Common Name: Corythosaurus
Species: Corythosaurus Casuarius
Time: Late Cretaceous
Wild: If ever there was a loud dinosaur that could be heard across a distance, it is the Corythosaurus. They are known for their singing and different calls which can be handy for directing other members of their herd to do something or to warn of a nearby predator.
When flocking, they have intense vocal patterns to direct other dinosaurs, which in a herd can cause a stampeding effect. They can also mimic sounds of dinosaurs like carnivores to deter smaller ones from attacking or staying away. Unfortunately, this is a double-edged sword as it can also attract bigger or rival carnivores.
Domesticated: A tamed Cory can be invaluable. One of these can scare away wild dinosaurs away from a location, depending on their mimicked vocal patterns. Well placed Cory's can be employed for several different tactics ranging from taming, hunting, or redirection. They can rally nearby allied dinosaurs to their location to defend an area or pave a way for escape. I've heard "choirs" of Cory's sing amazing melodies in villages often just as entertainment.
