A scooper for Dark Horizons, revealed some storyline details about the forthcoming"Jurassic Park 4". Set 12 years after the first movie, John Hammond’s dinosaurs have apparently become urban legend. Most of the public has become skeptical they ever existed. Part of the plot involves the discovery of previously unidentified lizard-like animals showing up on mainland Costa Rica and conflicting with the locals (killing them?). To find out what the heck is going on, a team of experts chart an expedition to one of the off-shore islands. They find out the dinosaurs are thriving and breeding at an uncontrollable rate, so much so that it poses a threat to the nearby continent. They must find a way to curb the spread of the dinos or face an ecological disaster.
