Rare Evidence Of Dinosaur Cannibalism: Meat-Eater Tooth Found In Gorgosaurus 
Jawbone 


ScienceDaily (Oct. 7, 2009) â University of Alberta researcher Phil Bell has 
found 70 million year old evidence of dinosaur cannibalism. The jawbone of what 
appears to be a Gorgosaurus was found in 1996 in southern Alberta. A technician 
at the Royal Tyrell Museum found something unusual embedded in the jaw. It was 
the tip of a tooth from another meat-eating dinosaur. 

Bell, a paleontology PhD candidate, says discovery of the tooth shows that a 
fight between two dinosaurs definitely took place. "The wound showed no signs 
of healing so we know the dinosaur died soon after it was inflicted." Bell says 
that leaves two possible storylines. "Either the attacker fought, killed and 
ate this dinosaur, or the victim was already dead." Either way, if the attacker 
and the victim were the same species, Bell has a rare case of dinosaur 
cannibalism......
