Jurassic Park: Operation Genesis Cheats

Dino nerds are the hardest visitors to impress. A good way to impress
them is using Dinosaurs from the same time period (AKA late
cretaceous)that are mixed (Herbivores & Carnivore).They may also
get a kick out of Carnivore taking down a Herbivore.
If you don't have any dinosaurs from the same time period,use
Dinosaurs from the same place of discovery.(AKA Arizona or China)
