Yes, it's a mistake. It should read pterosaur. It's now been almost 2 years of continuous grief over this in my inbox.

Actually the t-rex's noise is more terrifying than a roar, just imagine hearing it while walking in a forest.)

"All right so t rex is first" "When are they gonna play the sound" "Wait, that was it?"

It’s so scary, the sound of the t-Rex is theorised to be so low, that it would low-key rumble your chest, like thunder when you’re close to it. You would not see or hear a t-Rex when you are being hunted by it, you would feel it.

I absolutely LOVE the velociraptor sounds. Extremely reminiscent of a type of warbler, very bird-like and probably quite accurate.

Carnivore dinosaurs: mmmmmm Herbivore dinosaurs: *ungodly screaming*

Therapist: "The T-rex is extinct. It won't hurt you." The T-rex: *HHMMMMMMMMMMMMMM*

Not so fun fact: the low bellowing sounds of the T-Rex would be so low pitched that you would never even hear it. The noise would simply rumble through your entire body. Strange to think that you would feel noise. This also leads me to believe that T-Rex would’ve been an excellent ambush predator despite its rather large stature.

Imagine getting into a time machine only to hear those sounds.

Everybody gangster until the t-Rex goes mmmmmmmmmmmmmmmmmmmmmmmmmmmmm

Honestly, I’m a lot more scared of a damn near inaudible t-rex than one that roars.

If someone where to go back in time, I’m sure getting lost in a jungle hearing all these off putting sounds would’ve drive them insane

The jurassic park t rex sounded scary, but can you imagine being alone in a forest and you just hear the rumbling of a t rex?

The T-rex is literally making his own horror movie ambiance

When I was listening to the T. rex I was like “is the video gon start or-“ then I realized that was the noise lmaoo

Listening to this makes me sad, as creepy as some may sound. To know these creatures once roamed the Earth, only to be wiped out by something from space. Totally out of their control. Their last few minutes alive must've been so stressful and scary. Dinosaurs fascinate me ♡

props to the cameraman for time traveling for this one 💀

Other dinosaurs: roar, grunt Parasaurolophus, an intellectual: *orchestra tuning noises*

Just IMAGINE being in a forest and start to hear that "HMMMMMMMM" This is so much more terrifying that a roar

Perfect! That's exactly what they sound like in real life, back when they were all alive.

That white feathered T-Rex looks absolutely Adorable!

I hope they asked for the dinosaur’s permission to use their voices in this video

For those confused by T-Rex: Recently studies have suggested that the T-Rex couldn't roar, but instead bellowed, like a crocodile or alligator. Hence the ominous sound you heard.

the brachiosaurus sound sounded the scariest to me. imagine being in the jungle and seeing a long neck followed by a low, high-pitched roar? the t-rex was quite unexpected.

Oh man....love it. I would love to see a video, presentation, or paper detailing how they developed these sounds (i.e., the scientific modeling/thought process that went into determining what they would be).

What we expected from the T-Rex: **Epic roaring** What we got: **Earthquake vibes**

T-rex : microwave Velociraptor : blowing on the Rim of a bottle Triceratops : what we expect dinosaurs to sound like Brachiosaurus : ....some guy humming loudly at the end of a tunnel? Pterodactly : needs some wd-40 Parasaurolophus : area 51

I’ve never found a KZfaq channel that so accurately reflects my personal brand of weird. I’m absolutely in love with the content I’ve seen so far, the subjects range between many of my immediate and deepest interests. To think, I found this channel while listening to Dino-calls on the toilet. Would that it were a more elegant story than that, but that’s precisely what I mean by MY brand of weird. Absolutely brilliant.

Props to who time traveled and recorded the noises

Meteorite: I'm coming boys T-rex: Hmmmmmmmmm

The triceratops sounds like someone is pushing a heavy chair across a room

It would actually sound nice with all that birds and ambient. Beautiful.

The velociraptor‘s sound is literally the sound of a bittern😂

Everyones saying the T-Rex is nearly inaudible, I can't help but think that you'd *feel* the t-rex's roar more than hear it. Well, that and terror.

Birds: **chirp** **chirp** Horses: **neigh** Cats: **meow** T-Rex: *＊ＢＡＳＳ＊*

trex sounds like the endless deep abyss then trike sounds like it’s shitting itself

I’m pretty sure that if humans were actually sent back to dinosaur times, instead of being eaten, the dinosaurs, being unfamiliar with humans, would either fight the humans or run away like modern day animals in the wild.

Bruh imagine being an old prehistoric rat or something and you feel the ground rumbling bass of a T-Rex.

Other Dinosaurs: *Make some sort of grunting or moaning sound* T. Rex: ゴゴゴゴゴゴゴゴゴゴゴゴ

Absolutely incredible render. Thank you for sharing this with us.

The birds looking dinosaurs are so impressive.

i think the trex had a “roar” to the point where you could feel it throughout your body because it was that low, but you couldn’t hear it.

Fun fact: exposure to deep (often below human hearing) vibrations are a source of anxiety for humans. We are evolutionally geared to avoid places that have these deep humming noises for long periods of time. This is in part because unstable cave systems will often vibrate on these levels. Now we know another reason why.

Whether dinosaurs sounds were like this or not we'd all love to see and experience one even if it's horrifying.

A lot of respect to the cave man that invented a time machine got a camera went back to their home and recorded these sounds then came to the future where yt is invented just to upload this. Wow

Tyrannosaurus: *noises* Demon in my room: why would you say that omfg im crying

"Pterodactyl" *shows a picture of a quetzalcoatlus*

The T. rex roar is actually smart cus the prey would be looking around not knowing where it is while their hear rumbles, it’s right there stalking you.

