Lambeosaur
Lambeosauridae /ˌlæmbiəˈsɔːraɪniː/ (meaning 'lambe's lizards') is an extinct group of crested hadrosauroid dinosaurs. Description Size Uncertainty surrounds the size of lambeosaurs from the European continent. Hadrosaurs found there, alongside other dinosaurs, have traditionally been considered representatives of the phenomenon of insular dwarfism, as the continent was then made up of many smaller islands. Many fossil remains from the continent are smaller than those of hadrosaurs found elsewhere in the world, with only isolated remains indicating individuals of adult size by the standards of their relatives in North America and Asia. It remains possible, however, that at least some cases instead represent misidentification of juvenile remains.Dalla Vecchia, F. M. (2014).

Lambeosaurus
''Lambeosaurus'' ( ) is a genus of hadrosaurid dinosaur that lived during the Late Cretaceous period of western North America. The first skull of ''Lambeosaurus'' found was used by palaeontologist Lawrence M. Lambe to justify the creation of the new genus '' Stephanosaurus'', though it was not part of the original ''Stephanosaurus'' material. The incomplete nature of the original ''Stephanosaurus'' material led William A. Parks to name ''Lambeosaurus lambei'' for this skull in 1923 to honour Lambe. Multiple further species of ''Lambeosaurus'' have been named since, including ''L. clavinitialis'' and ''L. magnicristatus'' in 1935, and ''L. laticaudus'' in 1981 which was later moved to its own genus '' Magnapaulia''. It has also been identified that some species earlier identified as belonging to ''Tetragonosaurus'' and ''Corythosaurus'' are now considered juveniles of ''Lambeosaurus''. ''Lambeosaurus'' is the eponymous member of its subfamily Lambeosaurinae and tribe Lambeos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pararhabdodon
''Pararhabdodon'' (meaning "near fluted tooth" in reference to ''Rhabdodon'') is a genus of tsintaosaurin hadrosaurid dinosaur, from the Maastrichtian-age Upper Cretaceous Tremp Group of Spain. The first remains were discovered from the Sant Romà d’Abella fossil locality and assigned to the genus ''Rhabdodon'', and later named as the distinct species ''Pararhabdodon isonensis'' in 1993. Known material includes assorted postcranial remains, mostly vertebrae, as well as from the skull. Specimens from other sites, including remains from France, a maxilla previously considered the distinct taxon ''Koutalisaurus kohlerorum'', an additional maxilla from another locality, the material assigned to the genera ''Blasisaurus'' and ''Arenysaurus'', and the extensive Basturs Poble bonebed have been considered at different times to belong to the species, but all of these assignments have more recently been questioned. It was one of the last non-avian dinosaurs known from the fossil record th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canardia
''Canardia'' is an extinct genus of lambeosaurine dinosaur known from the Late Cretaceous Marnes d'Auzas Formation (late Maastrichtian stage) of Haute-Garonne Departments of France, department, in Occitania (administrative region), Occitanie Regions of France, region, southwestern France. The type species ''Canardia garonnensis'' was first described and named by Albert Prieto-Márquez, Fabio M. Dalla Vecchia, Rodrigo Gaete and Àngel Galobart in 2013 in paleontology, 2013. It is only known from juvenile specimens. The name of the genus comes from “canard”, the French word for “duck”, an allusion to the fact that this animal belongs to the hadrosaurids which are also known as duck-billed dinosaurs. The Specific name (zoology), specific epithet ''garonnensis'' refers to the Haute-Garonne department where this dinosaur has been found. Although universally recognized as a lambeosaurine, its precise position within them is debated. Some authors consider it as a close relative of ...

