Parasaurolophus tubicen is the largest species of Parasaurolophus with more complex air passages in its crest.Length 10-12m. Parasaurolophus cyrtocristatus is the smallest species, with a short rounded crest.Its small size and the form of its crest have led several scientists to suggest that it represents females of P.tubicen,but this is not approved. Both lived 76-73 million years ago in New Mexico and Utah, 76-73 million years ago (Late Cretaceous).
