Proceratosaurus
''Proceratosaurus'' is a genus of carnivore, carnivorous theropod dinosaur from the Middle Jurassic (Bathonian) of England. ''Proceratosaurus'' was a small dinosaur, measuring in length and in body mass.Holtz, Thomas R. Jr. (2008) ''Dinosaurs: The Most Complete, Up-to-Date Encyclopedia for Dinosaur Lovers of All Ages'Supplementary Information Its name refers to how it was originally thought to be an ancestor of ''Ceratosaurus'', due to the partially preserved portion of the crest of ''Proceratosaurus'' superficially resembling the small crest of ''Ceratosaurus''. Now, however, it is considered a coelurosaur, specifically a member of the family Proceratosauridae, and amongst the earliest known members of the clade Tyrannosauroidea. The type specimen is held in the Natural History Museum, London, Natural History Museum in London and was described in 1910 in paleontology, 1910 from Oolite, oolitic limestone of the Great Oolite Group near Minchinhampton while excavating for a reser ...

Proceratosauridae
Proceratosauridae is a Family (biology), family or clade of Tyrannosauroidea, tyrannosauroid theropod dinosaurs from the Middle Jurassic to the Early Cretaceous. Distinguishing features Unlike the advanced Tyrannosauridae, tyrannosaurids but similar to primitive Tyrannosauroidea, tyrannosauroids like ''Dilong (dinosaur), Dilong'', proceratosaurids were generally small (with the exception of the possible proceratosaurids ''Yutyrannus'' and ''Sinotyrannus'') and had fairly long, three-fingered arms capable of grasping prey. In comparison to other members of Tyrannosauroidea, proceratosaurids can be distinguished by the following features according to phylogenetic analyses by Averianov ''et al''. (2010) and Loewen ''et al''. (2013) : * A sagittal cranial crest formed by the Nasal bone, nasals starting at the junction of the premaxilla and nasals. * Extremely elongated external nares, with posterior margins posterior to the anterior margin of the antorbital fossa and maxillary fenes ...

Tyrannosauroidea
Tyrannosauroidea (meaning 'tyrant lizard forms') is a superfamily (or clade) of coelurosaurian theropod dinosaurs that includes the family Tyrannosauridae as well as more basal relatives. Tyrannosauroids lived on the Laurasian supercontinent beginning in the Jurassic Period. By the end of the Cretaceous Period, tyrannosauroids were the dominant large predators in the Northern Hemisphere, culminating in the gigantic ''Tyrannosaurus''. Fossils of tyrannosauroids have been recovered on what are now the continents of North America, Europe and Asia, with fragmentary remains possibly attributable to tyrannosaurs also known from South America and Australia. Tyrannosauroids were bipedal carnivores, as were most theropods, and were characterized by numerous synapomorphy, skeletal features, especially of the skull and pelvis. Early in their existence, tyrannosauroids were small predators with long, three-fingered forelimbs. Late Cretaceous genera became much larger, including some of the ...

Ceratosaurus
''Ceratosaurus'' (from Ancient Greek, Greek κέρας/κέρατος, ' meaning "horn" and wikt:σαῦρος, σαῦρος ' meaning "lizard") was a carnivorous Theropoda, theropod dinosaur in the Late Jurassic Period (geology), period (Kimmeridgian to Tithonian). The genus (biology), genus was first described in 1884 by American paleontologist Othniel Charles Marsh based on a nearly complete skeleton discovered in Garden Park, Colorado, in rocks belonging to the Morrison Formation. The type species is ''Ceratosaurus nasicornis''. The Garden Park specimen remains the most complete skeleton known from the genus, and only a handful of additional specimens have been described since. Two additional species, ''Ceratosaurus dentisulcatus'' and ''Ceratosaurus magnicornis'', were described in 2000 from two fragmentary skeletons from the Cleveland-Lloyd Dinosaur Quarry, Cleveland-Lloyd Quarry of Utah and from the vicinity of Fruita, Colorado.

Minchinhampton
Minchinhampton is an ancient Cotswolds market town in the Stroud District in Gloucestershire, South West England. The town is located on a hilltop, south-east of Stroud. The common offers wide views over the Severn Estuary into Wales and further into the Cotswolds. Toponymy The place-name 'Minchinhampton' is first attested as ''Hantone'' in the Domesday Book of 1086. It appears as ''Minchenhamtone'' in the Assize Rolls of 1221. The name was originally the Old English ''Heatun'', meaning "high town or settlement". The additional element is the Old English ''mynecen'', meaning a nun, which is related to the modern word "monk". Minchinhampton at one time belonged to the nunnery in Caen in Normandy, France. Thus the name means "the nuns' high town or settlement". . On a map of 1825 (published 1828) the town is labelled "Minching-Hampton" (see external links). Amenities and features The main square has a war memorial, and a 17th-century Market House, given to the town in 1919 by t ...

