"During the dinosaur's" really, Is English optional now?
Great 2nd chapter! Thank you so much!! 😎🫶👏
@@dogwalker666 *Dinosaurs... not possessive, just during [the era of] the dinosaurs (plural).
The irony is fantastic. Chef's kiss.
Love Astrum
@@dontactlikeUdonkno Still terrible English I put the apostrophe in as a suggestion, They forgot to add "Age of" For a channel that are supposed to be science communicators it's terrible English. So what else did they get wrong?
Nothing like finding out youtube hasn't been showing channels in your subscriptions list again. Seems they're pushing Shorts hard instead of what we actually subscribe to.
Yes exactly
If I open RUclips on a browser (Firefox), I can disable shorts. This change removes shorts from my phone too. But it comes back in about a month.
The TikTok effect
Oh, like anyone would believe Elephants are real. A creature with a giant tentacle in the middle of its FACE?! Come on.
Thanks for the laugh.
Ive seen one.
I can confirm they dont exist.
And don’t even get me started on NARWHALS. I genuinely only learned they are real very recently. 😂
Very gracious of you to call it a tentacle. I looks more like something that most males have
Now you know how the enemies of Hannibal Barka felt like when he crossed the Alps with them XD it wasn't oh lordy that big mount can do some damage, it was AAAAAAH A MONSTER
Dear Aliens, on your next journey, could I hitch a ride? It isn't fun here anymore.
Last time I was this early, Gondwana was still in one piece
Oh coool! 😂
Oh that's where Joe Biden was born.
Grond-wana
I'm surprised nobody is talking about the pangean-gondwana war going on. The Pangeans are trying to squash the Gondwana religious groups that emigrated over and combat has broken out over the last few months. Horrible stuff.
@@vileluca 🤣🤣🤣🤣
It seems like you went out of your way to name drop the less popular animals etc and I appreciate this!
I was thinking of Stephen Jay Gould's book: Wonderful Life. He would be delighted with you, I think.
Consistently one of the best channels on all of RUclips. Fantastic bite-sized videos, great subject matter and great presentation. I rarely send money to RUclipsrs but I just love your Channel
Dragonflies, and a lot of bugs, absorb oxygen through the surface of their body. So when oxygen levels got close to 40% they were able to support a much much larger body.
ehhhh…*partially* true, but the main reason they got so big was because there weren’t any other flying animals to compete with. you can see this by how paleodictyopterans and griffinflies survived into the Permian.
@kane2875
That’s a good point.
That’s not funny, I’m not going to sleep well tonight!!😅
Giant male dragonflies injecting procreation fluids in female dragonflies brains, what a thought.
I think with the odd shaped creatures, you have to consider we largely do not know what a creature's soft body may have looked like. It's not my field directly, but I have been an animal artist my whole life, and odd skeletons like the dimetrodon are structural elements for very large and typically aquatic animals : see whale skeletons. While there are many complete skeletons of ancient animals, the vast majority are very incomplete. For instance we only have the jaw of that shark you were showing, if you look close at the graphic you use, its just a great white shark with the saw mouth superimposed.
In the planetary videos you were always careful to mention when something was an artist's representation vs actual photo or scientific data,, which was very helpful for me to get a realistic understanding astronomy I feel like this other educational videos you should try and strive for the same. No shade, just a bit of my opinion!
Great perspective!!
I think it's pretty obvious in this case doesn't need to write on every representation that it's an artist's impression based on the reasonable guesses unlike space where we actually take images.
@@mattsmith5421 while it may be obvious to us, its always good practice to label something clearly. in a lot of the astronomy videos something that was clearly a 3D animation to me was still labeled as an animation which certainly helped people other than me to understand the actual limitations that we face when trying to film or photograph spacetravel
@@Xylophytae I know when videos are animated and understand that we don't know exactly what things looked like. I am working class with little business and art college credits.
@@mattsmith5421not completely. I am not sure what a fossil of the animal looked like from which this artist’s impression comes from. I would love to see a side by side comparison along with some similarly recreated fossils of modern animals for reference.
Great program, could easily be extended to an hour, so much information to absorb. Good graphics too, gets more realistic over time and the details of tectonic shifts are really well done. Great job, Alex! Since I was a child in the 60s I've wanted a time machine so I could scroll through earth's history just like this! Perhaps I was one of these alien scientists....?
those alien siencists need to return as soon as possible so I can enjoy another video like this one! I need more, please. Great job as always :)
It might be time for them to intervene...
I am also curious to know about the smaller creatures of this ancient past, such as small insects. I also feel like I am missing some information about how these first mammals came to be. I am curious to know more about it, and also the predictions of the movement of continents in the future. It's super interesting!
I think small insects are hard to find out about since they don't really fossilize well, so we can only rely on amber.
One of my favorite insect history facts, is that ants have been farming crops, as well domesticating other insects for mmmmillllions of years :)
I'm more curious to know about the prehistoric *Tress and vegetation* ...
