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 is unlocked by the Hammond Foundation on Isla Pena.

Description

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]

Palaeontology

Chasmosaurus lived alongside of other Dinosaurs such as the hadrosaurs Parasaurolophus and Corythosaurus, the ceratopsians Centrosaurus and Pentaceratops, the Ornithomimid Struthiomimus, the armoured Euoplocephalus and Edmontonia and the Tyrannosaurid Daspletosaurus.

Chasmosaurus once lived in what is now the province of Alberta in Canada. At one time there were many species of Chamsosaurus stretching from Canada to Texas, but these have been reassigned to new genera such as Mojoceratops. Chasmosaurus' branch of ceratopsians, the Chasmosaurinae, are characterised by their long frills with openings to reduce weight and small horns. The massive frills were most likely not used for combat, as they were too fragile. Instead, they may've been able to flush blood into the frill to display vivid colours to attract mates or scare off rivals and predators such as the tyrannosaurid Daspletosaurus.

A juvenile Chasmosaurus belli found in Alberta, Canada by Phil Currie et al., reveals that Chasmosaurus may have cared for its young, like its relative, Triceratops, is hypothesized to have done. The juvenile measured five feet long and was estimated to be three years of age and had similar limb and frill proportions to the adult Chasmosaurus. This indicates that Chasmosaurus was not fast moving, and that juveniles did not need to be fast moving either to keep pace with adults. The fossil was complete save for its missing front limbs, which had fallen into a sinkhole before the specimen was uncovered. Skin impressions were also uncovered beneath the skeleton and evidence from the matrix that it was buried in indicated that the juvenile ceratopsian drowned during a possible river crossing. Further study of the specimen revealed that juvenile chasmosaurs had a frill that was narrower in the back than that of adults, as well as being proportionately shorter in relation to the skull.

A Pentaceratops sternbergii specimen was once renamed into Chasmosaurus sternbergi, but this has found no acceptance. In 2000, George Olshevsky renamed Monoclonius recurvicornis Cope 1889 into Chasmosaurus recurvicornis as its fossil material is likely chasmosaurine;[20] this is a nomen dubium.

There were two species of Chasmosaurus: C. belli and C. russelli. Chasmosaurus belli was originally classified as another species of dinosaur: Monoclonius.
