A recent dinosaur discovery was made when a Tyrannosaurus tooth was found embedded in a hadrosaur tail vertebra that shows the hadrosaur was actively attacked. I was wanting to know if any new information is available, other than implications of the attack has on the debate on tyrannosaur feeding habits?
