Guanlong

Guanlong is a genus of proceratosaurs. They were a planned attraction in the park, but those plans were canceled in favor of dilong. Ever since, the existing individuals had been released and have been rapidly breeding ever since. They had become a predator of the native deer. In extinction, it's revealed that they had begun breeding a month after release. They lay 20 eggs a clutch. Half those survive into adulthood. The rest are eaten by citipati. Guanlong is one of the only dinosaurs to be engineered to have the DNA of modern animals.
