When Sea Monsters Became River Monsters

- If any of you have seen WWD Sea Monsters, you would know to never enter the oceans and seas during the age of Dinosaurs. However, in true Mesozoic fashion, not even freshwater was safe back then as every so often, one of those ancient sea monsters would figure out how to make the 'leap' to freshwater, turning themselves into River Monsters!

I still cannot belive that prehistoric waters were full of creatures a sailor would find extremely close to those in legend, its a weird coincidence

Historians: “Cameras didn’t exist then, so none of the tales could be true.”
With video evidence: “I said these are extinct, so this must be a hoax because I’m God and so what I say miraculously is automatically true.”
Public: “See? He said it, so it must be true you stupid conspiracy theorists!”
@@midgetydeath what are you on about
Not quite. Giving the incredible array of shapes and sizes of aquatic reptiles, it is rather remarkable that no fossil of true sea serpent has ever been found. I am talking about a water snake that would be at least 20 meters long, to accurately mirror the sea monster of legend. Or any other serpentine-like non-reptile creature (whale Basilosaur, regardless what some folk claim, was anything but serpentine!). This monster remains a legend.

This is a River Monster Guy moment, he'll be having a field day with this if they are still alive today

Just chilling in a deep pool with mosasaurus
@@paleoph6168He's still alive
River Monsters will come back when commercial time machines are possible. The only reason Jeremy stopped was because he caught all of the noteable monstrous freshwater fish
@@giagarexthat’s what the Illuminati wants you to believe
There are actually a few records of freshwater mosasaurs throughout their existence, from the Turonian to the Campanian. Most seem to belong to Tethysaurinae and all seem to be under 6 meters in length. It’s possible that competition with larger, more derived mosasaurs forced the Tethysaurinae to retreat into freshwater environments and retain their plesiopedal-plesiopelvic morphology far longer than their oceanic brethren
Back in the early 80's they discovered one of these in Hayden Alabama and they were still digging it up the last time I read about it and it made the world weekly news a tabloid that was in black and white print and pictures and it was owned by the National Enquirer back then by a former boss I knew that it was a real story because it made the television stations that we got by antenna and then by cable. And the Birmingham news as well.😮
A friend of mine once said "we pretend they're not monsters anymore just because we gave em a name" and honestly, yeah.
You should look up the definition of "monster".
@@JediDrPepper049 He's got a point though. Since we fear what we don't understand, naming and classifying "monstrous" looking beasts will actively colour our perception to make them appear less fantastically dangerous. Of course, someone who has gone face to face with one would quickly disagree.
@marzipancutter8144 no, he really doesn't. A monster is literally an imaginary creature.
Words have definitions.
@@JediDrPepper049 No, it isn't, like, at all? People have been calling real beasts monsters ever since the conception of the word. Imaginary beasts are a part of the definition, but it isn't an exclusive one. If some definitions limit themselves to imaginary creatures nowadays, those are neither universal nor very accurate. At best you can say monster *usually implies* imaginary, but excluding real monsters is disingenuous at best and horribly misinformed at worst.
You can't just take the first definition that comes up on Google. The word monster can and will be used on real animals, and the only reason that trend may be in decline is precisely because of what godzillacc5 said.
If you are in any way serious about the definition of things, you should recognize that linguistics are descriptive and you cannot force your homebrewn definition on people using the word correctly in everyday language. Now get outta here.
@marzipancutter8144 and dumb people say trump won
In 2020, does that make them right? Dumb asses misused words all the time. Tell you what, you got a smartphone, right? Got Google? Maybe then type in " Monster definition."" But that is just too big 🧠 for some people .
As a Florida man, I would 100% travel back in time to the period and place where Pannoniasaurus lived to wrestle it
As a Florida man, I would be trying to eat it.
Remember to cover its eyes.
As a dude from Texas I’ll bring the beer and watch
We Floridians are a unique breed.
I can only imagine how fertile and productive those environments would have been, in order to sustain multiple bloodlines of creatures so large.