Parasaurolophus Cyrtocristatus
''Parasaurolophus'' (; meaning "beside crested lizard" in reference to ''Saurolophus'') is a genus of Hadrosauridae, hadrosaurid "duck-billed" dinosaur that lived in what is now Laramidia, western North America and possibly Asia during the Late Cretaceous Period (geology), period, about 76.9–73.5 million years ago. It was a large herbivore that could reach over long and weigh over , and were able to move as a bipedalism, biped and a quadruped. Three species are universally recognized: ''P. walkeri'' (the type species), ''P. tubicen'', and the short-crested ''P. cyrtocristatus''. Additionally, a fourth species, ''P. jiayinensis'', has been proposed, although it is more commonly placed in the separate genus ''Charonosaurus''. Remains are known from Alberta, New Mexico, and Utah, as well as possibly Heilongjiang if ''Charonosaurus'' is in fact part of the genus. The genus was first described in 1922 by William Parks (paleontologist), William Parks from a sk ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adelolophus
''Adelolophus'' (meaning "unknown crest") is a genus of lambeosaurinae, lambeosaurine dinosaur (a crested "hadrosaurid, duck-bill") from Upper Cretaceous rocks in the U.S. state of Utah. The type species, type and only known species is ''A. hutchisoni''; the type specimen consists only of a broken . It constitutes the oldest known lambeosaur remains from North America, as well as the only known lambeosaur species from the Wahweap Formation, of which it pertains to the Upper Member. Among its relatives, it seems to be particularly similar to ''Parasaurolophus'', rather than animals like ''Lambeosaurus''; phylogenetic analysis confirms this, finding it in Parasaurolophini (tube-headed lambeosaurs). It would have lived in a wet environment, bordering on the sea but with a more arid season during some times of the year. This environment would have been shared with a diverse variety of fish and turtles, as well as other dinosaurs like ceratopsids and tyrannosaurids. Discovery and nami ...

Corythosaurus
''Corythosaurus'' (; ) is a genus of hadrosaurid "duck-billed" dinosaur from the Late Cretaceous Period (geology), period, about 77–75.7 million years ago, in what is now Laramidia, western North America. Its name is derived from the Ancient Greek, Greek word κόρυς, meaning "helmet", named and described in 1914 by Barnum Brown. ''Corythosaurus'' is now thought to be a Lambeosaurinae, lambeosaurine, thus related to ''Lambeosaurus'', ''Nipponosaurus'', ''Velafrons'', ''Hypacrosaurus'', and ''Olorotitan''. ''Corythosaurus'' has an estimated length of and has a skull, including the crest, that is tall. ''Corythosaurus'' is known from many complete specimens, including the nearly complete holotype found by Brown in 1911. The holotype skeleton is only missing the last section of the tail and part of the front legs, but was preserved with impressions of polygonal scales. ''Corythosaurus'' is known from many skulls with tall crests that resemble those of the cassowary and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adynomosaurus
''Adynomosaurus'' is a genus of lambeosaurine dinosaur from the Late Cretaceous of what is now Catalonia, Spain. First discovered in 2012, it was named in 2019 with the type species, type and only species being ''Adynomosaurus arcanus''. It is only known from scant material, but is distinguished from other hadrosaurs by its weakly developed shoulder blade which would have had underdeveloped musculature, which lends it its scientific name, partially from the Greek word for "weak". Its exact relationships with other hadrosaurs remain unresolved, with it not consistently being recovered as a relative of any other specific genera, though some studies have allied it with Tsintaosaurini or even found it outside of Hadrosauridae. It would have lived as part of a diverse coastal estuary ecosystem, made up of meandering rivers and mud flats. The discovery of ''Adynomosaurus'' adds to the very incomplete fossil record of hadrosaurid dinosaurs in the Late Cretaceous of Europe, and it fits int ...

