A massive showdown between the T-rex and the Gigantosaurus is the culmination of Jurassic World Dominion‘s finale and the dino fight is actually a rematch 65-million years in the making. Directed by Colin Trevorrow, Jurassic World Dominion reunites the three heroes from Jurassic Park, Dr. Alan Grant (Sam Neill), Dr. Ellie Sattler (Laura Dern), and Dr. Ian Malcolm (Jeff Goldblum), and teams them up with Jurassic World‘s good guys, Owen Grady (Chris Pratt), Claire Dearing (Bryce Dallas Howard), and Maisie Lockwood (Isabella Sermon). Meanwhile, the original T-rex from Jurassic Park is also back, having been transplanted to BioSyn’s sanctuary in Italy’s Dolomite Mountains.
Jurassic World Dominion‘s prologue (which was released in 2021 but isn’t part of the actual film) explained the ancient history between the T-rex and the Gigantosaurus. 65-million years ago during the Cretaceous age, a Gigantosaurus encountered a Tyrannosaurus Rex. The two massive apex predators fought and the larger and more powerful Gigantosaurus killed the T-rex. A fly then fed on the blood of the dead carnivore and was then caught in tree sap, which preserved it in amber. It was this very fly containing the blood of the dead T-rex that InGen scientists found and extracted the dinosaur’s DNA from when John Hammond’s (Richard Attenborough) genetics company began cloning dinosaurs. Therefore, the T-rex in Jurassic Park that survived into Jurassic World Dominion is the clone of the same T-rex the Gigantosaurus killed 65-million years ago. After Jurassic Park, the T-rex wasn’t seen again until Jurassic World in 2015. The next two Jurassic movies, The Lost World: Jurassic Park and Jurassic Park III, were set on Isla Sorna AKA Site B and both featured different T-rexes genetically engineered by InGen.
