Ancient seas 

Fun fact- while no baby nothosaurs have ever been found, studies of the bones of Nothosaurus suggest that they may have been flexible with whether they laid eggs or gave live birth, similarly to some modern lizards. A study on the bones of twenty-four Nothosaurus showed that seven of around twenty-four showed signs of a live-birth strategy, with larger birth size, later sexual maturity, and older overall age than other Nothosaurus! also shonisaurus is a sea blimp fite me

Amazing stuff right here. Incredibly realistic. If BBC ever redoes WWD you should be at rhe helm of the technical part and dinosaur rendering.

Loved the build up from the coastal animals to the fully marine ones. Can't wait for the whole video!

Nothosaurus is my absolute favorite marine reptile, so seeing it be a major feature in this preview is quite the Christmas treat.

Nothosaurus is literally the coolest, this is truly like peaking into the past

I love how the Nothosaurs' behavior is somewhere between that of a seal and a crocodile, and how rounded and whale-like the Ichthyosaurs are. Can't wait till this is finished!

The giant Ictheosaur at the end was amazing. It's speculated that there was a species of Ictheosaur that may have been the largest marine reptile. Great video.

Do I really need to say how wonderfully crafted this animation is 😂. Merry Christmas my good sir! 🎄🦖

You never fail to amaze me with your animations. Truly amazing work!

It's looking amazing!

This is awesome...please keep up the great work :D

This is just the preview? Dude this is a masterpiece.

This video is one of my favorites , no one can beat you at this.

Julian this is the most magnificent work of art I have ever witnessed in my life you have my respect and love for all of eternity

Shonisaurus had guaranteed a good great end. Gorgeous work as ever

Awesome! It's great that now you are giving them reflections in the water. :) Makes them even more realistic.

So wonderful. I've got relaxing feel like I've walking in the prehistoric world.

Prehistoric oceans always interested me deeply, and your work here is truly beautiful

Amazingly realistic! With the enjoyment of watching, one more thing is left for the viewer, to imagine tiny human in the water with these beasts.

Thanks for the Christmas present! I like the nothosaurus eyes. They look less "googly eyed" than the plesiosaurus. :D

What an amazing present to all of us! Thank you so much. Brilliant as always. Looking forward to the whole show.

Hands down the best animator on RU-vid I’m trying to make similar dinosaur themed videos but am humbled every time I see Julian’s work. Mike

The CG on this looks absolutely gorgeous. :D

You are seriously one of the only reasons i still regularly check RU-vid. Amazing videos for real

Those Nothosaurs be looking awesome!

Man, just check the detail on the the tiny and spiky scales on the sleeping nothosaurus... impressed at all of the species variety going on in a single episode too. Stellar stuff, as always ^_^

I damn near screamed with how awesome this is. I am SO excited to see the finished product. Absolutely fantastic work.

If only there was a TV series like this... if only the BBC would hire Julian for WWD2...

At this point in time it’s as close as we can get to actually being there. 😮 My favourite window to the past.😍

Looking amazing as always! Merry Christmas!

What can be said that hasn't said already? This is amazing! I can't wait for the full...documentary? Movie? Whichever one it is, I'm excited for it

What kills me is the title says it is a preview. This is so dynamic so beautiful. Every second of this video would make any movie goer blow their mind and yet...This is a preview!

Great stuff... Can't wait to see something with a longer time.

Dinosaurs look awesome. You're the best. 🌟

AMAZING

this looks so, so good. amazing work can't stop watching it over and over again 😍

Awesome work, dude! I can't wait to see the full thing!!

Thank you for the alert of this new video, Julian! Love all the new guys! Can't wait for the completed version!

This was a *lot* better then I expected. This is real professional quality work. I hope we're going to see more of this quality!

Outstanding work Julian! Merry Christmas!

Sweet, we get to spend more time with the Nothosaurus! And with Shastasaurus and some little pliosaurs! Can’t wait! Merry Christmas, Mr. Mortimer!

Spectacular! Absolutely enchanting!

That was incredible! I loved the touch of container cargo ship on the horizon at 1:35.

Your animations are EPICALLY AWESOME !!!

Absolutely amazing! Another wonderful clip. Thank you!

You're videos are a Therapy for my unquenchable thirst for Jurassic Word franchise Absolutely daily aquarium of dions on the screen

I love you how your designs don't have to be accurate at all to be amazing

This was such an amazing looking video. Just transported me back in time. The music was perfect and utterly majestic.

Looks amazing. For me, doing this is merely a dream.

The comping on this one is amazing! Really nice work, you def stepped it up on this time.

Magnificent!!!! Merry Christmas 🎄🎁

How...you need to be doing this professionally! You're incredible!

I wish movie or TV producers would hire you make stories about the vids you sir are making. Very, very wonderful!

This is amazing

Beautiful quality work- as always. Can't wait for the full finished product.

I love the little underwater-flying pliosaurs. Like Cretaceous penguins.

