Tyrannosaurus rex is one of the largest therapods and eats large quantities of meat from any source.
They are normally solitary, and hunt both large and small prey over a wide territory. They will happily coexist with a good number of other dinosaur species, although maybe not to their satisfaction!
T. rex prefers large areas of open grassland for its territory.

Tyrannosaurus rex is probably the most familiar dinosaur in history. Its name means "tyrant lizard king' and to many it represents the ultimate predator. This magnificent animal has long been at the heart of dinosaur attractions.
This bipedal carnivore is known for its massive heart with what is theorized as one of the strongest bites to have ever existed on land.


Tyrannosaurus rex fossils have been found across the once island continent of Laramidia - now western North America.
Teeth were the first fossil find in 1874 near Golden in Colorado. The largest skeleton find so far was by Sue Henrickson at the Hell Creek Formation in South Dakota.


Tyrannosaurus rex ranged across a number of different ecosystems. These vary between island and coastal subtropical regions, and semi-arid plains. To the north it is considered the dominant predator, but to the south Alamosaurus dominated.


  • The T. rex in Jurassic World: Evolution is noticeably larger than its real life or film canon counterparts, and was even larger than Spinosaurus and Giganotosaurus.
    • This has since been somewhat rectified in the 1.4 update[1], which downsized the T. rex and increased the sizes of the Spinosaurus and Giganotosaurus.
  • The T. rex has a unique music cue when being released from the hatchery, using themes from the opening scene and T. rex chase scene from the first Jurassic Park film.
  • The Wetland pattern can only be unlocked once the player creates a 5 star park on Isla Pena on Jurassic difficulty.
