Lambeosaurinae
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] |
Ajnabia
''Ajnabia'' (meaning "stranger" or "foreigner") is a genus of lambeosaurine hadrosaur from the Late Cretaceous (Maastrichtian) of Morocco. It is the first definitive hadrosaur from Africa and is thought to be related to European hadrosaurs like ''Adynomosaurus'' and ''Pararhabdodon''. The discovery of ''Ajnabia'' came as a surprise to the paleontologists who found it because Africa was isolated by water from the rest of the world during the Cretaceous, such that hadrosaurs were assumed to have been unable to reach the continent. Discovery and naming ''Ajnabia'' was recovered from the Late Maastrichtian strata of the phosphate mines at Sidi Chennane, in Khouribga Province, Morocco. Recovered elements include most of the left maxilla and part of the right, and a fragment of the right dentary. The name ''Ajnabia'' derives from the Arabic أجنبي (''ajnabi''), meaning "strange" or "foreign", referring to the animal as part of a dinosaur lineage that immigrated to Africa from elsew ...

Aralosaurus
''Aralosaurus'' was a genus of hadrosaurid dinosaur that lived during the Late Cretaceous in what is now Kazakhstan. It is known only by a posterior half of a skull (devoid of its mandible) and some post-cranial bones found in the Bostobe Formation in rocks dated from the Upper Santonian-Lower Campanian boundary, at about 83.6 Ma (millions of years). Only one species is known, ''Aralosaurus tuberiferus'', described by Anatoly Konstantinovich Rozhdestvensky in 1968. The genus name means Aral Sea lizard, because it was found to the northeast of the Aral Sea. The specific epithet ''tuberiferus'' means bearing a tuber because the posterior part of the nasal bone rises sharply in front of the orbits like an outgrowth. ''Aralosaurus'' was originally reconstituted with a nasal arch similar to that of North American ''Kritosaurus'' (a comparison based on a specimen now placed in the genus ''Gryposaurus''). For many years, ''Aralosaurus'' was thus placed in the clade of the Hadrosaurinae. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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 ...

Taleta
''Taleta'' (meaning "three") is an extinct genus of lambeosaurine ornithopod dinosaurs from the Late Cretaceous (Maastrichtian age) Oulad Abdoun Basin of Morocco. The genus contains a single species, ''Taleta taleta'', known from two upper jaw bones. It is the third member of the clade Arenysaurini found from this locality, after ''Ajnabia'' and ''Minqaria''. Discovery and naming The ''Taleta'' holotype specimen, MHNM.KH.1557, was discovered in a layer of the Oulad Abdoun Basin (upper Couche III, Sidi Chennane locality) of Morocco. The specimen consists of a partial left and right (upper jaw bone). The bones were found in association and exhibit comparable preservation and morphology, implying they came from the same individual. In 2025, Nicholas Longrich and colleagues described ''Taleta taleta'' as a new genus and species of lambeosaurine hadrosaurs based on these fossil remains. The generic and specific names derive from an Arabic word meaning "three", referencing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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] |
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 ...

Nipponosaurus
''Nipponosaurus'' (meaning "Japanese lizard") is a Lambeosaurinae, lambeosaurine hadrosaur from sediments of the Yezo Group, in Sinegorsk on the island of Sakhalin, which was part of Japan at the time of the species' classification. The type species, type and only species is ''N. sachalinensis'', known only from a single Juvenile (organism), juvenile specimen discovered in 1934 and named in 1936, by Takumi Nagao, with further material of the same individual found in 1937. Since then, the taxon has been largely ignored, and its validity has been doubted, with synonymy with other Asian hadrosaurs or status as a ''nomen dubium'' being suggested. Redescriptions from 2004 and 2017, however, have supported recognition as a distinct species. Dating the only specimen has been difficult, but based on associated mollusc taxa, the species likely lived sometime in the upper Santonian or lower Campanian, around 80 million years ago.

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 ...
