Inside ‘Jurassic World’: Here’s the Freaky Real Dinosaur Indominus Rex Is Based On

The most ferocious predator in Jurassic World is a little bit frog, a dash of cuttlefish, a smidgen of snake, and heaping helpings of T. rex and Velociraptor. But the movie’s Indominus rex takes its visual cues from one of the strangest dinosaurs ever discovered.

“I started the process with a dinosaur called Therizinosaurus that has big grasping arms. That was the most important thing — the grasping arms and its color. It’s white,” paleontologist Jack Horner, who served as the scientific advisor on all four Jurassic films, tells Yahoo Movies.

Discovered in Mongolia’s Gobi Desert in 1948, Therizinosaurus was unlike any known dino. Its exaggerated claws were initially mistaken for turtle ribs. Eventually, paleontologists realized the appendages were indeed claws and gave the imposing beast, which stood over 30 feet and whose front limbs stretched up to 11 feet, a name that means “Scythe Lizard.”

But there’s one major difference between Therizinosaurus and Indominus: the former is actually a plant-eater that used its claws to rake up leaves, and secondarily for defense.

Of course, as Chris Pratt’s Owen Grady notes in Jurassic World, the fabricated Indominus “is not a dinosaur.”
