If you thought T-Rex was the scariest dinosaur, think again. Paleontologist Dr. Phillip Currie believes he has found a six-ton flesh-eating dinosaur that hunted its prey in packs. Until recently there was little evidence to support Currie's ideas. That's all changed with his discoveries in two mass dinosaur graves. One site lay untouched for decade until Currie himself tracked it down and the other contains the bones of a giant new species of dinosaur.
