Tyrannosaurus rex
Hands-down this is the most popular dinosaur of all time. Tyrannosaurus rex was the largest carnivore in it's environment and would have preyed upon the giant duck-billed hadrosaurs and horned-faced ceratopsians which were it's contemporaries. Fossil evidence shows that this ferocious animal was likely an opportunistic carnivore, which would hunt prey as an apex predator as well as scavenging for it's meals. Research into the bite force of this animal shows that it's jaws and giant teeth were designed for crushing through large bones and thick flesh.
