What Sounds Were Used to Create Dinosaur Roars?
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.
A mixture of sounds were mashed together in order to procure menacing sounds. Which animals did creators use, by chance? 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.

How Suspense is Built
In the first movie, there were times where you’d slowly feel the hairs rise on the back of your neck. The filmmakers associated with this project didn’t hit you over the head with constant dinosaur chases or scenes in which they’d terrorize people. On the contrary — they were quite careful when unleashing them on screen. Jurassic Park is 127 minutes long (just past the two-hour mark). During that time, dinosaurs appeared on screen for only 15 minutes. The rest of the time, their ‘presence’ was left to the viewer’s imagination through off-screen roars, footprints, and the carnage left behind.
