[N] 2004 Bitemark could help resolve a dispute about Tyrannosaurus rex
A CT scan of bones from a hadrosaur dinosaur discovered north op Powell in northwest Wyoming in the fall of 2000 gave researchers a detailed look at a bite mark in the rib of this duckbilled herbivore and could help resolve a dispute about Tyrannosaurus rex. The scientists theorize a T. rex bit the hadrosaur -- and the hadrosaur survived. That\\\'s significant because it is often thought that T. rex was a scavenger that did not hunt live prey. According to Wegweiser something was trying to make a meal out of this hadrosaur, trough the Ct scan a virtually three-dimensional model the tooth that did the biting could be created. The tooth was large and probably done by a large theropod. \\\" This tooth comparison could give us solid evidence of a Tyrannosaurus rex attack,\\\'\\\' said Wegweiser. ``If it\\\'s proven that it\\\'s not a Tyrannosaurus rex, then we have an entirely new dinosaur.