It makes sense plesiosaurs would outcompete ichthyosaurs in a freshwater environment; ichthyosaurs are more specialized to swim the open seas, they’re literally built like torpedos. A world full of freshwater plesiosaurs would be terrifying, I wish I could see it.
We actually don't know that there wasn't any freshwater ichthyosaurus.
Sad Nessie noises.
The genus name of the fresh water mosasaur comes from the Roman province Pannonia, which in time became Hungary.
History repeats. Millions of years later, what's now Hungary, Black Sea and Caspian Sea was one large fresh water lake and had a fresh water species of Baleen Whale, or so I've read.
The level of ancestral, even instinctual memory that must be involved in so many legends taking the form of creatures that did once truly exist, but may have never even been seen by human eyes beyond fossils, is fascinating
Mosasaurs are impressive since they didn’t rise following a mass extinction
Very interesting that _P. inexpectatus_ might have had feet. Those would have been more useful for navigating an obstacle-ridden riverine environment than flippers. This is possibly one reason a certain lineage of lobe-finned fish evolved them in the first place!
You could say it would be quite unexpected…
An interesting note. The majority modern Marine Species that can thrive in Fresh Water just happens to be Air Breathers, so it's reasonable to say that almost all Prehistoric Marine Reptiles can make the transfer between Salt and Fresh Water
It would be cool to see a video about quinkana the giant land crocodile of Pleistocene Australia that was around with megalania. Also it’s cool learning about these freshwater species that are generally known as marine apex carnivores. Wonder if any Cenozoic monitor lizards evolved similarly? There are reports in the Congo of a large semi aquatic varanoid of some kind reminiscent of the Borneo earless monitor lizard but a lot larger. Would be a cool discovery if there is some thing like that in the Congo.
Ayo I'm calling Jeremy Wade
Fresh water mosasaurus would definitely make me shit bricks. Lol
At 2:11 - it's my good friend's artwork, his name is Tibor Pecsics (you can see his name at the right bottom corner).
Thank you! Added to description.
@@ExtinctZoo Many thanks, much appreciated! ☺
Prehistoric sea monsters
excellent video as always!
I cannot thank you enough for bringing people this content. Thanks for being awesome 🙏🏻
Thank you for the content you make. It helps me get through my troubles. My dad left to go get mental help because he was quick to anger. I just want him to come hone
If half those creatures were alive today its possible Humanity would have never learned to swim and just avoided the water all together.
Similarly could be said about the terror birds or most of the ice age megafauna. But considering how many creatures were and are being wiped out in one way or another? Humanity could probably find a way to kill or eat them.
If not? It dramatically shifts culture entirely. Sinocentric cultures would probably cast the Dragon in a far less benevolent light if there were serpentine like creatures swimming up rivers to kill early man. Much like how snakes evolved into a negative idea of dragons in the west.
Water is just extremely essential to life and civilisation it would mean many unless they adopted more martial cultures and upbringing would likely always be at the mercy of these creatures.
Then again? The Nile has hippos and alligators.
Nicht unbedingt orcas und pottwale fressen auch keine Menschen obwohl sie es könnten.
Two thoughts: 1) ichthyosaurs are evolutionarily older than plesiosaurs-I wonder if there are some Triassic freshwater ichthyosaurs or stem ichthyosaurs out there;
2) imagine reeling in a big fish only to have a dang pliosaur grab it and break your line
I hope some crazy scientific just clone a bunch of these monsters and release them into the rivers without anyone knowing
I love your channel ❤❤
It's called a Paniniosaurus because that's what you would be to it.
Even Steve Irwin wouldn't want to be near it
LIES!! He’d be one of the first to try to pet it
8:10 unless you count Nessie and other aquatic cryptids.
They be finding competition with crocodiles 😂
Cool video, but no one talks about how handsome this man's voice is
Can you make a video on megalania ?
It was a monstrous monitor lizard from Australia
megalania isnt a valid genus anymore, its been reassigned to Veranus
@des9930 It’s still valid to call varanus priscus megalania.
@@jointcerulean3350 ah my bad
just thought I'd say it since I don't know if many know about the reassignment
again my bad for not knowing that
I thank the algorithm for finding you

