15:55 and so is true for the blue whale. It's unlikely that humans discovered the biggest blue whale to ever live. It's important to keep that in mind.
We can measure the average length of blue whales from thousands of individuals, as well as the few exceptionsally large ones, the 0,1 percentile. Yet we only have remains from s handful of individuals of the few species we know,. The most likely chance is that those remains are from close to average individuals, while those top 0,1% that we have seen in blue whales haven't been found. Ofc, there could have been even larger blue whale individuals that we haven't seen, mostly in the past. But thebig sample size we have make it very difficult that any specimen would have been extraordinarily larger than the ones we have already seen.
I dunno about that. Whalers killed roughly 98% of the entire blue whale population at one point. If we didn't discover the biggest blue whale to ever live, we probably discovered specimens that got pretty close.
Don't you just LOVE the fact that we will never be finished in our exploration of the Earth's animal life, whether in the present day or in times long past? I think it's wonderful that there is still so much to learn, and that we are learning as much as we are. Well done, paleontologists! --N
Large extinct animals tend to be overestimated in size by paleontologists. So it feels more like the Icthyo fans forgetting that their new contender for the blue whale will almost certainly be downsized.
One thing I'm surprised no one has mentioned is that if the dental and jaw fossils are similar to other ichthyosaur skulls found in the past this animal could have potentially been the largest marine predator ever, regardless if it "dethrones" the blue whale.
That all depends on whether or not you consider baleen whales to be predators. IMO filter-feeders are just a subset of predators who happen to consume large groups of smaller prey instead of larger individual prey species.
Ummm sorry to burst your bubble but the blue whale *is also* a predator... However, if you correct your statement to "macro-predator" you won't look like a 🤡 who didn't pass high school biology lol
@@patreekotime4578Biology isn't "a matter of opinion" lmao baleen whales *are predators* whether the OP "considers them to be" or not! 😂 That's why the term "macro-predator" exists, to distinguish active hunters from filter feeders👍

The evolutionary explosion of ichthyosaurs is absolutely mind blowing. The more I learn about ichthyosaurs, the more they intrigue me. It took them only *one* million years after the permian triassic extinction to become fully pelagic marine animals.

My problem with these estimates is that both species they used for the scaling are very small headed and serpentine, potentially making the end product a lot more sensational than it actually was.
Yea I’ve seen this same song and dance many times, the estimate is almost without doubt significantly larger than the actual animal was. Paleontologists love to overestimate the sizes of specimens because it brings more eyeballs and attention to their work
I think at this point it might be more appropriate to say there was no singular "biggest animal of all time", but rather, these giant ichthyosaurs, blue whales, and sauropods represent the maximum conceivable size limits achievable by any living organism on Earth.
'Any living organism' is a bad choice of words here if you want to see big animals. Even a relatively modest giant sequoia effortlessly outmasses even the largest of blue whales or sauropods. They, in turn, lose out to mycelium networks in which a single individual can reach over an area of more than 10 km2. They, in turn, lose to some aquatic plants that grown massive forests consisting of only one single individual. The biggest example is around 180km2 in area, though I can't remember a mass estimate. If it is anything less than thousands of tons I will be absolutely confused.

Since filter-feeding is more efficient than active hunting, it makes sense that the largest animal of all time should be a filter-feeder, which is the blue whale in this case. It is very hard to see an active hunter to be the largest of all time without having its prey to be equal, if not larger than the hunter, due to the evolutionary arm race between predator and prey
It could very well be a case of indeterminate growth. They just grow until they can’t sustain themselves or become structurally unstable/incapable of feeding
In the miocene, macropredators (livyatan, megalodon) were bigger than filter feeders from what I've heard. Also, not all oceans are created equal in terms of distributed biomass. There are ocean dead zones today, and there are places with more abundant plankton life (subpolar gyres). From what I can find, information on plankton abundance during the Permian/Triassic is contradictory. There's a theory that complex ocean currents created by our current continental layout is good for productivity, and that panthalassa with its' giant subtropical gyres would be more of a desert than our modern oceans. The Permian also has the paleo-tethys sea which, if it's shallow and warm like the later tethys sea, would be extremely conducive to primary production. But, importantly, there's a theory that blue whales grew to their size because of the need to migrate huge distances between summer and winter feeding zones. Filter feeders in a world with no polar gyres, or filter feeders in the tethys sea, would have no need seasonal migration.
@@lucasb9285 well yes, but being a macropredator has never been very efficient at any point, that’s why you only see them pop up in ecosystems that are productive enough to support their existence

