Piveteausaurus Divesensis
''Piveteausaurus'' (meaning " Jean Piveteau's lizard") is a genus of theropod dinosaur known from a partial skull discovered in the Middle Jurassic Marnes de Dives formation of Calvados, in northern France and lived about 164.7-161.2 million years ago. In 2012 Thomas Holtz gave a possible length of 11 meters (36 feet). History and description The partial braincase that became the type specimen of ''Piveteausaurus'' was first described in 1923 by French paleontologist Jean Piveteau in illustrations and photographs of the specimen (MNHN 1920-7). The braincase is comparable in size to that of a large ''Allosaurus'', and resembles that of another megalosauroid, ''Piatnitzkysaurus'' from Argentina.Rauhut, 2004. Braincase structure of the Middle Jurassic theropod dinosaur ''Piatnitzkysaurus''. Canadian Journal of Earth Science. 41, 1109-1122. Piveteau grouped this partial skull with other specimens found earlier in that locality and described in 1808 by French naturalist Geor ...

Middle Jurassic
The Middle Jurassic is the second Epoch (geology), epoch of the Jurassic Period (geology), Period. It lasted from about 174.1 to 161.5 million years ago. Fossils of land-dwelling animals, such as dinosaurs, from the Middle Jurassic are relatively rare, but geological formations containing land animal fossils include the Forest Marble Formation in England, the Kilmaluag Formation in Scotland,British Geological Survey. 2011Stratigraphic framework for the Middle Jurassic strata of Great Britain and the adjoining continental shelf: research report RR/11/06 British Geological Survey, Keyworth, Nottingham. the Calcaire de Caen of France, the Daohugou Beds in China, the Itat Formation in Russia, the Tiouraren Formation of Niger, and the Isalo III Formation of western Madagascar.

Type Specimen
In biology, a type is a particular wikt:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set (mathematics), set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN), the ...

Marcellin Boule
Pierre-Marcellin Boule (1 January 1861 – 4 July 1942), better known as merely Marcellin Boule, was a French palaeontologist, geologist, and anthropologist. Early life and education Pierre-Marcellin Boule was born in Montsalvy, France. Career Boule was a professor at the Muséum National d’Histoire Naturelle, Paris (1902–1936) and "for many years director of the Institut de Paléontologie Humaine, Paris." He was an editor (1893–1940) of the journal ''L’Anthropologie'' and was the founder of two other scientific journals. Boule studied and published in 1911 the first analysis of a complete Neanderthal specimen. The fossil discovered in La Chapelle-aux-Saints was an old man, and Boule characterized it as brutish, bent-kneed and not a fully erect biped. In an illustration Boule commissioned, the Neanderthal was characterized as a hairy gorilla-like figure with opposable toes, according to a skeleton which was already distorted with arthritis Arthritis is a ge ...

Dives-sur-Mer
Dives-sur-Mer (, literally ''Dives on Sea''; ) is a commune in the Calvados department in Normandy in northwestern France. History It was from the harbour of Dives-sur-Mer that William the Conqueror set out on the Norman Conquest of England in 1066. On the night before sailing to Pevensey Bay for battle, William and 475 barons and knights from Normandy, Flanders, and Brittany attended Dives-sur-Mer Church for Mass and prayers. After much research in the 18th century, the French government placed a monumental plaque in the church listing by name all 475 companions of the Conqueror on that great mission Book One of "One Family's Journey Through Ten Centuries, by William Lilly contains analysis at Appendix d, p. 1395 of the efforts to determine who those knights were. The medieval wooden market hall and the 13th-14th-century church are the main attractions of the town.

