While you might imagine dinosaurs screeching or roaring like they did in the Jurassic Park movies, scientists haven’t been able to figure out the noises they actually made. New research is bringing us closer to understanding how they might have sounded. The new theory is that dinosaurs may have actually sounded similar to the throaty growl of crocodiles or the loud honking of geese.
Birds and crocodile-like reptiles are the closest living descendants we have to dinosaurs. A recent paper published in the journal Historical Biology pointed out that crocodiles and mammals make sound through a vocal organ called a larynx, while birds use a syrinx. Present day predators, like lions and bears, roar when they attack, so we assume all predators did. However, the new theory claims we should model our view of dinosaur sounds on creatures that use sound to call mates and defend territory.
In 2013, the oldest fossil of a voice box was discovered. From there, a team of archeologists figured out what sound its anatomy could make. Apparently, it most closely related to a syrinx which dinosaurs most likely sounded like a modern day goose or duck.
