That classic scene wouldn't have been possible without animal sex noises.

And you didn't even know it. Now this beautiful scene all of a sudden looks weirdly sexual, doesn't it?

Since nobody knows how dinosaurs actually sounded, sound designer Gary Rydstrom created the infamous dino noises by recording animals, according to a 2013 interview in Vulture.

The squeal of the Gallimimus stampede was actually the sound of horny female horses. Seriously.

"A lot of animals in heat make a very unique sound," Rydstrom told Vulture.

What about that scary-as-fuck Velociraptor bark the animals make when they communicate with each other?

It's just a few harmless tortoises having sex. That's all. "Tortoises mating can take a long time. You've got to have plenty of time to sit around and watch and record them," Rydstrom told Vulture.

But that's not the only animal they used. "When the raptor shows up in the door window in the kitchen, the breathing noise is a horse," Rydstrom added.

And what about the horrifying sound the Velociraptors make when they eat the "clever girl" game warden?

It's just an angry goose. Geese hiss when they're mad, which is what you're hearing in the attack scene. "It doesn't take much to get a goose mad because they seem to get mad at everything. All you have to do is get close to one and stick a mic near its beak," said Rydstrom.

And what about the T. rex noises?

It's just a cute, little Jack Russell terrier. The howling, deafening roar however, was created by slowing down the sounds baby elephants make. Awww.

The singing Brachiosaurus?

It's just a slowed-down donkey. "There's this pitch shift in donkey vocals, and if you slow them way down, you get almost a hooting, songlike quality," Rydstrom said.
