Found out about this fact a little while back, and immediately thought about this channel:
"Most of the world's bodies of water are less than 18,000 years old. There are only 20 ancient lakes over 1 million years old."
Lake Baikal is the most famous of these, and you've already talked about it, but the stories of each of the rest of them are just as interesting
Why are the bodies of water so young?
@@concept5631 they were formed at the end of the last Ice age.
@@Nate-yb3ce Ahh alright.
Thanks for clarifying.
@@Nate-yb3ce Now that is bull🤣 When water freezes and melts again it does not make it younger🤣
The water was there millions of years before the last is age dude🤣🤣🤣
@@concept5631 They are not... Try adding a couple zeros
"One for the Land
One for the Air and
One for the Water"
makes it sound particularly epic.
They need one for fire and it would be the Avatar The Last Airbender
@@matthewwelsh294 Dragons
you said the citation... and you'll be pleased to know there is a logo for this:
"One for the Land
One for the Air and
One for the Water" is the Mercedess Benz logo
The 3 lines that form the shape represent land, water and air... you're welcome
Sounds like the lotr intro where they talk about the ring
More like a nursery rhyme
Despite the popularity of the word Jurassic, the Cretaceous seems to be getting most of the attention cuz most of the newly discovered dinosaurs nowadays come from that period.
So it’s nice to see a video focus on the Jurassic (and Triassic) in great detail.
Word "Jurassic" is mainly popular because of Jurassic Park movies. Funny thing is the vast majority of dinosaurs featured there were actually from Cretaceous.
@@Konservator69 Yeah Cretaceous Park doesn't really have a good ring to it.
@Vaals Or the other way around. Imagine a Jurassic park without Tyrannosaurus or "raptors", whatever specific genus those animals represented.
@@martijn9568 The "raptors" in Jurassic park are based on Deinonychus antirrhopus.
@@vaals1942 cause we aren't used to it Jurassic didn't mean much before the movies either
One thing find extreamly fascinating and that is not very much talked about, is that during that hot age when the poles where temperate, it would have been an even more alien world there than just differnt life. Because at the high tatitudes you basically get a year long day and night cycle. A summer in which the sund never sets, and a winter that´s a night that does not stop. That must have been absolutely fascinating.
I can imagine that would explain the prevalence of deciduous trees across the world.
Why keep leaves if the dry season is permanent night??
And the predators would most certainly need to evolve mechanisms like tapetum lucidum like cats, because a 3 month long night is a dangerously long time to be blind.
This really elevates the words "Jurassic World"

My man cant remember a movie title 😂 its Jurassic Park 😂

You really are one of the best content creators on CZcams. I look forward to your videos on this channel, and your AstroPro channel.
Thank you so much for doing all the hard work that goes into each and every video that you make for all of us. I really appreciate it because your smart, professional content is really a breath of fresh air on CZcams. I hope to see you hosting shows on NOVA or something like that one day! Thanks again!
This last year, I've been consuming natural history videos like my life depended on it, and this video helped plug some of the gaps I had in my understanding. Mass extinctions are scary, but in a way, they've seemed to act as a means of resetting the biological status quo, letting different groups of animals all get their time to shine. I wish some pterosaurs managed to survive, they seem so freaking cool.
I just want to say thank you for including your sources in the description! Not enough CZcamsrs do this
Dude You are Still so Much Underrated imo.
As a Nature and Space Nerd, Your channels are so precious for Me and I Enjoy whenever you post a Video.
Great One as Always❤️
Sorry for Bad English ( it's my Second Language)
The lepidosaurs, therapsids, and temnospondyls didn't go extinct, but filled smaller niches.
As a Geography and Biology Student I really like your channel, you make some of the best and most detailed science videos on the Internet and always include proper sources and further information, HUGE thank you for that !
7:49
Temnospondyls didn't die out during this extinction, They survived until the Early Cretaceous
It is possible that living amphibians are also Temnospondyls.
