Is This New Jurassic Island Site C?
Jurassic World Rebirth’s trailerreveals InGen owned a third, heretofore unnamed dinosaur island, which is effectively InGen’s Site C.

Even though Jurassic World: Dominion wrapped up several major story arcs, it has officially been announced that Jurassic World 4 is happening.
Jurassic World Rebirth’s main characters, led by Zora Bennett (Scarlett Johansson), mount an expedition to this newJurassiclocale. Their mission is to extract the DNA from three of the most dangerous dinosaurs to develop a medicinal miracle drug.

What The Purpose Of Site C Is & How It Connects To Jurassic Park
Jurassic World Rebirth’s Island Is Far From Jurassic Park
Jurassic World Rebirth’s Site C island was the research facility InGen used to develop and test dinosaurs. Ominously,Site C is where InGen stored the"worst of the worst"i.e. the dinos they cloned that were too uncontrollable or dangerous to be admitted into Jurassic Park’s zoos and enclaves. Among the beasts left on InGen’s third island are several Spinosaurus, an even more dangerous T-Rex, a Mosasaurus, and a new kind ofmutant hybrid dinosaur.
Every Dinosaur In Jurassic World Rebirth Explained
Jurassic World Rebirth includes a wide range of dinosaurs with some returning after past appearances and others making their franchise debuts.
Abandoned and overrun by the deadliest of the cloned prehistoric creatures for over three decades,Site C is more dangerous than Isla Sorna or Isla Nublar were. The distance between the Costa Rican islands and Site C is evidence of how vital it was to InGen that their"worst"creations were kept far away from Jurassic Park. However, this also means thatJurassic World Rebirth’s island was unaffected by the volcanic cataclysm that destroyed Isla Nublar inJurassic World: Fallen Kingdom.

Jurassic World Rebirth’s New Island Retcons The Purpose Of Isla Sorna
What Was Site B For In Jurassic Park Has Changed
Jurassic World Rebirth’s new islandeffectively retcons the purpose of Isla Sorna inThe Lost World: Jurassic Parkby supplanting it.The Lost World’s retcon toJurassic Parkwas that Isla Sorna became where InGen cloned the dinosaurs, which were then brought to Isla Nublar for Jurassic Park’s zoo.The Lost World’s retcon undermined the scene inJurassic Parkthat showed the genetics lab in Isla Nublar, implying the dinosaurs were cloned and born on-site in Jurassic Park.
It’s also possible that Jurassic World Rebirth’s island was used mainly to test super predator dinosaurs.

Site C inJurassic World Rebirthretconned as InGen’s dinosaur research and testing facility could mean Isla Sorna is now where dinosaurs were brought for further evaluation before moving to Jurassic Park. It’s also possible thatJurassic World Rebirth’s island was used mainly to test super predator dinosaurs, since Site C only seems to contain InGen’s deadliest carnivorous creations.
Jurassic World Rebirth’s New Island Doesn’t Make Sense
How Many Dinosaur Islands Did InGen Own, Anyway?
Jurassic World Rebirthwill have to justifywhy and how InGen owned three separate islands to breed and store cloned dinosaurs, and what, exactly, differentiates Site C from Isla Sorna. Another complication isJurassic World’s reboot that InGen was acquired by Masrani Global Corporation, which funded and opened the Jurassic World theme park. Did Masrani know about Site C, and if not, how is that possible?
Jurassic World Rebirth Is Secretly Telling Us The Best Thing About The Franchise Will Return In The Scarlett Johansson Movie
The early-stage marketing for Gareth Edwards’ Jurassic World Rebirth is sneakily pointing to the return of one of the best features of the original.
After all, there was no mention whatsoever of a third dinosaur island in the threeJurassic Worldfilms. However, this could also be justified byJurassic World Rebirth. If the island near Barbados contained dinosaurs too dangerous for Jurassic Park, then isolating it and keeping it a secret may have been for the protection of the dinos and the outside world. This may also explain why Site C was never raided forJurassic World: Fallen Kingdom’s dinosaur auction that subsequently let the prehistoric beasts loose on the world inJurassic World Dominion.
