Physical Characteristics: Two-footed dinosaur, with a very big head with respect to its body, and about 50 sharp teeth, dagger-shaped, with a length of about 15 cm.

Extended Description: Tyrannosaurus have been the greatest carnivorous dinosaurs ever existed. One hypothesis is that they were too heavy to actively hunt, and ate only remains; on the other hand studies suggest that they could have been very good, fast and active predators. The position of its tail during locomotion, whether it was dragged or not, is also ambiguous.
