Hissing, the primitive and lethal carnivore expands and shakes his hidden fans on his neck announcing his attack, he’s about to expel his tar poison aiming for his prey’s eyes to stun them before jumping to devour them. Originally alive during the Jurassic Period before the mosquitoes were confirmed by the fossil record, and with more gaps than usual in his DNA sequence, he was recreated by InGen with the Yellow-Banded Poison Dart Frog DNA to fill the gaps in his genetic sequence, resulting in an even deadlier creature, with traits the original never had. As seen already in the trailer threatening Claire Dearing, Iron Studios created the Dilophosaurus statue, standing over a pedestal of wild terrain with the movie’s logo.

As originally seen in Jurassic Park (1993), Dilophosaurus was the specimen responsible for the death of the corrupt programmer Dennis Nedry. Seventeen Dilophosaurus were recreated by InGen on their complex in Isla Sorna. While still young they hunted in packs, but only the leader had permission to kill the prey.