Hypacrosaurus
''Hypacrosaurus'' (meaning "near the highest lizard" [Greek υπο-, ''hypo-'' = less + ακρος, ''akros'', high], because it was almost but not quite as large as ''Tyrannosaurus'') is an extinct genus of hadrosaurid, duckbill dinosaur similar in appearance to ''Corythosaurus''. Like ''Corythosaurus'', it had a tall, hollow rounded crest, although not as large and straight. It is known from the remains of two species that spanned 75 to 67 million years ago, in the Late Cretaceous of Alberta, Canada, and Montana, United States, and is the latest hollow-crested duckbill known from good remains in North America. It was an obscure genus until the discovery in the 1990s of nests, egg (biology), eggs, and hatchlings belonging to ''H. stebingeri''. Discovery and history The holotype, type remains of ''Hypacrosaurus'' were collected in 1910 by Barnum Brown for the American Museum of Natural History. The remains, a partial postcranial skeleton consisting of several vertebrae and a par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olorotitan
''Olorotitan'' was a monotypic genus of lambeosaurine duck-billed dinosaur, containing a single species, ''Olorotitan arharensis.'' It was among the last surviving non-avian dinosaurs to go extinct during the Cretaceous–Paleogene extinction event, having lived from the middle to late Maastrichtian-age of the Late Cretaceous era. The remains were found in the Udurchukan Formation beds of Kundur, Arkharinsky District, Amur Oblast, Eastern Russia, in the vicinity of the Amur River. Discovery and naming The holotype specimen of ''Olorotitan'', consisting of a nearly complete skeleton, was discovered in field work in the Udurchukan Formation of Kundur in the Amur region of Russia between 1999 and 2001. Pascal Godefroit and colleagues described and named it as a new species in 2003. It was the first nearly complete dinosaur specimen to be described from Russia, and is the most complete lambeosaurine skeleton discovered anywhere outside of western North America. Large numbers ...

Kazaklambia
''Kazaklambia'' is an extinct genus of herbivorous lambeosaurine dinosaur known from the Late Cretaceous Dabrazinskaya Svita (Santonian stage) of southern Kazakhstan. It contains a single species, ''Kazaklambia convincens''. Discovery and naming In 1961, a nearly complete skeleton of a hadrosaurid was found at the Syuk-Syuk locality of the Dabrazinskaya Svita of southern Kazakhstan, north of Tashkent, Uzbekistan. This was the second discovery of hadrosaurs in this region of southern Kazakhstan following the decades earlier excavation of ''Jaxartosaurus'', and the third hadrosaur discovery from Kazakhstan after ''Aralosaurus'' in 1957. The specimen, Paleontological Institute, Russian Academy of Sciences, PIN No. 2230, was an almost complete skeleton only missing the snout of the skull, the hands and left foot, and the end of the tail, being the most complete dinosaur known not only from Kazakhstan but also from the entire Soviet Union. PIN 2230 was described in 1968 in paleontolog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amurosaurus
''Amurosaurus'' (; "Amur lizard") is a genus of lambeosaurinae, lambeosaurine hadrosaurid dinosaur found in the latest Cretaceous period (66 million years ago)Godefroit, P., Lauters, P., Van Itterbeeck, J., Bolotsky, Y. and Bolotsky, I.Y. (2011). "Recent advances on study of hadrosaurid dinosaurs in Heilongjiang (Amur) River area between China and Russia." ''Global Geology'', 2011(3). of eastern Asia. Fossil bones of adults are rare, but an adult would most likely have been at least long. According to Gregory S. Paul, it was about long and weighed about . Discovery and naming Russian paleontologists Yuri Bolotsky and Sergei Kurzanov first described and named this dinosaur in 1991. The generic name is derived from the Amur River and the Ancient Greek, Greek word ''sauros'' ("lizard"). The Amur (called Heilongjiang or "Black Dragon River" in Chinese (language), Chinese) forms the border of Russia and China, and is near where this dinosaur's remains were found. There is one know ...

Minqaria
''Minqaria'' (meaning "beak") is a genus of lambeosaurine dinosaurs from the Late Cretaceous (Maastrichtian) Ouled Abdoun Basin of Morocco. The genus contains a single species, ''Minqaria bata'', known from a partial skull. Discovery and naming The ''Minqaria'' holotype specimen, MHNM.KHG.1395, was discovered in sediments of the Oulad Abdoun Basin (upper Couche III, Sidi Chennane locality) of Morocco. The specimen consists of a partial skull, including a right maxilla, left dentary, and braincase. In 2024, Longrich et al. described ''Minqaria bata'' as a new genus and species of arenysaurin hadrosaurid based on these fossil remains. The generic name, "Minqaria''", is Arabic for "beak". The specific name, "''bata''", is Arabic for "duck". Description ''Minqaria'' is estimated to have a length of about and a weight of , similar in size to its contemporary relative ''Ajnabia''. Since the braincase bones are fused, the ''Minqaria'' holotype likely belonged to a mature ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
