Jurassic (Early Toarcian) Whitby Mudstone Formation of Whitby, Yorkshire, UK, and Dudelange, Luxembourg. The type species, ''P. gracilirostris'', was originally named as a species of ''Teleosaurus'' in 1836, but then it was moved to ''Steneosaurus ''Steneosaurus'' (from el, στενός , 'narrow' and el, σαῦρος , 'lizard') is a dubious genus of teleosaurid crocodyliform from the Middle or Late Jurassic (Callovian or early Oxfordian) of France.

Steneosaurus
''Steneosaurus'' (from el, στενός , 'narrow' and el, σαῦρος , 'lizard') is a dubious genus of teleosaurid crocodyliform from the Middle or Late Jurassic (Callovian or early Oxfordian) of France. The genus has been used as a wastebasket taxon for thalattosuchian fossils for over two centuries, and almost all known historical species of teleosauroid have been included within it at one point. The genus has remained a wastebasket, with numerous species still included under the label ''‘Steneosaurus’'', many of which are unrelated to each other (either paraphyletic or polyphyletic with respect to each other and other genera of teleosauroids). Discovery and assigned species The type species, ''S. rostromajor'', was only formally recognised as such in 2020, and this revision determined the type specimen of ''Steneosaurus'' was undiagnostic, and so declared the genus ''Steneosaurus'' a ''nomen dubium''. The history of this specimen has been detailed in 2017. It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Early Jurassic
The Early Jurassic Epoch (geology), Epoch (in chronostratigraphy corresponding to the Lower Jurassic series (stratigraphy), Series) is the earliest of three epochs of the Jurassic Period. The Early Jurassic starts immediately after the Triassic-Jurassic extinction event, 201.3 Ma (million years ago), and ends at the start of the Middle Jurassic 174.1 Ma. Certain rocks of marine origin of this age in Europe are called "Lias Group, Lias" and that name was used for the period, as well, in 19th-century geology. In southern Germany rocks of this age are called Black Jurassic. Origin of the name Lias There are two possible origins for the name Lias: the first reason is it was taken by a geologist from an England, English quarryman's dialect pronunciation of the word "layers"; secondly, sloops from north Cornwall, Cornish ports such as Bude would sail across the Bristol Channel to the Vale of Glamorgan to load up with rock from coastal limestone quarries (lias limestone from S ...

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] |

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Whitby
Whitby is a seaside town, port and civil parish in the Scarborough borough of North Yorkshire, England. Situated on the east coast of Yorkshire at the mouth of the River Esk, Whitby has a maritime, mineral and tourist heritage. Its East Cliff is home to the ruins of Whitby Abbey, where Cædmon, the earliest recognised English poet, lived. The fishing port emerged during the Middle Ages, supporting important herring and whaling fleets, and was where Captain Cook learned seamanship and, coincidentally, where his vessel to explore the southern ocean, ''The Endeavour'' was built.Hough 1994, p. 55 Tourism started in Whitby during the Georgian period and developed with the arrival of the railway in 1839. Its attraction as a tourist destination is enhanced by the proximity of the high ground of the North York Moors national park and the heritage coastline and by association with the horror novel '' Dracula''. Jet and alum were mined locally, and Whitby jet, which was mined by th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yorkshire
Yorkshire ( ; abbreviated Yorks), formally known as the County of York, is a Historic counties of England, historic county in northern England and by far the largest in the United Kingdom. Because of its large area in comparison with other English counties, functions have been undertaken over time by its subdivisions, which have also been subject to History of local government in Yorkshire, periodic reform. Throughout these changes, Yorkshire has continued to be recognised as a geographic territory and cultural region. The name is familiar and well understood across the United Kingdom and is in common use in the media and the Yorkshire Regiment, military, and also features in the titles of current areas of civil administration such as North Yorkshire, South Yorkshire, West Yorkshire and the East Riding of Yorkshire. Within the borders of the historic county of Yorkshire are large stretches of countryside, including the Yorkshire Dales, North York Moors and Peak District nationa ...

Dudelange
Dudelange (; lb, Diddeleng , german: Düdelingen) is a commune with town status in southern Luxembourg. It is the fourth-most populous commune, with 19,734 inhabitants. Dudelange is situated close to the border with France. , the town of Dudelange, which lies in the centre of the commune, has a population of 19,734, making it Luxembourg's third-most populous town. The commune also includes the smaller town of Budersberg, to the north-west. The Mont Saint-Jean, close to Budersberg, hosts the ruins of a medieval castle.

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.
