Dino Roar
The sound audio above is the sound of a dinosaur's roar. It is how the dinos sound back long ago before the dinos died. It may sound like something else like it relatives or a lion's, but it not. It sound like the way it is because since they don't know the actual sound of it's roar, movies like Jurassic Park use vocalization from other animals too, like it ancestors the birds and crocodiles. Some paleontologists believed dinosaurs couldn't roar due to lack of evidence, but instead thought they made closed-moth sounds like boons, rumbles, and growls, though some scientists do believe that dinos could have possibly have roars back then, though without proper research, it is possibly unlikely for them to.
The dinosaurs make the sounds of growls and roars for various purposes in their species. The main reason they roar is a warning to others, especialy predators, that they are coming. It's a sign that they are around and that it's enemies and prey should run as they are in fear of an attack or threat. They also use those sounds to communicate to each other, like warring there groups of danger or telling them of a hunting activity. Some use their roars and growl sounds to attract mates and bond with each other. These roars are used as signals for body language to tell them about something important. The roars and growls are also used by leaders to command their packs to make them do as they say and show leadership and respect form the group. Their roar is very loud and sounds very fearsome to hear.
