What Did Dinosaurs Really Sound Like?

When you think of dinosaurs making sound, you'll often think of Jurassic Park's classic Rexy victorious roar. However, science has sided with dinosaurs not taking this route for vocalization. Even the tyrant lizard king had a completely sound than what has been depicted in common media. So if you ever wondered what did dinosaurs sound like then you are in the right place!

Just a couple of corrections for the mis-wording I put in this video. 1) For t.rex and bird ancestry, I should’ve cleared that up, birds are their closest relatives. 2) The artwork at 0:42 is by Fred Wierum. 3) The BBC itself isn’t accurate but has the funding to get expert opinion.

That may be part of why we experience an intense sense of fear when hearing infrasound; behavior passed down over millions of years (as there are still animals that make that sound, ex: alligators and crocodiles, so maintaining it in some areas would make sense).

[@stoffni]

@@kyze8284 A theory of the T-Rex is that it was an ambush predator, because of its large size, it is seen as unlikely that it was a dinosaur that was actively hunted. The theory is also that they were deadly silent even for their size. You'd think you would notice when it would walk but you wouldn't. Basically, you wouldnt know it was there until it had you in its mouth.

[@kyze8284]

@@stoffni I was saying the rumble as the vocals as that’s what the entire video and comments are about I’ve seen bears and even moose stalk through trees. A large ambush reptile with similar padding would make so much more sense than running down prey too, like what we imagine Carnos might have done. Cause a stampede towards others of the group who then ambush and take down prey from a set point on the escape path

[@Outland9000]

Low frequency sounds are less directional than higher frequency (as far as I know) so it might be hard to tell exactly which direction it's coming from, and you'd probably be able to hear it from a long way off, if you can feel it in your chest it might be close, very close.

You’re in a tree nest looking out over a clearing and all of a sudden a dozen deer fly out of the trees to your left and across the clearing and out of sight. It gets quiet for a moment. Then you hear, no, feel this sound through your body. You scan the trees wondering what the fuck is going on but see nothing out of the ordinary. You hang the bow over your shoulder and grab your binoculars but it’s getting dark and with a gentle breeze flowing through the forest, you cannot discern movement. In your growing panic you think about scrambling down the tree and to your atv, after all, the others back at camp aren’t that far. But before that thought completes the wind dies down and you listen. Everything in the woods seems to hold its breath.. all but one. You hear a steady inhale. Then an exhale. You scan the forest once again with your binoculars. The radio cracks and a branch snaps. You turn the radio off and peer into the darkness. From behind you hear the sound of a flare firing into the sky and then you see them. Two eyes ten feet off the ground staring back at you, unmoving. The glow of the flare dies and the eyes vanish. A scream sounds in the distance.

I think that was mostly used for mating and conversing with younglings, there is no reason to scream at prey. If T-Rex wasn't a silent killer, walking slowly and methodically, it wouldn't reach the back of the neck of a Triceratops. It would probably run pretty quick in extremely short bursts as well, due to the mass. Like a crocodile, just sitting patiently, quietly, until the sudden snap.

Media cant even accurately get existing sounds right, for example, eagles (and many birds of prey) often use the sounds of hawks, the iconic "eagle screech" is from a red tailed hawk. Lions also often get vocalizations from tigers. It's easy to get the depictions of dinosaurs wrong compared to that (and at least to jurassic park's credit, the dinosaurs there aren't "real" and were apparently stated to purposely be engineered based on the pop culture depictions of the time). As stated at the end, it's easy to be wrong in an ever-changing field where views and opinions are always clashing.

[@kyze8284]

To be fair, a Golden Eagle and Red Tailed Hawk do sound eerily alike. Using it for a Bald Eagle however, that usually chirps, is always annoying. Not even going to mention it being used for MOSTLY SILENT buzzards

[@RavenVI]

@kyze8284 I mean, I guess. I wouldn't really call it annoying though, it's a lot prettier sounding than the seagulls people compare it to. It's a "sea eagle" after all, it makes sense for such adaptations to occur. Trying to humanize what does or doesn't sound cool in nature is dumb imo anyways, since they take function over form.

Imagine this, you're standing in a clearing and something shakes you to the core before you hear a strange, muffled, almost inaudible rumble, you look around as you and see nothing as fear slowly creeps into your mind. After a while of looking into the surrounding forest, it happens again, this time even more intense before hearing that rumbling, this time closer and you freeze as a deep, primal fear takes over. Then you hear a soft thud and then another and another along with the sounds of rustling leaves and snapping wood, your eyes frantically scanning your surroundings, as you realise that these are the steps of something big and after what felt like hours, a gigantic predator emerges from the foliage, its mouth barely open, immediately letting you know that it is the source of the rumbling, as its throat vibrates, shaking you to the core with calls partly below your hearing range, unheard, but not unfelt. It briefly glances at you with piercing, amber eyes before continuing its march across the forest. As it steps away, you notice that you are shaking, your heart beating faster than what you thought was possible and slowly and steadily, you relax, one muscle at a time as you ride your motorbike to safety.

Been looking into this kind of stuff for a project of mine. Fascinates me to see what people think they may have sounded like.

[@danielhavoc889]

If you guys havent check some of the full videos on the realistic Trex sound, as whats in this video only scratched the surface of how terrifying the sounds are.