Wow Atlas Pro this might be my favourite video of yours yet. You're a total inspiration and actually because of seeing your success I've decided to start making videos too! Keep grinding, your hard work clearly pays off!
nice
good job. I love Atlas Pro
nice one g
nice bro
Well you could not post the exact same comment calling a video "my favourite video of yours" every time he makes a new video tho
That seems just.. wrong
Thanks for the great video. Quick addendum to the part about ocean acidification: Not only the sulfur from volcanic eruptions caused the pH to drop, but also the CO2 itself. When CO2 dissolves in water, part of it turns into carbonic acid, which lowers the pH. This is the main reason why ocean pH has dropped from 8.25 to 8.14 between 1750 and now.
Love this video because it's like things are starting to come together more, w/ this being like a prequel to the biogeography of dinosaurs. Your videos always make me curious about more so this is filling that
I love your videos. No pesky Brit accents to distress/amuse me (and thus distract me from the subject matter) but solid info. Kudos, and thank you! This subject absolutely fascinates me! Starting from the first James Michener novel I read, back in the 70s, and have loved learning the most minute details of our planet and how it's made, what makes it run, ever since.
One of your vids I particularly enjoyed was the one with WAYYYYYY more water than has ever been on Earth, because at one point I had a story idea along those lines; I tried to flesh it out using a topographic map that I scanned in (it was LOOOOONG before the www), and then manipulated photographically in various ways. I think what derailed that entire train of thought was 9/11; after that I just sat in a comfy chair and read Regency romances for a couple years, I was so traumatized just from seeing it on TV.
Love how this speaks to some of the changes we currently see in the global biosphere. And that whatever disturbances the Anthropocene creates, including our own possible extinction, new forms of life will emerge. Maybe even dinosaur-like creatures will rule the world again.
I would replace the words "possible extinction" with "probable extinction".
Yeah, there are some startling parallels between our time and the T-J transition. I think the scary thing is the difference in timescales - a couple centuries, speaking generously (more like a couple decades) vs the span of several million years. Only the hardiest and most generalist species will survive the anthropocene, even if we are able to turn the trends around overnight. With multiple projects seeking to genetically de-extinct species which humans drove to extinction, it is certainly the most "interesting" time for evolutionary history that's ever existed. The Tree of Life is going to get very fucky, very quickly.
I agree, the parallels to anthropogenic climate change were haunting. realistically though, humans are uniquely adaptable to different environments among living species and will likely be able to adapt to new niches most effectively, probably alongside other very adaptable species like rats
@@ScottysHaze Maybe over a period of a few million years it’s “probable” humans are easily one of the most adaptable species. For god sakes we literally inhabit almost every climate zone. The world getting hotter, greener and likely wetter is something we can adapt too. Our biggest threat to ourself is literally ourself.
@@ScottysHaze Humans are very hard to weed out with their bunkers and technologies.
extinction probably not, catastrophe definitely
Perfect timing i was looking for a video to watch while eating
God am I always delighted to see an upload from this channel - the excitement I get is always matched with the immense quality of your work. Keep it up, you're one of the best in the game!
Atlas Pro, the master of map-based presentation
I do kind of wish you at least mentioned the Permian-Triassic Mass Extinction Event as a side note. Oh well, other than that, it was good video.
No matter how many times I've learned about it, still nice to listen this topic again.
I remember watching walking with dinosaurs as a kid and the first episode was in the Triassic. They gave a quick mention of the extinction level event that waved in the age of the dinosaurs but this video basically sums it up in detail. So basically the splitting up of the Americas and Africa/Eurasia caused ripple effects through millions of years that caused the collapse of the entire bio chain.
Regarding as to why the dinos survived and other major groups died out its quite easy to see from that first episode of walking with dinosaurs that those mini raptors were on another level to the rest of the sluggish and oversized reptiles. Although I still find it hard to believe that 90% of life died out during that time.
You appear to have confused the Triassic-Jurassic-extinction and the Permian-Triassic-extinction with each other. The later is the one were over 90% of all life died.
