"Jurassic World" is coming out later this year and while many are undoubtedly excited to see dinosaurs again, there are some who might either be amused or traumatized to find out that creating their characteristic sounds required a bit of help from maiting tortoises, CNET reported

While numerous studies have been done on dinosaurs, they are actually still a mystery to us and most of what we know are based from scientific studies and occasionally, artists, who reimagined the extinct creatures. However, there are some details about them that are out of reach, such as what they sounded like.

Gary Rydstrom, the sound designer for Lucasfilm, was tasked to create dinosaur sounds from scratch for 1994's "Jurassic Park," which he did by recording animal noises. He shared the details during an interview with Vulture back in April 2013, and pointed out in particular that to create the distinct velociraptor sounds in the films, they took to recording tortoises that were mating.

"It's somewhat embarrassing, but when the raptors bark at each other to communication, it's a tortoise having sex," he shared. He even stated that he recorded that at Marine World and revealed that tortoises actually took a long time to mate.

Rydstrom ended up winning two Academy Awards for sound design and mixing for "Jurassic Park." It's not quite a bad deal for getting to hear and witness tortoises being intimate.

While not attached to the upcoming Jurassic film, many still remember the tale, such as SF Gate's Peter Hartlaub who recently interviewed Rydstrom.

"The bark that the velociraptor makes when it comes in the kitchen and it barks 'Arp! Arp!' That's the sound of a tortoise that is mating," Rystrom said, adding that it was "a little sexual" to see the males climb the females' shells and mate.

One can only wonder what the current sound designers for "Jurassic World" did to get sounds for the new dinosaurs, and also as the raptors were featured quite a bit in the official trailer.

They are also seen in the recently leaked Super Bowl XLIX trailer that appeared online, according to Christian Today.

YouTube took it down due to copyright claims, but some were still able to view it and the description of the trailer is making its way online. The trailer allegedly showed the gyropshere, a popular ride in the park that helped guests get close to the dinosaurs, while another scene showed leading man Chris Pratt taming the velociraptors before telling Bryce Dallas Howard, "It's like taking a stroll through the woods."

Does Pratt know he's petting a creature that makes sounds similar to mating tortoises?

"Jurassic World" will be released in theaters on May 11, 2015.
