***Chasmosaurus*** is a genus of ceratopsid dinosaur in the *Jurassic World Evolution* series, originating from Late Cretaceous North America. In *Evolution*, *Chasmosaurus* fossils are first unlocked on Isla Pena then excavated in the Dinosaur Park Formation, Horseshoe Canyon Formation, and Scollard Formation.

## Characteristics

Weighing around two tons and spanning approximately five meters in length, *Chasmosaurus* is an average-sized ceratopsian dinosaur with a condensed body type, similar in size to its relatives *Triceratops* and *Sinoceratops*, although it is significantly smaller than both. However, like *Triceratops*, *Torosaurus*, and *Pentaceratops*, *Chasmosaurus'* noticeable feature are three facial horns on its face (one on its snout and two above its eyes) and a wide rectangular frill. The frill would likely have been too fragile for defense so may have been for attracting mates, or identification within their herd. Its name translates to "*Opening Lizard*" because of the holes present in the frill bone structure to save weight. As with other ceratopsians, *Chasmosaurus* primarily moves in herds to afford it protection against carnivores.

Unlocked on Isla Pena, *Chasmosaurus* has average requirements and is otherwise relatively easy to take care of. 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.

## Gameplay

### *Evolution*

#### Behaviour

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

## Paleontology

*Chasmosaurus* was first discovered in 1898 by Canadian paleontologist Lawrence Morris Lambe in who excavated part of the dinosaur's neck frill from Berry Creek, California, USA, with a more comprehensive specimen being discovered in 1913 by Charles Sternbern in the Dinosaur Park Formation of Alberta, Canada, and from this the genus was named. It was initially classified as a genus of *Monoclonius*, but later findings confirmed it was a new discovery. Further remains have been found in the intervening years have identified two species of the genus, allowing experts to define new species within the *Chasmosaurus* genus. *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.

### Paleoecology

*Chasmosaurus* lived in Canada during the Late Cretaceous period, around 75 million years ago, and existed alongside numerous other dinosaurs including fellow ceratopsians *Centrosaurus* and *Styracosaurus* as well as the hadrosaurs *Parasaurolophus* and *Corythosaurus*, the ornithomimid *Struthiomimus*, the armored *Euoplocephalus* and *Edmontonia*, and the tyrannosaurids *Daspletosaurus* and the infamous *Tyrannosaurus*. It ate cycads, ferns, and palms, but there were probably many more considering that it lived in a wooded region. It used its powerful, durable beak to tear plants out of the ground, while its tough skin protected it from predators.

## Behind the scenes

The *Chasmosaurus* is one of several ceratopsian dinosaurs featured in *Jurassic World Evolution*, and was first revealed in a Species Profile on February 23, 2018. It plays a role in the Isla Pena Science Division mission *Needs Management*, in which the player must acquire at least 85% of its genome and release two into a secure enclosure.