[@ososkid]

I am perfectly happy to hear these sounds with the understanding they may not be right at all or they may be close facsimiles and we are unlikely to ever know. I’m just happy we ask these questions and come up with answers

[@swancrunch]

love the T-rex rendition, straight outta horror movie. imagine hearing that sound resonating in you guts and thinking "oh! there's a T-rex somewhere in five mile radius" although i have to add - there's a distinct high freq cut as an artifact of slowing down a sound, in reality it likely has more high freq info in the signal. like a saussaphone from hell, or a diesel engine on low rpm.

[@Raelven]

Even the tiny western fence lizard can make an impressive hiss. I can only imagine what an eight ton relative sounded like.

[@dyliera.velazqueznidoknigh6089]

That T-Rex low frequency would just make your bones vibrate and your bladder leak. You can just feel the power. You won’t get a fight or flight response, it’ll just be freeze.

[@JP-xg6bv]

JP rex does sound scary, hearing that in the wild would make one fearful but still functional. However there's just this indescribable feeling deep down in my gut when I hear the real thing. It's just scarier in a way that words can't describe, an instinct or a reflex more than a thought. Certain types of tiger roar frequencies can paralyze one with fear due to the audio/physical frequency combo. I imagine a real rex would affect a human even more severely

The Parasaurolophus sounds pretty majestic if you ask me. It fills me with awe and wonder. Maybe I just don't get something, but I heard the rumble at the museum that they think T-Rex likely used and I have to be honest the rumble just doesn't scare me at all. To me the JP roar is much more frightning.

[@wolf_pd]

The Parasaurolophus sound made me think of a carnyx.

[@corvidcorax]

Somebody else already said this better, but if you listen to the T-rex sound with good subwoofers, you'll notice that it's more of a low frequency rumble. IRL you wouldn't just hear it but you'd feel it in your bones, and the worst part is that it would sound like it's coming from every direction at once. It also doesn't help that it sounds alien. We already have modern animals that can roar like lions but I don't know of anything that sounds quite like T-rex.

[@NerfMyEpeen]

Going to have to agree with you, if this T-Rex sound doesn't terrify you, you either lack imagination or experience around animals that could casually kill you. You're missing something.

[@coreym162]

I imagine that T-Rex less intense version is like you did something deathly wrong to hear that and by the time you turn around to try to see what you did wrong it eats or mauls you to death. Far creepier than any Hollywood depiction.

[@Curry_Cardinal]

Honestly, I like the real noises more than the ones from the movies. It’s interesting to know that they didn’t just roar, and they could make a variety of different noises. Hopefully one day we’ll be able to know exactly what they sounded like, and how they communicated.

I really like Studio’s take on what they sounded like. The trex is the most terrifying yet hilarious rendition I’ve ever heard. One minute it sounds like a giant goose, next it sounds like an alien war machine.

[@RowanRabbey]

The slowed down loon being passed off as spino made me think that the whole "slowing down a similar/related animal's sound" for dino audio reconstruction seems pretty bad for confirmation bias start to finish, even if it produces believable results. Take the preserved ankylosaur's larynx - which we only got bc it was mummified - and imagine if we'd never found it.. we'd probably be making ankylo vocals from like armadillos or turtles. Even the tyrannosaur sound just assumes that the vocals can be pitched to scale with the animal it's recreating, which just doesn't physiologically pan out with anything other than vocalizations close to a sine tone (and even then the overtones don't match, like the tiger/cat video) bc of square-cube law and flow dynamics across those larger surfaces. Going back to spino; it'd be interesting to see an actual reconstruction of their possible vocals, especially given that the retracted nostrils and smaller antorbitals would give them nasal resonances different from basically any other theropods.

[@Aragorn62]

That low rumble would vibrate right through your body and not knowing what direction it was coming from would be very unnerving! Definitely asbestos underpants required in that scenario 👀

[@apersunthathasaridiculousl1890]

The Parasaurolophus sounded terrifyingly majestic

[@user-ok8uo7sn6i]

The sound of the parasaur actually fits it’s look

[@dr.pepperbiggestfan]

the trex vocalization is surprisingly relaxing. the weight of the rumbles reminds me of a cats purr, obviously louder and deeper, but that same sensation of being vibrated all the way through. the deadliest purr ever

[@damotoneko1500]

What i find cool is that the T-rex's roar and rumbling steps make sense in Jurassic Park. Because it can't see movement it roars to startle it's prey. But if it could roar with the vibrations and depth of these sounds in the video it would definetly make the Spinosaurus turn tail at the first encounter.

[@Brakvash]

turns out the movie was wrong and the eye-sight of the T-rex could have been as precise as a hawk, if not even better cause T-Rex eyes are 100 times bigger.

[@neowolf09]

[@KaneyoriHK]

I feel like louder noises could be produced in a territorial setting or warding off, but general communication among other things would be the low grumbles. Many animals do as such.

The segment with pinacosaurus potentially chirping made me think of the kinds of high-pitched squeals that rhinos produce! And the variety of vocalisations they make, as well. While they're obviously not related to the pina, there are some comparisons between them and rhinos, with both of them being several tonne herbivores with hard weapons on their bodies. It's fun to speculate :o) Fantastic video!

I have always had a weird obsession for the noise a crocodile makes. The way you can feel it reminds me of thunder that makes me giddy af.
