Tooth is 'smoking gun' evidence that Tyrannosaurus rex was hunter, killer

So, it may come as a shock that for more than a century some paleontologists have argued that T. rex was a scavenger, not a true predator -- more like a vulture than a lion. Indeed, a lack of definitive fossil proof of predation in the famous theropod has stirred controversy among scientists -- until now. Researchers have unearthed "smoking gun" physical proof that T. rex was indeed a predator, hunter and killer.
