Lambeosaurines
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] |
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] |
Late Cretaceous
The Late Cretaceous (100.5–66 Ma) is the more recent of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period. Climate During the Late Cretaceous, the climate was warmer than present, although throughout the period a cooling trend is evident. The tropics became restricted to equatorial regions and northern latitudes experienced markedly more seasonal climatic conditions. Geography Due to plate tectonics, the Americas were gradually moving westward, causing the Atlantic Ocean to expand. The Western Interior Seaway divided North America into eastern and western halves; Appalachia and Laramidia. India maintained a northward course towards Asia. In the Southern Hemisphere, Aus ...

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.

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 ...

Velafrons
''Velafrons'' (meaning "sailed forehead") is a genus of lambeosaurine hadrosaurid dinosaur from the Late Cretaceous of Mexico. It is known from a mostly complete skull and partial skeleton of a juvenile individual, with a bony crest on the forehead. Its fossils were found in the late Campanian-age Cerro del Pueblo Formation (about 72 million years oldLoewen, M.A., Sampson, S.D., Lund, E.K., Farke, A.A., Aguillón-Martínez, M.C., de Leon, C.A., Rodríguez-de la Rosa, R.A., Getty, M.A., Eberth, D.A., 2010, "Horned Dinosaurs (Ornithischia: Ceratopsidae) from the Upper Cretaceous (Campanian) Cerro del Pueblo Formation, Coahuila, Mexico", In: Michael J.

Sahaliyania
''Sahaliyania'' (from "black" in Manchu language, Manchu, a reference to the Amur River, Amur/Heilongjiang River) is a genus of lambeosaurinae, lambeosaurine hadrosaurid dinosaur (crested duckbilled dinosaur) from the Late Cretaceous of Heilongjiang, People's Republic of China, China. Discovery Its remains were found in a bonebed in the Maastrichtian-age Yuliangze Formation, alongside rarer remains of the hadrosaurinae, hadrosaurine hadrosaurid (flat-headed duckbill) ''Wulagasaurus''. ''Sahaliyania'' was named by Pascal Godefroit and colleagues in 2008. It is one of several hadrosaurids from the Amur River region named since 2000. The type species, type and only species to date is ''S. elunchunorum'', named in honor of the Oroqen people, Elunchun people. ''Sahaliyania'' is holotype, based on Geological Museum of Heilongjiang, GMH W453, a partial skull. Godefroit and colleagues assigned numerous other fossils from the bonebed to their new genus, representing much of the skull ...