OH MY GOD! this is ridiculously amazing! I can’t believe how incredible ur work is! It always seems like it couldnt POSSIBLY b any better, but then u keep coming out with new ones that are even BETTER! The only bit of critique I could possibly give, which by the way, is NOT saying anything is bad in ANY way, is that I feel like some of the aquatic life has too much texture on their skin. It looks absolutely breathtaking, and so incredibly real, but for animals that are meant to be very fast moving, like pliosaurs, plesiosaurs, ichthyosaurs, sharks, dunkleosteus, and other fish, they have to have very smooth streamlined skin. Any texture at all greatly reduces their hydrodynamics, which makes them either slower, or have to expend much more energy to move faster. Again, I do NOT think it looks bad at ALL, I think it looks AMAZING, I believe it’s just not as biologically accurate for them to have the skin textures/folds/flaps. I think it works great on the things that don’t need that kind of speed, like the nothosaurs, and even the individuals of any type of animal, including the fast streamlined types, that are the huge very old ones, that have been alive so long that they just have wear and tear. Please don’t ever take anything I say as saying there’s anything wrong with ur work, and that it doesn’t look good, but if I could help u in ANY way, I would be SO happy, and if I think there’s any possible way ur work could be even BETTER, I want to help make it so! I truly believe as soon as the right people see ur work, they’ll look into either bringing u on board with their company/station/business, or at LEAST want to commission u for doing documentary work, and I can’t wait to see ur work on something like that! Again, if ANY of u people out there happen to know anyone, or know anyone who KNOWS anyone, in the TV business, or internet, or any visual media,pleasepleasePLEASE forward, or let them know about Julian’s work, here! Bring it to their attention, and have them take a look! It’s for our sake just as much as his! Imagine getting to see whole documentaries with this animation! Just the idea of all the possibilities makes me very excited, and want to watch them, so badly! U guys can make all the difference for someone who works so hard on stuff for us to enjoy, so everyone PLEASE do whatever u possibly can to make it happen! I know there MUST b at LEAST one of u out there, and probably more, are in a position to help with that, so PLEASE take the extra time to help out EVERYONE, especially someone who really deserves it, and almost makes us time travel back to see these amazing animals in real life!!!!

The ichthyosaur babies coming to they mother

Wow absolutely amazing every time I watch your videos I feel like I'm back in time the dinosaurs just crazy thank you so much for posting these

This man DESERVES A Oscar right now

Thank you for continuing to share your beautiful creations. It's not just the wonderfully detailed models, or the gorgeous effect. Your attention to presentation is just breathtaking. Truly immersive and wonderfully complimented by the soundtrack.

AMAZING!

This is awesome the animation is off the chain love it!!

Just needs a few ammonites and you are golden. Absolutely gorgeous, gives me goosebumps. What I wouldn’t give for universe view only admin powers to see ancient seas past.

Incredible as always. This is seriously insane. These must take SO long.

This is the most underrated video I have ever seen

Bravo Julian! This looks almost most like a nature documentary. All that missing is the narrator.

Never failing to amaze us with your animations, Julian, you always deliver

The Shonisaurus is majestic! I'm looking forward to the finished version!

Bravo, truly amazing work as always. An absolute pleasure to watch these short films. 🙌🏽 have a happy new year! 😊

Your work is so great! My 4 year old is DINOCRAZY and has revived my interest, and we both love your videos! Thanks for making such awesome stuff!!

Such amazing work! What an awesome Christmas present for your fans! Merry Christmas!

WOW

Wow! As you know, I never stop watching these videos cus they’r very well made, and I like dinosaurs:) And all reptiles.

THE PREVIEW IS 3 MINUTES. THIS IS TOO *AWESOME* Take care, Julian! ;D

Your work is so amazing! I got so happy when I got this notification! Please keep up the great work! 😩🙏🏽💪🏾

Very nice! Amazing work.

I like the way this animation portrays all of these animals as animals living in an ecosystem rather than as intentionally scary monsters like many animations about prehistoric creatures seem to be.

Amazing, interesting video. And the super Tanker on the horizon at 1:30 is actually extra-fun ;)

This is amazing! I'd love to see a full movie with animations like this. With or without a narrator. Well done, great work!

Wow, what a wonderful Christmas present to share with us ! Thank you again for these great animations, and kudos to your collaborators as well. (Mika's music is always perfect for your videos.)

Honestly, (and I don’t want to sound like a hater) the only problem with these videos is the size, sometimes the animals are over or undersized, but other then that its truly magnificent.

The visual effects in your videos look so realistic. I wish I knew how to do that. Then I could make my own videos

Absolutely stunning animation!

The whole video looks beautiful, the creatures that are shown are interesting, the triassic is sadly very underrated, especially the marine life then.

another masterpiece , i really love and enjoy your work

Such majestic creatures I love prehistoric animals:))

Dude this actually looks like a movie by the sounds and graphics :O

Amazing! I Love it!!!

Amazing work! Cannot wait for the final version! (be careful, there is a boat on the horizon on one of the coastal shot...)

I can totally see Nothosaurs having a lifestyle similar to Marine iguanas, Great work btw.

Dude this is incredible. You definitely step up from the last aqua video. A wonderful gift. Merry Christmas!!!

Just love your animations ❤Absolutely brilliant !

you are too good, time to start considering to make a proper docu series of many episodes, 60 minutes each, it would be like reviving dinosaurus again .. please

Such an amazing gift to your fans. Merry Christmas, and may the next year be brighter.

I never get tired of watching your work... Incredible

1:02 😊 nothin better than a good nap after lunch! 😌

Animation is so much better in this than in the walking with dinosaurs series. Awesome job, really cool.

Man these animations are stunning Julian! Even though I am not too deeply into dinosaurs I still can't help but awe at these videos youve made! ☺

Wow, I've just watched something incredible. Love animations and the music is amazing. Subscribed already and waiting for January!