Oxfordian Stage
The Oxfordian is, in the ICS' geologic timescale, the earliest age of the Late Jurassic Epoch, or the lowest stage of the Upper Jurassic Series. It spans the time between 161.5 ± 1.0 Ma and 154.8 ± 0.8 Ma (million years ago). The Oxfordian is preceded by the Callovian and is followed by the Kimmeridgian. Stratigraphic definitions The Oxfordian Stage was called "Clunch Clay and Shale" by William Smith (1815–1816); in 1818 W. Buckland described them under the unwieldy title "Oxford, Forest or Fen Clay". The term Oxfordian was introduced by Alcide d'Orbigny in 1844. The name is derived from the English city of Oxford, where the beds are well developed, but they crop out almost continuously from Dorset to the coast of Yorkshire, generally forming low, broad valleys. They are well exposed at Weymouth, Oxford, Bedford, Peterborough, and in the cliffs at Scarborough, Red Cliff and Gristhorpe Bay. Rocks of this age are found also in Uig and Skye.

Streptospondylus
''Streptospondylus'', from Ancient Greek στρεπτός (''streptós''), meaning "twisted", and σπόνδυλος (''spóndulos''), meaning "vertebra", is a genus of tetanuran theropod dinosaur known from the Late Jurassic period of France, 161 million years ago. It was a medium-sized predator with an estimated length of 6 meters (19.5 ft) and a weight of 500 kg (1,100 lbs). Discovery and naming ''Streptospondylus'' was one of the first dinosaurs collected and was the first described, though not the first dinosaur named. It was not recognised as a theropod dinosaur until 2001. In 1778, abbey Charles Bacheley, a Norman naturalist, reported the presence of fossil bones in the Callovo-Oxfordian formations, either the Marnes de Dives or the overlying Marnes de Villers, probably the former, exposed at the foot of the Vaches Noires cliffs between Villers-sur-Mer and Houlgate.Brignon, A.

Richard Owen
Sir Richard Owen (20 July 1804 – 18 December 1892) was an English biologist, comparative anatomy, comparative anatomist and paleontology, palaeontologist. Owen is generally considered to have been an outstanding naturalist with a remarkable gift for interpreting fossils. Owen produced a vast array of scientific work, but is probably best remembered today for coining the word ''Dinosauria'' (meaning "Terrible Reptile" or "Fearfully Great Reptile"). An outspoken critic of Charles Darwin's theory of evolution by natural selection, Owen agreed with Darwin that evolution occurred but thought it was more complex than outlined in Darwin's ''On the Origin of Species''.[''Wikipedia:Citing sources, page range too broad''] Owen's approach to evolution can be considered to have anticipated the issues that have gained greater attention with the recent emergence of evolutionary developmental biology. Owen was the first president of the Microscopical Society of London in 1839 and edited ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Georges Cuvier
Jean Léopold Nicolas Frédéric, baron Cuvier (23 August 1769 – 13 May 1832), known as Georges Cuvier (; ), was a French natural history, naturalist and zoology, zoologist, sometimes referred to as the "founding father of paleontology". Cuvier was a major figure in natural sciences research in the early 19th century and was instrumental in establishing the fields of comparative anatomy and paleontology through his work in comparing living animals with fossils. Cuvier's work is considered the foundation of vertebrate paleontology, and he expanded Linnaean taxonomy by grouping classes into phylum, phyla and incorporating both fossils and living species into the classification. Cuvier is also known for establishing extinction as a fact—at the time, extinction was considered by many of Cuvier's contemporaries to be merely controversial speculation. In his ''Essay on the Theory of the Earth'' (1813) Cuvier proposed that now-extinct species had been wiped out by periodic catastr ...

Piatnitzkysaurus
''Piatnitzkysaurus'' ( ; meaning "Piatnitzky's lizard") is a genus of tetanuran theropod dinosaur that lived approximately 179 to 177 million years ago during the lower part of the Jurassic Period in what is now Argentina. ''Piatnitzkysaurus'' was a moderately large, lightly built, bipedal, ground-dwelling carnivore that could grow over long. Discovery and naming The holotype specimen of ''Piatnitzkysaurus'', PVL 4073, was collected during expeditions in 1977, 1982, and 1983 at the Cañadón Asfalto Formation in sediments that were deposited during the Middle-Late Toarcian stage of the Jurassic period, approximately 179 to 177 million years ago.Bonaparte, J. F. (1979)Dinosaurs: a Jurassic assemblage from Patagonia.''Science'', ''205''(4413), 1377-1379.
