[@Dragrath1]

@@joshuabanner3675 Hard to say mass extinctions on Earth periodically wipe out specialists and species high on the food chain. Typically all the big stuff dies out leaving small generalists to re-diversify into the now vacant niches. Predatory clades that don't retain some omnivory don't fare well in particular. The real winners where though will likely be based on which creatures adapt to better maintain moisture thus far his forests are wet and these creatures seem to be quite adapted to reproducing in swampy environments which means moisture retention isn't a big problem for them. As stuff dries out a lot of them are utterly f**ked if he is basing things off the Carboniferous rain forest collapse as he seems to be largely. The then dominant flora largely went extinct Lycopod trees(Isoetopsida) dominated throughout the Carboniferous rapidly growing to towering heights before branching out but they relied on spores nowadays quillworts are the last living descendants of these ancient towering giants. Their competitors the progymnosperms actually beat them to the scene with large spore bearing woody conifer like trees but were out competed until the climate became drier and the surviving taxa which by then had evolved hard seeds and thus could live in low moisture environments. These plants grew slower but filled the full canopy thus making things far darker and driving a whole different ecology. Amphibians and "Sea Scorpions" didn't fare well among animals and largely died off with the surviving tertrapods being a lineage of amphibians adapted to breeding in ephemeral water and of course the Amniotes. All these survivors went on to diversify into fascinating forms but pretty much all of those were F**ked when flood basalts burned Carboniferous coal and releasing a shit ton of volcanic gasses and collapsing the late Paleozoic Ice Age sending the world into a hothouse climate for 260-33 Ma. Synapsids the then dominant terrestrial vertebrates including the mighty Gorgonopsids and other Therapsids ruled the Permian occupying all sorts of niches but in its collapse were nearly entirely wiped out leaving only a few small forms behind of which only one would survive beyond the Triassic the cynodonts. The reptiles particularly the stem Archosauromorphs fared far better and would dominate through the next mass extinction with one group dinosaurs particularly dominating the planet. They remain the best adapted terrestrial vertebrates metabolically mammals can't come close though they were far more diverse than we used to think. If it wasn't for a extremely unlucky asteroid impacting into the rich hydrocarbon deposits of Laurentia/North America's continental shelf blocking out the Sun killing everything dependent on the primary food web they would still rule the world. It is largely the same deal for Pseudosuchians crocodiles and their extinct cousins which ruled through the triassic and largely were wiped out only to recover and rediversify untill they were ended by the K-Pg extinction. Look at how they occupied practically everything at one point or another Armored Herbivorus Aetosaurs and bipedal carnivores like Postosuchus of the triassic to the streamlined fluked marine reptiles of the Jurassic and early Cretaceous to catlike terrestrial carnivores, and armadillo like vegetarians, yes they even evolved herbivory more than a handful of times with small herbivore niches partitioned between them and mammals. Ultimately if didn't matter only the secondarily ectothermic modern crocodillians survived the rest like most mammals, all the nonavian dinosaurs and non benthic marine species if you didn't have a low metabolism, feed on a long lasting cacheable food source such as seeds while being small or live in a detrital environment you went extinct. I think it is no surprise that Cretaceous primates (which yes were a thing) were basically the Mesozoic counterpart to modern ground and tree squirrels. It also isn't the most innovative creatures either Have you ever heard of the Weigeltisauridae? These were the closest Earth has ever gotten to a European dragon having managed to develop novel gliding wings supported by bone. Every other gliding or flying tetrapod has modified ribs or arms to form their wings but these guys straight up grew wings. Didn't help them survive the great dying however when their insect prey and tree habitats died out they did too ending the dreams of dragons on Earth. Prime candidate for alternate evolutionary history timelines however. ;) This has gotten long winded but the point is it isn't just about how well adapted you are it also depends on how lucky you are.

@@pokemonareawesomeful Well, they could. A jumping tree-dweller would profit from something that protects them from falling to their deaths. Like, perhaps they start by spreading their legs out when falling to get more air resistance. Those then begin flattening out and becoming gliding surfaces over time, which eventually grow large and muscular enough to allow them to fly, at first just when falling off a tree to get speed, then later on out of their lunge.

Heres an idea: Since we have a tree-dweller who attacks by lunging, make them evolve wings. Theyd spread their legs out to slow their fall, which increases their survivability. Some of the feet would eventually evolve to flatten out, allowing them to glide from tree to tree and fall slower. As their wings grow, eventually, they would grow the musculature and internal structure to be able to fly, either by throwing themselves off a tree or by lunging into the air.

[@danieldomeisen2632]

I would still love to see a species of your heavy shelled herbivores have an "Omni'skeleton", basically and Endo/Exo skeleton. This would allow them to be... very large. The plates near their 'breathing' tubes would develop the ability to expand and contract in sequence to allow a simple form of breathing. Evolving so that when one side of them is "Breathing out" (plates compressing) the other is "Breathing in" (plates stretching). This would give them a HUGE advantage in a lower oxygen climate and a higher "Mid range" energy supply as they are able to have a flat line of oxygen intake at all times due to the duel billows system they use to breathe. I would also LOVE to see the shelled creatures (i am not even going to try and spell that name, i am bad enough with english not to mention latin) go underground. Their Stalk eyes, shells, and the tentacles in the front make for near perfect burrowing forms. I can imagine hives of even 10cm ones burrowing into rock with a sulfuric acid spray from their stomach. Maybe pick up some lithovoric gut bacteria? Either way this series is freaking AMAZING, i hope it continues for a LONG time and we even get into the tech differences. Who knows maybe you can do another planet in the same system and we can see how interaction would work...

As a Greek, I find your grasp of the Greek language impressive. Every one of your species names is aptly descriptive.

