Dubreuillosaurus
''Dubreuillosaurus'' is a genus of carnivorous dinosaur from the middle Jurassic Period. It is a megalosaurid theropod. Its fossils were found in France. The only named species, ''Dubreuillosaurus valesdunensis'', was originally described as a species of ''Poekilopleuron'', ''Poekilopleuron? valesdunensis'', which is still formally the type species of the genus. It was later renamed ''Dubreuillosaurus valesdunensis'' when, in 2005, Allain came to the conclusion that it was not part of the genus ''Poekilopleuron''. Its type specimen, MNHN 1998-13, is only rivalled in the number of preserved elements in this group by that of ''Eustreptospondylus''. ''Dubreuillosaurus'' is considered to be the sister species of ''Magnosaurus''. It did not show signs of insular dwarfism even though it was uncovered on an island. Discovery and naming In 1994, the mayor of Conteville in Normandy, André Dubreuil, noted that during land rehabilitation of the old quarry of ''Pierre de Caen'', dinosaur b ...

Afrovenatorinae
Megalosauridae is a monophyletic family of carnivorous theropod dinosaurs within the group Megalosauroidea. Appearing in the Middle Jurassic, megalosaurids were among the first major radiation of large theropod dinosaurs. They were a relatively primitive group of basal tetanurans containing two main subfamilies, Megalosaurinae and Afrovenatorinae, along with the basal genus ''Eustreptospondylus'', an unresolved taxon which differs from both subfamilies. The defining megalosaurid, ''Megalosaurus bucklandii'', was first named and described in 1824 by William Buckland after multiple finds in Stonesfield, Oxfordshire, UK. ''Megalosaurus'' was the first formally described dinosaur and was the basis for the establishment of the clade Dinosauria. It is also one of the largest known Middle Jurassic carnivorous dinosaurs, with the best-preserved femur at 805 mm and a proposed body mass of around 943 kg. Megalosauridae has mainly been recognized as a European group of dinosaurs, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Magnosaurus
''Magnosaurus'' (meaning 'large lizard') was a genus of theropod dinosaur from the Middle Jurassic of England. It is based on fragmentary remains and has often been confused with or included in ''Megalosaurus''. History and taxonomy In 1923, Friedrich von Huene named ''Megalosaurus nethercombensis'' from a partial skeleton (OUM J12143) from the Bajocian age Middle Jurassic Inferior Oolite, found in the nineteenth century by W. Parker near Nethercomb, north of Sherborne, in Dorset, England. The material included partial dentaries, dorsal and caudal vertebrae, a partial ilium, a partial right pubis, internal casts of the femora, and tibiae, from a possible juvenile individual. Huene interpreted it as a more primitive species of ''Megalosaurus''.von Huene, F. (1923). Carnivorous Saurischia in Europe since the Triassic. ''Bulletin of the Geological Society of America'' 34:449-458. In 1926, he named the tooth species ''Megalosaurus lydekkeri'' for a specimen, BMNH 41352, from the ...

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 ...

Poekilopleuron
''Poekilopleuron'' (meaning "varied ribs") is a genus of tetanuran dinosaur, which lived during the middle Bathonian of the Jurassic, about 168 to 166 million years ago. The genus has been used under many different spelling variants, although only one, ''Poekilopleuron'', is valid. The type species is ''P. bucklandii'', named after William Buckland, and many junior synonyms of it have also been erected. Few material is currently known, as the holotype was destroyed in World War II, although many casts of the material still exist. Discovery and naming ''Poekilopleuron'' is a genus of theropod with a long and complex history. The holotype was discovered in July 1835 near La Maladrerie and the genus was named and first described by Jacques Amand Eudes-Deslongchamps in a report published in 1836, based on holotype material that is now destroyed. In 1837, Eudes-Deslongchamps published a more detailed account of this discovery in a monographEudes-Deslongchamps J.-A. (1837) Mémoire s ...
