As soon as Thorne, Malcolm, and Eddie arrive in Costa Rica, they prepare to head to Isla Sorna, despite government agents questioning why they want to go to the remote island. A helicopter transport takes them to the island. They arrange to be picked up the next day, giving them a day to find Levine.

Eddie, the crew’s mechanic, is immediately uncomfortable on the island. Even as they begin to unload the massive equipment they have brought—the trailers that house their computer lab, living quarters, ammunition, canisters of neurotoxins, a military-style Explorer vehicle, and a motorcycle for treacherous terrain—Eddie frets over the batteries they have brought. They are untested in such conditions. 

The search party heads into the jungle in their Ford Explorer which pulls the research trailers. They use the weak signal from Levine’s GPS to direct their search. When they approach a small stream, Thorne stops the vehicle. He spots a strip of green Gore-Tex presumably from Levine’s expedition pack. While examining the strip, Thorne is aware of a gathering of chicken-sized dinosaurs along the stream. They seem more curious than threatening. Although Eddie is apprehensive, Malcolm reassures him they are not hunters. They feed on carcasses and waste.
