Dilophosaurus is the smallest (and weakest) carnivorous dinosaur within Jurassic Park: Operation Genesis. It kills by spitting venom, much in the movie, but will only attack small herbivores such as dryosaurus and gallimimus. Interestingly, it will not attack people or animals by spitting through the open spaces in fences, much less even see them.


It is interesting to note that a Dilophosaur pack leader keeps its frill open, while others have theirs folded. Dilophosaurs can coexist with Velociraptors, provided the Velociraptors are not rampaging and have plenty of food.

Dilophosaurus will mostly attack small unarmed herbivores, although they have been recorded attacking Kentrosaurus on several occasions. Dilophosaurus are virtually defenseless against larger dinosaurs. However, there have been occasions where Dilophosaurs have actually attacked and killed Velociraptors, although this only usually occurs when they are desperate for food.

In real life Edit

Dilophosaurus lived in the Early Jurassic period in an area that is now the Kayenta Formation in modern Arizona. The largest carnivore at the time, it would have been the top predator and preyed on smaller creatures such as Scuttelosaurus and prosauropods. The main distinguishing feature of Dilophosaurus is the pair of thin crests on its head. These were most likely used as display for mates, much like the colourful beaks, feathers and wattles on modern day birds. Dilophosaurus males may have performed elaborate courtship dances and displays for females.

It should also be noted that in reality, Dilophosaurus most likely never had an extendable frill or the ability to spit poison also its real life counterpart is larger then the animal in game in real life Dilophosaurus is estimated to grow up to 7 meters long .


  • Dilophosaurus cannot kill cleaners, likely due to a bug.
  • Dilophosaurus actually lived in the Early Jurassic, rather than the Mid Jurassic.
  • Like Ceratosaurus and Albertosaurus, Dilophosaurus will not rampage, and if a cheat is entered to make them do so, they will go comatose.