PBS Eons here on RUclips is a treasure trove for information like that. But the gist of the mammal question is this: Dimetrodon and others are what are called "stem-mammals" because they were sort of a transitional stage between reptiles and mammals. They weren't direct ancestors to modern mammals by any means, but they got the ball rolling. Over time, evolution and adaptations changed these stem-mammals into more overtly mammal-looking creatures, like Synapsids and other mammal cousin groups. Eventually, what are called "crown group mammals" emerged, and those are basically the "root" of the "mammals as we know them" tree.
There seems to be an obsession with CO2 as the driving factor for most changes to climate on the planet. Sounds like propaganda more than science.
That dimetrodon footage was top-notch.
Love this. Beautifully narrated and great visuals. The Opera browser endorsement at the end may be one of the few endorsements which actually fascinated me - what a modern, intelligent browser. Thanks a bunch.
Thanks for keeping the channel fascinating and interesting 🙏🏼
Wonderful work, Alex! I wuld love to see more, most certainly!
Videos like this, the planets and the universe are fascenating to me. Thanks Alex.
Totally loved this. Can't wait for the next part!
Thanks Alex, for another superb video! Oh! Please pick up where this one ends and keep right on rolling. I know the end of the dinosaurs is a complicated subject, but I believe that you can give us a satisfying rundown to ponder and then move on. Also, I was wondering, who’s at the forefront of the new-ish work placing mammals earlier in the timeline? Any links? I’m sure we are “about” to see some more mammals come and go, in the next chapter(s). Hint, hint! And, thanks again-it’s a “crazy-ton” of work you’ve already put in! ( Hopefully, you are familiar with this unit of measurement! Lol! Thank goodness we don’t have to stick to perfect English when we speak, or casually communicate, like comments and texts-it does seem to make it more real and impromptu. I mean, holy cats! If we did these things perfectly, everyone would know exactly what we were trying to say, and there would no longer be a need for emoji’s!! Can you imagine?! Oh, the horror…what would become of them?! 😉 )
totally addicted to Astrum.
i've never subscribed to any RUclips, Twitter, FB ect ect. content before....
but it's totally worth supporting this channel and content.
Loved this!! Please make this a series!!
Appreciate the great research job behind this video. Also the visual rendering is excellent.
Well done!
Greetings,
Anthony
I cant wait for the part where they come back and humans are gone. Kinda sick of us tbh.
I love you creativity and production quality 😊
How about an extinction that might have happened when the earth was covered in ice? Did that compare to the one you mentioned here?
Thank you! Excellent mini-historical documentary presentation.
Fantastic video thanks. Love this Earth history series. I'd love to visit early humans!!!
Fantastic episode as usual!
This was a fun video. Please also do one about the (potential) future of the earth and it’s inhabitants.
The future is a world just like Singapore. Where you must smile everyday and you can't chew gum. 😂
The sun will cook it and probably swallow it.
A video about the future history of the planet and its inhabitants would be great!
I really appreciate that he uses footage from films and stock footage instead of just using AI generated images, I've seen far too many youtubers using AI lately and it's disheartening. Good on Astrum for taking the time to find all the footage he uses for his videos!
Give me more pterosaurs, they're so cool
Please bring this series; into encounters with early humans and maybe even historical interactions with known time civilizations. Working with a historian could bring many even more detail and understanding while paired along the scientific and speculative. Another fascinating look would be to follow this through and maybe even a closer look through time. The oxygenation period of early covered in trees newly evolved with no lifeform there to break them down, so the trees scour the forest floor until creatures learned to eat and break down the new material, the hardy and fibrous wood. Either way great work!
maybe even, maybe.even, maybe even...Jeez!
Great video and informative and entertaining! Had a great time!!! Good luck to you and the channel!!!
Thank you! Excellent mini-historical documentary presentation.. I love this series! Thank you .
My daughter had asked me, when she was younger, if i thought it was possible that another species from a far away planet came to earth or sent a probe when it was a snowball and didnt find anything. But in doing so, left some of their genetics behind and thats how we started.
She didnt word it exactly that way, she like 10.... but that was the point she was making. I mean anything is possible in the realm of things we have yet to discover.
she's right .. life of all types are transfered/ migrate, from universe to universe, there are billions of other Universe's out there, apparently a small percentage, contain life as we know it.
Excellent series about earth’s evolution! Congratulations it is awesome!! All the best
Also, ancient Earth was 720p with a very low polygon count, and you would never see more than 30fps.
I love that every time you show spaceships, you bothered to find new ones
You just blew my mind Astrum
Me too😂😂
Brilliant video, thoroughly enjoyed it☄️
Oh my god thanks for uploading this, I was already running out of videos to watch to fall asleep. 🥰
One of my favorite videos from you all so far
Creative and beautifully done!!! Bravo. This was very entertaining
Awesome Documentary, I can't wait to see the Next part to this adventure. 😎👍💯
There is actually a theory that the Permian-Triassic mass extiction WAS caused by a large asteroid impact. The Wilkesland area in Antarctica is likely an impact crater 500 km in diameter that was caused by an asteroid with a diameter of 40 to 50 km. For comparison, the Chicxulub asteroid which wiped out the dinosaurs is thought to be "only" 10 km in diameter.
