The version of Isla Sorna of Jurassic Park: Trespasser is quite different from novel or movie canon. The island is 3 km in length and 1.5 km width. The topography of this island is based on Cocos Island, a real island on the west coast of Costa Rica.

Dinosaurs
Confirmed dinosaur species InGen released on the island:
While no living specimen appears in the game, several Allosaurus skulls can be found. The final boss of the game is an oversized raptor, possibly a Utahraptor. In two unused quotes, Hammond gives both a description of a Gallimimus, and mentions an Apatosaurus, but neither are seen in-game.
