Isla SornaEdit

Styracosaurus

Illustration by Arioch of JPLegacy.

Length: 18 feet
Height: 6 feet
Weight: 3 tons

Coloration:

Male: Overall a dark blue mottling with darker blue forked stripes running along the back. Black horns. Both sexes are capable of flushing blood into its frill to create pink rings or spots.
Female and juvenile (both sexes): Overall amber in colour, with paler yellow markings on the frill and lower part of the body and short yellow stripes from the middle of the back down to the top of the tail. Horns are beige.

Diet: Very flexible omnivores, will eat a wide range of flora including grass, ferns, fruits and flowers. Their sharp beaks are very powerful, allowing them to crack open coconuts, melons and crush bone. Like modern macaws, Styracosaurus will occasionally scavenge carrion.

Preferred Habitat: Large open areas with an excess of grass, ferns and flowering plants. Individuals will occasionally wander into forested areas to scavenge for fruits littered on the forest floor. When migrating, Styracosaurus prefer to travel via beaches and riverbanks to avoid the dense and treacherous Jungle.

Social Structure: Large herds, occassionally mingling with herds of Triceratops.


Styracosaurus is the spikiest of Isla Sorna's dinosaurs, with a massive nose horn and eight long spikes decorating the frill. This dinosaur displays sexual dimorphism, in that the colours of the male and the female are vastly different, allowing individuals to recognize members of the opposite sex despite their poor eyesight.

Like a rhinoceros, Styracosaurus' eyesight is very poor and it relies on its heightened sense of smell to detect food and danger. When grazing, Styracosaurus will create a circular formation with the large healthy members on the outer rim facing outward, while the smaller individuals, juveniles, and the other vulnerable members of the herd feed safely within the circle. Breaching the barrier of horns is near impossible and any predator would be wise to avoid a healthy-sized herd, however if a threat does occur the individuals on the outer rim will snort and bellow at the predator, waving their large, spiky heads and their dangerous nose horns to try and convince the predator to find an easier meal elsewhere. Somewhat like Centrosaurus on Lagarto, Styracosaurus can flush each side of its frill with blood, producing pink rings or spots which are far more striking against the blue of the males. If all else fails, then charging the predator is a last resort. At the end of the charge the Styracosaurus will thow its head up to drive its horn straight into the belly of the aggressor.

Styracosaurus has very large nasal cavities, which act as resonating chambers and enables the animal to emit a range of very loud low frequency wails reminiscent of a diesel freight train siren. These sounds can be distinguished by other members of the same species as either mating calls, general communication or distress calls.

Styracosaurus socialise very little with other dinosaur species, however it does occassionally mingle with its larger relative Triceratops.
