Charonosaurus
''Charonosaurus'' ( ; meaning "Charon's lizard") is a genus of dinosaur whose fossils were discovered by Godefroit, Zan & Jin in 2000 on the south bank of the Amur River, dividing China from Russia. It is monotypic, consisting of the species ''C. jiayinensis''. Description ''Charonosaurus'' is a very large lambeosaurine hadrosaur, estimated around in length and in body mass.Holtz, Thomas R. Jr. (2012) ''Dinosaurs: The Most Complete, Up-to-Date Encyclopedia for Dinosaur Lovers of All Ages,'Winter 2011 Appendix./ref> It is known from a partial skull (Holotype: CUST J-V1251-57 (Changchun University of Sciences and Technology, Changchun, Jilin Province, China) found in the Late Maastrichtian Yuliangze Formation, west of Jiayin village, Heilongjiang Province, northeastern China. Adult and juvenile hadrosaur remains discovered in the same area and formation likely represent the same taxon and supply information on most of the postcranial skeleton; the femur length was up to 1.3 ...

Parasaurolophus
''Parasaurolophus'' (; meaning "near crested lizard" in reference to ''Saurolophus)'' is a genus of herbivorous hadrosaurid ornithopod dinosaur that lived in what is now North America and possibly Asia during the Late Cretaceous Period, about 76.5–73 million years ago. It was a herbivore that walked both as a biped and as 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 (Canada), New Mexico and Utah (United States), and possibly Heilongjiang (China). The genus was first described in 1922 by William Parks from a skull and partial skeleton found in Alberta. ''Parasaurolophus'' was a hadrosaurid, part of a diverse family of Cretaceous dinosaurs known for their range of bizarre head adornmen ...

Lambeosaurinae
Lambeosaurinae is a group of crested hadrosaurid dinosaurs. Classification Lambeosaurines have been traditionally split into the tribes or clades Parasaurolophini (''Parasaurolophus'', '' Charonosaurus'', others (?).) and Lambeosaurini (''Corythosaurus'', ''Hypacrosaurus'', ''Lambeosaurus'', others.). Corythosaurini (synonym of Lambeosaurini, see below) and Parasaurolophini as terms entered the formal literature in Evans and Reisz's 2007 redescription of ''Lambeosaurus magnicristatus''. Corythosaurini was defined as all taxa more closely related to ''Corythosaurus casuarius'' than to ''Parasaurolophus walkeri'', and Parasaurolophini as all those taxa closer to ''P. walkeri'' than to ''C. casuarius''. In this study, '' Charonosaurus'' and ''Parasaurolophus'' are parasaurolophins, and ''Corythosaurus'', ''Hypacrosaurus'', ''Lambeosaurus'', ''Nipponosaurus'', and '' Olorotitan'' are corythosaurins. However, later researchers pointed out that due to the rules of priority set for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amurosaurus
''Amurosaurus'' (; "Amur lizard") is a genus of 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 Greek word ''sauros'' ("lizard"). The Amur (called Heilongjiang or "Black Dragon River" in Chinese) forms the border of Russia and China, and is near where this dinosaur's remains were found. There is one known species (''A. riabinini''), named in honor of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charon
In Greek mythology, Charon or Kharon (; grc, Χάρων) is a psychopomp, the ferryman of Hades, the Greek underworld. He carries the souls of those who have been given funeral rites across the rivers Acheron and Styx, which separate the worlds of the living and the dead. Archaeology confirms that, in some burials, low-value coins were placed in, on, or near the mouth of the deceased, or next to the cremation urn containing their ashes. This has been taken to confirm that at least some aspects of Charon's mytheme are reflected in some Greek and Roman funeral practices, or else the coins function as a viaticum for the soul's journey. In Virgil's epic poem, ''Aeneid'', the dead who could not pay the fee, and those who had received no funeral rites, had to wander the near shores of the Styx for one hundred years before they were allowed to cross the river. Some mortals, heroes, and demigods were said to have descended to the underworld and returned from it as living beings. T ...

