In Dominion, which opened last weekend, a Therizinosaurus and a Tyrannosaurus rex team up to kill the ultimate bad dino, a Giganotosaurus. In the epic battle scene toward the end of the film, it seemed all might be lost after the T. rex appeared to be killed.

Spinosaurus Spinosaurus Spinosaurus gets their one and only appearance as a "Big Bad" dino in Jurassic Park III. Agile, mean and very determined, it's a worthy nemesis for humans in the closing film of the Jurassic Park trilogy.

The Giganotosaurus is the strongest dinosaur in Jurassic World .

Therizinosaurus The Therizinosaurus' blindness also serves as a narrative device for Jurassic World Dominion's final fight. Only when the Giga is about to overpower the T-Rex, the Therizinosaurus fatefully enters the battleground and starts attacking the Giga.

Tyrannosaurus rex The “king of the tyrant lizards” will always be one of the scariest and deadliest dinosaurs around with a bite force three times that of a great white shark – making it the strongest bite force of any land animal that has ever lived.

Jurassic World Dominion's long-clawed Therizinosaurus presumably has cataract in its eyes, which explains why it does not spot Claire hanging from the tree. To ensure its survival in the wild, the Therizinosaurus heavily depends on its hearing and ruthlessly eradicates everything it perceives as a potential threat.

Therizinosaurus is one of the most aggressive herbivorous animals ever witnessed by human eyes. A perfect blend of size, power and speed, it can effortlessly take down or otherwise repel many dinosaurs in short order.

Most scientists agree that the Spinosaurus is the largest land predator, bigger than both the T-Rex and Giganotosaurus. According to paleontologists who studied a partial skeleton of a Spinosaurus, the dinosaur was roughly 60 feet long, with the sail on its back being about seven feet tall.

Tyrannosaurus Rex Of course, the Tyrannosaurus Rex had the strength to be called “the strongest dinosaur”. Rex, a Latin word meaning “King”, reflects the kingly status it achieved due to its imposing characteristics.

Either way, this was a big animal and an apex predator in its habitat. Prognathodon has been estimated to reach lengths in excess of 33 feet, and the biggest Mosasaurus species got to be even larger - around 59 feet, or nearly 20 feet longer than the biggest T. rex.
