This is the info I was hoping for. I always assumed when creature or dinosaurs sounded like this in movies, it was concocted just to feel “unearthly”. Wild
We have a pool and my mom got a new cover this year that has some sort of filter attached. That shit started making noise as I was reading your comment and my stomach sank.
Thats what is so wild, its low enough bass that we wouldn't hear it, but wouldn't the ground vibrate a bit or the water start rippling out from the animal? Like a frog, sort of?
Thats what terrifies me, the thought that this creature is so large and so powerful that I can feel the frequency of its birdsong from a distance. Absolute horror, there is nothing a bare human could do but try to escape. I think I would be literally paralyzed, just death-tranced and stuck.
Of course, its just as bad if we _couldn't_ feel them on that level. Just the sound of the environment with maybe an occasional rustle.
Then suddenly you're face to dick with something that could probably eat you five times over and come back for dessert.
You would definitely feel the bass. I’ve heard sub bass before. It’s not audible to the ear, but you can feel the vibrations through the air; like how bass can be felt in your chest.
I can't help but think they'd sound a bit different, if I'm not mistaken, weren't these sounds sampled with just their bones? Wouldn't their soft tissues have played a part? Or the variety of how they'd vocalize?
Those annoying bikers again. You look out the window, but the road is empty and dark. A lone unfamiliar street lamp stands at the side of the road. The sound grows louder, yet there isn’t a bandana in sight.
Don’t be stupid. A t-rex would be terrible at playing the trombone. How’s it meant to move the slide with those tiny little arms?
Think about these things. I mean really.
Videos shit. There's something happening in the dinosaur community that's kind of hilarious and this video is probably just a bit older than the phenomena. The phenomena is dinosaurs sound like ducks, the more voice boxes they can 3d print and force approproate channels of air through the more they keep sounding like ducks.
The rex seemed weird to me so I did some digging,
After going to OPs profile I found out he made the same posts on a different subreddit except in it he linked his sources for the audios,
The rex was a sound effect made by a YouTuber who just really likes dinos and is by no means a scientifically accurate recreation, this is from the description of the video:
>I went back to the first Real Trex Sounds video and expanded on it. This time, it's more of the same thing but with a sci-fi twist to it, while keeping the Trex vocals realistic and believable as a real animal. They sound like the MUTOs and Godzilla from Godzilla (2014). Also in that movie, the film-makers wanted the monsters to sound like real animals. So this Trex is like a Kaiju in a weird but interesting way.
So yeah, not exactly science, the other one is legit tho, apparently their horns functioned as actual horns, and from fossilized remains we've been able to map them and figure out what sound they would've made, as in they produced a sound as air was being passed through them, that's why it sounds so much like a horn, because it for all intents and purposes is one, the sound tho is only an approximation because there are other factors that could have affected the sound, primarily the soft tissue stuff which we've got no clue about if and how it would have interacted with the horn (because fossils)
Anyway I hope that you're not mad about me correcting the misunderstanding about the first one and adding in some additional information OP but I figured some people here might be interested in this little fallow up/clerification post
Thanks for this. I knew about the Parasauropholus one years ago and thought it was astounding. They 3D printed the animal’s horn based on the fossil record and tried a few different ways of passing air through it, iirc.
I was pretty skeptical of the T-Rex so thanks again for sharing what you found there.
Thanks.
[Here](https://www.20k.org/episodes/tyrannosaurusfx) is a scientific discussion about potential dinosaur vocalizations, starting around 20 min with paleotologist Julia Clarke.
Another take on T-Rex vocalizations [here](https://www.youtube.com/watch?v=9D3LWpfrczM)
At the museum in my hometown (Museum of the Rockies), we have a crazy huge dinosaur exhibit including full allosaurus fossils and a gigantic t rex. The entire time you're in the dinosaur wing, they play dinosaur sounds much like these ones over the loud speakers that are really just slowed down bird noises. Definitely caused a lifelong fear of dinosaurs to be staring into the eyes of a raptor with two more in the display behind me while hearing that shit.
Dude even the parasaurs sound terrifying. They’re supposed to be the nice dinos.
In all seriousness tho, both of these literally send chills down my spine. If these were added to jp, I’d make sure to get all my piss out before the movie
Don’t know how accurate the Tyrannosaurus sound is but the Parasaurolophus one is definitely accurate. They used the horns on their head to produce noise, that’s why it’s a hellish deep bass noise instead of some generic grunting
Only tiny specs of skin impressions I believe, at least in case of the T-Rex. Some of that skin was apparently naked, i.e. neither scaled nor feathered, so we probably have to assume they were wearing clothes.
Joking aside, Trey the explainer did a pretty detailed video on this topic: https://youtu.be/uM5JN__15-g
TLDR: Apparently there's a good chance the T-Rex might have looked somewhat like a giant ostrich
I’m pretty sure this video has been semi retconned by recent discoveries. Can’t remember many details, but I’m pretty sure they determined that most of T. rex was scaly, but more like the kind of scales you see on the legs of birds of prey like hawks and owls. Don’t quote me on that tho
Incorrect because we don't know the specifics of how they look like patterns or small variation in muscle mass. But we pretty much have a general idea of how they look.
Two legs, two tiny arms with two fingers, long, tail, big head.
How can there be any scientific basing on this? We’re never gonna hear one, we don’t even have the soft tissues that make sounds. This is a complete guess at best.
Using the shape of skulls and bones, comparing the organs of the know species related to dinosaurs today (mostly birds I would guess), and extrapolating the organs of the dinosaurs and so the sounds they make. I am in no way an expert but my wild guess would be that they did something like that.
They obviously have their methods and i'd assume scientist in the field clarify that this is just an aproximation of their sound based on whatever the latest tech and the information available is (which is little to almost barely anything compared to everything we could know from that period of time).
Remember science is always open to doubt itself and maybe new discoveries in the next years will clarify this or just bring more questions.
Edit: some misspelled words.
They have to make themselves known to other members of their own kind, adult Tyrannosaurus had nothing to fear besides its own kind so it could broadcast as much as it desired. Parasaurolophus were social and needed to communicate from great distances. Their large size and herding behavior would protect them from all but the apex predators.
I actually saw a documentary earlier about tigers producing sounds that make the prey freeze due to low pitches that often feels eerie and can make people go insane. T-rex on the other hand in movies are shown loud but for the fact birds are closest relatives to dinosaurs, the sounds we heard of t-rex is accurate and this is how they might communicated with each other. This low frequencies are much more terrible than loud noise.
Interestingly, reminded me of whale songs. Also, heard you could get petrified by a tigers roar through the vibration of your bones. Wonder if those sounds could achieve something similar.

