Isla Nublar Discovery

Verified Timeline

Lore & Background

The island's geography includes an inactive volcano and tropical climate, providing natural isolation from the mainland. In the first novel and film, the park failed to open after animals escaped, leading to the Costa Rican government declaring the area unsafe and napalming it in the book's narrative. However, the film series diverges here; the island remained intact through the Jurassic World trilogy. By the time of Jurassic World (2015), Masrani Global Corporation had successfully realized the theme park concept on Nublar following InGen's absorption. The island faced a second crisis during the Indominus rex incident, which saw dinosaurs overrun the facility again. Ultimately, in Jurassic World: Fallen Kingdom (2018), the island's volcano became active and erupted, destroying Isla Nublar and forcing an evacuation that scattered dinosaurs to various locations worldwide.

In Their Own Story

The narrative of Isla Nublar begins with its role as a secluded laboratory where InGen extracted ancient DNA from mosquitoes fossilized in amber. Scientists filled gaps in the genome using frog DNA before cloning dinosaurs on this remote island. The story shifts dramatically when containment systems fail, releasing predators into the wild and ending the park's operation. Years later, under Masrani Global Corporation, the island hosted a functioning theme park until the arrival of the genetically engineered Indominus rex caused chaos. The saga concluded with a catastrophic volcanic eruption in 2018, which destroyed the island's infrastructure and forced the relocation of surviving dinosaurs to the U.S. mainland and other global locations, effectively ending Nublar's existence as a contained sanctuary.

Reader's Guide

Visitors to the lore of Isla Nublar must note its specific geography: located 120 miles west of Costa Rica with an inactive volcano. In the films, real-world Hawaiian islands like Oahu and Kauai stood in for this fictional location, with additional filming on sound stages in California and Louisiana. The island's history is split between literary and cinematic timelines; while the book ends with a napalm strike by the government, the movies depict decades of survival and redevelopment. Key turning points include the 1993 failure under InGen, the successful opening of Jurassic World under Masrani Global, the Indominus rex incident, and the final destruction via volcanic eruption in 2018. The island's legacy is further complicated by promotional materials for Fallen Kingdom suggesting an ecosystem breakdown due to illegally-cloned animals introduced from Isla Sorna.

Did You Know?

• In the first novel, the Costa Rican government declared Isla Nublar unsafe and napalmed it, whereas the film series depicts the island surviving until its volcanic destruction in 2018.
• Isla Nublar is located exactly 120 miles (190 kilometres) west of Costa Rica in the source material.
• Jurassic World Rebirth was released on July 2, 2025, marking a new chapter in the franchise without director Colin Trevorrow's involvement.
• The name 'Isla Nublar' translates to 'Cloud Island' in Spanish, while its neighboring island Isla Sorna means 'Sarcasm Island'.
• Steven Spielberg returned as executive producer for every film after The Lost World, starting with Jurassic Park III (2001).

Franchise Origins and Evolution

The Jurassic Park franchise began when Universal Pictures and Amblin Entertainment purchased rights to Michael Crichton's novel in 1990, before its publication. The story centers on a disastrous attempt to create an animal theme park of de-extinct dinosaurs. Steven Spielberg's 1993 film adaptation was successful, receiving a theatrical 3D re-release in 2013 and being selected for preservation in the United States National Film Registry in 2018. Crichton wrote only one sequel novel, The Lost World (1995), followed by the 1997 film adaptation also directed by Spielberg. He did not write further sequels, though Spielberg returned as executive producer for subsequent films starting with Jurassic Park III (2001). A second trilogy began in 2015 with Jurassic World, followed by Fallen Kingdom (2018) and Dominion (2022), all co-written by Colin Trevorrow, who directed the first and third installments. The series continued with Jurassic World Rebirth, released on July 2, 2025, without Trevorrow.

Scientific Premise and Visual Realism

The franchise's premise involves cloning dinosaurs by extracting ancient DNA from mosquitoes that sucked dinosaur blood and became fossilized in amber. Scientists fill gaps in the genome using frog DNA to complete the sequence. The films primarily take place on fictional islands off Central America, though later entries show dinosaurs relocating globally. Visual recreation relies on animatronics and computer-generated imagery, with the first film praised for changing public perception of dinosaurs. However, the Jurassic World trilogy faced criticism for ignoring recent paleontological findings to maintain continuity with earlier films. To address this, Jurassic World Dominion (2022) expanded upon the concept of feathered dinosaurs first introduced in Jurassic Park III (2001). Within the story, characters explain scientific inaccuracies by attributing them to the animals being genetically engineered rather than perfect clones.

Corporate Entities and Rivalries

International Genetic Technologies, Inc. (InGen) is the fictional company responsible for cloning the dinosaurs. According to the novels, InGen is based in Palo Alto, California, with one location in Europe, though most research occurred on Isla Sorna and Isla Nublar. The first film emphasizes the Jurassic Park brand, though the InGen name appears on computer screens and helicopters without being spoken. By the time of Jurassic World, Masrani Global Corporation had subsidized InGen and its intellectual property. After InGen went defunct, ParkerGenix obtained its files for pharmaceutical agendas in Jurassic World Rebirth. A rival entity, Biosyn Corporation (or Biosyn Genetics), is based in Cupertino, California. Originally an antagonist in the novels engaging in industrial espionage, Biosyn makes its film debut in Jurassic World Dominion (2022). Under CEO Lewis Dodgson, Biosyn houses captured dinosaurs in Italy and attempts to capture Maisie Lockwood before their plot involving giant locusts is exposed.

Cultural Impact and Expanded Media

Jurassic Park is one of the highest-grossing media franchises of all time, with the film series earning over $6 billion at the worldwide box office as of 2022. The original Jurassic Park was the first to surpass $1 billion during its 2013 re-release, a feat followed by each installment in the Jurassic World trilogy. Beyond films, numerous video games and comic books have been created since 1993, alongside water rides at various Universal Studios theme parks. Lego produced animated projects including the miniseries Legend of Isla Nublar (2019). DreamWorks Animation released two Netflix series: Jurassic World Camp Cretaceous (2020–2022) and Jurassic World: Chaos Theory (2024–2025), both set during the Jurassic World trilogy.
