The picture below is a parasaurolophus fossilised skull. He could make a noise with his big horn, it sounded a bit like the fog horn of a big ship. If you go to the Dinosaurierpark in Germany, you could hear what it sounded like, or you can have a look here: http://www.youtube.com/watch?v=lBU6zfI1b0U . It's a film to show how the horn worked, although it's really called a crest. But I didn't make that film.
