Corythosaurus is an extinct genus of hadrosaur dinosaur that lived in the Late Cretaceous period. Its name means "Helmet lizard". It is also known by the incorrectly spelled name, Carninthosaurus in the The Lost World: Jurassic Park script and media.[2][3][4]

In the game, Jurassic Park: Explorer, the following information is given about this creature:

Corythosaurus had hundreds of small interlocking teeth at the back of its jaw, allowing it to crush and grind plant matter. The bony crest on top of its head contained its nasal passage and may have been used as a sounding device.

Like other duckbills and some other late Cretaceous plant-eating dinosaurs, Corythosaurus had huge numbers of teeth crammed together into "batteries" forming a single grinding surface on each side of the upper and lower jaws. This allowed the dinosaur to process large amounts of food at once. The hadrosaurines had broad, "ducklike" snouts to cut a wide swathe through the herb layer, while lambeosaurines such as Corythosaurus had narrower snouts and presumably fed more selectively.

The most distinctive feature of the lambeosaurines was the hollow bony crest on top of the head. The size and shape of these crests varied greatly. As a result, different skeletons of Corythosaurus have been identified as belonging to at least seven different species. However, comparison of more than 20 skulls has shown that the crest changes as it grows and differs between the sexes. Only a single species is, therefore, now recognized. The large-crested individuals are thought to be the adult males. They probably used the crest to intimidate others males. The skin covering the crest may have been brightly coloured or patterned, and the hollow within the bone, which was connected to the airway, may have been used to produce distinctive honking calls.


The Corythosaurus clones had a greyish body with yellow patches and orange red crests.[5] It is much smaller than its original forebearer, being 7 meters (23.25ft) in length instead of 9 meters (30 ft).[6] Although the clones are capable of walking on all fours and two legs, it mostly stood upright, nearly dragging its tail, unlike the original.


The behavior of the Corythosaurus seem to be similar to the Parasaurolophus. In fact, those two hadrosaurs are shown to coexist with each other as seen in Jurassic Park III. They are peaceful herbivores with a non-threatening demeanor that gathered in herds, typically found in grasslands and most likely forests.



Corythosaurus originally had 97% of its genome mapped before the Isla Nublar Incident struck the island.[7] It is known that this species was prematurely recreated by InGen, and enough information would be recovered to be placed in an information sheet that could later be used by InGen hunters in 1997 during the Isla Sorna Incident (1997).[4]

It was then successfully recreated by InGen in the Embryonics Administration lab on Isla Sorna in secret after the acquisition of InGen by Masrani Global Corporation and after the passing of the Gene Guard Act, alongside Ankylosaurus, Spinosaurus, and Ceratosaurus.[5][7] The Corythosaurus were parented and fed in captivity until InGen abandoned the lab and released them into the wild.

Being bred illegally and far after the Isla Nublar Incident, it was not planned be an attraction in Jurassic Park.[8] However, it was featured in the mural for the Visitor Center's restaurant.[9]

Living in the wild[]

After being cloned and experimented on for a period of 9 months in the late 90's, the unnamed InGen personnel set the dinosaurs free alongside the other illegally bred dinosaurs.[7] Corythosaurus roamed freely across the island for years to come afterwards.

Being created illegally and against the knowledge of InGen or Masrani higher ups, it is unknown if the Corythosaurus and the other new dinosaurs were affected by or were even bred to include the lysine deficiency that affected the original dinosaurs. It is unknown how many Corythosaurus lived on the island, but they were known to have resided in the jungles of the northeast. In that region, their herds would roam alongside the related dinosaur Parasaurolophus.[5]

Jurassic Park III[]

Rescue of Eric Kirby[]

A herd of Corythosaurs and Parasaurolophus were grazing just outside of the InGen Compound that created them when Dr. Grant, Billy Brennan, Amanda, and Paul Kirby, and Udesky came out of the compound being chased by a pack of Velociraptor who unknown to them were after their eggs that Billy had secretly stolen from the raptors. The group ran through the herd of the two hadrosaur species causing a stampede. During the stampede, Billy nearly lost his backpack that contained the raptor eggs. The fleeing herd caused the group of humans to ultimately split up.[5]

Jurassic World: Fallen Kingdom[]

It is known that Corythosaurus was subject to cruelty at some point in the past, although it is unknown if there are any surviving populations left.[10]

Jurassic World: Dominion[]

The Department of Prehistoric Wildlife mentioned Corythosaurus as an animal living in herds that live with Parasaurolophus. One individual could possibly be seen in a drone image of an illegal breeding operation in Finsbury Park, London alongside the Parasaurs, proving that the species survived.[11]

Behind the scenes[]

Corythosaurus made an early appearance as one of the dinosaurs seen on the mural to the Visitor Center's restaurant in Jurassic Park.[9] The mural was painted by Michael Denering[12] and the painting itself is based on Guernica by Pablo Picasso.

In the script for The Lost World: Jurassic Park, Corythosaurus was originally going to be among the many dinosaurs featured in the film albeit mispronounced "Carninthosaurus".[13] In said script a Corythosaur was to originally be captured by the InGen Hunters[14][15] but was replaced in the final product by the Parasaurolophus nicknamed "Elvis". The Corythosaur captured in the script was described as being "red-crested".[14] Though it never physically appeared in the final film, it was seen on one of the fact sheets one of the hunters was carrying[1], but in the next shot the Corythosaur in this fact sheet this hunter was carrying changes to a Pachycephalosaurus,[16] though it returns back to a Corythosaurus when the Hunter and Dr. Burke flee with the agitated Pachy nicknamed "Friar Tuck".[17] Furthermore, Roland Tembo misidentifies the Parasaur Elvis as a Corythosaurus and tries to pronounce its name.[18] Corythosaurus also later had a physical appearance in the sequel Jurassic Park III. Interestingly, the Mighty Chronicles adaptation of The Lost World Jurassic Park and the The Lost World: Jurassic Park Official Annual depicted Corythosaurus as being captured in place of the Parasaur Elvis like in the script[3] and in the Topps comic The Lost World: Jurassic Park II Roland even fully identifies Elvis as a "Carinthosaur".[19]


A hadrosaur that resembles Corythosaurus seen in the Jurassic World storyboards for Jim Martin.

The concept design of the Corythosaurus for Jurassic Park III was based on features seen in illustrations by John Sibbick.[citation needed]

In the script for Jurassic Park III, Corythosaurus was to be among the dinosaurs seen on the riverbank after the protagonists escape from the aviary.[20] Originally, the stampede seen in the film was only going to contain Parasaurolophus, but director Joe Johnston and visual effects supervisor Jim Mitchell felt there needed to be more variety, so Corythosaurus was created for the film. The Corythosaurus depicted in the film was created from the Parasaurolophus model.[21]

In Jim Martin's storyboards for Jurassic World there is a hadrosaur near an early version of the Jurassic World Monorail that resembles either Corythosaurus intermedius (a different species from the Corythosaurus seen in Jurassic Park III which resembles Corythosaurus casuarius) or Hypacrosaurus.

Corythosaurus appeared in the Jurassic Park Institute Dinopedia under the possible synonym "Pteropelyx".