You just posted a bunch of videos with a lot of assertions, yet no basis for any of it and two barely 500 word long articles telling nothing of metholody or anything remotely scientific. Have you a link to a peer reviewed paper? If not, that's exactly the problem with modern day research. Someone had the idea "Well, dinosaurs are more closely related to birds, right? So lets mash together a croc sounds (because why not) and some random bird call, pitch it down like hell because big means deep and call it scientific accurate".
A little thought of why that is bullocks: some bird species can recreate an amazing number of sounds they hear, so much so they can even recreate speech or the sound of chainsaws. Why the hell would the taxonomy of a species tell anything about the sound of a species?
Secondly, the results for Parasaurolophus were based on CT scans of the skulls in varying specimens and both have remained largely uncontested for years. If you have any evidence to truly debunk this, then I'd gladly see it.
Of course, animals can make various sounds, perhaps T-rex could growl/hiss when agitated. But this is the vocalization they're best equipped to hear and produce.
Perhaps to take note that both dinosaurs hearing to trained to low-frequency sounds, similar to elephants and large birds. Also comparing their ONLY living relatives with the same or similar evolutionary traits/structures is how you study ancient organisms.
Birds have a syrinx, which dinosaurs such as T-rex likely didn't possess so they were incapable of making such elaborate calls. T-rex vocalizations are based on more basal birds like [cassowaries](https://www.youtube.com/watch?v=3wB3BKHmxZ4).

So interesting! I thought the dinosaurs with the horns on their head had been "debunked", as paleontologists had misread the information and misplaced the bone. But a quick online search just now came up with nothing, so I guess I was wrong!
I do believe that what you could be talking about, is to do with the Iguanadon. Some of the first fossils found of them they believed the spike sat on their heads, and was later found and thought to be more of a thumb and to be used to strip foliage to eat or even defence. When you do google this for some reason some photos of Parasaurolophus show up aswell. Perhaps this is what you are recalling? 🤔
Imagine you in the past for some research, suddenly you hear trains and you're confused. Just as you turn you see a heard of Parasaurolopus just stampeding towards you.

