Dinosaurs with Mad Cow Disease. Don't laugh, it was a major plot point to the Lost World novel. Feeding your cloned dinosaurs modern farm animals is a big no-no. Makes the raptors go crazy and resort to cannibalism. Oh and the Costa Rican chapter of the Men in Black who deal with dead dinos washing up on the beach every so often. And the fact that instead of frog DNA, Jurassic Park's Carnotauruses were blended with chameleons....they are the perfect ambush predator.
