  • Small plant-eaters probably heard higher frequencies, which was useful for pinpointing the location of a predator and warning calls from other dinosaurs.
  • Large plant-eaters probably heard lower frequencies, which was useful for communicating over long distances
  • External ears would have been similar in appearance to those of living birds and reptiles.
  • The structure and large size of some theropods' middle ear cavities suggests that they may have heard low frequency sounds, which would have been useful for detecting far-off prey.
