Diet and feeding

Two eudromaeosaur teeth: Zapsalis (left) and Velociraptor (right)
  • Morphological disparity in teeth[2]
  • Gnawing behavior[3]
  • Juvenile ceratopsian bite marks[4]
  • Yurgovuchia found with ankylosaur and iguanodont remains[5]
  • Azhdarchid scavenging[6]
  • Cedar mountain niche partitioning[7]
  • Fighting dinosaurs[8]
  • Actual feeding process[9]
  • Diet vs unenlagiines[10]
  • Digging predation[11]
  • Ontogenetic dietary shift in Deinonychus[12]

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
  •  
    Forming groups to hunt larger animals

Roles in ecosystems

edit
  • Ecology of mesopredators in Aguja[13]
  • Prince Creek teeth and ecology[14]

Locomotion

  • Walking cycle reconstruction[15]
  • Comparative dromaeosaurid locomotion[16]
  • WAIR[17][18]
