here is some info on the all powerful t-rex:

Period: Late Cretaceous
One of the largest-ever flesh-eating land animals, Tyrannosaurus is also the most famous. For example, it has been featured in more movies than any other single dinosaur. Tyrannosaurus had a huge skull with powerful jaws lined with 7-inch (18-cm) serrated teeth. Contrary to earlier conceptions of sluggish mobility, Tyrannosaurus is now thought by some to have been capable of bursts of up to 30 mph (48 km/h). In contrast to its massive legs, Tyrannosaurus had relatively short, small arms. Although they seem vestigal and useless, they were powerful enough to lift over 450 pounds (270 kg). Tyrannosaurus was found in North America and Asia. The most famous species is Tyrannosaurus rex from North America; Tyrannosaurus bataar from Asia was formerly known as Tarbosaurus.
