Jurassic Park Wiki

Mantah Corp Island is a privately-owned, uninhabited island in the Gulf of Fernandez utilized by Mantah Corp as a research and testing facility for de-extinction and genetic engineering. This is probably not its original name. The island is located to the east of Isla Nublar, closer to the Costa Rican mainland.

Mantah Corp Island makes its appearance in Jurassic World: Camp Cretaceous Season 4, where it is used by Mantah Corp and its president Daniel Kon. In the final season, the campers known as the "Nublar Six", finally defeated the Mantah Corp and saved the dinosaurs, tricking Daniel into believing the island was exploding. After Daniel's arrest, the children turned Mantah Corp's island into a secret dinosaur sanctuary as their "secret island", with only a few knowing of the island's continued existence.

In Jurassic World: Chaos Theory, its revealed that the island's existence was eventually discovered at some point after the events at Lockwood Manor and the dinosaurs were taken by the DPW. However, the Nublar Six and their allies managed to smuggle Bumpy off before the Mantah Corp Island investigation was finished.


Mantah Corp Island has five biomes built onto it; Desert, Redwood Forest, Tropical Rainforest/Jungle, Snow/Tundra, and Tropical Swamp. All interconnecting these areas is a facility that has multiple floors and halls, including a viewing panel on the Forest Biome, a medbay (where a Stegosaurus was present), and a nursery, where a baby Brachiosaurus (Firecracker), two baby Spinoceratops (Angel and Rebel), and a Ceratosaurus were present. The main control compound and many of the other operations buildings are located on the surface of the Tropical Rainforest/Jungle biome, while the medical bay is located directly below the Tropical Swamp biome. A field research office is located within the Redwood Forest biome.

The Forest biome was a large forest to represent Isla Sorna for the Redwood forest for the T. rex to have some similar behavior to stay calm. It has food machines that feed the tyrannosaurs. Mae warns the kids as the T. rexes could be much more aggressive. Mae's home is located underneath a waterfall as a cave.

The Desert biome has hot temperatures that can be increased by employees for rising temperatures. The biome has a canyon that has pipes to release water for animals that lived there. They were cactus plants for flora.

The Snow biome has low temperatures and was where Pierce was sent by Kash to see how long it could last there.

The Swamp biome was the most recent biome that mimicked the wetlands, with mist present, and the water around the trees.

Each biome is covered by a massive dome that can be used to alter the climate in the biome, the domes are also covered in screens to replicate different times of day.

There are no species known to be in the Snow/Tundra Biome permanently, although the hybrids Angel and Rebel were suited for the environment, as Pierce the Kentrosaurus happened to enter from the Desert Biome.

The newer and yellow-green Velociraptor, Smilodon, Nothosaurus, Spinoceratops, and Kentrosaurus were confirmed to be cloned by Mantah Corp, with some Tyrannosaurus rex, Brachiosaurus, Dilophosaurus, Ceratosaurus, Stegosaurus, Pteranodons, and Spinosaurus being from Isla Sorna and Compsognathus, Ankylosaurus, Carnotaurus, Baryonyx, and Dimorphodon being from Isla Nublar.

People Involved[]


These biomes were made so that Kash would use them to have dinosaurs fight as a means of advancing Mantah Corp, evidenced by his contact with the investors who were coming. Kash also used Mae's research to control dinosaurs via chips implanted in their heads.



  • It's unknown what happened to the Stegosaurus or Ceratosaurus on the island. It's possibly they are still somewhere in the underground tunnels or they were placed in the Jungle Biome.
  • The fate of Limbo and the Dimorphodon from Season 5 remains unknown. It is possible the Dimorphodon is still flying in the Redwood Forest Biome or was taken to the Med Bay for treatment. Same can be assumed for Limbo if he survived Big Eatie's attack.
  • Asset 87, the Spinosaurus was first placed in the desert biome as a test to see how long it could have survived in the heat. In Battle Lines, the Spinosaurus was brought in the Redwood forest biome for some time during the investor presentation and again placed in the desert biome. During the final battles of Season 5, it was brought to the Redwood Forest Biome and then to the Jungle Biome, where it was eventually freed by Big Eatie. It is unknown if the Spinosaurus is still residing in the Rainforest Biome or if it was returned to the Desert Biome.
  • With the confirmation that the island was investigated and shut down sometime between 2018 and 2022, it is unknown exactly what happened to the animals on the island. Only Bumpy and Big Eatie’s fates are known with Bumpy having been taken to Sammy’s ranch and Big Eatie being captured by the Department of Prehistoric Wildlife with both being planned to be sold to unknown buyers but escaping into the wilds of America.