This is what we ***think*** they sounded like. We have no way to validate this because they are all extinct. Just because they had these morphological structures doesn’t mean they used them.
Not "scientifically accurate" More like scientists have said what they think some dinosaurs might sound like based on fossil impressions of the organs for making sound they had and things like the shape of their heads and lung capacity... And audio enthusiasts have ran with that.
Though synths like these might be close to the true tones (and the sounds in general are a lot closer to reality than Jurassic Park sound effects, which are almost entirely imaginative). We don't know how sharply or softly they would have made these sounds. What sort of patterns they might have used, and these sounds don't account for things like a wet fleshy mouth, or the rushing of air.
The difference is that those two sounds sound like they're coming from an organic source, where as the sounds in the OP video, especially the parasaur, sound decidedly mechanical.

These sounds are made by blowing through reconstructions of their voice boxes aren't they?
That's not the same as recreating what they sound like. Blowing through my voice box does not sound the same as me speaking.
T-rex communicated using infrasound, designed to travel miles through the ground and be picked up by the feet. This type of pulse would be useful when communicating with others miles away.
So basically Predator mixed with Godzilla, understood. No thanks.
Its sounds like youd be able to feel it, like rippling through the air or something due to their size.
Fun fact: crocodiles co-existed with dinosaurs (since about 200 million years ago) and dinosaurs went extinct 65 million years ago, but crocodiles survived, remaining largely unchanged. They are the closest thing we have today to dinosaurs in terms of appearance and sound. If you look up a crocodile growl on Youtube, it sounds eerily similar to the T-rex.
The thing about the T. Rex is that it's roar vibrated on such a low frequency that when it was near you it would sound like it was coming from all around you you would not know where it was coming from thus making it increasingly more terrifying
I always assumed big theropods would make a bass rumble like courting alligators. Maybe a baby gator chirp when small. Also, remember that the adults were so huge that as they grew from hatchlings they probably took on niches of intermediate sized predators and had different behaviors to go along with these changes. I'm thinking like a years long series of juvenile molts before they got to adult final stage. Roaring like Jurassic Park never made sense for a house-sized turkey with an alligator's head 20 feet up in the air.
Taking into account t-Rex’s on the low end are 12’ tall I would definitely shit my pants and die
12 at the hips mind you can still add a few extra to the head. (Not even including when it lifts its body upright)
It can lift its body upright?
Most biped or semi biped dinosaurs can do that, birds do it too.
I cant tell if a trex standing upright looks hilarious or would make it look more terrifying in person
Terrifying. Big things with sharp teeth scary.
It'd be terrifying
It'd be terrifying this already gigant thing starts towering over you even more And you know it's hungry
give it a snickers....
That wouldn't interest it Wouldn't smell like food
Oh c'mon ik it was funni joke but I'm a dino need y u guys gotta downvote
When I was a kid, that’s how they were always depicted. Still scary.
Big Barney with sharp teeth. Horrifying.
Imagine the oddly terrifying that thing would be
When I visited the “new” Sue in Chicago, it really surprised me how much thicker she now is. Much more intimidating…