Hadrosaur
Hadrosaurids (), or duck-billed dinosaurs, are members of the ornithischian family Hadrosauridae. This group is known as the duck-billed dinosaurs for the flat duck-bill appearance of the bones in their snouts. The ornithopod family, which includes genera such as ''Edmontosaurus'' and ''Parasaurolophus'', was a common group of herbivores during the Late Cretaceous Period. Hadrosaurids are descendants of the Upper Jurassic/Lower Cretaceous iguanodontian dinosaurs and had a similar body layout. Hadrosaurs were among the most dominant herbivores during the Late Cretaceous in Asia and North America, and during the close of the Cretaceous several lineages dispersed into Europe, Africa, South America and Antarctica. Like other ornithischians, hadrosaurids had a predentary bone and a pubic bone which was positioned backwards in the pelvis. Unlike more primitive iguanodonts, the teeth of hadrosaurids are stacked into complex structures known as dental batteries, which acted as effecti ...

Lambeosaurini
Lambeosaurini, previously known as Corythosaurini, is one of four tribes of hadrosaurid ornithopods from the family Lambeosaurinae. It is defined as all lambeosaurines closer to ''Lambeosaurus lambei'' than to ''Parasaurolophus walkeri, Tsintaosaurus spinorhinus, or Aralosaurus tuberiferus'', which define the other three tribes. Members of this tribe possess a distinctive protruding cranial crest. Lambeosaurins walked the earth for a period of around 12 million years in the Late Cretaceous, though they were confined to regions of modern-day North America and Asia. History of classification The term Corythosaurini was first used by Brett-Surman in 1989, who characterized the taxon via reference to the premaxilary expansion into a hollow helmet-like cranial crest, as well as higher neural spines. The clade was formally defined via phylogenetic analysis by Evans and Reisz in 2007, and this was confirmed by multiple other analyses. In 2011, Sullivan ''et al.'' observed that by the ...

Parasaurolophini
Parasaurolophini is a tribe of derived corythosaurian lambeosaurine hadrosaurids that are native to Asia, and North America. It is defined as everything closer to ''Parasaurolophus walkeri'' than to ''Lambeosaurus lambei''. It currently contains ''Adelolophus'' (from Utah), possibly ''Angulomastacator'' (from Texas), '' Charonosaurus'' (from China), ''Parasaurolophus'' (from Utah, New Mexico, China and Alberta) and '' Tlatolophus'' (from Mexico).

Lambeosaurus
''Lambeosaurus'' ( , meaning " Lambe's lizard") is a genus of hadrosaurid dinosaur that lived about 75 million years ago, in the Late Cretaceous period (Campanian stage) of North America. This bipedal/quadrupedal, herbivorous dinosaur is known for its distinctive hollow cranial crest, which in the best-known species resembled a mitten. Several possible species have been named, from Canada, the United States, and Mexico, but only the two Canadian species are currently recognized as valid. Material relevant to the genus was first named by Lawrence Lambe in 1902. Over twenty years later, the modern name was coined in 1923 by William Parks, in honour of Lambe, based on better preserved specimens. The genus has a complicated taxonomic history, in part because small-bodied crested hadrosaurids now recognized as juveniles were once thought to belong to their own genera and species. Currently, the various skulls assigned to the type species ''L. lambei'' are interpreted as showing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Blasisaurus Canudoi
''Blasisaurus'' is a genus of lambeosaurine hadrosaurid dinosaur from the Late Cretaceous. It is known from a partial skull and skeleton found in late Maastrichtian-age rocks of Spain. The type species is ''Blasisaurus canudoi'', described in 2010 by Penélope Cruzado-Caballero, Xabier Pereda-Suberbiola and José Ignacio Ruiz-Omeñaca, a group of researchers from Spain. Naming and discovery The generic name refers to the ''Blasi 1'' site where the fossil was found. The specific epithet honours paleontologist José Ignacio Canudo. The holotype, MPZ99/667, is housed in Huesca. It was found in a layer of the Arén Formation dating from the upper Maastrichtian, about 66 million years ago. It consists of a skull with fragmentary lower jaws. Description ''Blasisaurus'' was a medium-sized ornithopod. Its describers identified two distinct features: the cheekbone has a rear projection with a hook-shaped upper edge and the lower sleep window is narrow and D-shaped. From the same forma ...
