Meet the Dino That Inspired 'Jurassic World's' Indominus Rex

Jurassic World invented the Indominous rex dinosaur and the whole planet seems thrilled they did. So what real dinosaur did the movie-makers use to design I-rex? Check out Therizinosaurus. That's who the filmmakers say was the basis of the Indominous rex.

Those claws are so long it looks like Edward Scissorhands. 'Theri,' as we'll call him, lived in the Cretaceous Period, which was 145 through 66 million years ago. And its fossils were first found in present day Mongolia.

Jurassic World set a record for the biggest opening weekend ever and is expected to be the fastest movie to ever bring in a billion dollars, in just 13 days. Meaning, yeah, the Therizinosaurus-based Indominous rex was successful so yeah, I'm sure there will be another one. So someone better be at the Natural History Museum doing their homework right now.
