Rhabdodontid
Rhabdodontidae is a family of herbivorous iguanodontian ornithopod dinosaurs whose earliest stem members appeared in the middle of the Lower Cretaceous. The oldest dated fossils of these stem members were found in the Barremian Castrillo de la Reina Formation of Spain, dating to approximately 129.4 to 125.0 million years ago. With their deep skulls and jaws, Rhabdodontids were similar to large, robust iguanodonts. The family was first proposed by David B. Weishampel and colleagues in 2003. Rhabdodontid fossils have been mainly found in Europe in formations dating to the Late Cretaceous. The defining characteristics of the clade Rhabdodontidae include the spade-shape of the teeth, the presence of three or more premaxillary teeth, the distinct difference between the two maxillary and dentary teeth ridge patterns, and the uniquely shaped femur, humerus, and ulna. Members of Rhabdodontidae have an adult body length of 1.6 to 6.0 meters. Description Teeth Rhabdodontids have a si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Matheronodon
''Matheronodon'' (meaning "Matheron tooth") is a genus of rhabdodontid ornithopod dinosaur from the late Cretaceous Period of the Grès à Reptiles Formation in France. The genus contains a single species, ''M. provincialis'', which is known from a single maxilla and associated teeth. It was named by Pascal Godefroit and colleagues in 2017. The teeth of ''Matheronodon'' are large but few in number. The teeth are also in an unusual arrangement, emerging alternatingly from one of a pair of fused tooth sockets in its mouth. In life, the teeth would have functioned like a pair of scissors, allowing ''Matheronodon'' to feed on the tough leaves of monocot plants. Description Like other rhabdodontids, ''Matheronodon'' would have been a bipedal herbivore. The length of the genus has been estimated at by its lead describer Pascal Godefroit. The maxilla of ''Matheronodon'' is a short, robust bone. The front portion is particularly shortened and also angled upwards, differentiating ''M ...

Zalmoxes
''Zalmoxes'' is an extinct genus of rhabdodontid ornithopod dinosaur from the Maastrichtian of Romania. The genus is known from specimens first named as the species '' Mochlodon robustum'' in 1899 by Franz Nopcsa before being reclassified as ''Rhabdodon robustum'' by him in 1915. In 1990 this name was corrected to ''Rhabdodon robustus'' by George Olshevsky, and in 2003 the species was once more reclassified, this time as the type species ''Zalmoxes robustus''. ''Zalmoxes'' refers to the Dacian deity Zalmoxis, and ''robustus'' to the robustness of the remains. In 2003 another species was named, ''Zalmoxes shqiperorum'', named for the Albanian name for Albanians. History of discovery ''Zalmoxes'' was first known from numerous fossils found in Transylvania, which were named as the species '' Mochlodon robustus'' by Baron Franz Nopcsa in 1899. The specific name referred to its robust build. In 1915 Nopcsa renamed the species as ''Rhabdodon robustum'', amended by in 2003 b ...

Mochlodon Vorosi
''Mochlodon'' is a genus of rhabdodontid dinosaurs from the Late Cretaceous of Austria and Hungary. It lived during the Late Cretaceous (85-80 Ma) and two species are known: ''M. suessi'' and ''M. vorosi''. Discovery and species In 1859 coal mine administrator Pawlowitsch notified the University of Vienna that some fossils had been found in the ''Gute Hoffnung'' mine at Muthmannsdorf in Austria. A team headed by geologists Eduard Suess and Ferdinand Stoliczka subsequently uncovered numerous bones of several species, among them those of a euornithopod dinosaur. Stored at the university museum, the finds remained undescribed until they were studied by Emanuel Bunzel from 1870 onwards. Bunzel in 1871 named the euornithopod a new species of ''Iguanodon'': ''Iguanodon suessii''. The specific name honours Suess and is today more often spelled ''suessi''. In 1881 Harry Govier Seeley named a separate genus: ''Mochlodon''. The generic name is derived from Greek ''mokhlos'', "bar", and ...

Transylvanosaurus
''Transylvanosaurus'' (meaning "lizard from across the forest") is an extinct genus of rhabdodontid ornithopod dinosaur from the Late Cretaceous (Maastrichtian) Hateg Basin of Romania. The type species is ''Transylvanosaurus platycephalus'', known from a fragmentary skull. Discovery and naming The holotype specimen, LPB (FGGUB) R.2070, was found in 2007 in the ‘Pui Beds’ in the Bărbat River Valley section of Haţeg Basin, Hunedoara County, Romania. This locality is dated to the middle Maastrichtian age of the Late Cretaceous period. It consists of a fragmentary skull, including the articulated basicranium and articulated frontals. In 2022, ''Transylvanosaurus platycephalus'' was described as a new genus and species of rhabdodontid ornithopod dinosaurs by Felix J. Augustin, Dylan Bastiaans, Mihai D. Dumbravă, and Zoltán Csiki-Sava based on these remains. The generic name, "''Transylvanosaurus''", is derived from the Latin words "trans", meaning "across" and "silva", mea ...

Pareisactus
''Pareisactus'' (from the Greek "pareisaktos", meaning "intruder", referring to being represented as a single element among hundreds of hadrosaurid bones) is a genus of rhabdodontid ornithopod dinosaur from the Late Cretaceous Conquès Member of the Tremp Formation in the Southern Pyrenees of Spain. The type and only species is ''P. evrostos'', known only from a single scapula The scapula (plural scapulae or scapulas), also known as the shoulder blade, is the bone that connects the humerus (upper arm bone) with the clavicle (collar bone). Like their connected bones, the scapulae are paired, with each scapula on eithe ....

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 it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tenontosaurus
''Tenontosaurus'' ( ; ) is a genus of medium- to large-sized ornithopod dinosaur. It was a relatively medium sized ornithopod, reaching in length and in body mass. It had an unusually long, broad tail, which like its back was stiffened with a network of bony tendons. The genus is known from the late Aptian to Albian ages of the Early Cretaceous period sediments of western North America, dating between 115 and 108 million years ago. It contains two species, ''Tenontosaurus tilletti'' (described by John Ostrom in 1970) and ''Tenontosaurus dossi'' (described by Winkler, Murry, and Jacobs in 1997). Many specimens of ''T. tilletti'' have been collected from several geological formations throughout western North America. ''T. dossi'' is known from only a handful of specimens collected from the Twin Mountains Formation of Parker County, Texas. History of discovery The first ''Tenontosaurus'' fossil was found in Big Horn County, Montana by an American Museum of Natural Histo ...