Props to the guy who learned the hard way that a T rex bellow could burst your ear drums

These are honestly scarier than any roar, especially if they were mostly inaudible

Imagine running through a forest hearing those veloceraptor sounds in the distance, and then, when you think you are safe, deep in the forest, you feel the deep humming sound of a T-Rex.

Props to the sound guy for recording these. National Geographic should hire him 🫡🫡🫡

Velociraptors are terrifying the sound look attitude everything.

So amazing they didn't get eaten alive while recording those.

T. rex sound like a damn microwave

all this about a t.rex being able to burst your eardrums and shake your ribs just with its sound is making me want a jurrasic park type film with all the new discoveries of dinosaurs

Everybody gansta until the inaudible T-Rex comes out.

That moment when herbivore ones sound more terrifying than the giant predators

i love the concept of the t rex having a low humming sound instead of a roar. its so much more intimidating.

0:20 strangely it sound a bit more menacing than the xenomorph--like screams we imagine, since one don't expect something that sounds like it to be harmful...

Imagine you’re just an innocent creature in the forest and hear a deep microwave behind you

If I understand, T-rex grunt is a sound ambient.

Respect to the guy who went back in time to get this audio

Imagine hearing a damn t-Rex humbling in the jungle! You like: RUN

Imagine how fresh the air there must have been.

Veloceraptor: NHHHH HMMMH Jurassic Park Raptors: **noises from the depths of hell**

Wow I haven’t heard these sounds since 60 million years ago

The growling noise the Pterodactyl makes sounds UNCANNILY like my stomach when its upset.

Other dinos: Strange but relatively expected Rex: *The haunting vacuum of a cold unending void*

Velociraptor: bird sounds Triceratops: *herbivore screams* Para: *highish pitched screaming* Pterasaur: *Squawk* Brachi: *deep long N e c c sounds* T Rex: *Mmmmmmmmmmmmmmmmmmmmmmm*

Its so fascinating that these create actually existed on earth at one point, sad we will never get to really see them

That T. Rex takes "just vibing" to a whole new level

Other Dinosaurs: Animal like noises. T.Rex: *Intimidating and existence crisis inducing hum of death.*

Every other dinosaur: either screeching, vibrating or doing cow sounds Parasaurolophus: "ya like jazz?"🎶🎺🎶🎷🎶📯🎶

From this video, the T Rex sound may not seem that scary. But that sound not only is heard, but it's also felt, since it creates patterns that vibrate in the air. Also, said patterns can be loud enough to blow up your eardrums.

This is scarier. You’d be walking around while an indie horror game sounds are going off around you.

deep respect for the guy who went to record these sounds

T-Rex, Raptor, Brachiosaurus: "Y'all like fun whale sounds?" Triceratops: "I CAME TO BRING THE PAIN!!!"

1:59 me in the middle of the night camping with friends and playing this on my phone:

You’re telling me that massive ass T-Rex makes such a low frequency sound you can barely hear it? Even scarier than I previously imagined

The triceratops actually sounds like what we would think

Honestly, modern scientific recreations of these guys make them sound a hell of a lot cooler. A little more alien, a little less dramatic, but a lot more scary and more grounded in their modern descendents realm of sound

Brachiosaurus: *sounds like brachiosaurus* Triceratops: *sounds like a dame spinosaurus*

Imagine a big flock of those Pterosaurs flying right overhead, all making that noise nonstop and interrupting each other with their calls. I would think my ears would be ringing for a day if it happened.

"Back in my day, the music sounded so much better." The music:

The t rex is lowkey the most terrifying sound you could hear in nature

Imagine camping with your homies and all of a sudden you hear any of these noises

That Triceratops is the SCARIEST and is far more frightening than a Gigantosaurus. I couldn't even hear the damn T-Rex. Just NO way..

Fun fact: that low roar a Tyrannosaurus Rex has is loud enough to burst your eardrums. Honestly, which would be scarier…a roar like in the movies, or a low, humming that shakes the ground.

T-Rex in Jurassic park: AAAAAAaAAAAA T-REX in real life: mmhhhmmmm

Lol this is so nostalgic, I cant believe its been 65 million years. It feels like yesterday

I'd like to imagine that they just grabbed a dinosaur's neck bones, reconstructed the vocal chords out of fake flesh and shrink, took a tube, and just screamed to see what it would sound like

What people in 1999 thought dinosaurs sounded like ROARRRREEEEE 2020: HMMMM

Impressed with the quality of such an old recording. Edit: I am super impressed some people think I am serious.

I get the t Rex sounds are loud enough to burst your eardrums, but imagine if it was much quieter. Just a low, menacing growl. That's would be much more terrifying than an ear-piercing roar or a ear drum destroying growl

0:20 honestly hearing that in the wild nearby might be scarier than any of the Jurassic Park dinosaur sounds.

Everybody gangsta till the air starts vibrating.

T-Tex: *Spooky forest microwave* Velociraptor: *Coolest bird* Triceratops: *Angry hippo* Brachiosaurus: *Drunk Cow* Quetzalcoatlas: *REEEEEE* Parasaurolophus: *Distorted Halo theme*

Imagine being trapped and you hear the dreaded low Trex hum, footsteps getting louder and all you can do is pray and piss your pants knowing your going to be on the wrong end of its gigantic jaws of death.

The nostalgia hit me like a freaking truck 😢