Looking beyond the whole question of whether whales or icthyosaurs were bigger - I think there's another question that's a lot more interesting. Baleen whales only developed the gigantism we see today quite recently due to a confluence of specific factors, and while there is the occassional extremely large animal at certain points (megalodon, perucetus etc), the only time we see gigantism on the same scale as we do today appears to be these early triassic icthyosaurs. But what enabled that? Its clearly very unusual to have so many large animals.
@@TDMHeyzeus You are completely misusing gigantism. It refers to individuals within a species of a size well beyond the average. You are using it to refer to species of very large size, and that is incorrect.

@@Dman9fp Ants are undeniably the first (as far as we know) to develop agriculture. Millions of years before hominids walked, ants were cultivating fungi
not really, when you realize that at any given time there’s only 1 or 2 (or no) lineages that are even in a position to get that big, and marine mammals are the most advanced and on average the largest of all marine animals. if it was at all common for animals to approach blue whale sizes we’d be finding them much more often.
Considering how long Icthyosaurs were around, compared to cetaceans, the possibility that they evolved to be larger than the Blue Whale makes perfect sense.
Ichthyosaurs, overall, are really underrated and unfairly put in the shadow of the other marine reptiles. They were so much more than just reptilian dolphins or tuna.
I feel like I was meant to see this today! Dr. Dean Lomax is my fave palaeontologist, I love icthyosaurs, and Blue Anchor is right by where my older family live. I spent a lot of my childhood picking up ammonites there with my grandparents, and also along the coast at Kilve and Watchet.
I find it really intriguing, that an active macropredator is also the biggest creature in the ecosystem... If true, I think we don't have an example of such foodchain. Is it the unimaginable abundance of prey or a yet unknown even larger foodsource animal, I wonder.
I've been an icthyosaur nut since I received a book about dinosaurs when I was five, 53 years ago. It's so exciting that they are getting their time in the spotlight and there's so much to read available. I often create ichthyosaur art and I have a really cool fossil plate. If time travel was possible, I'd go back in time to see them.
Incredible, Ben!! Is there any evidence whatsoever that Any ichthyosaur species we're social, or is the current view there were all loners? These wee beasties are also my favorite.
What a wonderful video! Your knowledge, networking with leading researchers, and obvious passion to learn more about these animals are clear and a pleasure to see. How exciting if a complete specimen is eventually found, perhaps weathering out of cliffs.
Something I always remember is that fossilization is rare… very rare. So we get standard sized skeletal remains. Issue is we treat the standard skeletal remains and act as if it was the biggest So sure we could have the largest ever to exist, but it’s more likely there existed a bigger version
The problem with that idea is that deep sea creatures have disproportionately large eyes because there's not much light down there. Look at the eyes deep sea sharks vs regular sharks.
Hey man great video! I noticed that you get a bit awkward with eye contact when interviewing people, me too. Just stare at their nose and you'll find (hopefully) that you don't need to veer your eyes to the ground everytime the other person glances back at you. Hope this tip helps!
Fascinating video Ben. I was particularly interested to hear how they reclassified the Aust fossil. The groove seems like such a small detail to have picked up on, and I can't help but wonder what made experts even consider looking at it through that lens. Do all paleontologists know of ALL unclassified bones, was it luck, or was someone looking at it with that specific idea in mind? As an aside, an 80 foot icthiosaur is longer than my entire house! It would have been awe inspiring to witness!
I wonder if any massive fosils may be preserved and survive in the depths of oceans? I think of how whale falls can be found in abyssal zones. But there's speculation earlier bones were less lipid rich so they wouldn't survive. Some organisms eat bones of modern whale falls. Just fun to think there's even larger fosils out there just unfound because they're in the depths
Yeah, that's possible. Oceanic plates only have a max lifespan of about 150 - 200 million years or so, but that's more than long enough to cover the Mesozoic.
Dean is awesome man! I’m sure you have very much enjoyed any opportunities to speak to him phone or in person as you’ve made it known how you admire his work and circumstances as his story is amazing really😅👍😉
I wonder why it seems to be the surrangulars that seem to be so preferentially preserved? Perhaps they were mineralized in such a way as to make fossilization more likely?
Why do tetrapods keep returning to the ocean? Also, at first I thought it was _Perucetus_ in the thumbnail, and I was confused because the size estimates were lowered months ago.
The answer is probably that there are cases where non-fish body plans present some advantage and it’s easier for them to evolve on than then evolve fins than for fish to evolve into things like reptiles or mammals in the ocean
Is there any evidence of sexual dymorphism among Ichthyosaurs? What did these giants sea reptiles eat? Did they exclusively eat fish (like Dolphins), or were there species specialising in hunting giant squid (like the Sperm Whale), or even filter feeders (like the Blue Whale)? What other species were commonplace in Triassic seas?
