21452 Benson et al . ( 2012 ) estimated that Corythosaurus has an average length of 9 metres ( 30 ft ) . Richard Swann Lull 's earlier length estimate , published in 1942 , found a slightly longer total length of 9 @.@ 4 m ( 31 ft ) , a size similar to Lambeosaurus lambei , another Canadian lambeosaurine . In 1962 , E... |

21453 Proportionally , the skull is much shorter and smaller than that of Edmontosaurus ( formerly Trachodon ) , Kritosaurus , or Saurolophus , but when including its crest , its superficial area is almost as large . |

21455 Over twenty skulls have been found from this dinosaur . As with other lambeosaurines , the animal bore a tall , elaborate bony crest atop its skull , which contained the elongate narial passages . The narial passages extended into the crest , first into separate pockets in the sides , then into a single central ... |

21456 The crests of Corythosaurus resemble that of a cassowary , or a Corinthian helmet . They are formed by a combination of the praemaxillae , nasals , prefrontals and frontals , as in Saurolophus , but instead of projecting backwards as a spine , they rise up to make the highest point above the orbit . The two halv... |

21457 The nasals make up most of the crest . Brown assumed that they extended from the beaks ' tip to the highest spot along the crest and that , unlike those in other genera , the nasals meet in the centre and are not separated in front by an ascending premaxillary process . Brown however , mistook the praemaxillae f... |

21458 The mouth of the holotype of Corythosaurus is narrow . The praemaxillae each form two long folds . The folds enclose air passages extending the narial passages to the front of the snout . There they end in narrow openings , sometimes called " pseudonares " , false bony nostrils . These were mistaken by Brown for... |

21468 Originally , Brown referred to Corythosaurus as a member of the family Trachodontidae ( now Hadrosauridae ) . Inside Trachodontidae were the subfamilies Trachodontinae and Saurolophinae . Brown classified Hadrosaurus , Trachodon , Claosaurus , and Kritosaurus in Trachodontinae , and Corythosaurus , Stephanosauru... |

21469 Later , Brown revised the phylogeny of Corythosaurus , and found that it was closely related , and possibly ancestral to Hypacrosaurus . The only differences he found between them were the development of the vertebrae , and the proportions of the limbs . During a study of dinosaurian ilia in the 1920s , Alfred S... |

21470 Corythosaurus is currently classified as a hadrosaurid , in the subfamily Lambeosaurinae .

However , research published in 2003 has suggested... |

21476 When they were first described , crested hadrosaurs were thought to be aquatic , an assessment based incorrectly on webbing that is now known to be padding . The theory was that the animals could swim deep in the water , and use the crest to store air to breath . However , it has now been proven that the crest d... |