The one thing we have yet to find is a flightless pterosaur. They had to have existed. We have flightless birds and even a flightless bat.
If it flightless is not one…
@@lucasb9285that's like saying a penguin isn't a bird.

First time seeing this channel,subscribed!.
I LOVE your channel! Just found you guys today, more MORE!
Jeremy Wade hyped rn
This is why I believe in cryptids. After all, the kangaroo began as a cryptid.
Great video.
So the plesiosaurus in the river in Turok was historically accurate. How quaint
imagine if Nessy was actually real and thus one of these guys :D
I don't see how you debate against it, it's completely possible there were or are prehistoric creatures still living within our timeline
River mosasaurs are underrated
Awesome!!!
Plot twist they adapted and still live in lake illiamna
just so many animals we could have eaten, so tasy fr fr 🤤🤤🤤
Mosasaurs adapting to fresh water isn't that surprising, given that they're suspected to have evolved from either monitor lizards or limbed proto-snakes. Both varanids and snakes include multiple freshwater-swimming species.
Besides the Meg and the Lyvatin these guys were the scariest beasts to ever swim in water!
If the fresh waters where the least affected by KT extinction then how come none of these large freshwater marine reptiles survived but the crocodiles and alligators did?
Hm. It would be lovely- if you'd make some video about fresh water sharks of prehistory- i have to say, that information for a casual fan of prehistory on that topic is rather hard to find
i love the paleoart you use!!!
me to
Awesome
I need more videos like this in my feed
Mossasaurus lived in Hungary??? Iam from Hungary, what the hell??? Hell yeah...
The long neck would be useful when approaching prey head-on as prey probably wouldn’t realize the head was far closer than the body.
I would think a large , stocky body would make it hard to hunt , being hard to change directions. But add a long , flexible neck that can whip off in any direction would negate that disadvantage
I HAVENT WATCHED THE VIDEO YET BUT THATS THE NAME OF A SHOW
Jeremey Wade…… Fish On.
Teeth started out as armored plating on ancient fish. Armored Plating on armored fish moved towards their mouth where they became extra useful, like dual utility. This is the origin of teeth
0:51 what is this clip from? Would love to watch the full segment/episode/film
i've been searching and apparentely is from a series called "Amazing Dinoworld" (specifically S01E02 - The World of Sea Monsters)
Those brawn and white stripped fish look like precursors to dolphins. They look like fish but have that dolphin shape.
Not sure about wanting to be around back then with river swimming carnivore Komodos.
😬
So basically was just another crocodile species until they actually know what it's limbs looked like.
same reason why there are fresh water dolphins in the Amazon basin
Please can someone tell me the spino vs mosa clip is just before a minute into the vid
Ogopogo, and the Loch Ness Monster....hmm??
If anyone plays Path of Titans it’s so much fun to play as a Mosasaur and swim upstream and fight Sachicasaurus and Sarcos in the river
Can you make a entire video of archeopteryx
Seeing how many subspecies of archaeopteryx are there because I heard it was two A lithographica A seimensii
And also I was wondering did archaeopteryx practice parental care because I saw a picture of a embryo from a archeopteryx lithographica
i thought it was bigger but aight its cool anyways
Bruh a fully grown adult is smaller than an average adult whale shark!! Boy am I happy whale sharks are filter feeders
Wait, are you saying that Nessie, Champ..n every other lake doesn't have a sea monster?!😂
Hey just letting you know TH-cam unsubscribed me from your channel.
Not really sure why.
What is that spinosaurus getting mauled from?
maybe the real monsters were the friends we made along the way
Titanoboa video coming?
hi
Nessie was real, and dangerous
I like pannoniasaurus
These guys went extinct
After they found out their fate.
To be dominated by Jeremy Wade
Why don’t you get to think and make a suggestion creating another TH-cam Videos Shows that’s all about the Extinct Prehistoric Amphicyons (Bear Dogs) on the next Extinct Zoo coming up next?!⭐️⭐️⭐️⭐️⭐️👍👍👍👍👍
3:43 does anyone know the name of the painting? Like comment if u reply so i can get notification pls
as i understand, mollusks and fish are not animals
living in the kem kem environment must've been crazy

At least 2 of the largest predators the world has ever seen
sawfish that actually weren't
tiny plesiosaurs
a 7 foot coelocanth
a (possibly) 3 meter lungfish
15+ meter croc with a very round nose
giant pterosaurs
sauropods halfway between brachiosaurs and true titanosaurs
the whole works
Guess he got braces 😬 🤪
Loser weirdos: I don't swim in the ocean! There's sharks in there!!
Me: (After watching this video) It could be worse...
> Making it the largest predator in the water (You mean freshwater?)
I'm sorry, but this creature will no chance against Deinosuchus if they came across each other.
Wrong time & place.
Mabey they aren’t extinct
Yikes
I Wouldn't be surprised if there was under the Sediment like The meg if that Is True and they may have something still in the deep earth 🌎
Dude sounds like Jame Gumb
The dinosaurs were so incredibly violent and aggressive that when the ecosystems destabilized even a little, numerous species would go extinct rapidly. The reproduction and violent death rapid cycle could not survive any imbalance. Not surprising eventually they were worn down to modern animals, which require far less energy and usually developed warning systems such as colors and threatening gestures and sounds to avoid unnecessary fights. Among other such adaptations such as being able to go long periods without food.
What the fuck are you talking about??
Whats amazing is that they too more than likely had warning systems. I think they were a lot more developed than we still think, seeing as nodosaurs had counter shading.
We got Earth after the nerf. Kind of lame tbh
I dont believe in “evolution” but i find these video’s interesting
These videos are key examples of it though
@@novathehedgehog90 in what way?
@@inactivated101Showing adaption to living in a freshwater environment. Millions of years beforehand when early reptiles split into the two lineages that become dinosaurs and marine reptiles respectively. Another important one in this video is convergent evolution, animals getting the same body plan because of it's success. Ichthyosaurs aren't related to sharks or dolphins at all but look similar because it was an open ocean animal and was adapted for that life.
What if science has the plesiosaur backwards? Meaning it had a long tail and a short neck.
They have skeletons lol...
Actually, when they find fossils for the first time, they think exactly that, it was wrong reconstruction.
People didn't what plesiosaurus looked like back in the 1800s......at least not from fossils, yet they got paintings of em? Im sure its a coincidence and not at all real, just a lucky guess.
Plesiosaurus fossils were already known in 1800s and scientists had general idea how they looked like, although of course their knowledge didn't go into every detail.
@@melanimatejak6821 evidence please
@@a_fuckin_spacemarine7514 ever heard of Wikipedia? Or if you have time go to some large library and look for paleontology books dealing with sea reptiles. The central for those discoveres was 19. century England with its coastal cliffs which are regularly eroding and releasing plenty of fossilated bones.
Male play2us. 😂
Dude... are you pitching down your voice? 🤔
I would assume since they all breathe air that they all regularly swam in and out of fresh and salt water depending on food opportunities
