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.
