Tyrannosaurus rex is an adoptable animal in Zoo Tycoon and Zoo Tycoon 2 expansion packs. The most famous dinosaurs, it is a type of theropod dinosaur native to North America. This animal was up to 40 feet long and 14 feet tall. It had the highest bite force of any known land animal. All of its senses were exceptionally high, but its eyesight and smell in particular ranked among the greatest of any animal. Tyrannosaurus had a proportionately miniscule brain and was probably a social animal. Juvenile Tyrannosaurus were proportionately skinnier and more lightweight than adults, and their skulls were lengthened. Juveniles were likely very fast runners.

Zoo TycoonEdit

Kronus the Tyrannosaurus Rex

The T. rex as seen in Zoo Tycoon: Dinosaur Digs.

In Zoo Tycoon: Dinosaur Digs, T. rex is the one of the strongest predators in the game, and will eat any living thing, including all other dinosaurs besides their own kind. Its favorite foliage is the Monkey puzzle.

It is hard to keep a T. rex in this game because it needs a high amount of happiness to breed. Its main biome is the grassland but it needs large amounts of gray stone and it costs $6,500 for one T. rex. This biome is also more accurate than ZT2's. The original version turned out to be less accurate than the ZT2 version, but the eggs and babies were inaccurately enormous. The babies were bigger than a human being, when in fact they would be about the size of a soccer ball.

Zoo Tycoon 2Edit


Zoo Tycoon 2 Extinct Animals T. rex

The Tyrannosaurus in Zoo Tycoon 2 are smaller and less powerful compared to their Dinosaur Digs counterpart. However, they cost $80,000; more than ten times that of the original. Tyrannosaurus Rex is one of the ten animals that can rampage in Zoo Tycoon 2: Extinct Animals. You need 5 stars in order to purchase the T. rex. In Zoo Tycoon 2, the female is much larger than the male, and is darker in color. The tropical rainforest is it's main biome, but it will cope with grassland.

The adults are a bit smaller than actual size. They are comparable in size to the juveniles from the first game. Also, it is believed that juvenile Tyrannosaurs had a downy covering like baby birds, which the juveniles in both ZT1 and ZT2 lack. The juveniles are more accurately-sized than in Dinosaur Digs. T. rex is the star of the campaign game called The Dinosaur Zoo. Strangely, males, although the females are bigger, can kill the females.The stance of the animal is strangely upright and has been panned by most of the community for being unrealistic.


  • In Zoo Tycoon, unlike all other theropods, Tyrannosaurus rex is the only theropod that prefers cliffs or hills. Coelophysis tolerates them to a degree too.
  • Paleontologist James Farlow calculated the number of lawyers a grown Tyrannosaurus had to eat (based on a scene from the movie Jurassic Park, in which a lawyer became T. rex fodder) to stay alive. Taken an average weight of 68 kilograms, 292 lawyers would be needed to keep one T. rex happy for a year!
  • The Tyrannosaurus roar in the first game is taken from the Tyrannosaurus the Capcom video game Dino Crisis.
