All three "Jurassic Park" films have followed the same general format. Humans enter a place full of dinosaurs. Dinosaurs hungry; attempt repeatedly to eat humans. Humans who remain uneaten book it, leaving dinosaur territory until a sequel is greenlit.

But "Jurassic World" might turn that whole formula on its head. Because there's a new rumor floating around, and it involves a lot more than humans running from dinosaurs. This time, we might have good dino vs. bad dino action.

The rumors come from Enstars, who claim two things about the upcoming sequel. One, that it will prominently feature aquatic dinosaurs (something that's been stated many times in previous rumors, and even shown in a leaked piece of promotional material.

And two, that star Chris Pratt will head up a new anti-dinosaur tactic: sending hero dinosaurs to fight against a newer, stronger breed, the (totally fictional) Diabolus Rex.

Fashion & Style back up this rumor, claiming that an early leaked description of the first "Jurassic World" trailer contains references to a devastatingly powerful mystery dino, and hints at Chris Pratt training velociraptors for good.

Jurassicworld.org had a full description of the trailer up (the leaked one Fashino & Style is referencing), but it was taken down at the request of NBC/Universal, which may point to it being legit. If that's the case, "Jurassic World" will be a dinosaur movie (or at least, a "Jurassic Park" movie) unlike one we've ever seen before, presumably with plenty of dinosaur action to back it up.

Because we can all admit, that after seeing the Spinosaurs vs. T-Rex fight in "Jurassic Park III," more dinosaur fighting is something that everyone wants to see.

Everyone.

Check back soon for the latest news on "Jurassic World," and any updates on when that first trailer will show up.
