- The Prehistoric oceans were bubbling with leviathans toothed predators almost the size of whales were common place up until fairly recently. The ferocious creatures that used to inhabit the oceans are well known about, however, what was the deep sea like during these times.

I recently thought about the fact that, had the coelacanth gone extinct just 100 years before it was described, we’d have never known it survived the mass extinction because it’s impossible to get deep sea fossils from so short ago
There is a fairly recent doc about them filming a coelacanth with specialty diving rigs.
I never thought about that before. Makes me think: what other deep sea animals are thought to have gone extinct long ago, but potentially survived until fairly recently? And what could be possible ways to know about this?
@@UATU. you can’t do that if it were extinct
@@solgerWhyIsThereAnAtItLooksBad They aren’t extinct.
@@UATU. that’s why I said had they. Do you not know what a hypothetical is?
Long time no moth. Welcome back!
I have been searching for a video like this for years. I am so happy to finally get to learn about this. I struggle with reading academic papers so RUclips has been my only option to learn this stuff. Thank you so so much this has made my day
Your videos are not only extremely soothing (i could use them to help me sleep, and by that I don't mean they're boring !) but also very informative.
My main topic of interest is insects, and I didn't get much of an education in paleontology. While I don't really study ancient organisms, being aware of ancient evolutive trends helps add context to modern ones. Thank you for doing that !
I remember 15 years ago in college doing a presentation on Osedax in front of the class. By that time the info was scarcer and it had only been tested on cetacean and cow bones, but we already ventured the idea of its origin as a scavenger of Mesozoic marine reptile carcasses based on mollecular clock data. Glad to hear we were on the correct path!
Love your videos BTW
We always talk about how many land animals well never discover due to how rare fossilization is. Imagine all the sea fauna that stayed in the abyss and never got persevered.
yeah , we really can only speculate about the diversity of life down there.
Another amazing video! This is my first time hearing about Phosphorosaurus and the Sundance Sea, so cool!
With the amount of unknown curiosities and mysteries in our deep Oceans alive today, that we haven't discovered yet; I can only imagine what wonderfully weird and amazing animals have been living in the deep dark Ocean for the past half a billions years!
Two uploads recently? What a pleasant surprise!
But the music is back...
@@hornetscout2579the music is a staple
indeed!
Don't ever change your format 👍
Thank you moth light media, I’ve been enjoying your content for about 2 years now. I gotta say your quality and researched is unmatched in these bite sized videos. Absolute perfection
I'ma watch this tonight while I go to sleep, I absolutly love your videos and they never cease to make me sleepy. :) Love you mothlight!
I'm so pleased to see this channel start to gain influence. It's a rare treasure on YT and needs greater exposure. I've learnt so much from it and now have my nephews hooked. Thank you Moth Light Media; may you grow and receive the recognition you deserve.
Especially with the clickbait corruption of extinctzoo, ive been an mlm fan for years, such calming content
Awesome, thanks, i never thought about this, but makes perfect sense.
Imagine roughing it up on crocodile scraps for 20 mill years to properly feed again
information about the deep ocean always fill me with awe and fear
Oh my god i just realized the absolutely absurb amount of fossils currently hidden underneath the seafloor
Less than you might imagine because the basalt from oceanic plates is always shifting and most often ends up sinking back into the earth's mantle, unlike continental plates which are made of mostly granite which is lighter and keeps floating on top of the mantle.
Good point. There's at least a dozen or so...
Weird I was just in a moth light media Marathon today and it ends with a new vid! How funny
I love your content so much dude, you always bring up such interesting topics that lack discussion. I was literally thinking about this very topic on Monday as I was doing museum prep. I hope you know how much of an impact this channel has had on me as I’ve studied geology and explored the ancient world
I love how informative and detailed yet concise moth lights videos are. Long may this channel continue!
Yes new moth video

INTRO´S BACK YAY :D
THIS IS SO COOL! Thant you so much for bringing light (pun intended) to paleontology I knew nothing about!
Your videos brighten my day God bless you good sir
I love how the squid footage is just chaos, very on brand
I like the original music of the videos
Thanks for another fascinating video.
Saw the title and my thoughts immediately went to something I've thought about so many times before. The deep sea is filled with all manner of strange creatures we've only recently discovered, but what kind of evolutionary history do they have? Just how long have they existed there? Have they existed for many millions of years in an environment that's been relatively stable and virtually unchanged, or did they evolve more recently, in which case, what might've existed before them? o.o
I can't imagine deep sea dwellers left behind much of a fossil record, so we may never truly know the answers to these questions...
fr fossils in the deep sea. This makes me wonder what would be the most surprising discovery about it if we could access their evolutionary history
Great video, I love your voice, it’s calming and relaxing
Wake up babe, new moth light media dropped
Beautiful video. the theory about different organisms feeding on different marine carcasses is fascinating.
