Dinosaurs * On June 30, Sir Richard Owen presents his findings regarding some enormous bones that the Reverend William Buckland had acquired at an earlier date. He names the new genus to which these bones belong "''Cetiosaurus''." This event marks the first scientific description of a sauropod. * Owen presents his treatise on British fossil reptiles to the British Association in August. This treatise marks the creation of a taxon called "Dinosauria."

Cetiosaurus
''Cetiosaurus'' () meaning 'whale lizard', from the Greek '/ meaning 'sea monster' (later, 'whale') and '/ meaning 'lizard', is a genus of herbivorous sauropod dinosaur from the Middle Jurassic Period, living about 168 million years ago in what is now Europe. ''Cetiosaurus'' was in 1842 the first sauropod from which bones were described and is the most complete sauropod found in England. It was so named because its describer, Sir Richard Owen, supposed it was a marine creature, initially an extremely large crocodile, and did not recognise it for a land-dwelling dinosaur. Because of the early description many species would be named in the genus, eventually eighteen of them. Most of these have now been placed in other genera or are understood to be dubious names, based on poor fossil material. The last is true also of the original type species, ''Cetiosaurus medius'', and so ''C. oxoniensis'' was officially made the new type species in 2014. ''C. oxoniensis'' is based on three mor ...

Pliosaurus Rossicus
''Pliosaurus'' (meaning 'more lizard') is an extinct genus of thalassophonean pliosaurid known from the Kimmeridgian and Tithonian stages (Late Jurassic) of Europe and South America. Their diet would have included fish, cephalopods, and marine reptiles. This genus has contained many species in the past but recent reviews found only six (''P. brachydeirus'', ''P. carpenteri'', ''P. funkei'', ''P. kevani'', ''P. rossicus'' and ''P. westburyensis'') to be valid, while the validity of two additional species awaits a petition to the International Code of Zoological Nomenclature. Currently, ''P. brachyspondylus'' and ''P. macromerus'' are considered dubious, while ''P. portentificus'' is considered undiagnostic. Most species of ''Pliosaurus'' reached in length and in body mass, while ''P. rossicus'' and ''P. funkei'' may have reached or even exceeded in length and in body mass, being the largest plesiosaurs of all time. Species of this genus are differentiated from other pliosaur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abydosaurus
''Abydosaurus'' (meaning "Abydos lizard") is a genus of brachiosaurid sauropod dinosaur known from skull and postcranial material found in upper Lower Cretaceous rocks of northeastern Utah, United States. Discovery ''Abydosaurus'' is one of the few sauropods known from skull material, with the first described complete skull for a Cretaceous sauropod from the Americas. It is also notable for its narrow teeth, as earlier brachiosaurids had broader teeth. ''Abydosaurus'' is based on the holotype DINO 16488, a nearly complete skull and lower jaws with the first four neck vertebrae. Abundant skull and postcranial bones were found at the same site, including partial skulls from three additional individuals, a partial hip and associated tail vertebrae, a shoulder blade, an upper arm bone, and hand bones. These fossils were found in a sandstone bed at the base of the Mussentuchit Member of the Cedar Mountain Formation, near the old visitor center of Dinosaur National Monument. ...

19xx In Paleontology
The 20th (twentieth) century began on January 1, 1901 ( MCMI), and ended on December 31, 2000 ( MM). The 20th century was dominated by significant events that defined the modern era: Spanish flu pandemic, World War I and World War II, nuclear weapons, nuclear power and space exploration, nationalism and decolonization, technological advances, and the Cold War and post-Cold War conflicts. These reshaped the political and social structure of the globe. The 20th century saw a massive transformation of humanity's relationship with the natural world. Global population, sea level rise, and ecological collapses increased while competition for land and dwindling resources accelerated deforestation, water depletion, and the mass extinction of many of the world's species and decline in the population of others. Global heating increased the risk of extreme weather conditions. Additional themes include intergovernmental organizations and cultural homogenization through developments i ...

Rhopalodon
''Rhopalodon'' is an extinct genus of therapsids from the Permian of Russia. It has been variously classified as a dinosaur, a dinocephalian, or another branch of Reptilia. ''Rhopalodon'' is notable for being among the first reptiles mentioned in ''Nature''. T.H. Huxley wrote of this reptile, among others, in the inaugural issue of the magazine, in November 1869. He gave the age of this animal and of the contemporary ''Deuterosaurus'' as Triassic, but both are now known to have lived during the Middle Permian. According to Tverdokhlebov ''et al.'' (2005), ''Rhopalodon'' was a medium-sized terrestrial dinocephalian herbivore that was characteristic of the early Tatarian Urzhumian biostratigraphic zone (Bolshekinelskaya and Amanakskaya svitas).