I’m a molecular evolutionary biologist and I can’t imagine feeling satisfied by 1000 samples in 16 years. Not sure I could handle the level of speculation you’d have to publish
I recently went camping out in Drumheller (which is in Alberta not B.C.) and visited the Royal Tyrell Museum. It had been about 10 years since my last visit, so it was wonderful to see what was new. The giant ichthyosaur really can't be appreciated for its size unless you're there, it is SO BIG. The Black Beauty skeleton was also on display, it was really striking to see! Definitely recommend going to visit if you get the chance! (Bring lots of water though, that museum is dry af and they do not have many fountains...)
It makes sense that reptiles were probably the largest ever life forms, considering that the land forms of reptiles were far bigger than equivalent niche mammals.
I miss Lyme. I wonder what Mary Anning would say about our new discoveries in Ichthyosaur. Fantastic to know something that size isn't just limited to the Blue Whale and Titanosaurs.
3:43 can i ask what is the depression around the mouth bones? was that the original impression of its entire body, or is that just where theyve cut away the rock to make the bones clearer? cos otherwise i was thinking is head looks a lot fatter than the pictures lol
I believe personally that she would be fascinated by this. The phrase "that we know of" is something she always throws out there, because it's science is always evolving and something new could always pop up.
The Royal Tyrell Museum is amazing. I highly recommend anyone traveling through western Canada to visit it. They just updated their early life section this spring.
We find fewer and fewer fossils as we go back in time, so I'd wager we have better chances of finding the largest Cenzoic whale that ever lived than finding the largest Triassic icthyosaur.
I'm highly skeptical at the idea of a raptorial predator as large or larger than a blue whale especially in weight and without the feeding adaptations of balaenopterids. Too much conjecture here.
I fully agree, it's bizarre seeing nobody pointing out that this is all speculation, the sample they have is far too incomplete to make any realistic estimations on their size
Guesstimates from such fragmentary remains are pretty useless. Palaeontologists tend to overestimate extinct animals sizes, which are then corrected and downsized when more fossil material is found. There are many examples of this, even from Cenozoic animals, which have much more closely related living relatives than ichthyosaurs.
mimics are decided by the human benchmark of what we knew of first, it doesnt matter if icthyosaurs existed way before dolphins, we knew of dolphins before the, therefore they mimicked icthyosaurs
The odds that we exist contemporaneously with “the largest animal ever” are very nearly de minimis, particularly because ~99% of all species that ever lived, as most who frequent this channel know, are extinct.
I would actually be a bit sad that the blue whale, or any currently living species is not the biggest animal known because I feel some what of a frustration about the fact we have so few big animals : all the mega faunas of the past are dead, even the elephant wouldn't have been a giant in most times during and after the mezozoic it seems and yet it's the bigest land animal we have! So having the blue whale, the biggest ever feels like a consoletion prize like, yeah we don't have alot of giants but at least you got the biggest ever. So if it is surpassed, and espescially with such a small margin, it would make me a bit sad. At least if it had been surpassed by a trully titanic being, a real behemoth, or leviathan may be more suited, that is 20 meters longer and 50 tones heavier I could forget my frustration and would juste be in awe at the thought of such a beast. But no, it might just be surpassed by something about the same size. But I do not mean to disrespect ichtyosaurs, they are really cool, and if some of them were actually that big then yes, I would still be happy that something as big ever existed, even if I'm a somewhat disapointed.
@@ericcornouiller7035 I always kind of figured that it was an inevitability that the bluewhale would be surpassed eventually. especially when you think of how hard it is for marine animals to fossilize. I like to think about the last pockets of mega fauna, and how much longer they lived for, and what stories inevitably came about from a human seeing it. like.. the human/s who saw the last short faced bear, mammoth, or giant ground sloth; hundreds of years after they were supposed to be gone. that definitely happened at minimum once for the megafauna.
15:55 and so is true for the blue whale. It's unlikely that humans discovered the biggest blue whale to ever live. It's important to keep that in mind.
We can measure the average length of blue whales from thousands of individuals, as well as the few exceptionsally large ones, the 0,1 percentile. Yet we only have remains from s handful of individuals of the few species we know,. The most likely chance is that those remains are from close to average individuals, while those top 0,1% that we have seen in blue whales haven't been found.
Ofc, there could have been even larger blue whale individuals that we haven't seen, mostly in the past. But thebig sample size we have make it very difficult that any specimen would have been extraordinarily larger than the ones we have already seen.

