Parasaurolophus (/ ˌ p ær ə s ɔː ˈ r ɒ l ə f ə s,-ˌ s ɔːr ə ˈ l oʊ f ə s /; meaning "beside crested lizard" in reference to Saurolophus) [2] is a genus of hadrosaurid "duck-billed" dinosaur that lived in what is now western North America and possibly Asia during the Late Cretaceous period, about 76.9–73.5 million years ago. [3]
Saurolophus was an important early reference for other hadrosaurs, as seen in the names of Prosaurolophus ("before Saurolophus") and Parasaurolophus ("near Saurolophus"). However, little additional material has been recovered and described. Instead, more abundant remains from Asia have provided more data.
Juvenile Corythosaurus, along with adults, had a premaxilla-nasal fontanelle. Young and adult Corythosaurus are similar to Lambeosaurus and Hypacrosaurus, but dissimilar to Parasaurolophus in that the sutures of the skull are sinuous, not smooth and straight. This feature helps to differentiate Parasaurolophini from Lambeosaurini.

In a 2009 study by palaeontologist David C. Evans and colleagues, the brains of lambeosaurine hadrosaur genera Hypacrosaurus (adult specimen ROM 702), Corythosaurus (juvenile specimen ROM 759 and subadult specimen CMN 34825), and Lambeosaurus (juvenile specimen ROM 758) were scanned and compared to each other (on a phylogenetic and ontogenetic ...
Lambeosaurines originated on the continent of Laurasia during the Late Cretaceous, being initially found throughout modern Europe and Asia.Around the Campanian stage, lambeosaurines of the tribe Corythosauria colonized the landmass of Laramidia (modern western North America) via Beringia and spread as far south as Mexico, radiating into a diverse array of a body plans, including famous taxa ...
