Truthfully, we have no idea what dinosaurs actually sounded like. We can only assume or guess as to what their aggressive roars would resemble. Seeing as if there’s no audio of a dinosaur present, those working on Jurassic Park had to get really creative.

Well, many of the sounds given to these dinosaurs came from walruses, hawks, dolphins, rattlesnakes, penguins, tigers, elephants, dogs, swans and alligators. The T-Rex in particular was a combination of all of these animals.
