An ongoing study utilizing the most recent scientific data on dinosaur vocalizations. Sounds are produced by myself and digitally workshopped from modern non-syrinx based avian reptiles. Using skull and olfactory cavity proportions, one can attempt to recreate the flow of sound, frequency, and volume of each animal. Much study is required for each particular species, and often several phases are trashed due to general unlikelyhood. The final results are based on acute representations of what sounds would be most comfortable and base-line for each animal. Video also includes 2 marine reptiles and a pterosaur, even though both are much more difficult to produce accurately.

Aim: To be more sophisticated than Julia Clarke's rendition, which included: combining the booming call of the Eurasian bittern with the growling vocalizations of the Chinese crocodile, and then scaling it up to T-rex’s estimated size (about 12 meters or 40 feet long), what they got was a ominous low rumble.

If you listen really closely, you can also hear me shitting myself in the background.

I'm from Mesozoic era and I can confirm that this is 100% accurate. Its been 65 million yrs since I last say them. Its so Nostalgic to hear their voice again.

[-NGC--]

I was NOT expecting velociraptor to make the exact same sounds as Jerma985
fascinating

[porcus]

I cant even fathom how loud a t Rex must have been.

[StuffyMc]

I want so bad to just see them with my own eyes. Dinosaurs almost feel like fiction because there's so little left of them, but it's infuriating to know that they were real and walked the earth just like animals today, but the gap of time is utterly untraversable.

[longerthanyouthink]

Every other dinosaur: Creepy, otherworldly sounds
Dryptosaurus: Sounds like my grandfather stepped on a Lego brick

[gigintoki]

I was laughing at That dryptosaurus sound until...at 2:28 he started that satanic laughter like he knows something we don't know or as if we have fallen into some of his trap

[hope-ukuh]

It’s nice to hear their voice again after millions of years I miss my pets

Fun Science Fact: human bodies are sensitive to what is called "infrasound", sounds so low that very few things currently around make them. Feeling these sounds (we can't hear them through our ears, we instead feel them with more sensitive organs, including our eyes) causes intense fear and anxiety, as well as creating hallucinations on the edge of your vision. It is believed these traits were beneficial by helping our ancestors avoid things like unstable cave formations and dangerously powerful storms, which are two of the naturally occurring versions of infrasound. Another naturally occurring source of infrasound is very large animals, including predators.

This is entirely unrelated to the deeply terrifying sounds these animals potentially made, but imagining yourself increasingly anxious and seeing things on the edge of your vision while being stalked by a T-Rex sounding like the above might help you get a better picture of what experiencing this would be like.

Velociraptor- angry seal
Utahraptor- cross between a pig and crocodile
Dryptosaurus- man raised by gorillas
Tyrannosaurus- prehistoric air raid siren
Triceratops- evil rhinoceros
Elasmosaurus- two whales made of rubber fighting
Mosasaurus- the last sound you hear as the alien blaster disintegrates your brain
Quetzalcoatlus- COD zombie charging up a space laser
Spinosaurus- world’s most terrifying wolf

[jacobnardone]

When I heard the Tyrannosaurus calls, I felt some kind of primal instinct to run.

I want to see a survival horror game called *100M* in which you spawn into the mesozoic as a naked human. No commentary, no music, no backstory, just one objective: SURVIVE.

[saltycracker]

This version of the T-Rex sound is actually 100 times more terrifying than the ones I've heard in movies, that almost always sound like a loud horn. This is something more down to earth and at the same time sounds totally alien.

[smilodnfatalis]

You didn't have to add echo to make it extra creepy, but you did that. You did that for us.

[Godzillaisles]

everyone saying the trex sounds scary but the Spinosaurus should NOT sound like that. I'm not saying its not accurate, but it sent a shiver down my spine.

[dancyr]

I can envision that Spinosaurus head shaking wildly as it utters those spine chilling sounds

[Kyle_Schaff]

Here’s a dino sound fact for you guys.

Scans of a T. rex skull have revealed that their olfactory would have been adept at hearing low frequency sounds—even lower than we are capable of hearing. This means _those_ were the types of sounds they would hear in their environment. Imagine instead of being able to hear a T. rex approaching, you would *feel* the vibrations of its vocals getting closer

EDIT: Definitely not the olfactory, but I’ve forgotten the name of the relevant part of the brain

[Rafael_Peixoto]

Dude that Utahraptor "laugh" sent CHILS DOWN MY SPINE

[cloudforest]

So beautiful we know they had feathers. Trying to replicate extinct sounds is amazing!

[lobotomized-daydreamer]

Honestly this video brings back my childhood fascination with dinosaurs, such a cool nostalgic feeling I can't put into words, thank you. It's like being in the museum for the first time again
