An ongoing study utilizing the most recent scientific data on mammalian/reptilian vocalizations. Sounds are produced by myself and digitally workshopped from modern mammals and reptiles. Using modulated 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 unlikelihood. The final results are based on acute representations of what sounds would be most comfortable and base-line for each animal.

Method: Using a similar, but altered model to Julia Clarke's Mesozoic Tyrannosaurus Rex vocal 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), where they got was an ominous low rumble.

[@StudioMod]

The sound was actually recreated by blowing air into a recreation of the Mammoth's upper respiratory tract. I had help on that one. First link in the description. I still had to do work on it though, as it was for a Wooly Mammoth, not a Steppe Mammoth 🦣

[@robinator652]

​@@altithoraxperotorum5133most likely not

[@Fiftyfourthengine]

Unlike dinosaur vocalizations, Cenozoic animal vocalizations are kind of easier to recreate, especially considering how they look very similar to their modern counterparts.

[@originalname4701]

Agreed, extinct enozoic animals are a lot easier to speculate on what they may have sounded like considering many of these animals still have living relatives today.

But why is it different from elephants? Asian elephants are more closely related to mammoths than to African elephants.

[@The_Shwnk]

as mentioned in some other comments, mammoths had a different skull structure from modern elephants and thus wouldn't make the same sounds; these sounds were actually made by blowing air through a recreation of the upper respiratory tract of a mammoth. @@Aethuviel

The mammoth genuinely suprised me; im so used to just hearing modern elephant sounds come out of it in media, but conpared to an elephant's trunpet, this reconstruction sounds more like a trombone so to speak. So fascinating!

[@LuanMower55]

Look up a celtic cornus instrument. Quite similar in some ways

[@Lord_of_Proboscidea]

Almost reminds me of Far Cry Primal’s elder mammoths. They sound trombone-like when they trumpet, not like any modern elephants trumpet.

[@quantumsaudio]

idk why but the short-faced bear gave me weird chills. it's so close to our modern bear but it's off enough to sound unearthly and out of place. I'm so happy you're covering mammal-centric eras alongside the reptile/avian ones. This era is equally as interesting as it's part of our own ancestry!

[@YvieT81]

If this one gave you chills you should look up the bear scene from the movie Annihilation. That’s some scary shit!

[@garfieldenjoyer420]

I saw fossilized remains of one at a dig site/museum in Tennessee. Intense animals! Huge!!

[@80ki68]

I think that's just the vibe of this video. They're all creepy and alien, but IRL they would probably just sound like normal animals.

[@maggiiopgott8975]

It might be because humans naturally competed with them for caves

[@jacklantern7479]

I remember debating someone on whether or not our ancestors would be more screwed to encounter a SF bear or a gigantopithecus, I think that bear growl solidifies the horror

[@safron2442]

It's hauntingly beautiful how much the steppe mammoth sounds like certain Northern Eurasian music/horns. If that is what they indeed sounded like, I wonder if it's possible that our ancestors originally heard the mammoths and went to recreate it- and those recreations survived into the modern day, unlike the species they were inspired by.

[@TRUTHANDCONSEQUENCESWILLNEVER]

Not a chance

[@thecrepeofdeath]

@@TRUTHANDCONSEQUENCESWILLNEVER oh? do you have evidence disproving this theory, then?

It’s seems more likely that for this video, they would’ve used instruments like those horns you mentioned to create the “sounds of the animals”. All of this is very hard to believe since there was nobody there to tell us

[@safron2442]

@@n1ghteng4le No one saw dinosaurs alive but we know a great deal about them due to things like fossil evidence, and sound reconstruction is very possible for certain species.

One of the best so far, I swear if a studio doesn't hire you for sound effects it'll be one of the biggest missed opportunities of the century. As a megafauna enjoyer, I am hoping that one day genetic research advances enough for us to make some of these species re-evolve, like all mammoth species or the glyptodon (kinda wishful thinking on that one haha). Keep it up man, I hope you can continue your research. ¡Siempre adelante!

[@Tyrexthecreaturedesigner]

I love all of these. I’ve always wanted to hear accurate mammal noises. The mammoth is honestly terrifying. Sounds like the soundtrack to a tribal jungle type film or video game

[@happylilfrog]

The pic of the woolly rhinoceros is so cute/majestic.

[@StudioMod]

You would not imagine the tremendous effort it took to find a good one. Nearly 5 1/2 hours of searching then editing out the background.

[@LB-yh8cl]

Since these animals are a bit more close to us than the dinosaurs, it’s possible they sounded like some of their alive cousins, but bit of alter distinct differences of sounds they make

[@gutemorcheln6134]

Dude, these animals went extinct only some tens of thousands of years ago. Not at all comparable to how long the non-avian dinosaurs are gone. 10.000 years may seem like a long time, but it's actually just the blink of an eye in evolutionary terms. The world's ecosystems are still out of balance because of the human-induced megafauna die-off starting then and continuing to the present day. And of course they would have sounded like their remaining relatives. In order to reconstruct the sounds of wholly rhinos, your best hint is the sounds the sumatran rhino produces. For mammoths, listen to Asian elephants. Short-faced bear? Spectacled bear. And be glad they are still with us, because judging by how we keep destroying the planet, they won't be for long.

[@yoshidracos.a.1125]

It really pleases me that some of these reconstructions due feel like their modern counterparts, yet, still feel like something that hasn't been heard before. The Steppe Mammoth one? Oh man, felt like hearing a ghost. I love it.

[@florpleborp2275]

Absolutely stunning video. The mammoths first vocalization was so different and unlike any elephant noise I’ve ever heard, and yet it felt so similar too. I loved that each creature wasn’t a carbon copy of a real life counterpart but slightly distorted, they were actual sounds that the animal could logically make based on our understanding. If I could suggest anything I would love a description of the vocalizations, like a T.Rex’s mating call, or a terror bird threatening call
