Kinnareemimus
''Kinnareemimus'' (, meaning "Kinnara#Thailand, Kinnaree mimic", after a figure from Thai folklore) is an extinct genus of ornithomimosaurian theropod dinosaur that was discovered in the Early Cretaceous Sao Khua Formation in what is now Thailand. The genus contains only the type species, ''K. khonkaenensis''. The specific epithet is after Khon Kaen Province, which is in northeastern Thailand, where the remains of the animal were discovered. Discovery and naming Ornithomimosaur body fossils and ichnofossils were reported in Thailand's Khorat Plateau as early as 1997 in a publication by Eric Buffetaut and colleagues. At the time, only two dinosaur genera, ''Siamotyrannus'' and ''Phuwiangosaurus'' had been named from the country. Their report included a drawing of the metatarsals of an ornithomimosaur which had been uncovered at a locality called "Phu Wiang 5". These metatarsals clearly showed the derived arctometatasalian condition, similar to the ornithomimosaurs known from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aggiosaurus
''Aggiosaurus'' is an extinct genus of geosaurine metriorhynchid crocodyliform known from the Late Jurassic (late Oxfordian stage) of Nice, southeastern France. It contains a single species, ''Aggiosaurus nicaeensis'', which was named by H. Ambayrac in 1913.H. Ambayrac. (1913).

Dakosaurus
''Dakosaurus'' is an extinct genus of crocodylomorph within the family Metriorhynchidae that lived during the Late Jurassic and Early Cretaceous. It was large, with teeth that were serrated and compressed lateromedially (flattened from side to side). The genus was established by Friedrich August von Quenstedt in 1856 for an isolated tooth named ''Geosaurus maximus'' by Theodor Plieninger in 1846. ''Dakosaurus'' was a carnivore that spent much, if not all, of its life out at sea. The extent of its adaptation to a marine lifestyle means that it is most likely that it mated at sea, but since no eggs or nests have been discovered that have been referred to ''Dakosaurus'', whether it gave birth to live young at sea like dolphins and ichthyosaurs or came ashore like turtles is not known yet. The name ''Dakosaurus'' means "biter lizard", and is derived from the Greek ' ("biter") and -' ("lizard"). Discovery and species The type species ''Dakosaurus maximus'', meaning "greatest ...

Variraptor
''Variraptor'' ( ; "Var thief") is a possibly dubious and potentially chimaeric genus of dromaeosaurid theropod dinosaur from the Late Cretaceous of France. Discovery Between 1992 and 1995 amateur paleontologists Patrick Méchin and Annie Méchin-Salessy uncovered the remains of a small theropod in the Grès à Reptiles Formation (Campanian-Maastrichtian) at La Bastide Neuve, near Fox-Amphoux. The first finds were in 1992 assigned to the theropod genus '' Elopteryx''. A second article, in 1997, concluded they represented a new species. In 1998 this was named by Jean Le Loeuff and Eric Buffetaut as the type species ''Variraptor mechinorum''. The generic name is derived from Latin ''Varus'', referring to the Var River in the Alpes-Maritimes department in the Provence region of southern France, and ''raptor'' meaning "thief". The specific name honours the Méchin couple. The genus is based on three type specimens: a posterior dorsal vertebra (MDE-D168), a sacrum (MDE-D169 ...

Trematochampsa
''Trematochampsa'' is a dubious extinct genus of crocodyliform from the Late Cretaceous (Coniacian-Santonian age) In Beceten Formation of Niger. Taxonomy The type species, ''T. taqueti'', was described by Eric Buffetaut in 1974. A second species, ''T. oblita'', was named from Madagascar in 1979, but was renamed '' Miadanasuchus'' in 2009. ''Trematochampsa'' gives its name to the Trematochampsidae, a poorly known group of fossil crocodiles. However, the labile phylogenetic position of ''Trematochampsa'' in many studies has been attributed to character conflict, leading many authors to exclude this genus from many cladistic analyses, but Sertich et al. (2014) noted that the referred material of ''Trematochampsa'' consists of more than one crocodyliform taxon, so they opted to use only the cranial material in the dataset for the cladistic analysis of '' Rukwasuchus'' and recommended removing the postcranial material from ''Trematochampsa''. The analysis recovered ''Trematochampsa' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tilemsisuchus
''Tilemsisuchus'' is an extinct genus of dyrosaurid crocodyliform which existed in what is now Mali during the Eocene period. It was first named by Eric Buffetaut in 1979 and contains the species ''Tilemsisuchus lavocati''.''Wounds on the jaw of an Eocene mesosuchian crocodilian as possible evidence for the antiquity of crocodilian intraspecific fighting behaviour'', by Eric Buffetaut, Laboratoire de Paléontologie des Vertébrés, Université Paris VI, 4 place Jussieu, 75230 Paris Cedex 05, France References External links ''Tilemsisuchus''at the Paleobiology Database The Paleobiology Database (PBDB) is an online resource for information on the distribution and classification of fossil animals, plants, and microorganisms.

