We live in north texas, near Dallas. Which is an area where we find many mosasaur vertebra. The Dallasauras was found aling with other types of mosasaurs. We also have found shell remnants from the ancient turtles. Very cool.
The closest thing I can think of are maybe long necked water birds that paddle on the surface and sometimes dive, such as swans, geese, cormorants, etc. I know they're vastly different though...
Amazing video, but You forget the biggest. Large rather recently discovered variants of Ichtyosaur surpassed 30 m in length, maybe even dwarfing the blue whale!!
Teeth teeth teeth 😱 Worse than sharks. Just think about if they were still there.... We just couldn't swim anywhere. They're all made to eat us as candies. Thanks for sharing this
1. I just ordered a full-size Temnodontosaurus to hang in my Great Room. Amazon is delivering it to my front door. I told them to hide it behind the rocking chair so no one would steal it... 2. Shown is a smaller version of the Plesiosaurus. So far (according to 'AI Overview') their range in length has been found to be from 4.9 feet to 49 feet (how many meters is that? A bunch)... 3. I gifted a Kronosaurus to the Great Lakes that I trained to clean up the invasive species (minus some humans, of course)...
The loch ness monster could have been one of the little critters because the photos never show it next to a person for size reference. They would also explain why finding them was so difficult.
Liopleurodon was famously depicted as 20m in length in Walking with Dinosaurs, but it was based on controversial and little believed estimates from fragmentary fossils.
It's wild to see how even though they ALL had 4 limbs/fins, their tails were still vertical. It's like they're right in the middle of the evolutionary process: They still slither from side to side for locomotion as their ancestors did, but they're already in the process of also evolving limbs and legs to go out into the world. (The ones that did venture out onto dry land and then came BACK to the water is why whales have horizontal tails instead of vertical ones).
All of these animals are descended from terrestrial ancestors. The difference in tail motion is because mammalian spines flex differently from that of most reptiles. When a mammal walks its spine will flex up and down to accommodate the movement of its limbs. Likewise, when a lizard or crocodilian walks their spine moves side to side. When the ancestors of cetaceans and marine reptiles first began living in the water they retained these motions in their swimming.
I've always thought that the smaller named species were just babies of the larger sized similar species they find, and not a different species altogether. Like the Malawania is probably just a young Shonisaurus, who is juvie of the Shastasaurus. Could be possible.
This needs to be updated since the largest sea creature ever discovered, which now beats the Blue Whale in terms of length & mass, is Ichthyotitan which is 25 metres (82 ft) long while the Aust specimen is 30 to 35 metres (98 to 115 ft) long.
It's cool to see them all side by side and with humans for size, and the rendering is good but the actual reconstructions are atrocious. Necks, fingers and big scales on what would be smooth, whale-like sea creatures, it looks really pre-1980s in reconstruction style.
Cool, but periods of existence are missing. Some of these animals were predators and others were prey. And some lived when others disappeared or where not here yet.
@@blakestillwell4295 That's true, we don't know the shape of Ichtyotitan. But it's length has been estimated to be 25-26 meters in two different papers, comparing the matherial to other Shastasauridae; for now, that's the accepted size estimation and our current understanding of this animal. I truly see your point, but I think that a size comparision of marine reptiles should have the largest named marine reptile on it. This size comparision also has on it other fragmentary species (Temnodontosaurus being 12 meters) and outdated/hightly improbable sizes (Mosasaurus being 18 meters).
@@MarcoAntonio-ks6sk and thats what I actually came to the comments for, was the outdated mosasaur lol. Good to have a conversation with someone who is not only knowledgable on the subject, but also not looking to argue. Too much of that going on these days lol.
@@zyxw2000 well there is literally a fish found that survived 66 million years lol. And I didnt say it is a single nor that is materialistic. Might be even supernatural. Plus its True that plesiosaur is bigger than fish but still. Beside that if its True than it might be supernatural
Ancient marine character creation options :
• no neck
• 70% bodylenght neck
also stubby tail vs 50% bodylength tail
Hit the jackpot this time, many of these marine reptiles I had no idea existed!
Well the are prehistoric
its also possible they never looked like this but who knows? but def interesting alright!!
You are all losers
Kronosaurus is the most brutal, no stolen length valour with a long tail or neck, just all smashing machine.

