Isla Sorna, Isla Nublar[]
Illustration by T-PEKC of JPLegacy.
Length: 15 feet
Height: 7 feet
Weight: 350
Lived during the Mid Jurassic period.
Coloration:
- Male: Green with darker green back blotches and pale yellow underbellies. Nose horn is red, and the back of the head is adorned with grey quills.
- Female and juvenile (both sexes): Like the male, but without the quills and a gray horn.
Diet: Proceratosaurus is mostly a scavenger of dead or near-dead beached animals including fish, turtles, cetaceans and prehistoric marine reptiles. It will also consume live turtles and seabirds (when it can catch them), as well as the eggs and young of turtles, seabirds, and Nothosaurus. In addition, Proceratosaurus will attack colonies of seals on the shoreline, sometimes even swimming into the water after their mammalian prey. If in a pack, it will attack larger prey.
Preferred Habitat: Along coasts and estuaries.
Social Structure: Individual or small packs with no real heirarchy.
Proceratosaurus is a smaller, earlier (if distant) relative to the gigantic, better-known Tyrannosaurus. The most notable feature of this dinosaur is the small nose horn, similar to that of Ornitholestes and Ceratosaurus. Like a male sornaensis Raptor, male Proceratosaurus have quills at the back of the head. These quills are spikier than those of the raptor and are incapable of movement. Like its giant relative, Proceratosaurus has incredibly strong jaws capable of crushing the shells of turtles and marine animal bones.
Proceratosaurus is the beachcomber of Islas Sorna and Nublar, and is often seen prowling the coastlines of the islands in search of the bodies of dead and dying animals washed up from the ocean. Being such a dedicated beachgoer, this dinosaur has a salt gland which allows it to drink right from the ocean itself. Like a marine iguana, it expels the excess salt through its nostrils in a 'spitting' action. This can surprise many dinosaurs, especially those familiar with the spitting Dilophosaurus, and so it is useful as a bluff defense.
When not found at the beach, Proceratosaurus frequents rivers and channels where it has a symbiotic relationship with Baryonyx. Proceratosaurus has a much better eye for danger and when it sees larger predators it reacts with a high-pitched warning screech. As a result Proceratosaurus is tolerated by Barynonyx and is often allowed access to the partially-eaten remains of Baryonyx' fish prey.
Unique among theropods, Proceratosaurus has an odd form of locomotion, consisting more of hops and jumps than steps and leaps. Its calls are also unique, consisting of hissing, hooting, barking and bizarre duck-like quacks. Proceratosaurus were known to steal meals from dilophosaurus.