Same with humans being the first to make civilization.
@@YmusAnon Depending on your definitions of civilizations-- ants may have been the first
@@Dman9fp I wouldn't call an ant colony a "civilisation". Eusociality is arguably far more advanced.
@@Dman9fp Ants are undeniably the first (as far as we know) to develop agriculture. Millions of years before hominids walked, ants were cultivating fungi
not really, when you realize that at any given time there’s only 1 or 2 (or no) lineages that are even in a position to get that big, and marine mammals are the most advanced and on average the largest of all marine animals. if it was at all common for animals to approach blue whale sizes we’d be finding them much more often.
I get the impression that the Ancient Oceans could be hazardous to navigate....maybe any time-displaced humans should stay off the oceans....
Unless the time displaced humans have a submarine

Considering how long Icthyosaurs were around, compared to cetaceans, the possibility that they evolved to be larger than the Blue Whale makes perfect sense.
But growing to blue whale size is not something granted.
@@francissemyon7971 Of course not, it all depends on if they find something bigger but for now it's fun to speculate.
blue whales only largest in terms of weight anyway, not length or height
Mayhaps they dined on blue whales even, what what?
@@sirensynapse5603 no
Ichthyosaurs, overall, are really underrated and unfairly put in the shadow of the other marine reptiles. They were so much more than just reptilian dolphins or tuna.
As someone who lives in the shadow of Mount Shasta, I never get tired of learning about the Shastasaurids. They're so fascinating.

