Eretmosaurus Rugosus
''Eretmosaurus'' (meaning "oar lizard") is an extinct genus of plesiosaur from the Early and Middle Jurassic of England and Russia. Two species are known: ''E. rugosus'' and ''E. dubius''. History ''Eretmosaurus rugosus'' The holotype of ''E. rugosus'' consists of vertebrae, girdles, and limb bones and was discovered along Aust Cliff, where the Westbury Formation outcrops. Specimen BRSMB Cb 2458 was also assigned to the species by Owen (1840). This specimen later became the syntype and it consisted of several vertebrae that had been discovered at different locations in the Blue Lias in Gloucestershire. Owen (1840) was the first to describe the specimens, which were named as ''Plesiosaurus rugosus''.R. Owen. (1840). Report on British fossil reptiles. ''Report of the Ninth Meeting of the British Association for the Advancement of Science, Reports on the State of Science'' 43-126 Later, Owen (1865) described a headless skeleton discovered in the Ammonites stellaris zone of ...

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 174.7 ±0.8 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 and Carbonif ...

Fossils of the genus have been found in France, the Posidonia Shale in Germany and Luxembourg, and the Alum Shale Formation of England. Description The type species, ''M. homalospondylus'', was the largest, measuring long and weighing . Other species were smaller: ''M. tournemirensis'' was about long and weighed , and ''M. melusinae'' was about long and weighed . Classification Species include: ''Microcleidus homalospondylus'' (Owen 1865) and ''Microcleidus macropterus'' (Seeley 1865). ''Occitanosaurus tournemirensis'' (originally ''"Plesiosaurus" tournemirensis''), was named by Sciau ''et al.'' in 1990, based on a nearly complete skeleton of an animal approximately 4 meters (13 ft) long.Ketchum HF, Benson RBJ.

Siberia
Siberia ( ; , ) is an extensive geographical region comprising all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east. It has formed a part of the sovereign territory of Russia and its predecessor states since the lengthy conquest of Siberia, which began with the fall of the Khanate of Sibir in 1582 and concluded with the annexation of Chukotka in 1778. Siberia is vast and sparsely populated, covering an area of over , but home to roughly a quarter of Russia's population. Novosibirsk, Krasnoyarsk, and Omsk are the largest cities in the area. Because Siberia is a geographic and historic concept and not a political entity, there is no single precise definition of its territorial borders. Traditionally, Siberia spans the entire expanse of land from the Ural Mountains to the Pacific Ocean, with the Ural River usually forming the southernmost portion of its western boundary, and includes most of the drainage basin of the Arctic Ocean.

ICZN
The International Code of Zoological Nomenclature (ICZN) is a widely accepted convention in zoology that rules the formal scientific naming of organisms treated as animals. It is also informally known as the ICZN Code, for its formal author, the International Commission on Zoological Nomenclature (which shares the acronym "ICZN"). The rules principally regulate: * How names are correctly established in the frame of binominal nomenclature * How to determine whether a given name is available * Which available name must be used in case of name conflicts ( valid name) * How scientific literature must cite names Zoological nomenclature is independent of other systems of nomenclature, for example botanical nomenclature. This implies that animals can have the same generic names as plants (e.g. there is a genus '' Abronia'' in both animals and plants). The rules and recommendations have one fundamental aim: to provide the maximum universality and continuity in the naming of all anima ...

Blue Lias
The Blue Lias is a formation (stratigraphy), geological formation in southern, eastern and western England and parts of South Wales, part of the Lias Group. The Blue Lias consists of a sequence of limestone and shale layers, laid down in latest Triassic and early Jurassic times, between 195 and 200 million years ago. The Blue Lias is famous for its fossils, especially ammonites. Its age corresponds to the Rhaetian to lower Sinemurian stages of the geological timescale, thus fully including the Hettangian stage. It is the lowest of the three divisions of the Lower Jurassic period and, as such, is also given the name ''Lower Lias''. stratigraphy, Stratigraphically it can be subdivided into three Geological unit#Lithostratigraphic units, members: the Wilmcote Limestone, Saltford Shale and Rugby, Warwickshire, Rugby Limestone.
