Attenborosaurus
''Attenborosaurus'' is an extinct genus of pliosaurid from the Early Jurassic of Dorset, England. The type species is ''A. conybeari''. The genus is named after David Attenborough, the species after William Conybeare. History The original remains of the holotype, specimen PV OR 38525, were discovered in Charmouth, Dorset, England in 1880 and was described in 1881 before being housed at the Bristol City Museum and Art Gallery, where a cast was taken of NHMUK R1339 and sent to the Natural History Museum in London by William Johnson Sollas, , where it stayed until the holotype was destroyed in November 1940, during World War II, leaving only plaster casts of the remains to be studied; the type cast (specimen NHMUK R1339) is now housed at the Natural History Museum, London along with a referred specimen (specimen NHMUK OR40140/R1360; includes no head, neck or tail, most of the body, ribs and all flippers except for the front right) and another partial specimen, including a skull a ...

Pliosauridae
Pliosauridae is a family of plesiosaurian marine reptiles from the Latest Triassic to the early Late Cretaceous ( Rhaetian to Turonian stages) of Australia, Europe, North America and South America. The family is more inclusive than the archetypal short-necked large headed species that are placed in the subclade Thalassophonea, with basal forms resembling other plesiosaurs with long necks. They became extinct during the early Late Cretaceous and were subsequently replaced by the mosasaurs. It was formally named by Harry G. Seeley in 1874. Relationships Pliosauridae is a stem-based taxon defined in 2010 (and in earlier studies in a similar manner) as "all taxa more closely related to ''Pliosaurus brachydeirus'' than to '' Leptocleidus superstes'', '' Polycotylus latipinnis'' or ''Meyerasaurus victor''". The family Brachauchenidae has been proposed to include pliosauroids which have very short necks and may include ''Brachauchenius'' and ''Kronosaurus''. However, modern cladisti ...

Plesiosauria
The Plesiosauria (; Greek: πλησίος, ''plesios'', meaning "near to" and ''sauros'', meaning "lizard") or plesiosaurs are an order or clade of extinct Mesozoic marine reptiles, belonging to the Sauropterygia. Plesiosaurs first appeared in the latest Triassic Period, possibly in the Rhaetian stage, about 203 million years ago. They became especially common during the Jurassic Period, thriving until their disappearance due to the Cretaceous–Paleogene extinction event at the end of the Cretaceous Period, about 66 million years ago. They had a worldwide oceanic distribution, and some species at least partly inhabited freshwater environments. Plesiosaurs were among the first fossil reptiles discovered. In the beginning of the nineteenth century, scientists realised how distinctive their build was and they were named as a separate order in 1835. The first plesiosaurian genus, the eponymous ''Plesiosaurus'', was named in 1821. Since then, more than a hundred vali ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thalassophonea
Thalassophonea is an extinct clade of pliosaurids from the Middle Jurassic to the early Late Cretaceous (Callovian to Turonian) of Australia, Europe, North America and South America. ''Thalassophonea'' was erected by Roger Benson and Patrick Druckenmiller in 2013. The name is derived from Greek ''thalassa'' (θάλασσα), "sea", and ''phoneus'' (φονεύς), "murderer". It is a stem-based taxon defined as "all taxa more closely related to ''Pliosaurus brachydeirus'' than to ''Marmornectes candrewi''". It includes the short necked and large headed taxa that typify the family. Classification The following cladogram A cladogram (from Greek ''clados'' "branch" and ''gramma'' "character") is a diagram used in cladistics to show relations among organisms.

Hauffiosaurus
''Hauffiosaurus'' is an extinct genus of Early Jurassic (early Toarcian stage) pliosaurid plesiosaur known from Holzmaden of Germany and from Yorkshire of the United Kingdom. It was first named by Frank Robin O’Keefe in 2001 and the type species is ''Hauffiosaurus zanoni''. In 2011, two additional species were assigned to this genus: ''H. longirostris'' and ''H. tomistomimus''. Description The holotype specimen of ''Hauffiosaurus'', housed in the Hauff Museum, is an almost complete and articulated skeleton, found from the Posidonien-Schiefer, dating to early Toarcian stage of the Early Jurassic. The holotype specimen preserved in a single block of the original matrix, exposed in ventral view. The body outline visible around the specimen is an artifact of preparation, not preservation; no remains of soft tissue were preserved. The skeleton was discovered during the early 19th Century, in beds of the famous Posidonien-Schiefer lagerstätte at Holzmaden, Baden-Württemberg, in ...

