Kentrosaurus is a two-star herbivore in Jurassic Park: Operation Genesis. It is one of two stegosaurs featured in the game, the other being Stegosaurus.


Kentrosaurus tends to be extremely cautious around large herbivores such as Brachiosaurus, usually going into a panic and running away from them. Due to this behavior, it is the only herbivore in the game not perfectly compatible with all other herbivores.

Kentrosaurus is the only small herbivore that will defend itself from large carnivores when under attack, although it offers little use when under attack from larger carnivores such as Tyrannosaurus rex.


Kentrosaurus becomes scared when around large herbivores, especially Brachiosaurus, and as a result may be distracted from eating, causing it to become stressed. It may also unintentionally hurt other small herbivores by swinging its tail in defense. However, there is one way to keep Kentrosaurus with other herbivores: the key idea is to have an enclosure large enough to keep Kentrosaurus away from large herbivores by placing a hatchery on one side of the enclosure and another on the other side of the same enclosure. One hatchery will hatch the large herbivores, and the other side will hatch Kentrosaurus as well as Stegosaurus, along with other small dinosaurs such as Dryosaurus. A herbivore such as Brachiosaurus will hardly wonder off too far to pose any issues in this kind of enclosure, but others that tend to wander more may cause problems.

Provided there is plenty of space between Kentrosaurus and Brachiosaurus, Kentrosaurus will remain perfectly fine in the enclosure, especially if Stegosaurus is around.

An alternative to the previous method involves modding the Kentrosaurus to use the same behavior class as stegosaurus. This can be done by opening the Kentro.ini file located in the JPOG/Units folder and changing the TClass entry to AUnitKentro to AUnitStego. Once this has been done Kentrosaurus will no longer be frightened of large herbivores.


  • There is an unused sound file in the Kentrosaurus sound directory named "kentRoar01.wav". It is likely that this would accompany a roaring animation which was cut from the final game.
  • Like Stegosaurus, Kentrosaurus' posture is wrong; real-life Kentrosaurus would have probably carried their tails vertically and their heads erect, like in The Lost World: Jurassic Park. Its plate arrangement is also wrong, as they would have been in two parallel rows as opposed to the alternating plate arrangement portrayed in JPOG.
  • Kentrosaurus and Stegosaurus lived on two differerent continents and would not have co-existed together.
  • Kentrosaurus has the highest health of all small herbivores. Ankylosaurus is the only dinosaur that can kill a Kentrosaurus in one hit.