I feel like I was meant to see this today! Dr. Dean Lomax is my fave palaeontologist, I love icthyosaurs, and Blue Anchor is right by where my older family live. I spent a lot of my childhood picking up ammonites there with my grandparents, and also along the coast at Kilve and Watchet.
Oh my god now I hope that the VR Ocean Rift will include this newly discovered itchyosaur being known as Itchyotitan.
Big up Dr. Dean Lomax! Love his book in the background making an appearance, too.
I find it really intriguing, that an active macropredator is also the biggest creature in the ecosystem... If true, I think we don't have an example of such foodchain. Is it the unimaginable abundance of prey or a yet unknown even larger foodsource animal, I wonder.
It's probably lived similar to sperm whales. Giant cephalopods already existed at the time.
I've been an icthyosaur nut since I received a book about dinosaurs when I was five, 53 years ago. It's so exciting that they are getting their time in the spotlight and there's so much to read available. I often create ichthyosaur art and I have a really cool fossil plate. If time travel was possible, I'd go back in time to see them.
Orcas: Let's mug it!
😂
No seriously orcas are no joke they can literally take on almost any other animal since they are pack hunters
One of the most in depth videos I’ve seen on this subject
Incredible, Ben!! Is there any evidence whatsoever that Any ichthyosaur species we're social, or is the current view there were all loners? These wee beasties are also my favorite.
What a wonderful video! Your knowledge, networking with leading researchers, and obvious passion to learn more about these animals are clear and a pleasure to see. How exciting if a complete specimen is eventually found, perhaps weathering out of cliffs.
Oh, this video will be lovely to watch for lunch break at work tomorrow. Nice one, Ben and team!
XD real
Something I always remember is that fossilization is rare… very rare. So we get standard sized skeletal remains. Issue is we treat the standard skeletal remains and act as if it was the biggest
So sure we could have the largest ever to exist, but it’s more likely there existed a bigger version
No it’s not more likely, the larger an animal is the more likely that some of its remains of it will survive to the modern day to be found by us
It would be a curiosity to scale the size of the eye on one of these chunkies to check if it would be bigger "than" the record set by a colossal squid
You can't just write "then" where the word doesn't fit. Do better next time.
Writing through an ortographic corruptor is not easy.
The problem with that idea is that deep sea creatures have disproportionately large eyes because there's not much light down there.
Look at the eyes deep sea sharks vs regular sharks.
I love how the man you interviewed said ''chonks''
Yay, the ichthyosaur video you teased a few months ago!
You are the Best explaining paleontologist that there is period. Benji
Dr D! Hes from Donni my home town! Legend in South Yorkshire Circles! Great Vid BTW!
Hey man great video! I noticed that you get a bit awkward with eye contact when interviewing people, me too. Just stare at their nose and you'll find (hopefully) that you don't need to veer your eyes to the ground everytime the other person glances back at you. Hope this tip helps!
Fascinating video Ben. I was particularly interested to hear how they reclassified the Aust fossil. The groove seems like such a small detail to have picked up on, and I can't help but wonder what made experts even consider looking at it through that lens. Do all paleontologists know of ALL unclassified bones, was it luck, or was someone looking at it with that specific idea in mind?
As an aside, an 80 foot icthiosaur is longer than my entire house! It would have been awe inspiring to witness!
2:47, by God look at the size of that thing. Missed you guys, good to be back, I hqve lots to catch up on Benny!🤝
Amazing video bro. Thank you
I think it's really cool that they included the finder and his daughter as named authors of their paper, wish that was done more often.
I wonder if any massive fosils may be preserved and survive in the depths of oceans? I think of how whale falls can be found in abyssal zones. But there's speculation earlier bones were less lipid rich so they wouldn't survive. Some organisms eat bones of modern whale falls. Just fun to think there's even larger fosils out there just unfound because they're in the depths
Yeah, that's possible. Oceanic plates only have a max lifespan of about 150 - 200 million years or so, but that's more than long enough to cover the Mesozoic.
Ben is absolutely incredible at presenting this channel and love the scientific research which goes into making these videos!
Dean Lomax himself could be a gigantic dinosaur
more of Dr. Dean Lomax please. He's great!
If this is true, I’m happy. I LOVE ICHTHYOSAURS😤😄
Dean is awesome man! I’m sure you have very much enjoyed any opportunities to speak to him phone or in person as you’ve made it known how you admire his work and circumstances as his story is amazing really😅👍😉
I wonder why it seems to be the surrangulars that seem to be so preferentially preserved? Perhaps they were mineralized in such a way as to make fossilization more likely?
your channel has come along way man keep it up. i remember the edits of the earlier videos. 😂😂
Why do tetrapods keep returning to the ocean?
Also, at first I thought it was _Perucetus_ in the thumbnail, and I was confused because the size estimates were lowered months ago.
I would assume it's because there is/was an unfilled niche in the oceanic food chain.
same reason why insects keep on doing it, free real estate
Because they are confident that they will impress during their high school reunion
It's fun, it's easy, it's free. Just like pouring river water in your shoe.
The answer is probably that there are cases where non-fish body plans present some advantage and it’s easier for them to evolve on than then evolve fins than for fish to evolve into things like reptiles or mammals in the ocean
Top notch, Ben.

we are so blessed to live in an era where the gentle giant blue whale lives at 200 tonnes, the biggest animal to ever live on earth.
excellent presentation Ben.
Is there any evidence of sexual dymorphism among Ichthyosaurs?
What did these giants sea reptiles eat? Did they exclusively eat fish (like Dolphins), or were there species specialising in hunting giant squid (like the Sperm Whale), or even filter feeders (like the Blue Whale)?
What other species were commonplace in Triassic seas?
I’m a molecular evolutionary biologist and I can’t imagine feeling satisfied by 1000 samples in 16 years. Not sure I could handle the level of speculation you’d have to publish
I wonder how fast where small ones..with extreme hydrodynamic body and optimal tail design
It's really good how he included the discovers of the fossil in the paper
Tables turn, tables turn. 😂😂😂😂😂😂
Y’all are the best.
I recently went camping out in Drumheller (which is in Alberta not B.C.) and visited the Royal Tyrell Museum. It had been about 10 years since my last visit, so it was wonderful to see what was new. The giant ichthyosaur really can't be appreciated for its size unless you're there, it is SO BIG. The Black Beauty skeleton was also on display, it was really striking to see! Definitely recommend going to visit if you get the chance! (Bring lots of water though, that museum is dry af and they do not have many fountains...)
Sad to hear about yet another paleontological casualty of WWII.
Thanks Ben.
I think you need to do video on the difference of teeth set in grooves as opposed to sockets. This is hard to understand....
It makes sense that reptiles were probably the largest ever life forms, considering that the land forms of reptiles were far bigger than equivalent niche mammals.
As a time traveller, all I can say is 'we're gonna need a bigger boat'.
Amazing! I love this subject! There had to be some Colossal Squid hunting Ichthyosaurs! I wonder how long they could dive for?
I miss Lyme. I wonder what Mary Anning would say about our new discoveries in Ichthyosaur. Fantastic to know something that size isn't just limited to the Blue Whale and Titanosaurs.
3:43 can i ask what is the depression around the mouth bones? was that the original impression of its entire body, or is that just where theyve cut away the rock to make the bones clearer? cos otherwise i was thinking is head looks a lot fatter than the pictures lol
Can almost hear Lindsay Nikole in the background being pissed
I believe personally that she would be fascinated by this.
The phrase "that we know of" is something she always throws out there, because it's science is always evolving and something new could always pop up.

