Which dinosaur is the main predator in Jurassic Park III?

Spinosaurus is the main predator in Jurassic Park III.

The film presents a Spinosaurus as the dominant large carnivore encountered by Alan Grant and the rescue party on Isla Sorna. Its most memorable sequence is a confrontation with a Tyrannosaurus, after which the Spinosaurus continues as the movie’s principal threat.

Spinosaurus was a real theropod dinosaur that lived during the Cretaceous Period. Fossils indicate that it had an elongated, crocodile-like snout and distinctive neural spines forming a sail along its back. Evidence also suggests adaptations for a partly aquatic lifestyle.

The movie’s depiction is a dramatic interpretation rather than a complete scientific reconstruction. Jurassic Park traditionally made the Tyrannosaurus its signature predator, so the Spinosaurus’s central role in the third film was a notable change.
