“This is Isla Sorna. You've got a larger land mass to deal with on this island. More opportunities for success... And-uh of course for the unexpected. Which shouldn't be unexpected, but you know, it just always is.”
- - Dr. Ian Malcolm
Isla Sorna, also known as Site B, is the largest island in the Muertes Archipelago, considered to be the "factory floor" of dinosaur breeding. It is hit often by storms, but its large size provides benefit to the player to add many dinosaurs.
In the mid-1980s, Isla Sorna, together with Isla Nublar and the other islands of the Muertes Archipelago, were sold to InGen by the Costa Rican government in a 99-year lease over the islands. The island was purposed into research facility and factory floor on which dinosaurs were initially cloned and matured, before being transported to the Jurassic Park facility on Nublar. The first dinosaur cloned by InGen, a Velociraptor, was successfully bred on Sorna in 1986, while the first adult specimens were shipped from Sorna to Nublar in 1990.
Soon after the Isla Nublar Incident in 1993, Isla Sorna was hit by the powerful Hurricane Clarissa, forcing InGen to abandon the island. In the aftermath, a stable ecosystem of the island's dinosaurs began to form, with dozens of species flourishing in regions of the expansive island habitat. Eager to ensure the planet's isolation, InGen's ailing CEO John Hammond dispatched a team led by Dr. Ian Malcolm to document the island's inhabitants, in an effort to raise public support for the island to be designated as a restricted nature preserve.
In 1997, a young British girl was attacked and injured when her family happened upon the island, prompting Hammond's nephew, Peter Ludlow, to wrest control of InGen from him and begin a mission to capture the island's dinosaurs and bring them to a new park under construction in San Diego. Hammond's team soon came into conflict with Ludlow's hunters, setting dozens of dinosaurs free, though marooning both groups on the island. Although both groups eventually joined together to survive the island's perilous dangers, they became separated when a pair of Tyrannosaurus attacked their camp. Despite numerous fatalities, the male Tyrannosaurus was sedated and brought back to San Diego, where it promptly escaped onto the city streets before being caught and transported back to the island alongside its offspring.
After the San Diego Incident, the United States Congress passed the Gene Guard Act, which restricted any further access to Isla Sorna and the other islands owned by InGen, as well as banned any further cloning of extinct animals. Nevertheless, within one hundred days of Masrani Global's purchase of InGen, a team of InGen scientists travelled to Sorna and began experimenting on several new species of dinosaur, including Ankylosaurus, Ceratosaurus, Corythosaurus and Spinosaurus. These animals were abandoned on Isla Sorna in 1999, and encountered by the survivors of a plane crash on the island in 2001. Reports of these animals were subsequently buried by "bribed officials" after the incident.
The introduction of these illegally cloned dinosaurs, specifically a super-predatory Spinosaurus, had a devastating impact on Isla Sorna's ecosystem, causing a "considerable and mystifying drop in population", which remained unexplained until leaked documents in 2015 revealed the illegal cloning activities of the late 1990s. In 2004, in an effort to save the island's inhabitants from extinction, Simon Masrani had Isla Sorna's surviving dinosaurs shipped to Isla Nublar, where they would eventually be exhibited alongside recently cloned animals in Jurassic World. As of 2018, Isla Sorna is reportedly abandoned, though it remains restricted.
“Isla Sorna presents the ultimate challenge for your operations in the Five Deaths. This was once a vast InGen facility, but is now long-abandoned. Refashion the wild landscape and ruined infrastructure into the greatest facility yet.”
- - In-game description The final island unlocked in Jurassic World Evolution, Isla Sorna provides an entirely different challenge in comparison to the other islands of the Muertes Archipelago. When players arrive on the island, it is a "lost world", where dinosaurs roam freely without fences. Players can then decide whether to round the dinosaurs up and sell them, or create a facility to house them on the island.