Is is thought that the Wilkesland impactor not only killed a lot of species directly, but it also caused worldwide volcanism (especially at the antipode point in Siberia) which was another main cause of the mass extinction.
un impacto tan grande debe de mover la inclinación del eje terrestre ...
Climate change killed the dinosaurs

Always love your content 😊
I liked this series. Please pursue it further
"Let's enter a submersible, and dive in"
No, I'm not getting in that can until it's been tested
Really enjoyed this!!!
Thanks so much🖖❤
Fascinating series❣️ So, how many Tectonic Shifts and Mass Extinction events will occur before the next episode? 😅
Its just so few dino species of concensus for so much time they want it to represent .
Very respectful start announcing the vagueness of this mythos
Great series, would love more :)
I love this series! Thank you ❤
If the aliens come back now, they can stay with me. My couch folds out.
I love your channel Alex!
Not watched it yet but already liked the vid.
What an incredible program, learning much…thank you
wow !!!!! you are creating cutting edge, scenic videos with an extremely pleasant voice ! 😍🤩
Thanks Alex excellent video. Could you explore the Paleolithic era?
I'm already excited for the third chapter.
The Karoo Ice Age, also known as the Karoo glaciation, was a major glacial event that occurred during the Late Paleozoic Era. I am interested in the Karoo Ice Age and what the world was like then.
Very good video and story !!!! 👏🏻👏🏻👏🏻. Greetings from Colombia 🇨🇴
Mexico. Hola.
Even the Opera Ad was entertaining and interesting!
5:00 Unfortunately for the aliens, they thought Stockton Rush seemed like a nice guy
Ermm... too soon?
Really
Did he just call dinosaurs reptiles?
Everyone knows they're actually slimy lizards
*Very good! Entertaining and informative!* 🦎🦕🦖
your videos are amazing~~~
Just a million years boggles my mind...a billion I can't even fathom.
Great content and presentation. 😊
Alex, you’re a master storyteller ❤
The largest extinction was not the Permian, it was the great the great oxidation event.
Agree, in that while the Permian extinction killed about 70% of all life forms, the great oxygenation killed more than 90%.
Everytime I watch a holiday ad or property ad I see so sign of the earth being on fire.
I'd love to see another Video about the continuing Blood Line of the small mammal that looked like it was going to eventually leaa
2:46
Man were there states even back then?! Truly amazing
Having read Bill Bryson's "A Short History of Nearly Everything" three times now, I am absolutely convinced we as a species haven't got the faintest clue about ANYTHING. This scientific arena of human endeavor is merely entertainment - much as a circus ring - both for the performers and us plebes in the audience.
Have you tried reading something else?
High quality imagery and content.
Fantastic video. Thank you.
How about a piece on the discrepancy in proposed age of the universe implied by the JWST?
We are barely a few months in the anthropocene age and it seems like it’s going to be a short one the way we are going hahaha. Imagine the aliens surprised when they discovered our remains
not that this is boring,stayed awake watching when im super tired cuz i was interested, but you should do longer form videos…like an hour, i could definitely fall asleep to that lol
Better than your videos. I just watched one of those.
Thank you always best work
I know of a point in time called the boring billion, or boring million. I remember watching something on it quite a few years ago. I am wondering if there has been any new insights into earth's history and if you could perhaps summarize it with the alien visitor flavor as these are great for my kiddo to learn.
Absolutely love your videos man, fewer good science channels out there these days but you never disappoint.
I enjoyed the Dimetrodon! Very lifelike!
I love the late Permian!
Keep it coming
Well done sir. Very well done.
They're cool😊
280mil years ago - a little more than one rotation around our galaxy 🌌
really great videos 👍👍
So i know you already commented that a lot of your models are contested, but there's pretty good evidence that a decent amount is dinosaurs actually were warm blooded. A lot of your information is really dated.
Yeah, since basalt is by default more dense than astenosphere, without immense heating from a riftzone it will always sink, and generate immense volcanism. Pangea and Panthalassa was screwed from the moment it formed.
Got to love a good thought experiment.
I miss you, dinosaurs. :(
I miss them trilobites 😪
Plot twist : The Aliens are actually time travelling humans from the future
Thanks Astrum
The great oxygenation event is arguably a bigger mass extinction event than the great dying
There are thousands of different avatars through out the universe. Alantans, Lamerians, where 1of the races on earth. And are still here. The shift during Noah time also contributed to the shape of the landmasses
man, this earth planet is crazy
just found this channel. so creatively put together. great graphics! calm but excited narration involves us easily. thanks so much!! going to watch the first one. :) 🌷🪻🌱
Can you do more about "prehistoric" microbiology?
I cannot imagine the stench some of those bigger dinosaurs might put off. It be cool to revisit history time machine style, but I dont think my senses could handle the primitive world.
