Extinct Marine-Species Vocalization Study

[@StudioMod]

*For anyone wondering about how I decided on the Leedsichthys sound:* I made the creative decision that Leedy here would vibrate his swim bladder and generate a gentle, low frequency hum like the modern Porichthys notatus, which are surprisingly loud little guys. Upscaling that concept resulted in a low frequency drone that would likely travel some 15-30 miles underwater.

@@wanderlustoceans8205 to be fair we need a more complete skeletal frame to do it, we would have to figure out the corporal build, and guess how the internal body structures aid in its acoustics, hence the fragmentary remains of Maip and the relatively new discovery of it is not really too viable for this

[@hunterkillerxyz]

With the exception of the prehistoric cetaceans, it’s completely possible that most of this giant sea life didn’t make any noise at all in the water, which makes them even more terrifying. Imagine one of those giant sea reptiles just snatching you with no warning whatsoever only the splash of it’s breach and descent as your dragged into darkness

[@StudioMod]

Like I said to someone else a moment or so ago, it's likely that most of these reptiles-based ones were fairly quiet, but I focus on trying to capture their ambient noise: air chamber and pressure shifts... that sorta thing. Still, this is just an estimation of what they would sound like IF they made sound. With that said, the Colossus and Livyatan are likely very accurate considering they are mammals and I can fairly accurately arrange what they would sound like since they have very modern descendants.

[@Flufux]

To be fair, reptiles do make a lot more noise than a lot of people think they do.

[@greninjaguy5264]

I still know that the reptiles would pronbably produce some booming guttural sounds that can emenate through the water, akin to alligators and crocodiles bellowing, for either territory disputes or mating.

[@spectator3308]

[@marcgarrigosmane166]

But idk if it's realistic. Basilosaurus was a whale. Probably it would had sounded like today's orca

[@BinroWasRight]

@@marcgarrigosmane166 Orca are the largest dolphins. And basilosaurus was a very early whale with a very different body plan than modern cetaceans. I'd be surprised if it sounded like an orca, a baleen whale, etc. 🙂

[@Aethuviel]

@@BinroWasRight Humpback whales and killer whales sound more similar to each other than this thing does. All whales (dolphins are whales) squeal. They produce sounds with their blowhole. Since Basilosaurus lived around the same time that toothed and baleen whales split, there's no reason it should sound like anything other than a large modern whale.

[@witchflowers6942]

@@Aethuviel​​⁠​⁠​⁠no that’s extremely unlikely. Basilosaurus was wildly different from an orca. Orcas are dolphins. No living cetacean is similar to basilosaurus. Basilosaurus was originally mistaken for a reptile not because early palaeontologists were stupid, but because it’s skull and bodily plan are distinct from known cetaceans. modern cetaceans may have comparable vocalisations, but we can’t necessarily extrapolate that to such an ancient species. Basilosauridae was the first group of fully aquatic cetaceans that we are aware of. Basilosaurus did not use echolocation. It did NOT have a blowhole as you have asserted. It had two nostrils at the end of it’s snout. Basilosaurus was more like land mammals that its modern counterparts.

[@Lotan_]

@@witchflowers6942 Interesting how the body plans of Basilosaurus and the surviving Cetaceans seem to refect those of Mosasaurs and Ichthyosaurs. Makes me wonder what the oceans would be like if Basilosaurus had survived and diversified.

[@cassidynoelle741]

Has there ever been any similar research done on the vocalizations of extinct hominids? I wonder if they would sound more like us, more like our closest living relatives, or somewhere in between. Can you imagine how cool it would sound if one of these species of people had some form of rudimentary language but vocalizations more in line with great apes?

[@StudioMod]

That's actually so advanced that I wouldn't touch it personally. There is probably ways to actually rebuild their soft tissue organs with the right team and specimens. In fact, that sort of thing has been done before in small doses, so I wouldn't waste my time on it since something very similar and more accurate will likely come about in time.

[@blademaster4361]

That sounds fascinating, actually. Considering that most hominids lived for far longer than humans have been around, I can hardly imagine how many early languages could have come and gone.

[@lesserdad]

Ive seen neanderthal reconstruction of speech. most other hominids did not have the right vocal cords for speech like we have

[@LurigaBusungenHans]

What if you’d take living animals, and try to recreate their sounds in the same way that you recreate these sounds. Then we’d be able to see how accurate this method is, which would give us a good picture on how accurate these sounds are!

YOU are the first person to say something like this. I DO do that already and this is how I figured out how I could learn Julia Clarke's method. You have a good mind.

[@gaylordhardick9994]

I THOUGHT I WAS THE ONLY ONE WHO HAD THOUGHT THAT. I was imagining and I said to myself, Why not have a group of paleontologists and scientists estimate the real appearance of some actual animal of which they have no knowledge only with their bones and fossil record (if they have it) with the same methods just to see the degree of effectiveness they would have ? (This would be very difficult since these scientists would have too much knowledge about actual animals). But your idea is way much better and unlike mine, scientists are more likely to be unaware of many actual animal noises than their appearance.

[@XSR_RUGGER]

I thought the same thing along with people who reconstruct faces. I always wondered if they had some sort of control with a provable source material.

[@jaymikevillanueva1212]

The method you used is a very logical step to giving us an idea for what these creatures sound like. Each one is pretty haunting and unique in their own right. And it brings us to this one simple conclusion: the prehistoric seas were truly a horrifying place to be. Excellent work. Keep them coming at your own convenience!

[@yoshidracos.a.1125]

Gotta give it to the Basilosaurus and the Livyatan for favorite sounds (honorable mentions being Cymbospondylus and Liopleurodon). But Basilosaurus really sounds like a primitive whale. Doesn't exactly sound like a blue or humpback yet it feels similar, and then you got the Livytan which lowkey sounds like a Sperm Whale on steroids. That's terrifying.

[@Rusted-studios]

That’s because it did not have the right thing to make the sounds of a whale

[@faultyblender3590]

To be fair, that's exactly what Livyatan was.

[@DracoJ]

The mosa is terrifying, it almost sounds like its speaking, but i can tell it isn't. I never expected these roaring esque sounds from a basilo considering they are usually depicted as ancient orcas. But then again i don't know much about the vocalizations of orcas. Very cool.

[@beanoptodon]

Mosa reminds me of Orca vocals as well, since they can make weird almost-speaking noises too!

[@ethoatom668]

It's interesting that despite none of these being the deep roars you'd hear people give to fictional sea monsters, many of these are, in a way, more haunting/unnerving. Like Cymbospondylus', it's these high pitch trills, yet if I were in the ocean and heard that sound in the open ocean, knowing that it's connected to something that huge, and with the echo, I think I'd be freaking out. Also, I honestly take for granted how ancient seas were likely filled with noises, many unfamiliar to me. So, I love this video in particular.

Leedsichthys legit vibrated the lower half of my entire body. I can't explain or describe it but it just felt.... Felt like it vibrated everything from my feet up to my hips. I have no idea why.

[@itsameah2595]

That’s probably accurate to how these vocalizations actually worked. Like with a lot of marine mammals, most complex vocalizations are on a frequency we wouldn’t be able to hear but we could feel, especially underwater where sound waves travel further. Most of these creatures would have vocalizations you would feel rather than hear.

Yo. Imagine if you just were at night underwater and you heard the leedsichthys sounds in the distance.