Megalosaurus
''Megalosaurus'' (meaning "great lizard", from Greek , ', meaning 'big', 'tall' or 'great' and , ', meaning 'lizard') is an extinct genus of large carnivorous theropod dinosaurs of the Middle Jurassic period (Bathonian stage, 166 million years ago) of Southern England. Although fossils from other areas have been assigned to the genus, the only certain remains of ''Megalosaurus'' come from Oxfordshire and date to the late Middle Jurassic. ''Megalosaurus'' was, in 1824, the first genus of non-avian dinosaur to be validly named. The type species is ''Megalosaurus bucklandii'', named in 1827. In 1842, ''Megalosaurus'' was one of three genera on which Richard Owen based his Dinosauria. On Owen's directions a model was made as one of the Crystal Palace Dinosaurs, which greatly increased the public interest for prehistoric reptiles. Over fifty other species would eventually be classified under the genus; at first, this was because so few types of dinosaur had been identified, but the p ...

Great Oolite Group
The Great Oolite Group is a Middle Jurassic stratigraphic unit that outcrops in southern England. It consists of a complex set of marine deposits primarily mudstone and bioclastic ooidal and fine grained limestone, deposited in nearshore to shelf settings. It is exposed at the surface as a variably thick belt extending roughly NE-SW from the coast of Dorset up to the Humber. It is also present at depth in the Weald and Wessex Basins, as well as offshore. Several of the constituent formations, notably the Taynton Limestone Formation and the Forest Marble Formation are notable for their fossil content, including those of dinosaurs and pterosaurs and some of the earliest mammals.

Coelurosaur
Coelurosauria (; from Greek, meaning "hollow tailed lizards") is the clade containing all theropod dinosaurs more closely related to birds than to carnosaurs. Coelurosauria is a subgroup of theropod dinosaurs that includes compsognathids, tyrannosaurs, ornithomimosaurs, and maniraptorans; Maniraptora includes birds, the only known dinosaur group alive today. Most feathered dinosaurs discovered so far have been coelurosaurs. Philip J. Currie had considered it likely and probable that all coelurosaurs were feathered. However, several skin impressions found for some members of this group show pebbly, scaly skin, indicating that feathers did not completely replace scales in all taxa. In the past, Coelurosauria was used to refer to all small theropods, but this classification has since been abolished. Anatomy Bodyplan The studying of anatomical traits in coelurosaurs indicates that the last common ancestor had evolved the ability to eat and digest plant matter, adapting to an omnivo ...

Friedrich Von Huene
Friedrich von Huene, born Friedrich Richard von Hoinigen, (March 22, 1875 – April 4, 1969) was a German paleontologist who renamed more dinosaurs in the early 20th century than anyone else in Europe. He also made key contributions about various Permo-Carboniferous limbed vertebrates. Biography Huene was born in Tübingen, Kingdom of Württemberg. His discoveries include the skeletons of more than 35 individuals of ''Plateosaurus'' in the famous Trossingen quarry, the early proto-dinosaur ''Saltopus'' in 1910, ''Proceratosaurus'' in 1926, the giant ''Antarctosaurus'' in 1929, and numerous other dinosaurs and fossilized animals like pterosaurs. He also was the first to naming several higher taxa, including Prosauropoda and Sauropodomorpha. In 1941 he found a stone that had petrified wood in it, sadly, He thought that it was a dinosaur. However a couple Polish paleontologists. The “dinosaur” was called the Succinodon He visited the Geopark of Paleorrota in 1928, and the ...

Cotswolds
The Cotswolds (, ) is a region in central-southwest England, along a range of rolling hills that rise from the meadows of the upper Thames to an escarpment above the Severn Valley and Evesham Vale. The area is defined by the bedrock of Jurassic limestone that creates a type of grassland habitat rare in the UK and that is quarried for the golden-coloured Cotswold stone. The predominantly rural landscape contains stone-built villages, towns, and stately homes and gardens featuring the local stone. Designated as an Area of Outstanding Natural Beauty (AONB) in 1966, the Cotswolds covers making it the largest AONB. It is the third largest protected landscape in England after the Lake District and Yorkshire Dales national parks. Its boundaries are roughly across and long, stretching southwest from just south of Stratford-upon-Avon to just south of Bath near Radstock. It lies across the boundaries of several English counties; mainly Gloucestershire and Oxfordshire, and parts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
