Those 'Jurassic Park' Dinosaur Roars Were Pretty Kinky

If you're planning to see "Jurassic Park 3D" any time soon, your experience might just be a touch tainted by this latest bit of disturbing information. Fair warning.

You know all those dino noises — sometimes endearing, more often terrifying — in the 1993 original version? Yeah, so it turns out several of those were just sexy time recordings of various animals.

Oscar-winning sound mixer Gary Rydstrom unleashed the icky details on how he gave Steven Spielberg's long-extinct beings some auditory life without any evidence of what they really sounded like to Vulture, and hell if he wasn't all up in the animal planet's beeswax to get 'er done.

Take, for instance, the velociraptors. Those suckers were terrifying as they barked at one another to communicate as a pack, right?

Wrong. That was tortoise sex. We did the research, and that, ya'll, is a 10-4.

Rydstrom explained, "When the raptors bark at each other to communicate, it's a tortoise having sex. It's a mating tortoise! I recorded that at Marine World … the people there said, 'Would you like to record these two tortoises that are mating?' It sounded like a joke, because tortoises mating can take a long time." And when the raptor gets real pissed and lets out that deafening screech noise, a lot of that menacing noise comes from a male dolphin in heat. "You can see a pattern here!" Rydstrom laughed.

And hold onto your butts, folks, because that's not all. Similarly naughty noises came into play with others, too, like the flocking gallimimuses. All that whinnying was drawn from some in-heat horses. If you listen closely, you can totally hear it.

"I remember recording a female horse, and the male horse came right by her and she squealed because she was in heat ... and she squealed at this male because he got a little too close and she was excited about the male, I assume. And that's the squeal the Gallimimuses make when they're passing by, and the squeal one makes when it's getting eaten by a T. rex."

Told ya this would affect the cinematic experience.

It wasn't all bump-n-grind with the "Jurassic Park" noises, though, thank goodness: The dangerous coo of the dilophosaurus came from swan songs, and the baby raptors hatching were, in fact, a buncha animal baby noises. So, those were innocent enough at least.
