Piveteausaurus
''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 (stratigraphy), formation of Calvados (department), 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 Paleontology, paleontologist Jean Piveteau in illustrations and photographs of the specimen (Muséum national d'histoire naturelle, 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.

Streptospondylus
''Streptospondylus'' (meaning "reversed 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.

Marnes De Dives
The Marnes de Dives is a geological formation in Normandy, France. It dates back to the upper part of the Callovian stage of the Middle Jurassic.Weishampel, David B; et al. (2004). "Dinosaur distribution (Middle Jurassic, Europe)." In: Weishampel, David B.; Dodson, Peter; and Osmólska, Halszka (eds.): The Dinosauria, 2nd, Berkeley: University of California Press. Pp. 538–541. . And is partially equivalent to the Oxford Clay in England. It predominantly consists of ooidal marl, rich in pyrite and lignite, interbedded with thin limestone horizons. It is best exposed at the base of the Falaises des Vaches Noires (Cliffs of Black Cows) as well as the foreshore at low tide. It is known for its fossils, notably those of ammonites, marine crocodiles and fragmentary remains of dinosaurs, mostly theropods.

Eustreptospondylus
''Eustreptospondylus'' ( ; meaning "true ''Streptospondylus''") is a genus of megalosaurid Theropoda, theropod dinosaur, from the Oxfordian stage of the Late Jurassic period (some time between 163 and 154 million years ago) in southern England, at a time when Europe was a series of scattered islands (due to tectonic movement at the time which raised the sea-bed and flooded the lowland). Discovery and naming In 1870, workers at the Summertown Brick Pit, just north of Oxford, England, found the skeleton of a theropod. The remains were acquired by the local bookseller James Parker, who brought them to the attention of Oxford Professor John Phillips (geologist), John Phillips. Phillips described the bones in 1871, but did not name them. At the time, the remains represented the most complete skeleton of a large theropod ever found. ''Eustreptospondylus'' is still the most complete of any large Jurassic European theropod. In 1890, the skeleton was bought by Oxford University, a ...

Piatnitzkysaurus
''Piatnitzkysaurus'' ( meaning "Piatnitzky's lizard") is a genus of megalosauroid 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 up to 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.

Allosaurus
''Allosaurus'' () is a genus of large carnosaurian theropod dinosaur that lived 155 to 145 million years ago during the Late Jurassic epoch (Kimmeridgian to late Tithonian). The name "''Allosaurus''" means "different lizard" alluding to its unique (at the time of its discovery) concave vertebrae. It is derived from the Greek (') ("different, other") and (') ("lizard / generic reptile"). The first fossil remains that could definitively be ascribed to this genus were described in 1877 by paleontologist Othniel Charles Marsh. As one of the first well-known theropod dinosaurs, it has long attracted attention outside of paleontological circles. ''Allosaurus'' was a large bipedal predator. Its skull was light, robust and equipped with dozens of sharp, serrated teeth. It averaged in length for ''A. fragilis'', with the largest specimens estimated as being long. Relative to the large and powerful hindlimbs, its three-fingered forelimbs were small, and the body was balanced b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Houlgate
Houlgate () is a small tourist resort in northwestern France along the English Channel with a beach and a casino. It is a commune in the Calvados department in the Normandy region. History Pre-19th century Houlgate developed as a hamlet in the commune of Beuzeval. Up until the 19th century, Beuzeval consisted of only a few small houses and farms. On the southern side of the stream was Le Hameau de la Mer, consisting of a few houses, a tile and brick works and a water mill. In 1793, only 204 inhabitants lived in the commune. 19th century: development as a resort Between 1845 and 1850, sea bathing became popular in Beuzeval. The Pilter family opened the first guesthouse for poorer protestant families in 1851 on Rue Sébastien-de-Neufville. Numbers of tourists gradually increased, first from Caen and then Paris and so a wooden boarding house was built. The sea-side village was named Beuzeval-les-Bains and attracted much Protestant gentry. The population increased from the 1860s ...

Richard Owen
Sir Richard Owen (20 July 1804 – 18 December 1892) was an English biologist, comparative anatomist and paleontologist. 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''. 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 many issues of its journal – then known as ''The Microscopic Journal''. Owen also c ...