Tarascosaurus
''Tarascosaurus'' ("Tarasque lizard") is a genus of abelisaurid theropod dinosaur from Late Cretaceous of France. It was a relatively small theropod measuring long. Discovery After having in 1988 identified an upper jaw bone found near Pourcieux as belonging to a member of the Abelisauridae, French paleontologist Éric Buffetaut reviewed the known remains of larger theropods found in the Late Cretaceous of Europe concluding they all were of abelisaurid affinity. Most of these fossils, earlier named as ''Megalosaurus pannoniensis'', ''Megalosaurus hungaricus'' and ''Megalosaurus lonzeensis'', he considered to be ''nomina dubia'' because of the paucity of the material. However, when in the collection of the University of Lyon he discovered some theropod bones once excavated by an unknown collector at an escarpment of a place named ''Lambeau du Beausset'', in the "syncline of Le Beausset" (in French: ''synclinal du Beausset''), Buffetaut and Jean Le Loeuff named and described th ...

Siamotyrannus
''Siamotyrannus'' (meaning "Siamese tyrant") is a genus of theropod dinosaur from the early Cretaceous of Thailand. Discovery and naming In 1993, Somchai Traimwichanon found a partial skeleton of a large theropod at the Phu Wiang 9 site in Khon Kaen. In 1996, Eric Buffetaut, Varavudh Suteethorn and Haiyan Tong named and described the type species ''Siamotyrannus isanensis''. The generic name is derived from the old Thai kingdom of Siam, and a Latinised Greek ''tyrannus'', meaning "tyrant", in reference to a presumed membership of the Tyrannosauridae. The specific name is derived from Thai ''isan'', "northeastern part", referring to the provenance from northeast Thailand. The holotype, PW9-1, was found in the Sao Khua Formation, dating from the Berriasian-Barremian. It includes the left half of the pelvis, five rear dorsal vertebrae, the sacrum with five sacrals, and thirteen front tail vertebrae. In 1998, a tibia and some individual teeth were referred to the species. Descri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siamosaurus
''Siamosaurus'' (meaning "Siam lizard") is a potentially nomen dubium, dubious genus of Spinosauridae, spinosaurid dinosaur that lived in what is now known as China and Thailand during the Early Cretaceous Period (geologic time), period (Barremian to Aptian) and is the first reported spinosaurid from Asia. It is confidently known only from tooth fossils; the first were found in the Sao Khua Formation, with more teeth later recovered from the younger Khok Kruat Formation. The Monotypic taxon, only species ''Siamosaurus suteethorni'', whose name honours Thai palaeontologist Varavudh Suteethorn, was formally described 1986 in paleontology, in 1986. In 2009, four teeth from China previously attributed to a Pliosauroidea, pliosaur—under the species "''Sinopliosaurus''" ''fusuiensis''—were identified as those of a spinosaurid, possibly ''Siamosaurus''. It is yet to be determined if two partial spinosaurid skeletons from Thailand and an isolated tooth from Japan also belong to ''S ...

Obelignathus
''Obelignathus'' (meaning "Obelix jaw") is an extinct genus of rhabdodontomorph ornithopod dinosaurs from the Late Cretaceous 'Grès à Reptiles' Formation of France. The genus contains a single species, ''O. septimanicus'', known from a right dentary. The species was initially classified as a species of the coeval '' Rhabdodon''. Discovery and naming The ''Obelignathus'' holotype specimen, MDE D30, was discovered in 1990 in outcrops of the 'Grès à Reptiles' Formation near Montouliers in Saint-Chinian commune of Hérault, southern France. The specimen consists of an isolated right dentary, missing the anterior (front) part. The specimen was first described in 1991 by Éric Buffetaut and Jean Le Loeuff. Based on the general morphology and dental anatomy, they identified it as belonging to the genus '' Rhabdodon'', named as a hypsilophodont in 1869. However, they described it as a new species, ''R. septimanicus'' due to other differing anatomical characteristics. The spe ...