The Royal Tyrell Museum is amazing. I highly recommend anyone traveling through western Canada to visit it. They just updated their early life section this spring.
Largest ichthyosaurs may not have even fossilized
Largest blue whale probably hasn't either.
We find fewer and fewer fossils as we go back in time, so I'd wager we have better chances of finding the largest Cenzoic whale that ever lived than finding the largest Triassic icthyosaur.
Great video! Subscribed
That’s cool
I know it's the guy's accent, but "Chonks" sounds really fitting for such a large animal's discovery 😂
I'm highly skeptical at the idea of a raptorial predator as large or larger than a blue whale especially in weight and without the feeding adaptations of balaenopterids. Too much conjecture here.

I fully agree, it's bizarre seeing nobody pointing out that this is all speculation, the sample they have is far too incomplete to make any realistic estimations on their size
Guesstimates from such fragmentary remains are pretty useless. Palaeontologists tend to overestimate extinct animals sizes, which are then corrected and downsized when more fossil material is found. There are many examples of this, even from Cenozoic animals, which have much more closely related living relatives than ichthyosaurs.

mimics are decided by the human benchmark of what we knew of first, it doesnt matter if icthyosaurs existed way before dolphins, we knew of dolphins before the, therefore they mimicked icthyosaurs

Warning, detecting multiple Leviathan class lifeforms in the region. Are you sure whatever you are doing is worth it?
*If you know you know*
The odds that we exist contemporaneously with “the largest animal ever” are very nearly de minimis, particularly because ~99% of all species that ever lived, as most who frequent this channel know, are extinct.
That’s not evolution works
Seems crazy that I used to show my science teacher 7DOS clips back in 2018 in my Secondary School. I can’t believe it’s been that long.
I would actually be a bit sad that the blue whale, or any currently living species is not the biggest animal known because I feel some what of a frustration about the fact we have so few big animals : all the mega faunas of the past are dead, even the elephant wouldn't have been a giant in most times during and after the mezozoic it seems and yet it's the bigest land animal we have! So having the blue whale, the biggest ever feels like a consoletion prize like, yeah we don't have alot of giants but at least you got the biggest ever. So if it is surpassed, and espescially with such a small margin, it would make me a bit sad. At least if it had been surpassed by a trully titanic being, a real behemoth, or leviathan may be more suited, that is 20 meters longer and 50 tones heavier I could forget my frustration and would juste be in awe at the thought of such a beast. But no, it might just be surpassed by something about the same size. But I do not mean to disrespect ichtyosaurs, they are really cool, and if some of them were actually that big then yes, I would still be happy that something as big ever existed, even if I'm a somewhat disapointed.
I don't how I feel about the fact this isn't even a shitpost but something I genuinely believe.
@@ericcornouiller7035 I always kind of figured that it was an inevitability that the bluewhale would be surpassed eventually. especially when you think of how hard it is for marine animals to fossilize.
I like to think about the last pockets of mega fauna, and how much longer they lived for, and what stories inevitably came about from a human seeing it. like.. the human/s who saw the last short faced bear, mammoth, or giant ground sloth; hundreds of years after they were supposed to be gone. that definitely happened at minimum once for the megafauna.
@@davedavidson8208 The blue whale has not _yet- been surpassed.
Like any other giant prehistoric animal this thing will most likely be downsized and the blue whale will be on top again
Ichthyosaurs are getting more and more interesting.
