===Distinguishing characteristics===

A set of characters were indicated by Barnum Brown in 1914 to distinguish ''Corythosaurus'' from all other [[hadrosaurid]]s from Alberta. These include a comparatively short skull with a high helmet-like crest formed by the [[nasal bone|nasals]], [[prefrontal bone|prefrontal]]s, and [[frontal bone|frontals]]; the nasals not being separated in front by the [[premaxilla]]ries; a narrow beak with an expansion in front of an elongated naris; and a small narial opening.<ref name="brown1914p560"/>

In 1916, Brown expanded the character set to include even more features. In the revised version, these extra features include a comparatively short skull with a high helmet-like crest formed by nasals, prefrontals, and frontals; the nasals not being separated in front by premaxillaries; a narrow beak; expanded section in front of the elongated nares; a small narial opening; a vertebral formula of 15 cervicals, 19 dorsals, 8 sacrals, and 61+ caudals; possession of dorsal spines of a medium height; high anterior caudal spines; long chevrons; long scapulae that possess a blade of medium width; a radius considerably longer than the humerus; comparatively short metacarpals, an anteriorly decurved ilium; a long ischium with a foot-like terminal expansion; a pubis with an anterior blade that is short and broadly expanded at the end; a femur that is longer than the tibia; the phalanges of pes are short; that the integument over the sides and tail composed of polygonal tuberculate scales without pattern, but graded in size in different parts of the body; and a belly with longitudinal rows of large conical limpet-like scales separated by uniformly large polygonal tubercles.<ref name="brown1916p710"/> Again, the presumed traits of the snout are incorrect because Brown confused the praemaxillae with the nasal bones and the nasal bones with the frontals. Most of the postcranial traits are today known to be shared with various other lambeosaurines.
