Eudromaeosaurs are presumed to have all been hypercarnivores. However, their considerable variation in size and distribution throughout the Cretaceous implies that there was likely a great variety in the composition of their prey.
Possible modes of eudromaeosaur predation
Hunting much smaller animals
Restraining and disemboweling similarly-sized animals
Individual combat with larger or similarly-sized animals
