Narrator: So for that moment, the scene uses both a CG head and window smash. John's finalized Giga head was 3D scanned to create the CG look. But these shots returned to the Giga puppet that was moving through an already-broken window on set.

When the Giga closes its eye after Bryce Dallas Howard stuns it, the servos powering this eyeball and eyelid were preprogrammed as one movement.

KO THE GIGA: even a low level giga has a lot of torpor and it drops fast so keep shooting no matter what. It’s recommended for a tribe-mate to help you. Notice how the Giganotosaurus' tongue bounces when it opens its mouth, or how its skin reacts when it roars. Narrator: The animatronic's facial movements were particularly crucial when interacting with the cast. The team had to link these servos to move several parts at the same time.

By placing rotational servos in the anatomically correct areas, the head could twist, pivot, and roll.Coria, R. A.; Sagado, L. (1994).

Across five films, the Jurassic series has so far featured a whole host of gigantic, fearsome prehistoric beasts. First up, we had the T-Rex in Jurassic Park – and then two of them in The Lost World. Jurassic Park III gave us the Spinosaurus. Then, in Jurassic World we met the genetic hybrid Indominus Rex, as well as the aquatic Mosasaur, with the Indoraptor to follow in Fallen Kingdom. Now, as we approach the long-awaited release of Jurassic World Dominion, get ready to meet a major new dinosaur who’ll be terrorising our heroes this time around – one who lives up to that mandate given by Claire Dearing in the first World: ‘Bigger. Scarier. More teeth.’ It’s called the Giganotosaurus – but for short, it’s known as the ‘Giga’. a b Holtz, T. R. (2011). "Dinosaurs: The Most Complete, Up-to-Date Encyclopedia for Dinosaur Lovers of All Ages, Winter 2011 Appendix" (PDF) . Retrieved January 13, 2012. Both predators’ bites are vicious in different ways. T. rex can deliver the most skull-crushing of chomps, while Giganotosaurus’ bite leverages sharp, blade-like teeth to slash its prey’s flesh.

The U-shaped groove along the root shaft of the tooth is where the replacement tooth would have been growing. Independent Picture Service/Universal Images Group via Getty Images Holtz agrees that it could be any dinosaur’s game, despite admitting professional and personal bias toward tyrannosaurs (when he was 3, he wanted to grow up to be one). “Both of them are big predators adapted to killing very large prey,” he says. “If either of them managed to get a good bite onto the other one first, they’re probably going to win.” What’s in a bite?