Also, you are aware that walking with dinosaurs is extremely outdated at this point right? As entertaining as it is, you should not treat what it depicts as fact.
@@tjarkschweizer yes I’m aware that it’s 20+ years old. And it’s still the best representation of those time periods.
I’m talking about the 250-225mlyrs ago boundary that was the Triassic to Jurassic period.
Walking with Dinosaurs was actually WRONG about how dinosaurs were “on another level” than all the other animals. They WEREN’T. The “inferior” animals like the rauisuchians were NOT “sluggish and oversized”, the documentary made that up to make the dinosaurs look better. In reality the pseudosuchians including the rauisuchians had all the same advantages that the dinosaurs did, up to and including being warm-blooded and even bipedal in some cases.
It’s actually one of the worst Triassic representations ever, not even remotely close to the best.
I remember when I was searching a video about pangea and how I found this channel. In a few weeks I watched every Video and learned so much about Biogeopgraphy. Your work is amazing and everytime you launch a new video I'm happy to watch it
your research is maaad solid
This channel came outta nowhere for me and now I've watched like half your vids in 2 days. Great stuff on here fr.
I really like AstroPro, but I didn't realise how much I like these videos on good old, Planet Earth!
Please keep doing what you're doing. I honestly did not learn enough in school so your videos are extremely enlightening
Awesome video the Triassic-Jurassic boundary extinction is one of the least talk and understood extinctions since very few people has videos on it.
Also very cool maps remembered me the Peleoatlas project.
Just wanted to let you know you have some of the best videos on all of CZcams. They're always informative, entertaining and beautifully put together. Keep it up! I'll watch pretty much anything you post!
amazing content as always my friend. You make my love for geography blossom even more.
and by supporting world anvil, which I've used before as an avid RPG DM and player I can see how much you're improving.
Such great content. Feel like a child again watching wonders on the Discovery Channel. Thanks for this! 💚💛💙
1:32 It would be somewhat misleading to think of the formation of Pangaea as the defining event of the Triassic considering that Pangaea was actually formed earlier, perhaps by the Carboniferous, and was already in place by the Permian at any rate. Indeed, one of the suggested causes for the end-Permian mass extinction which marked the beginning of the Triassic is that the formation of Pangaea might have reduced and exposed coastal ecosystems leading to a decline in marine life.
Nope, end of the permian was caused by a large magma plume, a massive flood basalt eruption. The remnants being the siberian traps. Maybe the end of the carboniferous has more to do with the formation of pangaea because the carboniferous ended with the large rainforest collapse which could be due to mass desertification due to all the landmasses coming together?
@@eggrollsoup The Siberian Traps eruptions are indeed likely to be the primary reason for the end-Permian extinction event, but given the severity of the ecological collapse several contributing factors have been suggested including the formation of Pangaea and the resultant reduction in shallow marine environments. I'll quote from the abstract of "Carboniferous-Permian paleogeography of the assembly of Pangaea" by R.C. Blakey: "Epicontinental seas retreated from the elevated Pangaean landmass resulting in diminished shallow marine environments - a possible early event that may have contributed to the great Permo-Triassic extinction event."
The worst thing about this channel is that it doesn't release videos frequently enough :D
LOVE these videos on contextualizing the mesezoic! More Please!
>57 seconds ago
If I was any earlier, it would be the Precambrian.
Hahaha
I always learn fascinating things watching your videos. You have such an amazing way of teaching. Keep up the good work.
This is sooo good! Great video! I learn something new evertytime you release a new vid!
Drepanosaurs were the cutest not-a-real-lizard lizards. 🦎
Bro I love the video but that music at the start was not ittttt. Lots of love tho, channel is amazing
Are you called thecopydogs1185 because you leave your negative and unnecessary comments multiple times? I'm just wondering. I mean, because to me, leaving negative feedback on free content is just not ittttt. Why not try to reframe your feedback so that it reads as more positive or constructive? Think before you type.
