Rhabdodon
''Rhabdodon'' (meaning "fluted tooth") is a genus of ornithopod dinosaur that lived in Europe approximately 70-66 million years ago in the Late Cretaceous. It is similar in build to a very robust " hypsilophodont" (non-iguanodont ornithopod), though all modern phylogenetic analyses find this to be an unnatural grouping, and ''Rhabdodon'' to be a basal member of Iguanodontia. It was large amongst its relatives, measuring long and weighing , with some specimens possibly reaching up to long. Discovery Two species of ''Rhabdodon'' are known, ''Rhabdodon priscus'', the type species, and ''R. septimanicus'' (Buffetaut and Le Loeuff, 1991). ''Rhabdodon'' remains are currently known from southern France, although fragmentary remains from eastern Spain have been assigned to the genus. ''Rhabdodon'' was large compared to its nearest relatives, and indeed one recent paper ( Ősi ''et al.'' (2012)) determined it is larger than the basal rhabdodontid status; from this they suggested that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ampelosaurus
''Ampelosaurus'' ( ; meaning "vine lizard") is a titanosaurian sauropod dinosaur from the Late Cretaceous Period of what is now France. Its type species is ''A. atacis'', named by Le Loeuff in 1995. A possible unnamed species has given ''Ampelosaurus'' an age reaching to the latest Cretaceous, from about 70 to 66 million years ago. Like most sauropods, it would have had a long neck and tail but it also carried armor in the form of osteoderms. Over 500 bones have been assigned to ''Ampelosaurus'' and all but the braincase (assigned to ''A.'' sp.) has been assigned to ''A. atacis''. They are assigned to the same species because all the differences in the limb proportions have been linked to individual variation. ''A. atacis'' is known from a few, well-preserved teeth and some cranial material. A right scapula was discovered associated with a coracoid. The blade of the scapula, contrary to most titanosaurs, is triangular. The blade narrows at one end instead of showing an expans ...

Iguanodontia
Iguanodontia (the iguanodonts) is a clade of herbivorous dinosaurs that lived from the Middle Jurassic to Late Cretaceous. Some members include ''Camptosaurus'', ''Dryosaurus'', ''Iguanodon'', '' Tenontosaurus'', and the hadrosaurids or "duck-billed dinosaurs". Iguanodontians were one of the first groups of dinosaurs to be found. They are among the best known of the dinosaurs, and were among the most diverse and widespread herbivorous dinosaur groups of the Cretaceous period. Classification Iguanodontia is often listed as an infraorder within a suborder Ornithopoda, though Benton (2004) lists Ornithopoda as an infraorder and does not rank Iguanodontia. Traditionally, iguanodontians were grouped into the superfamily Iguanodontoidea and family Iguanodontidae. However, phylogenetic studies show that the traditional "iguanodontids" are a paraphyletic grade leading up to the hadrosaurs (duck-billed dinosaurs). Groups like Iguanodontoidea are sometimes still used as unranked clades i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hypsilophodont
Hypsilophodontidae (or Hypsilophodontia) is a traditionally used family of ornithopod dinosaurs, generally considered invalid today. It historically included many small bodied bipedal neornithischian taxa from around the world, and spanning from the Middle Jurassic until the Late Cretaceous. This inclusive status was supported by some phylogenetic analyses from the 1990s and mid 2000s, although there have also been many finding that the family is an unnatural grouping which should only include the type genus, ''Hypsilophodon'', with the other genera being within clades like Thescelosauridae and Elasmaria. A 2014 analysis by Norman recovered a grouping of ''Hypsilophodon'', Rhabdodontidae and ''Tenontosaurus'', which he referred to as Hypsilophodontia. All other analyses from around the same time have instead found these latter taxa to be within Iguanodontia. Linnaean usage Hypsilophodontidae was named originally in 1882 by Louis Dollo, as a family to include ''Hypsilophodon' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Éric Buffetaut
Éric Buffetaut (born 19 November 1950) is a French paleontologist, author and researcher at the Centre national de la recherche scientifique since 1976 where he is a Doctor of Science and Director of Research. Buffetaut is a specialist of fossil archosaurs, mainly dinosaurs and pterosaurs, and has published many books on paleontology. He is one of the major paleontologists to support the thesis of the fall of a meteorite as the main cause of the Cretaceous–Paleogene extinction event. Notable works Buffetaut named and described the following species: * '' Archaeodontosaurus descouensi'' * '' Euthecodon arambourgi'' * '' Isanosaurus attavipachi'' * '' Isalorhynchus genovefae'' * '' Kinnareemimus khonkaenensis'' * ''Normannognathus wellnhoferi'' * '' Phuwiangosaurus sirindhornae'' * '' Psittacosaurus sattayaraki'' * '' Rhabdodon septimanicus'' * '' Siamamia naga'' * '' Siamosaurus suteethorni'' * '' Siamotyrannus isanensis'' * '' Tarascosaurus salluvicus'' * '' Tilemsisuchus lav ...

Ornithopod
Ornithopoda () is a clade of ornithischian dinosaurs, called ornithopods (), that started out as small, bipedal running grazers and grew in size and numbers until they became one of the most successful groups of herbivores in the Cretaceous world, dominating the North American land. Their major evolutionary advantage was the progressive development of a chewing apparatus that became the most sophisticated ever developed by a non-avian dinosaur, rivaling that of modern mammals such as the domestic cow. They reached their apex of diversity and ecological dominance in the hadrosaurids (colloquially known as 'duck-bills'), before they were wiped out by the Cretaceous–Paleogene extinction event along with all other non- avian dinosaurs. Members are known from all seven continents, though they are generally rare in the Southern Hemisphere. History of research In 1870, Thomas Henry Huxley listed Iguanodontidae (coined by Cope a year earlier) as one of his three families of dinos ...

Dinosaur
Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago (mya), although the exact origin and timing of the evolution of dinosaurs is the subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201.3 mya; their dominance continued throughout the Jurassic and Cretaceous periods. The fossil record shows that birds are feathered dinosaurs, having evolved from earlier theropods during the Late Jurassic epoch, and are the only dinosaur lineage known to have survived the Cretaceous–Paleogene extinction event approximately 66 mya. Dinosaurs can therefore be divided into avian dinosaurs—birds—and the extinct non-avian dinosaurs, which are all dinosaurs other than birds. Dinosaurs are varied from taxonomic, morphological and ecological standpoints. Birds, at over 10,700 living species, ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
