This is the key question we hope to answer with this study. This project is to fund research into a skull of the carnivorous dinosaur Daspletosaurus (a close relative of Tyrannosaurus) which shows traces of biting from another, large carnivore, most likely another Daspletosaurus. Analysis of this exciting specimen will reveal which bite where made, where and how on the skull, and detailed comparisons to the skulls and teeth of other carnivorous dinosaurs from the area will allow the identity of the feeding animal. Study of the pattern of the bites and breaks can reveal how these bites were applied and thus how the scavenging animal had fed.
