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. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Neosteneosaurus
''Neosteneosaurus'' is a genus of machimosaurid, known from the Middle Jurassic Oxford Clay of the UK, and Marnes de Dives, France. The type species, ''N. edwardsi'', was originally named as a species of ''Steneosaurus'' in 1868, but was moved to its own genus in 2020. ''Steneosaurus durobrivensis'' and ''Steneosaurus hulkei'' are considered junior synonym The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnae ...s. In 2015, it was estimated at more than in length. In 2016, this estimate was revised down to , but even with such measurement, this animal remains to be the largest known Middle Jurassic crocodylomorph.

Christian Erich Hermann Von Meyer
Christian Erich Hermann von Meyer (3 September 1801 – 2 April 1869), known as Hermann von Meyer, was a German palaeontologist. He was awarded the 1858 Wollaston medal by the Geological Society of London. Life He was born at Frankfurt am Main. In 1832, Meyer issued a work entitled ''Palaeologica'', and in course of time he published a series of memoirs on various fossil organic remains: molluscs, crustaceans, fishes and higher vertebrata, including the Triassic predator ''Teratosaurus'', the earliest bird ''Archaeopteryx lithographica'' (1861), the pterosaur ''Rhamphorhynchus'', and the prosauropod dinosaur ''Plateosaurus''. In ''Palaeologica'', Meyer proposed a classification of fossil reptiles into four major groups based on their limbs: *Saurians with Toes Similar to those of Living Species (e.g.''Teleosaurus'', ''Protorosaurus'', ''Streptospondylus'') *Saurians with Limbs Similar to Heavy Land Mammals ('' Iguanodon'', ''Megalosaurus'') *Saurians with Limbs for Sw ...

Isaac Newton
Sir Isaac Newton (25 December 1642 – 20 March 1726/27) was an English mathematician, physicist, astronomer, alchemist, Theology, theologian, and author (described in his time as a "natural philosophy, natural philosopher"), widely recognised as one of the greatest mathematicians and physicists and among the most influential scientists of all time. He was a key figure in the philosophical revolution known as the Age of Enlightenment, Enlightenment. His book (''Mathematical Principles of Natural Philosophy''), first published in 1687, established classical mechanics. Newton also made seminal contributions to optics, and Multiple discovery, shares credit with German mathematician Gottfried Wilhelm Leibniz for developing calculus, infinitesimal calculus. In the , Newton formulated the Newton's laws of motion, laws of motion and Newton's law of universal gravitation, universal gravitation that formed the dominant scientific viewpoint for centuries until it was supersede ...
