Tiny Actor's Awesome Options -- 'Iron Man' or 'Jurassic World'

EXCLUSIVE

"Jurassic World" is about to do battle with "Iron Man" ... and the victor gets a 13-year-old kid.

Ty Simkins is a hot pint-sized commodity in Hollywood. He starred alongside Robert Downey Jr. in "Iron Man 3" ... and he's also set to star in the upcoming dino flick, "Jurassic World."

Ty's "Jurassic" paycheck would dino-soar him to new heights ... $200K base -- according to his contract which was filed with the court. He'll make another $125K if the flick kills. And the sequels would score him $400K minimum for #2 and double that for #3.

Here's the problem .... Marvel -- which produces "Iron Man" -- has locked the kid up for a long time. It has first dibs on 3 sequels ... which could put Ty way past Bar Mitzvah age before he could do "Jurassic."

We're guessing the kid is gonna be iron deficient.