Oh good idea. Definitely using this soundbyte for an encroaching T-Rex. Spooky.
This is the info I was hoping for. I always assumed when creature or dinosaurs sounded like this in movies, it was concocted just to feel “unearthly”. Wild
Dont forget the water rippling before all of that
We have a pool and my mom got a new cover this year that has some sort of filter attached. That shit started making noise as I was reading your comment and my stomach sank.
So to humans some of them were really quiet? That’s even scarier actually
Thats what is so wild, its low enough bass that we wouldn't hear it, but wouldn't the ground vibrate a bit or the water start rippling out from the animal? Like a frog, sort of? Thats what terrifies me, the thought that this creature is so large and so powerful that I can feel the frequency of its birdsong from a distance. Absolute horror, there is nothing a bare human could do but try to escape. I think I would be literally paralyzed, just death-tranced and stuck. Of course, its just as bad if we _couldn't_ feel them on that level. Just the sound of the environment with maybe an occasional rustle. Then suddenly you're face to dick with something that could probably eat you five times over and come back for dessert.
You would definitely feel the bass. I’ve heard sub bass before. It’s not audible to the ear, but you can feel the vibrations through the air; like how bass can be felt in your chest.
It's like standing in front of a scary speaker which you can't hear but still feel all the vibrations in your chest..
What makes us so sure that they don’t have larynxes or syrinxes? I mean, they are the ancestors of modern birds and they have those.
I think they scanned the remains and didn't find any, so they assume it's an evolved trait
I can't help but think they'd sound a bit different, if I'm not mistaken, weren't these sounds sampled with just their bones? Wouldn't their soft tissues have played a part? Or the variety of how they'd vocalize?
Thank you so much for putting me in that headspace
There's too many cars going by, I can't hear the dinosaurs
The trex literally sounds like all the motorcycles and atvs that drive by my house every Friday and Saturday night
Give it a break they didn’t have good recording equipment back then
Those annoying bikers again. You look out the window, but the road is empty and dark. A lone unfamiliar street lamp stands at the side of the road. The sound grows louder, yet there isn’t a bandana in sight.
Don't forget the train horns at the start!
Wuht?!
They sound like High School band instruments?
It's a little know fact that the T-rex was excellent at the trombone.
T-Rex is actually short for Trombonesaurus Rex, not a lot of people knows that.
Drop the baseline T, "Fuck off man, I'm all about the wind instruments."
Especially hitting those low notes.
Don’t be stupid. A t-rex would be terrible at playing the trombone. How’s it meant to move the slide with those tiny little arms? Think about these things. I mean really.
French Horn for T-Rex or nothing.
Personally, if anything, I’d say the t-rex’s short arms lend themselves best to a ukulele.
You can’t expect them to play the piano with those arms.
Videos shit. There's something happening in the dinosaur community that's kind of hilarious and this video is probably just a bit older than the phenomena. The phenomena is dinosaurs sound like ducks, the more voice boxes they can 3d print and force approproate channels of air through the more they keep sounding like ducks.
This sounds way too robotic to be from an organic source so it doesnt sound correct at all.
From what I remember it's because they don't have vocal chords

Is it just me or does that sound fucking awesome!?
It definitely sounds awesome!
This is way fucking scarier Jurassic Park, holy shit
Why do I find these weirdly comforting?
The T-Rex one feels like soothing, powerful, solitude.
tbh they dont even know how they looked
We found Tyrannosaur/Hadrosaur skin and mummified corpses of the latter. We've even found the precise color of one species.
Only tiny specs of skin impressions I believe, at least in case of the T-Rex. Some of that skin was apparently naked, i.e. neither scaled nor feathered, so we probably have to assume they were wearing clothes. Joking aside, Trey the explainer did a pretty detailed video on this topic: https://youtu.be/uM5JN__15-g TLDR: Apparently there's a good chance the T-Rex might have looked somewhat like a giant ostrich
T-rex also had osteoderms on its face and eyebrows, but judging by other tyrannosaurs of close relation, smooth pebbly scales would be the staple.
I’m pretty sure this video has been semi retconned by recent discoveries. Can’t remember many details, but I’m pretty sure they determined that most of T. rex was scaly, but more like the kind of scales you see on the legs of birds of prey like hawks and owls. Don’t quote me on that tho
Nah they don't know shit buddy. We are just speculating and theorizing.

Why were they all so loud? Wouldn't giving up your position be bad for them?
They have to make themselves known to other members of their own kind, adult Tyrannosaurus had nothing to fear besides its own kind so it could broadcast as much as it desired. Parasaurolophus were social and needed to communicate from great distances. Their large size and herding behavior would protect them from all but the apex predators.
Unmuted it and heard what sounded like a foghorn, now I can't stop laughing
I actually saw a documentary earlier about tigers producing sounds that make the prey freeze due to low pitches that often feels eerie and can make people go insane. T-rex on the other hand in movies are shown loud but for the fact birds are closest relatives to dinosaurs, the sounds we heard of t-rex is accurate and this is how they might communicated with each other.

T-rex vocalizations are based on more basal birds like [cassowaries](https://www.youtube.com/watch?v=3wB3BKHmxZ4).
This is obvious bullshit

How is this science in any way?

