Ceratosaurus is a ceratosaurid from the late Kimmeridgian and early Tithonian faunal stages of the Late Jurassic epoch.

In Real Life

Ceratosaurus was a medium sized carnivore that preyed on small dinosaurs like Dryosaurus, as well as fish, crocodiles and other small and mid-sized animals.

Ceratosaurus had a large skull with large teeth, as well as short but powerful front limbs. It likely used the head as it's main weapon, as the front limbs are too small for full combat use.

One of Ceratosaurus most distinct features was the nasal crest from which the name derives; most paleontologists agree that it would have been for display, meaning the crest would probably have been brightly colored in life.

Similar to it's relative Carnotaurus, Ceratosaurus had a row of osteoderms running down it's back; given their blunt shape and position, they were likely display or species recognition tools, and not armor or weapons. The tail of Ceratosaurus comprised about half of the body's total length and was thin and flexible with high vertebral spines.

Ceratosaurus was found in the Morrison Formation of North America and the Lourinhã Formation of Portugal and possibly the Tendaguru Formation of Tanzania. It's relatives include Genyodectes, Elaphrosaurus, the abelisaurs Majungasaurus, Rugops, and Carnotaurus. While most theropods at the time had only three fingers on each hand, Ceratosaurus retained the ancestral fourth digit.

In The Isle

The Ceratosaurus is a quicker medium sized carnivore that hunts small-medium sized creatures roaming the island. While capable of bullying smaller predators off their kills and giving slightly larger ones a nasty fight, it should generally avoid dinosaurs significantly bigger than itself.

The Ceratosaurus preys on small and medium sized dinosaurs such as Pachycephalosaurus, Dilophosaurus, smaller sub-adult apexes and juvenile dinosaurs. It is also strong enough to challenge the Carnotaurus or a young adult Allosaurus, especially when in a forested area where it can use its' superior agility to maneuver around and flank its’ rivals. In the event that the Ceratosaurus encounters a larger, more powerful carnivore such as a Tyrannosaurus or Giganotosaurus, it is fast enough on its’ feet to make an easy getaway.

General overview:


  • Good all-rounder and very agile.
  • Fast, high damage output, heal rate and high stamina  
  • Quick stamina regen 
  • Great at taking down small and medium dinos.
  • Relatively short grow time and low hunger.
  • Very good turn radius.


  • Low bleed resistance and bleed damage.
  • Mediocre ambush (1.1x multiplier for 8 seconds)
  • Needs a pack to take down large prey.



  • The original default skin was based off the Ceratosaurus from Jurassic Fight Club.
  • Based off the Diabloceratops dossier, Ceratosaurus hunts Diabloceratops in packs due to the weight class of Diabloceratops being big for its size.