I think I know exactly where that is! I’ve been wanting to go! But I wasn’t sure id actually find anything. Do you often?
Those people are quite nervous standing next to these creatures
Bad UA-cam joke
I thought it was a little funny 😅
I mean, I'd be too. One bite and I'm done.
Fool they are extinct.
Indicate carnivores having human parts in mouth.
Omg babe get the popcorn out “ Ancient Marine Reptiles Size Comparison 3D” is on.
Don’t forget icthyotitan! It’s the biggest known marine reptile. It was discovered recently
And it’s already an impressive creature.
May we just appreciate how good your 3D actually is!
Interesting, how the long-neck-type of water-dweller has no current day counterpart, while the fish-likes are "replaced" by dolphins and whales.
Maybe if giraffes would ever evolve to live underwater, we would have long neck aquatic mammals.

Have you ever seen Anhingas and cormorants?
@@monamibeyblade_chinois Those are not living in the water, but around and above.
@@thylacine1154 Yeah, the comment around yours said the same.
The best scale representation that I have seen. 👍👍👍
Above all, it is very accurate and based on the most modern estimates.
Thanks for the folks standing there to give scale: So often these "size of...." videos do not give the viewer any comparisons for reference.
Wow, thank you! That was amazing. I love the comparison in size to humans.
Glad you liked it!
@1:40 Wow, did David Attenborough really have a marine reptile named after him? What a great honor!
A MAGICAL LIOPLEURODON!!
A strangely very small one at that.
They are not magical, otherwise they will still be alive.
...Charlie!
A magical Liopleurodon of hope and wonder! We're on a bridge Charlie!
Only thing that could improve the video is showing the time when these animals roamed the seas.
Bikini clad women would make it better!
Incrível como as roupas daquela época já eram iguais as de agora. Kkkkk
Amazing video, but You forget the biggest. Large rather recently discovered variants of Ichtyosaur surpassed 30 m in length, maybe even dwarfing the blue whale!!
Not quite.
dwarfing is a strong word. estimates put it around 26m.
@@martinkocsis5035 that’s one of the lowest estimates.
@@lukaskoch2508 lowest estimate to my knowledge is 22m and the highest (informal!) estimate is 35m.
Thank you thank you so much for not saying “marine dinosaurs”. Whenever I read that I see red.
Notice how all the humans are nervously looking at their feet.
They are all extinct.
You would, too, if you were standing on water!
My favorite shastasaurus good video.
Mosasaurus should have had a bigger part. In Jurassic World.
It deserves a spin-off. In the proper hands could be an amazing sea-horror film.
They made it Godzilla size. That was stupid
The writing and development of a good plot and characters should have had a bigger part in the production
Well, doesn't help much when it's a creature that's only restricted to the water.
Shoulda been bigger in Ice Age 3 too
😮😮😮🦖🐋 awesome marine reptiles
Life on planet Earth is someone else's lab experiment they got bored with and left running.
I had no idea Plesiosaurs were so small...
I love the little guys
Very cool. This did a great job of reminding me why I hate the ocean 😂
The music's amazing! Anyone know where it comes from?
Chulainn - Northern Mist
Considering how big some of the larger members of the family get, it's super easy to forget the OG plesiosaurus was tiny
Excellent vid. Really liking the detail in the individual NPC characters.
Very fun video, nice 3D modelling!
Plz do universe size comparison its the best
Teeth teeth teeth 😱
Worse than sharks.
Just think about if they were still there.... We just couldn't swim anywhere.
They're all made to eat us as candies.
Thanks for sharing this
This is nicely done. Next time, please also include time period in which they lived.
That’s easy. 6,000 years ago.

