Species Profile - Chasmosaurus

You’ve got another three-horned dinosaur... this time a Chasmosaurus. The top of its head features a wide frill. Too thin for protection, so it is hypothesized that it’s instead used to impress a potential mate. Which on the islands, cannot happen. I’m assured. As I was before.

Chasmosaurus is a genus of ceratopsid dinosaur that originated from Late Cretaceous North America. Chasmosaurus fossils are first unlocked on Isla Pena then excavated in the Dinosaur Park Formation, Horseshoe Canyon Formation, and Scollard Formation.


In Jurassic World Evolution, the base genome of the Chasmosaurus is primarily reddish-brown in color, with a creamy underbelly and faded blue and red streaks on its large frill. As with other ceratopsians, it primarily moves in herds to afford it protection against carnivores.[1]

An average sized ceratopsian, Chasmosaurus is similar in size to its relatives, Triceratops and Sinoceratops. Chasmosaurus has a condensed body type, a large rectangular frill, and three horns; one on its snout and two above its eyes. The dinosaur's base cosmetic genome is a grayish brown with faded blue and red streaks on its frill.

Unlocked on the second to last island of the main campaign, Chasmosaurus has average requirements and is otherwise relatively easy to take care of.


Like all other ceratopsians, Chasmosaurus will engage in a death duel with large and medium carnivores such as Tyrannosaurus and Ceratosaurus if provoked.



Chasmosaurus is a somewhat social animal and requires at least two more of its own kind to maintain a healthy comfort level but otherwise has an average maximum social and population limit. Additionally, Chasmosaurus is capable of living somewhat peacefully alongside small carnivores such as Proceratosaurus and Velociraptor, only occasionally engaging in non-fatal territorial fights.

Chasmosaurus will, as all herbivores do, socialize with others of its own species on occasion, but otherwise behaves very similarly to other ceratopsians.


Chasmosaurus was first discovered in 1898 by Lawrence Lambe in California, USA, with a more comprehensive specimen being discovered in 1913 by Charles Sternbern in Alberta, Canada.

Chasmosaurus' branch of ceratopsians, the Chasmosaurinae, are characterized by their long frills and small horns. The massive frills were most likely not used for combat, as they were too fragile and contained large openings in their skeletal structure, likely to reduce their weight. One theory suggests that they may have been able to flush blood into their frills to display vivid colors to attract mates or scare off rivals and predators.


Chasmosaurus lived alongside other dinosaurs such as the hadrosaurs Parasaurolophus and Corythosaurus, the ceratopsians Centrosaurus and Pentaceratops, the ornithomimid Struthiomimus, the armored Euoplocephalus and Edmontonia, as well as the tyrannosaurid Daspletosaurus. It ate cycads, ferns, and palms, but there were probably many more considering that it lived in a wooded region.



  • Chasmosaurus was the sixth dinosaur to receive a Species Profile, on 23 February.
