IF: Duet

A bit of a last minute entry this week. I had a few ideas but not much time then came up with this.

A pair of Parasaurolophus. This was a large Hadrosaurid dinosaur from the late cretaceous of New Mexico and north America.

For a long time it was believed that this dinosaur lived an amphibious lifestyle perhaps using its crest as a type of snorkel! This is now known to be completely wrong and Parasaurolophus was a land animal living in herds.

Three different species are recognised each with differences in their head crests though it is also possible that this indicated differences in the sex of the animal.

It is now thought that the crests were used for display and in the production of sounds for warnings, mating and general communication.

I wonder what they'd have sounded like?
