Temnodontosaurus Trigonodon
''Temnodontosaurus'' (Greek for "cutting-tooth lizard"temno, meaning "to cut", odont meaning "tooth" and sauros meaning "lizard") is an extinct genus of ichthyosaur from the Early Jurassic period. They lived between 200 and 175 million years ago (Hettangian-Toarcian) in what is now Western Europe, Western Europe (England, France, Luxembourg, Germany and Belgium) and possibly Chile. It lived in the deeper areas of the open ocean.Motani R.(2000). “Rulers of the Jurassic seas”. Scientific American. 283 (6): 52-59 University of Bristol paleontologist Jeremy Martin described the genus ''Temnodontosaurus'' as "one of the most ecologically disparate genera of ichthyosaurs," although the number of valid ''Temnodontosaurus'' species has varied over the years. ''Temnodontosaurus'' was one of the largest ichthyosaurs, with the type species (''T. platyodon'') reaching up to in maximum body length. It is known for its incredibly large eyes which, at approximately in diameter, are belie ... [...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 ...

Sir Everard Home
Sir Everard Home, 1st Baronet, FRS (6 May 1756, in Kingston upon Hull – 31 August 1832, in London) was a British surgeon. Home was born in Kingston-upon-Hull and educated at Westminster School. He gained a scholarship to Trinity College, Cambridge, but decided instead to become a pupil of his brother-in-law, John Hunter, at St George's Hospital. Hunter had married his sister, the poet and socialite Anne Home, in July 1771. He assisted Hunter in many of his anatomical investigations, and in the autumn of 1776 he partly described Hunter's collection. There is also considerable evidence that Home plagiarized Hunter's work, sometimes directly, sometimes indirectly; he also systematically destroyed his brother-in-law's papers in order to hide evidence of this plagiarism. It seems likely that the fire (in Home's apartments at Chelsea Hospital) which destroyed the Hunterian manuscripts in Home's possession also destroyed a precious collection of 26 microscopes originally made by ...

Thunnosauria
Thunnosauria (Greek for "tuna lizard" – ''thunnos'' meaning "tuna" and ''sauros'' meaning "lizard") is an extinct clade of parvipelvian ichthyosaurs from the Early Jurassic to the early Late Cretaceous ( Hettangian– Cenomanian) of Asia, Australia, Europe, North America, and South America. Named by Ryosuke Motani in 1999, it contains the basal taxa ''Ichthyosaurus'' and '' Stenopterygius'' and the family Ophthalmosauridae. In thunnosaurs, the fore fin is at least twice as long as the hind fin. Phylogeny Thunnosauria is a node-based taxon defined in 1999 as "the last common ancestor of '' Ichthyosaurus communis'' and ''Stenopterygius quadriscissus'' and all of its descendants". The cladogram A cladogram (from Greek ''clados'' "branch" and ''gramma'' "character") is a diagram used in cladistics to show relations among organisms. A cladogram is not, however, an evolutionary tree because it does not show how ancestors are related to ... below follows the topology fr ...

Temnodontosaurus Eurycephalus
''Temnodontosaurus eurycephalus'' is an extinct species of marine reptile. It is thought to have been a nektonic carnivore. Its name comes from the Greek ''ευρύς'', for "wide" and ''κεφαλή'' for "head". It possibly belongs to a new genus. Description It is considered a large ichthyosaur, the adult jaw length exceeding the mark. Its snout is relatively short, the ratio between the length of its snout to the length of its jaw being under 0.58. Its skull and lower jaw are deep; the orbit is relatively small, the ratio between the diameter of its orbit to the length of its jaw being lower than 0.21; in turn, the ratio between the internal diameter of its sclerotic ring to the diameter of its orbit is smaller than 0.35. The species maxilla is relatively long, the ratio between the length of its premaxilla to the length of its jaw is less than 0.36. Its naris is short. Its teeth are few in number, the maxillary tooth count probably standing at below 15. It belongs to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Saint Colombe
In religious belief, a saint is a person who is recognized as having an exceptional degree of holiness, likeness, or closeness to God. However, the use of the term ''saint'' depends on the context and denomination. In Catholic, Eastern Orthodox, Anglican, Oriental Orthodox, and Lutheran doctrine, all of their faithful deceased in Heaven are considered to be saints, but some are considered worthy of greater honor or emulation. Official ecclesiastical recognition, and consequently a public cult of veneration, is conferred on some denominational saints through the process of canonization in the Catholic Church or glorification in the Eastern Orthodox Church after their approval. While the English word ''saint'' originated in Christianity, historians of religion tend to use the appellation "in a more general way to refer to the state of special holiness that many religions attribute to certain people", referring to the Jewish tzadik, the Islamic walī, the Hindu rishi or Sikh gur ...

Species Inquirenda
In biological classification, a ''species inquirenda'' is a species of doubtful identity requiring further investigation. The use of the term in English-language biological literature dates back to at least the early nineteenth century. The term taxon inquirendum is broader in meaning and refers to an incompletely defined taxon of which the taxonomic validity is uncertain or disputed by different experts or is impossible to identify the taxon. Further characterization is required. See also * Glossary of scientific naming * ''Candidatus'', a proposed taxa based on incomplete evidence * ''incertae sedis'', a taxon of uncertain position in a classification * '' nomen dubium'', a name of unknown or doubtful application * Open nomenclature Open nomenclature is a vocabulary of partly informal terms and signs in which a taxonomist may express remarks about their own material. This is in contrast to synonymy lists, in which a taxonomist may express remarks on the work of others. Common . ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
