For a century, the towering Tyrannosaurus Rex has been regarded as a savage killer marauding unchallenged across the later dinosaur era. But a new exhibition at London's Natural History Museum asks whether the monster meat-eater was instead a lumbering bully which lived on rotting corpses or used its bulk to rob smaller dinosaurs of their prey. "I believe it was a scavenger pure and simple because I can't find any evidence to support the theory that it was a predator," palaeontologist Jack Horner said at the opening on Thursday of "T-Rex - the killer question." Horner, the inspiration for scientist Alan Grant -- played by Sam Neill -- in Steven Spielberg's "Jurassic Park," said the lumbering giant was too slow, its arms too small and its sight too poor to catch anything moving. On the other hand -- like a vulture -- the part of its brain dedicated to smell was huge and its giant jaws were bone crushers not flesh cutters.

"Everything says this dinosaur lived on dead meat. Even statistically we find that plant-eating dinosaurs were far more common than predators, and T-Rex is the second most common dinosaur," said Horner from Montana's Museum of the Rockies.

I've heard the theories about T-Rex bieng a scavenger before. Still a big, menacing animal though, and folks do tend to steer clear of vultures.

I punched a vulture in the beak once. But, to be fair to the vulture, he was eating my liver at the time.

Yep I heard on one of the Discovery Channels that T-rex was more likely a scavenger than a hunter.