Thia is a fascinating! I'm really interested in prehistoric marine reptiles. This is the first video I've seen about the topic of the deep sea. Your videos are always good. Also, as a voice over artist myself, I love your voice. It's one of the reasons I've been a big fan for a long time. I'd love to voice a great science channel like this. Thanks so much.
Im glad the intro and the bg music is back 😁
My favorite type of video - the prehistoric sea.
Your videos are very well made and relaxing, thanks for sharing.
''crocodiles washing out''.....my fellow sea turtles never went away.
Ive always wondered the fossils that are under the ocean. Once we find out how to discover them and get them imagine.
Your videos are informative and entertaining, thank you so much for doing what you do!
You are awesome
I had no Moth and I must scream
Probably scary and dark, like it is now
great video!
BABE WAKE UP MOTH LIGHT MEDIA POSTED
smooth voice
Great vid. 🙂
Cool video, I never even thought of this topic. Scary stuff
it was a bit wet i imagine
Probably had fish in it too
Amazing video!
Yet another enlightening and calming video to sleep to or study
Yo I've never been this early I'm so hyped!!
I don’t know if marine reptiles could go into the deep without echolocation. Also do the rest of their bodies suggest deep sea adaptations? Because the deep sea compresses the body.
I think marine reptiles in ocean depths rely on other adaptations like keen eyesight or potentially other sensory mechanisms rather than echolocation.
What I find increasingly terrifying is that practically all (at least to my knowledge) of marine fossils discovered are from shallow seas. Oceanic fossils are, obviously, not only all the way out in the middle of the ocean under thousands of feet of water, but also are constantly getting ground into the conveyor belt of subduction zones because the basalt plates are heavier and sink under the continental plates. If what we've seen is only barely scratching the surface of what was in shallow, temperate waters, i shudder to imagine what horrors dared to brave the deep open ocean
I really enjoy these videos thank you and a very interesting question to explore.
Love this guy
Cool
The part about air breathing creatures having an advantage in the low oxygen environment explains something that I have wondered about: when terrestrial animals returned to the sea, why didn't they re-evolve underwater breathing? Returning to the surface means interrupting their other activities.
There’s no doubt in my mind that some truly incredible albeit horrific creatures lived and died throughout the ages in the deep sea… Personally I believe there’s _still_ undiscovered nightmare fuel down there.
Case in point, we still don’t know what ate ‘shark alpha’ in 2003… but it certainly wasn’t another great white (that theory has more holes in it than a block of Swiss cheese lmao)
Apparently the researchers themselves bet on it being another great white. That would also be my best guess.
A killer whale?
@@spoopa7733 that would also have been a good guess but the researchers seem to think it was another great white, which also seems plausible
Awesome!
I love crinoids ^.^ Cradily is the best fossil pokemon, and my fav
abt to love this 11 minutes
We
Good vid
I don't know who you pissed off at RUclips but despite being subscribed with notifications turned on, I do not receive notifications when you dropped a video. I used to, but it's stopped happening.
The crinoid thing isnt exactly true. Extinct species used to live in pretty much every habitat you can think of, some even anchored to driftwood at the open ocean's surface
Its only the modern species which are exclusively deep sea, and in that sense is very similar to other formerly abundant "living fossils", such as nautliuses, coelacanths, and monoplacophores
no way while rham sighting
I saw a skull where there was a flattened ring of bone inside the eye. A very large eye. We were told it was to provide support against the pressure of deep dives. Mosasaur, maybe, saw it 15 years ago in a museum.
I love this topic
LOOKS LIKE INTRO IS BACK ON THE MENU, BOYS!!!
Another huge problem regarding deep sea fossils is how frequently oceanic plates are submerged and recycled with the tectonic of plates, there are pieces of continental crust billions of years old but at most you can have a piece of ocean floor from the middle of the Mesozoic
0:47 that fossil looks exactly like a face hugger from Alien
Off topic, but marine reptile directed:
I was wondering for a few decades how plesiosaurs could exist in oceans prowled by much larger, toothier, predators. Returning to that question during your presentation, I could see the utility of cooperative hunting; such as several plesiosaurs surrounding and confining a bait ball, while each in turn swings his/her head into the bait ball to grab a snack. No great flexibility required; just a slow swing back and forth. The head, alone, is about the size of a bait fish, adding to the efficacy through inadvertent mimicry.
The plesiosaurs don't need to actively team up. As with crocodiles and a few others, merely keeping a small interval between the predators acts to everyone's benefit.
Do you think there are modern marine animals that exhibit similar cooperative hunting strategies?
@@AncientWildTV I do.
I like this moth guy!
I WISH more video game developers would collaborate with archeologists & other scientists that study prehistoric life. Then they can work on projects that utilize video games as interactive experiences. In the 90's i played educational computer games that utilized visual design to help teach you about the different biology that has existed on our planet. There's so much potential in this field that is not being used.. i hope that changes soon
The moment there will be money to be made, it will happen. Profit overrides everything.