Great video! I've got a fascination with orogenies, and this scratches that itch. Also, the WorldAnvil sponsorship is a great fit, I've been a WA subscriber for a while
Always love Atlas Pro’s quality, keep up the excellent work
Lepidosaurs also did survive and a few tebnospondyls did too but they went extinct in the middle of the cenezoic and the therapods survived in the form of mammals
I’ve been watching you since the beginning. Still my favorite channel.
"How Geography Ended the Triassic" is still a video I'd have clicked on.
A truly great video,i can'help but be fascinated and truly enthralled by your videos explaining the earth's evolution.
This is the best videos to watch before bed. Calm, soothing and informative.
Man your videos are really interesting i could listen to you for hours!
Boy let me just say that i appriciate your videos, they tickle that hunger for knowledge i have so damn good! Thanks :3
I would like to point out some errors that I saw in this video.
First of all, the first 20 seconds are a bit misleading, 150 mya was the end of the Jurassic period, you should've said 200 instead, since it's the very start of the Jurassic.
Also, at 2:15 you threw a bunch of names and made too much confusion with their taxonomy:
- Phytosaurs, Trilophosaurus, Drepanosaurus and Tanystropheus are not archosaurs (not every Triassic reptile is an archosaur...)
- Rauisuchia is a clade containing many of different archosaurs, not just one animal.
- Then Crocodylomorpha is an enormous clade which also includes Aetosaurs and Rauisuchia
- Ornithosuchus is an archosaur, while all the others I didn't mentioned are also archosaurs.
And then as others pointed out, at 7:49 you say that those animals went extinct, but it's not true:
- Temnosondyls survived until the Early Cretaceous around 120 mya, so not all of them went extinct, also Lepidosaurs never went extinct, all living reptiles that are not crocodiles, turtles or the Tuatara are Lepidosaurs.
I see there's a lot of work in your videos but the fact that in most of your videos where you briefly talk about extinct stuff there are always some errors that can be easily avoided by making a bit more research.
I don't know if you'll see this comment but next time you'll want to make a video regarding these topics, it would be better to check your informations and sources, cause your other videos regarding others topics are very well done, like the video on the Hawaii, my personal favorite. Hope this will help you improve your future works.
That sponsor at the end was LITERALLY the EXACT fucking thing I was thinking I needed before I clicked on this video. I literally clicked on CZcams to find a video that would help me with world building maps and I found your video so I clicked on it bc it intrigued me and boom! Exactly what I wanted
Great info & graphics .. thanks.
The graphics in this video are excellent, and I love how you superimpose our current maps over the ancient ones. I’m fascinated by the way the supercontinents have come together and broken up but it’s hard for me to visualize in animations because of unfamiliar boundaries.
I’m going to have to come back and rewatch this one on a slower speed, so I can really enjoy the effect!
Definitely the coolest sponsor tie-in I've seen in a while, not to mention one I hadn't heard of before. I'll need to check them out.
Grade A sponsor, too. Thank you for highlighting valuable tools for your audience, instead of shilling mobile games or VPNs.
I've missed these videos so much in the past few months.
your chanel is the best chanel i watch on youtube. Hands down. Thanks for that.
I think its easy to forget just how much geology shaped the earth and its inhabitants. The jurassic came in perfect as the world started to split up. Dinosaurs adapted and diversified.
Thanks for the awesome content!
I love the woodwinds in the background of the intro lol
thanks for summarizing
wonderful video! i love learning
After all, all geological eras are just "passing by" eras.
World don't stop.
But it's always fascinating to see how our world changes through years and eons.
I love these ancient geography vs biodiversity vids bro. Keep em coming!!
My Day just got 100% better
Might be an odd question but what did you go to collage for? I love this kind of stuff and want to go for environmental studies so I was wondering if some of the classes would be the same :)
Ever considered doing a video about something like the spread of different cultures and civilizations I know you did major empires but maybe one about where different cultures evolved and where they spread to and when similar to where and when food or pets evolved/came from videos you’ll have a bit more to do to track the different variations in cultures and where the cultures spread too not just originated from but I think it could be a really good video idea
Can't wait for the next video, found your video on hawaii exceptionally interesting.