[@fluffernal]

2 years late, but the dude also makes conlangs, so he would obviously be pretty knowledgeable on other languages

[@electrophoenix7977]

Ok, I know you have been rather busy with your life... at least, that's what I assume But SHEESH, FINALLY! ANOTHER BEAUTIFUL EPISODE OF THIS BEAUTIFUL SERIES

[@evanswart480]

no

[@jasonlewis4438]

He makes other kinds of videos you know...

[@reeceshugrue6167]

@Mini Moustache No offense intended but, those videos are nowhere near as entertaining as these videos.

[@evanswart480]

Reece Shugrue no, I prefer those videos and I hate it when people get mad at him for not making alien biospheres more

[@sanguillotine]

Evan Swart cool, that means you and the previous commenter have different interests

[@Asurnasurpal]

Overwhelming my favorite series on youtube. The level of quality here is just unimaginable. Do you have any plans to return to aquatic species? I've been eager to see how things may have changed in the time since we last checked them. I also agree with some other comments here, I'd love it if you showed some of these creatures next to each other. It would be good context. But either way, I can't help but just congratulate you. This is absolutely stunning and I cannot wait to see more. I'm absolutely attached to all of these bizarre critters, and as things start going extinct I'm going to be inevitably upset.

[@martindavids1294]

I was heartbroken when I saw how long it takes for each of these episodes to come out, this is seriously amazing

[@imtfox8091]

I've watched this entire series 6 times! Please make another one soon I can't wait anymore!

[@jcon5698]

[@shannonsilvera1604]

This series is amazing, i got so excited when i saw this notification.

[@marcusfrazier4923]

I have never seen someone break down the design & evolution of a fantasy creature so throroughly. This was an amazing watch. 👍🏾👍🏾

[@comiccat4650]

This is honestly one of my favorite series on youtube. There is alot of time inbetween episodes but this for the sake of well thought out information and it's conveyed understandably. Keep up the great work and take your time!

[@timon3154]

All of these creatures are complete nightmare fuel yet I can't stop watching.

[@silver_kitten]

We will get used to it

[@komododragon8249]

Yes but these all work with our physics there's no magic powers and stuff which is good I'm tired of seeing impossible aliens species which are just massive hives of gigantic creatures which are parasites?

[@viorp5267]

13:46 No, not the sarcopods!

[@PaleozoicProductions]

Its insane how you get an immobile filterfeeder into gigantic spider demon creatures while the clade everyone half-expected to be the dominant clade only has the filter-feeder member of the clade to be ancestor of the terrestrial decendents.

[@mlpman246]

[@liamjohnston2000]

I love this series, but I have one request. In the cladograms and food webs that you make, you have all the organisms roughly the same size. You do show how large they are with a scale when you first make them, but I'm wondering if you can make a size chart comparing the organism's sizes with each other (and maybe a human as well). Just asking.

[@hashtagunderscore4898]

One day this will be a fully animated documentary, and we can all look back here, where this project began.

[@BoozMcGroove]

What’s been going on in the ocean during all of this? I feel like exploring how the aquatic biodiversity is affected by land animals (if at all) ended up changing them. That and I want to see more of the Anomalocaris-Sharks lol

[@hem9483]

[@bird2034]

Once again, your imagination and knowledge blows me away. This is absolutely fascinating, and the amount of time and effort put into this is obvious from the quality. Great job!! :)

I have been waiting for this, though it seems that my trees have yet to take to the skies. By the way, what about the ocean ecosystems. They surely haven't been sitting on their laurels all this time.

there's no freaking way your *trees* should be taking to the skies unless you're on the freaking elemental plane of air.

This series is so addicting I’m binging 1-5 right now. Keep up the good work!

[@Zakalwe___]

I’d just like to thank you for making such incredible videos with an attention to detail unparalleled on this site. Honestly my favourite series I’ve watched in years.

[@sofia.eris.bauhaus]

i wonder where the first flying animals will come from, maybe they come from the oceans! :D

[@zacharyhandy9606]

Like flying Fish evolving flight before others

[@maromeilimonei3312]

I think the elastospondyli, they have 4 semi-unused limbs, also, they're not fast, so they would benefit more from flight

[@matheussandbakk9959]

maromei limonei I think one of the Malacoformes will gaim flight first as they’re the insect counterpart of this planet, and small sizes have an easier time flying. The Elastospondyli could gain flight, but I think it’ll happen later than the Malacoformes

[@ronaldgargoyle3407]

So monkey spiders vs helicopter squids. I like it!

[@rafaelcoutinho3537]

Gliding monkey spiders

[@critiqueofthegothgf]

the presence of acid raid resulting in the terrestrial biosphere being comprised of marshes and bogs makes it so much easier for life to adapt and transition from the ocean. all thanks to the super cool inclusion of hydrogen sulfide. I love this series

[@brownie8655]

Everybody gangsta till the Osteopoda evolves in accordance to a gradually broadening diet in an attempt to gain carniverous traits and forms longer, many jointed leg-structures to give it an edge in terms of speed and agility.

[@gogwon5139]

I love this series so much, it’s so fun to watch how the creatures grow and develop

[@karlmachnow4961]

This is marvellous! Yet, I again have to wait for another episode until you finally let toxicity evolve. I think I've thought of that since the 2nd part of this series. Especially for the small malacoformes toxicity would be a huge advantage imho, as they wouldn't have to evolve a hard body shell to defend themselves.

[@benthomason3307]

toxicity? why do you want to bring 4chan and tumblr into the picture?

[@yannismorris4772]

They could also make hives like bees or termite mounds. Effectively living in structures made out of their own poop

[@engelhaust]

these videos are spectacularly made and very impressive. that being said, there is no way i would set foot on this planet without power armor and a double-barrel shotgun.
