 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 which was also based on AMNH 5338 , which specimen 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 Greek κόρυθος , korythos , " Corinthian helmet " , and means " helmeted lizard " . The specific name casuarius refers to the cassowary , a bird with a similar skull crest . The full binomial of Corythosaurus casuarius thus means " Cassowary @-@ like reptile , with a Corinthian helmet crest " .