Over his life he has collected dozens of honorary degrees and awards, including 3 Emmy Awards for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Simolestes
''Simolestes'' (meaning "hearkening thief") is an extinct pliosaurid genus that lived in the Middle to Late Jurassic. The type specimen, BMNH R. 3319 is an almost complete but crushed skeleton diagnostic to ''Simolestes vorax'', dating back to the Callovian of the Oxford Clay formation, England. The genus is also known from the Callovian and Bajocian of France (''S.keileni''), and the Tithonian of India (''S.indicus''). The referral of these two species to ''Simolestes'' is dubious, however. Description ''Simolestes'' possessed a short, high, and wide skull which was built to resist torsional forces when hunting. The largest specimens of ''S.vorax'' reached approximately in length, if a head to body ratio similar to ''Liopleurodon'' is applied. ''S.keileni'' was larger, with specimens from France suggesting that some individuals grew more than long. ''S. vorax'' and ''S. keileni'' weighed about , respectively. Palaeobiology Like most Pliosaurs, ''Simolestes'' possessed sal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thalassiodracon
''Thalassiodracon'' (tha-LAS-ee-o-DRAY-kon) is an extinct genus of plesiosauroid from the Pliosauridae that was alive during the Late Triassic-Early Jurassic (Rhaetian-Hettangian) and is known exclusively from the Lower Lias of England. The type and only species, is ''Thalassiodracon'' (''Plesiosaurus'') ''hawkinsi'' (Owen, 1838). Owen, R. (1838). A description of Viscount Cole's specimen of '' Plesiosaurus macrocephalus'' ( Conybeare). ''Proceedings of the Geological Society of London 2'', 663-666. Discovery and naming ''Thalassiodracon hawkinsi'' is known from a number of complete skeletons (lectotype: BMNH 2018) acquired by the fossil collector Thomas Hawkins in Somerset, England during the early 1830s, before 1834. Hawkins, an eccentric Pre-Adamite who had his fossils heavily restaured and illustrated by distinguished artists in expensive editions to propagate his ideas, named these ''Plesiosaurus triotarsostinus'' in 1834 and ''Hezatarostinus'' in 1840 but these names are ...

Plesiosaurus
''Plesiosaurus'' (Greek: ' ('), near to + ' ('), lizard) is a genus of extinct, large marine sauropterygian reptile that lived during the Early Jurassic. It is known by nearly complete skeletons from the Lias Group, Lias of England. It is distinguishable by its small head, long and slender neck, broad turtle-like body, a short tail, and two pairs of large, elongated paddles. It lends its name to the order Plesiosauria, of which it is an early, but fairly typical member. It contains only one species, the type species, type, ''Plesiosaurus dolichodeirus''. Other species once assigned to this genus, including ''P. brachypterygius'', ''P. guilielmiimperatoris'', and ''P. tournemirensis'' have been reassigned to new genera, such as ''Hydrorion'', ''Seeleyosaurus'' and ''Occitanosaurus''. Discovery The first complete skeleton of ''Plesiosaurus'' was discovered by early paleontologist and fossil hunter Mary Anning in Sinemurian (Early Jurassic)-age rocks of the lower Lias Group in Dec ...

Marmornectes
''Marmornectes'' is a genus of pliosaurid known from the Middle Jurassic of Bedfordshire, United Kingdom. Description ''Marmornectes'' is known from the holotype BEDFM 1999.201, an articulated partial skeleton which includes the skull. It was collected in 1999 from the ''Sigaloceras enodatum'' ammonoid subzone of the Peterborough Member, Oxford Clay Formation, which dates to the early Callovian stage of the late Middle Jurassic, about 164.7-163.5 million years ago. It was found in the monotypic locality of Quest Pit, east of Stewartby. It was a longirostrine pliosaurid with seven autapomorphies, and is most similar to ''Peloneustes philarchus''. Nevertheless, a cladistic analysis found it to be basal to ''Peloneustes'' and other pliosaurids. An undescribed pliosaurid, NHMUK R2439, was found to be the sister taxon of this genus. Etymology ''Marmornectes'' was first named by Hilary F. Ketchum and Roger B. J. Benson in 2011 and the type species is ''Marmornectes can ...
