Now that Jurassic Park IV is finally back on track after a short delay, more details about the story and the concept are starting to come forward. Be warned, there will be spoilers listed below, so read on at your own risk.

An unidentified source close to the production confirms that the story returns to Isla Nublar, the setting of the original Jurassic Park, which has been turned into an actual theme park, as first envisioned by Richard Attenborough's John Hammond, and the film will be shot in 3D.

Here is the story description as it appears on Joblo:

"Jurassic Park IV, set in present day Isla Nublar, is now an actual theme park, as originally intended by John Hammond in the first film. It garners 10 million visitors per year and is completely safe - until it's not. The park itself is described as very Sea World-esque and includes an area called the Isla Nublar Lagoon. That means underwater dino's for the first time. No indication of what kind, but there is concept art showing one of the aquatic dinos, as part of a show, jumping out of a lagoon and eating a strung up great white shark like it was a fish for a dolphin at sea world.

As part of a show, you ask? That's right, folks, this will feature "tamed" dinos. The usually menacing Velociraptors (which will finally be muzzled, along with the T-Rex, until they're not) will actually be used to help fight the threat, which begins in the form of a new dinosaur, not seen in any of the previous films (and not disclosed to us) who shows to be much smarter than originally thought and is the main cause of havoc breaking out at the park.

To sum it all up, Jurassic Park IV will take place back on Isla Nublar with a fully operational dinosaur theme park that's both prosperous and safe, until a new dinosaur figures out a way to wreak havoc, causing the use of the now tamed Velociraptors and T-Rex as a means to fighting the threat."

Back in April, paleontologist Jack Horner, who is serving as a dinosaur consultant, revealed that this sequel features a dinosaur that has never been seen before. Director Colin Trevorrow described it as a "new dinosaur" that will make us "keep the lights on after you see this movie." The director also previously teased the Isla Nublar setting with a location scouting photo. These story details have not been confirmed by the studio, and we don't expect them to be, but, either way, these details do offer some intriguing possibilities.

Just remember Colin Trevorrow's goal in making the movie.
