What kind of noises did dinosaurs make?
<|assistant|>
Dinosaurs may have vocalized with a range of different noises depending on the species. These may have included roars, hisses, growls, clicks, grunts, and even whistles. Some species of dinosaurs may have even communicated in clicks and whistles similar to those heard in certain bird or reptile calls today. Recent research on Tyrannosaurus Rex fossils suggests the species may have communicated in a low "growling" noise to show aggression.