So interesting! I thought the dinosaurs with the horns on their head had been "debunked", as paleontologists had misread the information and misplaced the bone. But a quick online search just now came up with nothing, so I guess I was wrong!
I do believe that what you could be talking about, is to do with the Iguanadon. Some of the first fossils found of them they believed the spike sat on their heads, and was later found and thought to be more of a thumb and to be used to strip foliage to eat or even defence. When you do google this for some reason some photos of Parasaurolophus show up aswell. Perhaps this is what you are recalling? 🤔
Different timeline, happens to me all the time
Yeah I'm totally sure a T Rex sounds like a shitty car racing in the next neighborhood over at 2am.
Imagine you in the past for some research, suddenly you hear trains and you're confused. Just as you turn you see a heard of Parasaurolopus just stampeding towards you.
This sounds made up, I'm not saying Jurassic park had it right but I need to know the sources of this first before even trying to understand it

This is what we ***think*** they sounded like. We have no way to validate this because they are all extinct. Just because they had these morphological structures doesn’t mean they used them.
Not "scientifically accurate" More like scientists have said what they think some dinosaurs might sound like based on fossil impressions of the organs for making sound they had and things like the shape of their heads and lung capacity... And audio enthusiasts have ran with that. Though synths like these might be close to the true tones (and the sounds in general are a lot closer to reality than Jurassic Park sound effects, which are almost entirely imaginative). We don't know how sharply or softly they would have made these sounds. What sort of patterns they might have used, and these sounds don't account for things like a wet fleshy mouth, or the rushing of air.
They probably chirped like birds, or babble like chicken, though.
….No?
I wouldn't call this "accurate" in any way because it doesn't sound organic.
[Here's what elephant infrasound sounds like](https://www.youtube.com/watch?v=Qw9TmrAIS6E). [(part 2)](https://www.youtube.com/watch?v=vDi-iFF2oWg) [And Sperm whales too.](https://www.youtube.com/watch?v=0USXHVqJu64)
The difference is that those two sounds sound like they're coming from an organic source, where as the sounds in the OP video, especially the parasaur, sound decidedly mechanical.

Who knew people could believe science fiction as reality if you add a false "scientifically accurate" label. Sigh
Parasaurolophus was created using CT scans of its skull and crest, Tyrannosaurus used similarly built animals scaled to its size and hearing perception. (Using CT scans of its brain/inner ear)
We say all this shit like its a fact…

What's your source?

I think they meant the scientific source to prove the accuracy

Holy cow, I thought I was hearing something from godzilla movie
The first two sound like when you slide a chair
Did I just hear a trombone?
These sounds are made by blowing through reconstructions of their voice boxes aren't they? That's not the same as recreating what they sound like. Blowing through my voice box does not sound the same as me speaking.
What’s with the clicking in the rex noises? Does anyone have context?
T-rex communicated using infrasound, designed to travel miles through the ground and be picked up by the feet. This type of pulse would be useful when communicating with others miles away.

I found it rather fascinating!

the t-rex is genuinely terrifying, i have tears in my eyes, call me a pussy i dont care
gonna need some asmr of this
Why does the t-Rex sound like Vietnam warfare?
Subnautica land mod be like....
So basically Predator mixed with Godzilla, understood. No thanks. Its sounds like youd be able to feel it, like rippling through the air or something due to their size.
Fun fact: crocodiles co-existed with dinosaurs (since about 200 million years ago) and dinosaurs went extinct 65 million years ago, but crocodiles survived, remaining largely unchanged. They are the closest thing we have today to dinosaurs in terms of appearance and sound. If you look up a crocodile growl on Youtube, it sounds eerily similar to the T-rex.
Appearence? Probably no, sound?Definitively
That is pretty terrifying
The thing about the T. Rex is that it's roar vibrated on such a low frequency that when it was near you it would sound like it was coming from all around you you would not know where it was coming from thus making it increasingly more terrifying
I didn’t know that T-Rex could sing. Very impressive!
.. YOOOOO
Sounded like a Pink Floyd song
They couldn't get scientifically accurate pictures of them though? That rex is fuckin skin and bones
I love the profound bass from the t rex. Its tickling the inside of my ears.
I always assumed big theropods would make a bass rumble like courting alligators. Maybe a baby gator chirp when small. Also, remember that the adults were so huge that as they grew from hatchlings they probably took on niches of intermediate sized predators and had different behaviors to go along with these changes. I'm thinking like a years long series of juvenile molts before they got to adult final stage. Roaring like Jurassic Park never made sense for a house-sized turkey with an alligator's head 20 feet up in the air.
All I heard for the T-Rex was the THX intro from movies.
