Overview

The Rex, or formally Tyrannosaurus (tye-RAN-uh-SAWR-us), is a huge, bulky predator that dominates virtually all of the island and is rivaled by few and surpassed by even fewer.

It was first added in  ARK: Survival Evolved on its early release.

Behavior

Highly aggressive, Tyrannosaurus will attack most living creatures in sight aside from other apex predators. They're extremely bulky, having nearly double the  Health of  Spino of the same level. They also possess surprisingly good  Stamina for their size, of which is also greater than that of any same-leveled  Spino. What Tyrannosauruses lack in attacking speed (when compared to a  Spinosaurus) they make up for in sheer  Health. Tyrannosaurus generally ignore mounted tamed animals and choose to attack wild animals instead, but will attack tamed mounted animals if they get too close. However if they see a helpless tame or dismounted  Human in the open, they will begin to attack.

Appearance

The Rex is an exceptionally large and often colorful theropod dinosaur. They can be found in a wide range of colors, ranging from brown, to greyish-purple and even dark red. They are covered in small, pebbly scales that are regularly interrupted by large osteoderms. Their underbelly, however, is smooth, generally tan, with small rectangular scales. Along their neck and back there is a large ridge of large bony scutes, and they have proportionately long legs that end in three thick, padded toes, each decorated with one large claw. They are quite long, but possess disproportionately small, yet thick, arms.
