Turns out the 'Jurassic Park' dinosaur noises were created using surprising and even scandalous techniques.

Everyone remembers where they were when they first experienced the horrifying noises these realistic recreations made. They also remember the inevitable nightmares they caused.

As it happens, these noises were created by real and living animals.

What's traumatizing is that several of the noises that were captured were animals having sex.

Jurassic Park's sound designer, Gary Rydstrom, spent months recording and editing these noises. He stated, "If people knew where the sounds in Jurassic Park came from, it'd be rated R!"

Take a look below at how the noises that terrified you were created.


Those freaky barking noises that these primal and terrifying dinosaurs made are actually just the sound of tortoises having sex. Yep.

Not so scary or more scary? We can't decide.

Rydstrom admitted, "It's somewhat embarrassing."


Gallimimus Stampede

These flocking dinosaurs made high-pitched squawks in Jurassic Park. Can you guess how those were created?

Well, Rydstrom said that when a male horse gets a little too close to a female horse and she gets excited, she squeals. Scared now?


Graceful Brachiosaurus

Recall that the first glimpse we get of the dinosaurs at Jurassic Park is the elegant and graceful brachiosaurus, which serenades the park visitors with long, trumpeting howls.

What other modern-day creature is so elegant and graceful? A donkey. Wait, what...?

"You think of donkeys, and they kind of yodel, you know? There's this pitch shift in donkey vocals, and if you slow them way down, you get almost a hooting, songlike quality," Rydstrom stated.

Slowing down small-animal noises is how Rydstrom achieved many of his bigger-sounding animal roars.


King of the Dinosaurs: Tyrannosaurus Rex

The T-Rex was the indisputable star of Jurassic Park, and its roar is something that no child can forget.

Yet Rydstrom's own pet dog, a Jack Russell terrier named Buster, supplied many of its sounds. A baby elephant is responsible for the T-Rex's terrifying roar. That's right, tremble and be scared!


One Sick Triceratops

The triceratops noises were created by dozens of cows on George Lucas' film site, Skywalker Ranch, where Rydstrom works, which is kind of perfect. A cardboard tube with a spring in it supplied the dying triceratops noises.

"When Sam Neill puts his ear right up to the chest cavity of the triceratops and listens to its breathing, there's a lot of cow in there, but the key element of the breathing is mostly me breathing into a tube," Rydstrom stated.


It's truly amazing how sound editors can make everyday noises sound so terrifying and convincing.
