Common Name: Tyrannosaurus Rex a.k.a. T Rex.

Temporal Range: 70 to 66 million years ago.

Diet: Tyrannosaurus Rex was a large carnivorous dinosaur. T Rex was so big there were only a couple of animals that tyrannosaurus didn’t eat. Extremely large dinosaurs like the barosaurus is one example. Not many animals were safe from tyrannosaurus including itself. There have been a lot of bones found in the fossilized stomachs of tyrannosaurs that were from the skeletons of other T Rex.

Height: 15 to 20 feet.

Length: Up to 39 ft in length, in other words about the size of a bus, however; contrary to popular belief T Rex was not the biggest land based carnivore ever. That distinction goes to the spinosaurus which was 20 to 30 feet longer than an average tyrannosaur.

Weight: 12 to 13 tons.

Speed: Roughly 17 mph.

Habitat: Forests and swamps.

Defense: T Rex was prey for only one animal, T Rex itself.

Life span: Around 30 years in this amount of time t rex may have grown five pounds a day.

Behaviour: T Rex took care of their young until they were able to take care of themselves.
