Jurassic World: What Happened To Site B, Isla Sorna
The Jurassic World movies have forgotten about Isla Sorna, the second island of dinosaurs in the original trilogy. Here's what became of Site B.
Here's what happened to Jurassic Park's island of Isla Sorna, also known as Site B. After Jurassic World soft rebooted the Jurassic franchise in 2015, there has been no mention of the second island of dinosaurs that was the setting of 1997's The Lost World: Jurassic Park and 2001's Jurassic Park III. Isla Sorna was originally the factory floor of InGen, the biotech company owned by billionaire John Hammond (Richard Attenborough), where the dinosaurs were cloned and bred before being transported to Jurassic Park on Isla Nublar, 87 miles east of Isla Sorna.
In The Lost World, Hammond sent Dr. Ian Malcolm (Jeff Goldblum) to lead a team to Isla Sorna in order to document the dinosaurs and gain public support for Site B to be isolated as a natural preserve. Meanwhile, InGen's new CEO and Hammond's nephew Peter Ludlow (Arliss Howard) sent a mercenary team to Isla Sorna to capture the dinosaurs for display in Jurassic Park: San Diego. The incident led to both teams getting decimated by the Tyrannosaurs Rexes and Velociraptors on the island. Although a T-rex was captured and brought to the mainland, it escaped and rampaged through downtown San Diego. After the T-rex was brought back to Isla Sorna, the island was declared a restricted zone and the 1997 Gene Guard Act protected the dinosaurs' rights and prevented more cloning. However, InGen continued to illegally clone dinosaurs, including dangerous new species like the Spinosaurus, which Dr. Alan Grant (Sam Neill) faced in Jurassic Park III when he went to Isla Sorna to rescue the child of a wealthy couple who was trapped in Site B.
Jurassic World, set 14 years after Jurassic Park III and 22 years after Steven Spielberg's original blockbuster, revealed that the Masrani Global Corporation bought InGen, resumed its dinosaur cloning and successfully opened John Hammond's theme park. Masrani even brought back Dr. Henry Wu (B.D. Wong), Jurassic Park's geneticist, to oversee the creation of new dinosaurs. But Isla Sorna's fate hasn't been mentioned in Jurassic World or in the 2018 sequel, Jurassic World: Fallen Kingdom. Instead, the clues to what happened to Site B can be found in a movie tie-in website created for Jurassic World: Fallen Kingdom's Dinosaur Protection Group headed by Claire Dearing (Bryce Dallas Howard). Essentially, Isla Sorna is no more.
When InGen abandoned Site B after the incident seen in Jurassic Park, the dinosaurs were let loose upon the island. Instead of succumbing to the lysine deficiency that they were bred with, the animals thrived instead and developed a natural order. However, in 1998, InGen returned to Site B and conducted illegal cloning in defiance of the Gene Guard Act and they introduced the Spinosaurus into the ecosystem. The Spinosaurus replaced the T-rex as the island's apex predator and unbalanced the natural order. When Masrani bought InGen and opened Jurassic World, they took the remaining living dinosaurs from Site B and transported them to populate their new park on Isla Nublar. Isla Sorna was then abandoned and became a dead zone.
Ironically, the eruption of Mt. Sibo in Jurassic World: Fallen Kingdom destroyed Isla Nublar, killing the dinosaurs that weren't captured and transported to the United States to be sold in an illegal dinosaur auction. The dinosaurs were set free by Owen Grady (Chris Pratt), Claire Dearing, and Maisie Lockhart (Isabella Sermon) and are now loose upon the world. But, since the abandoned island of Isla Sorna still exists, maybe the answer to the global crisis in the upcoming Jurassic World: Dominion will be to capture the dinosaurs and bring them back to Site B where they can live in peace once again.