Neat little video, not as good as the longer more passionate ones but I can't complain about an Atlas Pro upload
The formation of Yellowstone would be an interesting video seeing how it changed from before it erupted and after the last time it erupted and to how it is today
That’s a good one.
@@justinmatthewmenorca459 ty
Good video. That World Anvil got my attention, I'll check it out.
How on EARTH did you get those visuals of Jurassic Earth? Did you make them yourself? Is there a source online that you easily locate the map you used for the model of Earth?
Fun fact: When all those creatures and plants thrived at their best the Co2 levels was well over 5 times as high as it is today..
And this is of course regardless of the permian-triassic and the triassic-jurassic mass extinctions that some people like to mention. Those had nothing to do with that fact since those extinctions was because of an explosive rise to waaaaaay higher co2 levels.
Hey Kaelan, a suggestion for a video: Biogeography of a more island-ed (having WAYY more islands, something similar to what Japan looked like in the Columbian map in Alt Hist Hub's latest vid) world if the continental plates continiued to divide after the end of the Permian extinction, looking similar to Indonesia but on a way larger scale. Focusing on time periods either around the end of the Cretaceous or in our times. Hope somehow this reaches you and you think about it. Continue with the amazing videos, much love from the Balkans !
As a former althisthub fan, I reccomend Balkan Odyssey.
Awesome vid man! Loved it!
I've subscribed & turned on notifications, yet CZcams will not notify me that you posted a new vid. I only learn of new vids if I happen to check your channel.
I love world building and your work, this is a dream come true.
Glad you made a video on dinosaur origin space.
I commented that on your pets origin video
I would love to see a video about Mauritius and the underwater waterfall! Love your videos!! ❤
never seen this familiar history presented so fun and simple.
I fell in love with ur channel n ur obvious love of what u do , such an interesting subject ! N very ❤❤
Thanks for a great video! Could you put links to all parts in the description?
Fantastic video! I'd say it's definitely one of your best in terms of story arc and visual presentation! Your scripts are spot on, your diction smooth & unique, and your material is engaging and captivating. It's always a pleasure to watch your videos - I don't even speed them up, which is rare for me.
My only (pedantic) complaint is the adjective 'insane' used where you should use 'profound', 'incredible', 'amazing', 'spectacular', or any other adjective or adverb that actually means what you intend to convey. 'Insane' is heavily abused and overused, and doesn't actually mean what you're intending to convey. I understand that English is a fluid language, but that doesn't mean we shouldn't use the right words. ;)
Is it me or does this guy the best vocabulary and speech patterns ever? Excellent pronunciation and good language habits. What school did he go to?
This was absolutely fascinating! I never thought about how it was the breakup of Pangea that directly led to the climate change leading to the jurassic.
I do have a request: Could you make the videos with a higher baseline sound? I struggle to hear it, and have to turn on closed captions.
Very suspicious that I was in a university lecture learning about this, and as it ended I got a notification for this video....
Nice to learn more about that period, great video!
One of the best channel if you want to learn something new
Saw the thumbnail and 2 minutes ago, thought I could be...12th to comment. LOL. Well done, sir. Your content is top quality.
Awesome video.
Glad to see you posting regular videos now.
Your videos are the best
Amazing and interestingl video!
Keep up the good work man!
i should be asleep but i couldn't help myself i love these videos
Hey Big fan of your work, new to the channel. I had a request, I have been fascinated with the visuals of upper Africa. One thing i noticed and haven't been able to get a clear answer on is; There seem to be, at least through my eyes, evidence of water flow on the upper and upper-western regions of Africa. Could you please elaborate on this for me. The video you made on how africa was green in the recent past was great but it didn't answer my inquiry.
I really injoy These videos 💯🔥💯
yes!! my type of video!! more on the geological era :D
"All we need to do is travel back in time" yeah sure lemme get my Tardis real quick
