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

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. Unlike most of the other carnivores at the time it lived with, Allosaurus and Torvosaurus, which were advance carnivores, Ceratosaurus was a primitive carnivore with the number of fingers it had was four, which other carnivores had three.

In The Isle

Ceratosaurus is a medium sized carnivore that hunts Dryosaurus, Velociraptor, and other small dinosaurs in The Isle. While it is strong enough to face small dinosaurs, it must face larger prey items in pairs or packs.



  • The default skin is 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.
