Fighting in Tyrannosaurs: Evidence from scars on bones

Tyrannosaurs were the largest predators in dinosaur dominated ecosystems across North America and Asia during the Late Cretaceous. Due in part to their size and geographic/temporal occurrence, tyrannosaurs have one of the best fossil records of theropod dinosaurs. An intriguing aspect of these fossils is the common occurrence of healed (or partially healed) bone scars, caused by tooth marks, preserved on their skulls. 

This talk is a “what we know, and how we know it” approach, documenting the occurrence, frequency, and morphology of these bite marks through a growth series, and across multiple tyrannosaur species.
