Criorhynchus
''Ornithocheirus'' (from Ancient Greek "ὄρνις", meaning ''bird'', and "χεῖρ", meaning ''hand'') is a pterosaur genus known from fragmentary fossil remains uncovered from sediments in the UK and possibly Morocco. Several species have been referred to the genus, most of which are now considered as dubious species, or members of different genera, and the genus is now often considered to include only the type species, ''Ornithocheirus simus''. Species have been referred to ''Ornithocheirus'' from the mid-Cretaceous period of both Europe and South America, but ''O. simus'' is known only from the UK, though a specimen referred to ''O.'' cf. ''simus'' is also known from Morocco. Because ''O. simus'' was originally named based on poorly preserved fossil material, the genus ''Ornithocheirus'' has suffered enduring problems of zoological nomenclature. Fossil remains of ''Ornithocheirus'' have been recovered mainly from the Cambridge Greensand of England, dating to the beginni ...

Coloborhynchus
''Coloborhynchus'' is a genus of pterodactyloid pterosaur belonging to the family Anhangueridae, though it has also been recovered as a member of the Ornithocheiridae in some studies. ''Coloborhynchus'' is known from the Lower Cretaceous of England (Valanginian age, 140 to 136 million years ago), and depending on which species are included, possibly the Albian and Cenomanian ages (113 to 93.9 million years ago) as well. ''Coloborhynchus'' was once thought to be the largest known toothed pterosaur, however, a specimen of the closely related ''Tropeognathus'' is now thought to have had a larger wingspan. History and classification Like many ornithocheiroid pterosaurs named during the 19th century, ''Coloborhynchus'' has a highly convoluted history of classification. Over the years numerous species have been assigned to it, and often, species have been shuffled between ''Coloborhynchus'' and related genera by various researchers. In 1874 Richard Owen, rejecting the creation by H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropeognathus
''Tropeognathus'' (meaning "keel jaw") is a genus of large pterosaurs from the late Early Cretaceous of South America. This genus is considered to be a member of the family Anhangueridae, however, several studies have also recovered it within another family called Ornithocheiridae. Both of these families are diverse groups of pterosaurs known for their keel-tipped snouts and large size. ''Tropeognathus'' is regarded as the largest pterosaur found in the Southern Hemisphere, only rivaled by the huge azhdarchids. The type and only species is ''Tropeognathus mesembrinus''. Fossil remains of ''Tropeognathus'' have been recovered from the Romualdo Formation, which is a Lagerstätte located in the Santana Group of the Araripe Basin in northeastern Brazil. Discovery and naming In the 1980s the German paleontology museum '' Bayerische Staatssammlung für Paläontologie und historische Geologie'' in Munich acquired a pterosaur skull from Brazilian fossil dealers that had probably bee ...

Early Cretaceous
The Early Cretaceous ( geochronological name) or the Lower Cretaceous (chronostratigraphic name), is the earlier or lower of the two major divisions of the Cretaceous. It is usually considered to stretch from 145 Ma to 100.5 Ma. Geology Proposals for the exact age of the Barremian-Aptian boundary ranged from 126 to 117 Ma until recently (as of 2019), but based on drillholes in Svalbard the defining early Aptian Oceanic Anoxic Event 1a (OAE1a) was carbon isotope dated to 123.1±0.3 Ma, limiting the possible range for the boundary to c. 122–121 Ma. There is a possible link between this anoxic event and a series of Early Cretaceous large igneous provinces (LIP). The Ontong Java-Manihiki-Hikurangi large igneous province, emplaced in the South Pacific at c. 120 Ma, is by far the largest LIP in Earth's history. The Ontong Java Plateau today covers an area of 1,860,000 km2. In the Indian Ocean another LIP began to form at c. 120 Ma, the Kerguelen P ...

