What did dinosaurs sound like?

We tend to associate dinosaurs with ground-shaking roars, but the latest research shows that this is probably mistaken.

You'd feel it more than hear it – a deep, visceral throb, emerging from somewhere beyond the thick foliage. Like the rumble of a foghorn, it would thrum in your ribcage and bristle the hairs on your neck. In the dense forests of the Cretaceous period, it would have been terrifying.

We have few clues for what noises dinosaurs might have made while they ruled the Earth before being killed off 66 million years ago. The remarkable stony remains uncovered by palaeontologists offer evidence of the physical prowess of these creatures, but not a great deal about how they interacted and communicated. Sound doesn't fossilise, of course.

From what we know about animal behaviour, however, dinosaurs were almost certainly not silent.

Now with the help of new, rare fossils and advanced analysis techniques, scientists are starting to piece together some of the clues about how dinosaurs might have sounded.

One might as well ask what mammals sound like. Huge differences. Probably true of dinosaurs, too. I doubt if ovoraptor sounded anything like hadrosaurs.
