摘要: Ecological and behavioral aspects of dinosaur research are receiving increasing attention. Tooth‐marked bones have been studied for many years, provided important information on the feeding behaviour mammalian carnivores. Similarly, theropod tooth marks can provide clues to predator/prey interaction in ancient ecosystems. A study 1000 from Dinosaur Park Formation (Judith River Group, Upper Cretaceous) Alberta, Canada showed a relatively high percentage tooth‐marked hadrosaurid (14%), whereas only 5% ceratopsid marks, 2% tyrannosaurid bones.
