Bite marks on the frill of a juvenile Centrosaurus from the Late Cretaceous Dinosaur Provincial Park Formation, Alberta, Canada

A rare fossil discovery reveals bite marks on the frill of a juvenile Centrosaurus, a ceratopsian dinosaur, from the Late Cretaceous Dinosaur Provincial Park Formation in Alberta. This is the first documented evidence of carnivore interaction with a juvenile ceratopsid, offering insights into predator-prey dynamics or scavenging behavior during the Late Cretaceous period. The study suggests that small-bodied theropods, such as dromaeosaurs or juvenile tyrannosaurs, are likely tracemakers, though definitive identification remains challenging due to limited fossil evidence of such interactions.