Santana Formation
The Santana Group is a geologic group, formerly included as the middle part of the Araripe Group, in the Araripe Basin of northeastern Brazil. The group comprises the Crato, Ipubi and Romualdo Formations and is dated to the Aptian to Albian stages of the Early Cretaceous. The formations of the group were deposited in a lacustrine to subtidal shallow marine environment in the Araripe rift basin.Santana Group at Fossilworks.org The Santana Group has provided a rich assemblage of fossils; flora, fish, arthropods insects, turtles, snakes, dinosaurs, such as '' |
Reginald Walter Hooley
Reginald Walter Hooley (5 September 1865 – 5 May 1923) was a businessman and amateur paleontologist, collecting on the Isle of Wight. He is probably best remembered for describing the dinosaur ''Iguanodon atherfieldensis'', now ''Mantellisaurus.'' Biography Reginald Hooley was born on 5 September 1865 in Southampton, the son of William Hooley, a wealthy gentleman. In 1889 R.W. Hooley began to work for ''Godrich & Petman'', wine merchants, and later in life became managing director of that firm. Living in Portswood, in 1912 he married E.E. Holden and moved to Winchester. In 1913 he was elected a member of the Winchester city council. Hooley was a member of the Hampshire Field Club & Archaeological Society at Winchester from 1890. He was one of the founders of the Isle of Wight Natural History and Archaeological Society. He was an honorary curator of the Winchester Museum between 1918 and 1923. Isle of Wight Hooley made regular visits to the Isle of Wight and found hundreds of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Drinker Cope
Edward Drinker Cope (July 28, 1840 – April 12, 1897) was an American zoologist, paleontologist, comparative anatomist, herpetologist, and ichthyologist. Born to a wealthy Quaker family, Cope distinguished himself as a child prodigy interested in science; he published his first scientific paper at the age of 19. Though his father tried to raise Cope as a gentleman farmer, he eventually acquiesced to his son's scientific aspirations. Cope married his cousin and had one child; the family moved from Philadelphia to Haddonfield, New Jersey, although Cope would maintain a residence and museum in Philadelphia in his later years. Cope had little formal scientific training, and he eschewed a teaching position for field work. He made regular trips to the American West, prospecting in the 1870s and 1880s, often as a member of United States Geological Survey teams. A personal feud between Cope and paleontologist Othniel Charles Marsh led to a period of intense fossil-finding competition ...

Pteranodon
''Pteranodon'' (); from Ancient Greek (''pteron'', "wing") and (''anodon'', "toothless") is a genus of pterosaur that included some of the largest known flying reptiles, with ''P. longiceps'' having a wingspan of . They lived during the late Cretaceous geological period of North America in present-day Kansas, Nebraska, Wyoming, South Dakota and Alabama. More fossil specimens of ''Pteranodon'' have been found than any other pterosaur, with about 1,200 specimens known to science, many of them well preserved with nearly complete skulls and articulated skeletons. It was an important part of the animal community in the Western Interior Seaway. ''Pteranodon'' was not a dinosaur. By definition, all dinosaurs belong to the group Dinosauria; ''Pteranodon'' belongs to the group Pterosauria. Nonetheless, ''Pteranodon'' is the most famous pterosaur, frequently featured in dinosaur media and strongly associated with dinosaurs by the general public. While not dinosaurs, pterosaurs such as ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edwin Tulley Newton
Edwin Tulley Newton (4 May 1840 – 28 January 1930) was a British paleontologist. Newton originally worked at handicrafts, but was able to attend Thomas Henry Huxley's lectures and by 1865, was appointed as his assistant. In 1882, he became paleontologist to the "Geologic Survey", a position he retained until 1905. His early work included microscopic sectioning of coal and notable studies on cockroach brains. Later he did work on chimaeroid fish fossils. In 1893, Newton won the Lyell Medal. He was president of the Geologists' Association in 1896–1898 and president of the Palaeontographical Society from 1921 to 1928. Newton was elected Fellow of the Geological Society in 1873, Zoological Society of London in 1885, and Fellow of the Royal Society Fellowship of the Royal Society (FRS, ForMemRS and HonFRS) is an award granted by the judges of the Royal Society of London to individuals who have made a "substantial contribution to the improvement of natural science, natu ...

Ornithocheirus Buenzeli
"''Ornithocheirus''" ''buenzeli'' (often mis-spelled ''O. bunzeli''Averianov, A.O. (2010).The osteology of ''Azhdarcho lancicollis'' Nessov, 1984 (Pterosauria, Azhdarchidae) from the Late Cretaceous of Uzbekistan" ''Proceedings of the Zoological Institute of the Russian Academy of Sciences'', 314(3): 246-317.) is a pterosaur species known from parts of a humerus (upper arm bone) and part of a lower jaw found in late Cretaceous period (Campanian stage) rocks of the Grünbach Formation, Austria. While it has traditionally been classified in the genus ''Ornithocheirus'', it is more likely an azhdarchid, though due to the fragmentary nature of known fossil remains, it is considered a ''nomen dubium In binomial nomenclature, a ''nomen dubium'' (Latin for "doubtful name", plural ''nomina dubia'') is a scientific name that is of unknown or doubtful application.