Thaumatosaurus
''Rhomaleosaurus'' (meaning "strong lizard") is an extinct genus of Early Jurassic (Toarcian age, about 183 to 175.6 million years ago) rhomaleosaurid pliosauroid known from Northamptonshire and from Yorkshire of the United Kingdom. It was first named by Harry Seeley in 1874 and the type species is ''Rhomaleosaurus cramptoni''. It was one of the earliest large marine reptile predators which hunted in the seas of Mesozoic era, with the type species ''R. cramptoni'' measuring long and weighing . Like other pliosaurs, ''Rhomaleosaurus'' fed on ichthyosaurs, ammonites and other plesiosaurs. Species ''R. cramptoni'' In July 1848, a fossil of a large plesiosaur was unearthed in an Alum quarry at Kettleness, near Whitby, in Yorkshire, England. It was collected from the ''A. bifrons'' ammonite zone of the Whitby Mudstone Formation, dating to the early Toarcian age, about 183 to 180 million years ago. The complete skeleton which preserved the skull, NMING F8785, was kept f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyptychodon
''Polyptychodon'' (meaning 'shaped fin tooth') is a genus of pliosaurid found in Middle-Late Cretaceous marine deposits in southern England, France and Argentina. It has been considered a '' nomen dubium'' in a 2016 review. History of discovery The type species, ''P. interruptus'' is known from an isolated tooth from the Late Cretaceous Chalk Group of southern England. Owen described a second nominal species of the genus, ''P. continuus'', from an isolated tooth collected in the Hythe Formation of Maidstone, Kent. (The macronarian sauropod '' Dinodocus'' was mistakenly thought to be conspecific with ''P. continuus'' before it was correctly recognized as a dinosaur and not a plesiosaur.) Numerous pliosaurid teeth and vertebrae from England and eastern France have been previously assigned to ''Polyptychodon'', including isolated vertebrae from France which were misidentified as a sauropod.

Pliosauroidea
Pliosauroidea is an extinct clade of plesiosaurs, known from the earliest Jurassic to early Late Cretaceous. They are best known for the subclade Thalassophonea, which contained crocodile-like short-necked forms with large heads and massive toothed jaws, commonly known as pliosaurs. More primitive non-thalassophonean pliosauroids resembled pleisiosaurs in possessing relatively long necks and smaller heads. They originally included only members of the family Pliosauridae, of the order Plesiosauria, but several other genera and families are now also included, the number and details of which vary according to the classification used. The distinguishing characteristics are a short neck and an elongated head, with larger hind flippers compared to the fore flippers, the opposite of the plesiosaurs. They were carnivorous and their long and powerful jaws carried many sharp, conical teeth. Pliosaurs range from 4 to 15 metres and more in length. Their prey may have included fish, shar ...

Cardiodon
''Cardiodon'' (meaning "heart tooth", in reference to the shape) was a herbivorous genus of sauropod dinosaur, based on a tooth from the late Bathonian-age Middle Jurassic Forest Marble Formation of Wiltshire, England. Historically, it is very obscure and usually referred to '' Cetiosaurus'', but recent analyses suggest that it is a distinct genus, and possibly related to '' Turiasaurus''. ''Cardiodon'' was the first sauropod genus named.Taylor, Michael P., 2010, "Sauropod dinosaur research: a historical review", pp. 361-386 in: Richard T. J. Moody, Eric Buffetaut, Darren Naish and David M. Martill (eds.), ''Dinosaurs and Other Extinct Saurians: a Historical Perspective''. Geological Society of London, Special Publication 343 History and taxonomy Richard Owen named the genus for a now-lost tooth, part of the collection of naturalist Joseph Chaning Pearce, found near Bradford-on-Avon, but did not assign it a specific name at the time.

Baryonyx
''Baryonyx'' () is a genus of theropod dinosaur which lived in the Barremian stage of the Early Cretaceous period, about 130–125 million years ago. The first skeleton was discovered in 1983 in the Smokejack Clay Pit, of Surrey, England, in sediments of the Weald Clay Formation, and became the holotype specimen of ''Baryonyx walkeri'', named by palaeontologists Alan J. Charig and Angela C. Milner in 1986. The generic name, ''Baryonyx'', means "heavy claw" and alludes to the animal's very large claw on the first finger; the specific name, ''walkeri'', refers to its discoverer, amateur fossil collector William J. Walker. The holotype specimen is one of the most complete theropod skeletons from the UK (and remains the most complete Spinosaurid), and its discovery attracted media attention. Specimens later discovered in other parts of the United Kingdom and Iberia have also been assigned to the genus, though many have since been moved to new genera. The holotype specimen, which ...
