摘要: Trace marks on the bones of non-avian dinosaurs may relate to feeding by large carnivores or as a result combat. Here cranium and mandible specimen Daspletosaurus are described that show numerous premortem injuries with evidence healing these inferred primarily intraspecific In addition, postmortem damage is indicative late stage carcass consumption taphonomic context suggests this was scavenging. These bites were delivered bodied tyrannosaurid theropod have been second Daspletosaurus, thus would be an additional record cannibalism.