@@marrs1013 *the moment they bother to do enough market research to realize there is a mostly untapped market you mean.
@@Sara3346
No, I did not. I mean when they figure out how to fill it with micro transaction, DLCs, pay to win features, and generally how to make it plain addictive, than they will do it.
@@marrs1013 But none of that is actually needed to turn a profit 😞
@@Sara3346
But nobody wants 'some' profit. If you not constantly increase and maximize your profit, you are failed as a manager, and will be replaced. The main investor are hedgefunds, and therefore the board would rather accept a higher risk of failure for a higher promise of profit, than moderate profit and a good, educational, long term product. Just the reality of businnes today. When the investors are profit oriented corporations themselves, driven for nothing but ever growing and maximized profit instead of human beings, this is the outcome.
Is fossilized sea floor necessarily of shallow water? Or could the abyssal floor have surfaced in the millions of years that have passed?
Depends, but most marine fossils come from areas within the continental shelf
lets gooo
Abyssosaurus seems to me like counterpart to modern beaked whales. I wonder if we ever discover plesiosaur that convergently evolved size and lifestyle similar to that of sperm whale.
Subnautica episode!
Can you put the song name in the description, thanks.
I think the giant eyes were an adaptation to the fact that they lacked echolocation. 🤔
The specialist deep-sea cryptoclidids really need more attention in paleomedia.
These are questions the hood been pondering 🔥🔥🔥🔥
There are some strange creatures in the ocean. We might still find more. 😳
Imagine explaining rest of the university's fields of studies that the university funds went into sinking alligator corpses in the sea to prove that worms ate dead mosasauruses
How do they find the carcass' in the vast desert of the deep ocean floor? Are they lying everywhere dormant or are they brought there by other predators?
wohooo!

If only we had machines we could send through time, that could last millions of years and record all that time in between.
Natural history students and professionals should know that the most significant evolution happened within single cells from which life oriiginated.
A new book published by Austin Macauley Publishers titled From Chemistry to Life on Earth outlines abiogenesis in great detail with a solution to the evolution of the genetic code and the ribosome as well as the cell in general using 290 references, 50 illustrations and several information tables with a proposed molecular natural selection formula with a worked example for ATP.
The author concludes that eukaryotes are a product of both a proteobacterial invasion of an archaeon and a subsequent invasion of that symbiont by a cyanobacterium with a subsequent loss of photosynthesis genes in animal protozoa.
Very mysterious and hard to study, because trenches are often subduction zones.
0:49 what is that a fossil of?
It’s another sea lily
The creature
A kind of crinoid, most likely a sea lily or an ancestor thereof
the great old one
@@alfredwaldo6079a hunter tips his hat for a fellow hunter
feels like Eons since you last uploaded
Thinking of abyssal plesiosaurus is terrifying
Yeah, all these people commenting that this helps them sleep must have shut their eyes or turned away from the screen by the time the red Abyssosaurus and its fangs appeared, because that’s genuine nightmare fuel
No mention of the Paleozoic?
I imagine it might have been hard to find info on Paleozoic deep sea fossil sites. There are actually a couple deep sea fossil sites from the Paleozoic, namely the Ordovician-Silurian Yaman Kasy hydrothermal vents (check out the paper "Microbial-tubeworm associations in a 440 million year old hydrothermal vent community" for more info) and the Devonian Hamar Laghdad hydrothermal vents (check out the paper "Discovery of thermophilic corals in an ancient hydrothermal vent community, Devonian, Morocco" for more info) which is believed to have likely been in the aphotic zone.
@@GoodrichthysEskdalensis Agnostid trilobites come to mind
@@thedarkmasterthedarkmaster I remember reading a paper somewhere about a fossil site with blind trilobites that was likely deep water.
The OCEAN is 😢,though 😱 Moth Light Media have you watched Joseph Prince Ministries?
W
Maybe the Loch Ness Monster is a deepsea cryptoclidid plesiosaur that managed to hang on since the cretaceous (sounds ridiculous, but plesiosaurs were around for over 130 million years so 65 ain't to much of an extra stretch). Also geographically matches this clade
Osedaxes sounds very fascinating to think that they will be so specialized as to consume the bones of a specific class of animals these unique animals may even predate the Ordivician period
there's also the thing that things in the ocean floor eventually end up in volcanoes instead of buried
It should not be undervalued that almost all of the
Brainlet take. The deep sea has been thoroughly mapped, and the vast majority of species in it have been discovered. Deep sea ecosystems and animal sizes can be reliablly predicted by taking into account nutrient scarcity and water pressure
dude chill out.
Go research it then.
This is mostly because there usually just isnt anything in the ocean. Its mostly just empty space
AMPHIBIAN PLOP!
It probably looked a lot like that space between the wall and the side of the bed in a Discord moderator's bedroom.
Your mic is set too sensitive thus making plosives in your speech too poppy, which triggers my misophonia. I'd love to watch your interesting videos!
