Tyrannosaurs

Tyrannosaurs were among the most aggressive and largest theropod dinosaurs in North America and Asia, descended from early coleurosaurs no bigger than chickens. Tyrannosaurs ranged from the size of a large dog (3 meters) to the size of a mammoth (over 6 metres high and 13 meters long).

Below is a variety of the tyrannosaur family genera and tyrannosaur species seen in Jurassic Park and The Land Before Time.
