Trex--Hunter or scavenger?

 

I remember this debate from a few years ago, and for some reason, it keeps popping back up.

Was Tyrannosaurs Rex, the greatest meat eater of all time, an active hunter or scavenger?

Seems pretty obvious to me that it was an active hunter.  Look at the teeth! Granted, it probably stopped off to eat something it found that was dead and not too rotten.  Still, the idea that T-rex was a scavenger is ridiculous. 

T-rex teeth or their crowns, have been found embedded in the bones of other dinosaurs, usually plant-eating herbivores, and the bones have healed.  So, said duckbill was bitten by T-rex, escaped, and the bite healed.  Remember, not every hunt is successful.  Even the Predator did not win every time!

T-rex vs Predator.....

...Now there is a debate we can start!