I'd like to see some of these in a horror dinosaur film.
What !!! A Mosasaurus isn't "280 Zillion feet" long like in the movies !!! 🤔 😆🤣😂
One of these must inspire the lochness monster
The music is amazing! 🤘
Played by a band of large reptiles (they're just pretending to be extinct).
Great video, even though Shonisaur has that derp look.
I always thought of Nessie being so much larger than a plesiosaur was lol .
The 'payninarsus' evolved into the present day...'mother in law'.
Awesome. 👍
Great video

Liopleurodon wasn't that small, infact they were just a little less big than the Mosasaurus
Liopleurodon was famously depicted as 20m in length in Walking with Dinosaurs, but it was based on controversial and little believed estimates from fragmentary fossils.
Dude, all these animals are awesome, but how cool is it that we are alive to see the earth's largest ever creature, the God damn Blue Whale!
It's a magical Liopleurodon, Charlie!

not possible. the archaeologists know that there are morphological differences between a young and an adult specimen.
I'd like to see their masses, too...
This would be even better if it included the times in which these reptiles lived, i.e. 120 MYA, etc.
0:03 First Mosasaur is so cute.
I think they all are in their own cute/derpy/interestingly unique way 😊
Quite fascinating as to how they’re still referred to as ‘reptiles’.
美中不足的是每个生物没有标注对应的地质年代

Fishing was so fun back in the days
Pure dead brilliant.

I caught a Mixosaurus down the bayou fore. Fried it up. Not bad.
Man if these creatures still existed i would not dare to step on toe near the ocean
Imagine whatever humans evolve into 2 million years later saying that about Holocene oceans 😂
It would be interesting to know how long ago each of these animals lived…..listed under the name.
I know the guy that found one of those basal mosasaurs in Dallas.
No list like this can be complete without Dunkleosteus!!
Dinosaurs disappeared when they kept seeing the same NPCs over and over and logged off thinking it was an Oblivion server.
Смотрю видео, люди становятся всё меньше и меньше😂
Glad that they are history and not roaming the seas.
Intéressant
*Shashtasaurus and Shonisaurus should be renamed to...blimpisaurus and beach-ballsaurus, respectively.*
Aquatic Reptiles.........😐 Reptiles under Water 😵.......can't find those at an Aquarium Center.
Elasmossauro é incrível
It's crazy how the dinosaurs actually outclassed sea reptiles in size
I am gunna need a bigger aquarium!!
Cheers. 😎🥃
Anyone else notice that nautical theme playing in the background?
Where is Aust Colossus and Hector's Ichthyosaur?
Where are you getting all these animal assets from?
It would be nice if you put their epochs with their names as well.
It’s a Liopleurodon, Charlie!
It's easy to assume they're much bigger without a size comparison.
Mixosaurus? Finally I found a new DJ name.
I found part of a plesiosaurus skeleton, its much biger than 3 meters... are you sure ?
I’m amazed that life on Earth once said “Let’s have Fat Dolphins and see how that turns out.”
The oceans must have been teeming with food with creatures this size. Must have been beautiful but scary at the same time.
As a man of culture of course i clicked on a video titled "ancient marine reptiles size comparison."
Well, not included is the approximate weight of these creatures. I know some one has guesstimates....
That’s one big turtle.
I didn't realise the Loch Ness Monster came in so many different sizes.
Why do so many of them have short tails? Is it now known for sure they were so short? They look so unusual compared to (probably) older concepts
Interesting, most of them lived from fish according the their jaw size and build. Very few predators we would need to "fear".
Cool, but periods of existence are missing.
Some of these animals were predators and others were prey.
And some lived when others disappeared or where not here yet.
What about Ichtyotitan? It was 25 meters long
*estimated to be 25 meters long, not confirmed by any means

Also Megladon were approximately of same size as tylosaurus and mosasaurs.
