Did they talk?

Nobody knows if dinosaurs made sounds,

but we suspect they did. Parasaurolophus,

a hadrosaur, may have done this

by blowing air through its crest.

Other hadrosaurs had different-shaped crests,

suggesting they made different sounds.

Parasaurolophus

Talk like a frog

Brachylophosaurus had a short, solid crest.

It may have had an inflatable pouch on

the outside of this that could be used to

make noises, a bit like a frog’s

throat pouch.
