==Discovery and species== [[File:Corythosaurus.jpg|thumb|left|Fossil holotype specimen AMNH 5240 partially covered in skin impressions]] The first specimen, [[American Museum of Natural History|AMNH]] 5240, was discovered in 1911 by [[Barnum Brown]] in [[Red Deer, Alberta|Red Deer River]] of [[Alberta]] and secured by him in the Fall of 1912.<ref>Lowell Dingus and Mark Norell'', 2011 Barnum Brown: The Man Who Discovered'' Tyrannosaurus rex, University of California Press, p. 143</ref><ref name="brown1914p559" /> As well as an almost complete skeleton, the find was notable because impressions of much of the creature's skin had also survived.<ref name="brown1914p560" /> The specimen came from the [[Belly River Group]] of the province.<ref name="brown1914p559" /> The left or underside of the skeleton was preserved in carbonaceous clay, making it difficult to expose the skin to the elements.<ref name="brown1914p560" /> The skeleton was articulated and only missing about the last {{convert|0.61|m|ft|}} of the tail and front legs.<ref name="brown1914p560" /> Both [[scapula]]e and [[coracoid]]s are preserved in position, but the rest of the front legs are gone (except for [[Phalanx bone|phalanges]] and pieces of the [[humerus|humeri]], [[ulna]]e, and [[Radius (bone)|radii]]). Apparently, the remaining front legs were weathered or eroded away.<ref name="brown1914p560"/> Impressions of the integument were preserved covering over a large part of the skeleton’s outlining and shows the form of the body.<ref name="brown1914p560"/> Another specimen, AMNH 5338, was found in 1914 by Brown and [[Peter Kaisen]]. Both specimens are now housed in the [[American Museum of Natural History]] in their original death poses.<ref name="norrell2000p159"/> [[File:Corythosaurus excavation.jpg|thumb|Excavation of the holotype specimen of ''C. casuarius'' by the Red Deer River]] The [[type species]], ''Corythosaurus casuarius'', was named by Barnum Brown in 1914, based on the first specimen collected by him in 1912. AMNH 5240 is thus the [[holotype]]. In 1916, the original author, Brown, published a more detailed description that was also based on AMNH 5338, which is therefore the [[plesiotype]]. ''Corythosaurus'' is among many lambeosaurines that possess crests and it was the crest that lends ''Corythosaurus'' its name. The generic name ''Corythosaurus'' is derived from the Greek κόρυθος,(''korythos''), "Corinthian helmet", and means "helmeted lizard".<ref name="norrell2000"/> The [[specific name (zoology)|specific name]], ''casuarius'', refers to the [[cassowary]], a bird with a similar skull crest. The full [[binomial nomenclature|binomial]] of ''Corythosaurus casuarius'' thus means "Cassowary-like reptile, with a Corinthian helmet crest".<ref name="carnegie">{{cite web|title=DinoGuide: ''Corythosaurus casuarius''|url=http://www.carnegiemnh.org/online/dinosaurs/corythosaurus.html|work=Dinosaurs in Their Time|publisher=Carnegie Museum of Natural History|access-date=2014-07-27|archive-url=https://web.archive.org/web/20140810062925/http://www.carnegiemnh.org/online/dinosaurs/corythosaurus.html|archive-date=2014-08-10|url-status=dead}}</ref> [[File:Hunting dinosaurs in the bad lands of the Red Deer River, Alberta, Canada; a sequel to The life of a fossil hunter (1917) (20135543774).jpg|thumb|left|Quarry with one of the specimens lost at sea in 1916]] The two best preserved specimens of ''Corythosaurus'', found by [[Charles H. Sternberg]] in 1912, were lost on December 6, 1916, while being carried by the ''[[SS Mount Temple]]'' to the [[United Kingdom]] during [[World War I]]. They were being sent to [[Arthur Smith Woodward]], a paleontologist of the [[British Museum of Natural History]] in [[England]], when the ship transporting them was sunk by the German [[merchant raider]] {{SMS|Möwe|1914|6}} in the middle of the ocean.<ref name="sternberg1917">p. 495 in Tanke, D.H. & Carpenter, K. (2001).</ref> There were formerly up to seven species described, including ''C. casuarius'', ''C. bicristatus'' (Parks 1935), ''C. brevicristatus'' (Parks 1935), ''C. excavatus'' (Gilmore 1923), ''C. frontalis'' (Parks 1935), and ''C. intermedius'' (Parks 1923). In 1975, [[Peter Dodson]] studied the differences between the skulls and crests of different species of lambeosaurine dinosaurs. He found that the differences in size and shape may have actually been related to the sex and age of the animal. Only one species is currently recognized for certain, ''C. casuarius'',<ref name=PD75 /> although ''C. intermedius'' has been recognized as valid in some studies. It is based on specimen ROM 776, a skull found by [[Levi Sternberg]] in 1920, was named by [[William Parks (paleontologist)|William Parks]] in 1923. Originally, he named it ''[[Stephanosaurus]] intermedius'' earlier that year.<ref>{{cite journal | last1 = Parks | first1 = W.A. | year = 1923 | title = New species of crested trachodont dinosaur | journal = Bulletin of the Geological Society of America | volume = 34 | page = 130 }}</ref> The specific name of ''C. intermedius'' is derived from its apparent intermediate position according to Parks.<ref name="parks1923">{{cite journal | last1 = Parks | first1 = W.A. | year = 1923 | title = ''Corythosaurus intermedius'', a new species of trachodont dinosaur | journal = University of Toronto Studies, Geological Series | volume = 15 | pages = 5–57 }}</ref><ref name="vecchia2013"/><ref name="campioneetal2013">{{cite journal | last1 = Campione | first1 = N.
