What did dinosaurs sound like?

1. 1

   Tiny says

   Sounds don't turn to stone, so no fossil can tell us for sure. But remember, birds are dinosaurs, and some birds call with their beaks shut. A dove puffs up its neck and goes coo. Scientists think some dinosaurs may have cooed or boomed like that, with their mouths closed!

   Why would a big dinosaur keep its mouth shut to call?

   To call with a closed mouth, an animal pushes air into a stretchy pouch in its neck. The sound comes out deep and low. Only bigger animals do it, about dove-sized and up. Lots of dinosaurs were much bigger than a dove, so many of them could have made deep, rumbly booms.

3. 3

   Could any dinosaur make a really loud call?

   Parasaurolophus had a long crest on its head with a hollow tube inside. The tube ran up through the crest, looped round and came back to the skull. Blowing air through it might have made a deep, trumpeting bellow. Nobody knows for sure, but it's a good guess.
