Jurᴀssic World Rebirth introduces a major retcon to the history of Jurᴀssic Park and InGen’s islands populated by dinosaurs. Directed by Gareth Edwards and written by David Keopp, Jurᴀssic World Rebirth premieres July 2, 2025. Jurᴀssic World Rebirth is the fourth Jurᴀssic World movie since the franchise was rebooted in 2015, and the seventh movie in the Jurᴀssic franchise that began in 1993 with Steven Spielberg’s classic Jurᴀssic Park.
The Jurᴀssic saga is no stranger to retcons. Jurᴀssic Park was originally stand-alone until the film became a global blockbuster in the summer of 1993, Novelist and Jurᴀssic Park creator Michael Crichton penned a follow-up, The Lost World, but his story was largely excised by Steven Spielberg’s 1997 sequel, The Lost World: Jurᴀssic Park, in favor of a new plot. The Lost World introduced a major retcon by creating Isla Sorna AKA Site B, a second island owned by the dinosaur-cloning InGen corporation along with Isla Nublar, the setting of the original Jurᴀssic Park.
Jurᴀssic World Rebirth Reveals A Third Dinosaur Island
Is This New Jurᴀssic Island Site C?
Jurᴀssic World Rebirth‘s trailer reveals InGen owned a third, heretofore unnamed dinosaur island, which is effectively InGen’s Site C. Unlike Isla Nublar and Isla Sorna, which are located near Costa Rica in Central America, Jurᴀssic World Rebirth‘s new island is somewhere near Barbados in the Caribbean.
Jurᴀssic World Rebirth’s main characters, led by Zora Bennett (Scarlett Johansson), mount an expedition to this new Jurᴀssic locale. 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 Jurᴀssic Park
Jurᴀssic World Rebirth’s Island Is Far From Jurᴀssic Park
Jurᴀssic 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 Jurᴀssic 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 of mutant hybrid dinosaur.
Abandoned and overrun by the ᴅᴇᴀᴅliest 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 Jurᴀssic Park. However, this also means that Jurᴀssic World Rebirth‘s island was unaffected by the volcanic cataclysm that destroyed Isla Nublar in Jurᴀssic World: Fallen Kingdom.
Jurᴀssic World Rebirth’s New Island Retcons The Purpose Of Isla Sorna
What Was Site B For In Jurᴀssic Park Has Changed
Jurᴀssic World Rebirth‘s new island effectively retcons the purpose of Isla Sorna in The Lost World: Jurᴀssic Park by supplanting it. The Lost World’s retcon to Jurᴀssic Park was that Isla Sorna became where InGen cloned the dinosaurs, which were then brought to Isla Nublar for Jurᴀssic Park’s zoo. The Lost World‘s retcon undermined the scene in Jurᴀssic Park that showed the genetics lab in Isla Nublar, implying the dinosaurs were cloned and born on-site in Jurᴀssic Park.
It’s also possible that Jurᴀssic World Rebirth’s island was used mainly to test super predator dinosaurs.
Site C in Jurᴀssic World Rebirth retconned as InGen’s dinosaur research and testing facility could mean Isla Sorna is now where dinosaurs were brought for further evaluation before moving to Jurᴀssic Park. It’s also possible that Jurᴀssic World Rebirth‘s island was used mainly to test super predator dinosaurs, since Site C only seems to contain InGen’s ᴅᴇᴀᴅliest carnivorous creations.
Jurᴀssic World Rebirth’s New Island Doesn’t Make Sense
How Many Dinosaur Islands Did InGen Own, Anyway?
Jurᴀssic World Rebirth will have to justify why and how InGen owned three separate islands to breed and store cloned dinosaurs, and what, exactly, differentiates Site C from Isla Sorna. Another complication is Jurᴀssic World‘s reboot that InGen was acquired by Masrani Global Corporation, which funded and opened the Jurᴀssic World theme park. Did Masrani know about Site C, and if not, how is that possible?
After all, there was no mention whatsoever of a third dinosaur island in the three Jurᴀssic World films. However, this could also be justified by Jurᴀssic World Rebirth. If the island near Barbados contained dinosaurs too dangerous for Jurᴀssic 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 for Jurᴀssic World: Fallen Kingdom‘s dinosaur auction that subsequently let the prehistoric beasts loose on the world in Jurᴀssic World Dominion.
