- In this video, I briefly touch on the size limitations of the Avian dinosaurs that survived the K-Pg event and then discuss Antarctolestes Terminus, the lone surviving Non-Avian Theropod of this speculative evolution project.
This project is really cool actually!
The idea of small maniraptoran animals being able survive the KPG extinction event via hiding in Antarctica sounds genuinely realistic, god I love Speculative evolution
Dope concept glad the algorithm picked you up
in fairness, given how little we know of the fossil record of Antarctica, this is entirely possible
I am delighted to begin following this project!
are gonna more surviving Non-Avian Theropod outside of Antarctica and southern Australia in this series
Antarctolestese and it's descendants will spred and speciate in South America, Antarctica, and Australia with time, but it is the only non-avian theropod that survived the K-PG.
Can't see the comments.
Thanks TH-cam.😑
So just as a tldr is this a world where the extinction event still happened but a group of dinosaurs managed to survive in Antarctica?
Yes!
I should probably make a short video before the video on the surviving Ornithiscians video. This project will follow the evolution of the 3 clades of surviving non-Avian dinosaurs as they spread out from their refuge in Antarctica into South America and Australia.
This is such an interesting concept, I’m eager to see what comes next!
Hey man, You are doing a great job, we need more spec evo.
This is a really intriguing concept and a great first episode can't wait to see more of the surviving non-avian dinosaurs can't wait to the other survivors
Can't wait for more!
Amazing absolutely amazing. But also is it just me or has this year become like the great beggining of Age of Spec Evo on TH-cam,
Cryptadia, Project Mustelon, Project Apallo, and Kappa all look really amazing and I'm very excited that more people are bringing their projects to youtube!
Dr. Polaris' series was great, shame he canceled it for some reason.
Whenever i see a *Spec Evo* that includes birds i always imagine *SERINA: THE WORLD OF BIRDS*
it's a spec Evo about finches & fish guppies left alone on a lush planet and left to evolve into different forms over millions of years.
This is what I've been waiting for.
I love this already
I think that the Smaller *PARROTS* 🦜 alive today have a better chance of surviving millions of years into the future because of their complex diets and adaptablity.
This is pretty cool. I am a fan already.

How much is known about the fauna of the Antarctica 65 mil years ago? Did you find any niche occupiers that may prevent the dinosaur retaking of the continent? Lovely project, love it, here's a sub from another dino/spec evo fan.
The fossil record of Antartica will likely be incredibly fragmentary, sadly due to the glacier coverage. Even if all the ice melted, a large amount of Mesozoic and Cenozoic formations will likely be few and far between due to said glaciers scraping the majority of them away.
There is still a chance though of pockets and scattered regions of Mesozoic and Cenozoic rock, though, like there are on some of the islands that Cryolophosaurus was found on.
I think another reason they didn't get as big is due to competition with mammals as species like terror birds went extinct after direct competition with big cats when the American continents connected. so I think in a world where mammals didn't exist and birds didn't have direct competition they could have grown the opportunity to grow bigger then in our timeline
Terror birds going extinct to smilodon is outdated. The leading theory is they went extinct to climate change
The large South American Phorusrhacids had already been long extinct by the time that Carnivorans arrived in South America during the GABI. The late surviving South American Phorusrhacids like Psilopterus were already the size of a Turkey. The last of the giant terror birds, Titanis, lived side by side with big cats in North America for millions of years after its South American cousins had gone extinct. There's not real evidence that big cats out competed them instead their habitat vanished and they were too specialized to continue.
@@DragonsoftheCenozoic oh shit really? My bad then
To add on, a species of Smilodon did overlap in temporal range with Titanis. However, it and other sabertoothed cats were much smaller than the giant terror bird and only gotten bigger AFTER it went extinct in its habitat. Suggesting that even when carnivorans and giant phoruschracids were contemporaries, it wasn’t not one sided for mammals, it all depends on the environment.
@@DragonsoftheCenozoic
Interesting and correct as well! But there is still a point to be made that the "terror birds" were rather constrained in breeding habits, resource availability and competitive exclusion from macropredatory habits in particular. It's pretty likely that without context shifts favoring carnivoran mammals, or even the complete absence of carnivorans may have allowed them to reach truly enormous sizes (eventually)
More. More. More!
This is a really nice video, did you do all the art? I like the art style
Ah cool where can i learn more.
Heck frackin yes! 🫀⚡️🫀
Keep it up dude, also you just earn a new sub
New sub
wow ironic i see a new spec evo chnnal after seeing kappa wolrd of turltes a seedwolrd
LETS GOOOO NON AVIAN DINOSAUR IN PLEISTOCENE
Still gotta make it through 63.4 million years before we get to the Pleistocene, and it will be a rocky road dealing with the Grande Coupure Extinction and the Mid Miocene Disruption, but we'll definitely get to Dinosaurs in the Pleistocene eventually.

So this little guy is the only non-avian theropod to survive the aftermath of the K/Pg extinction in this project, while also being the ancestor of any genera that come after.
How many ornithischian genera have you decided will also pull through into the Paleocene?
Only two genera of ornithischians survived the K-Pg. I was hoping to have the video about them out several days ago, because I had all the art and script work done, but I haven't had a chance to record the audio, but hopefully I will be able to make the recording tonight and get the video posted tomorrow.
I already had my own project with Sabretooth Aliorames, Giant Struthiomimids, and some goofy ahh looking giant Abelisaurids. The Meteor still struck the but way smaller and smol dinosaurs survive.
nice
insane
Personal question to this matter : What if KPG events never happened,would there be non-avian Theropod dinosaurs that eventually became bigger than the T.rex ?
Depends on how you're defining "bigger", Length-wise, Spinosaurus was already bigger. I don't think a theropod could get much heavier than T.Rex.
Do you have a DeviantArt page or not?
Yes, here it is, www.deviantart.com/paleogeneinvader
hi when does part 2 come out
in a little less than an hour.
@@DragonsoftheCenozoic GG
did any of the disnoaurs went to south amercia in the spec evo
wolrd
They will.
so its next week we see ep 2
If dinosaurs didn't go extinct we'd have domesticated intelligent raptors instead of dogs or cats.
They evo into dragons the ancestors of birds split into another dino group i mean when the were still basically dinosaurs
Basically feathered dragons without the fire
"What if the Dinosaurs didn't go extinct?" (Who's gunna tell him about birds?)

🚬🗿👍
One thing that’s far out there, but should be investigated by serious scientist is the very nature of the planet earth itself in a positive agent of evolutionary pressures for these creatures
For instance: since modern physics have a loose understanding of gravity, it does not take for account that the gravitational forces on the earth has changed in the past that allowed large animals to evolve those forces no longer exist, and without those forces that exist that allow for dinosaurs to get to how they became, we will forever miss a port of how these forces change them through adaptation.
There is zero evidence of gravitational changes in the history of earth. Zero.
The Dinosaurs got so big thanks to the fact that they had lighter bones, and air sacks tho make their bodies lighter. That is all.
qeastne why your chnnal is name dragons of cenzoric
Many cultures have called fossils Dragon, cyclops, or giant bones. In a world where the non-avian dinosaurs never went extinct it's likely that the term "Dinosaur" wouldn't even exist given how late it was coined so I'm going with dragon for the colloquial name for surviving non-avian dinosaurs.
Sorry guys but GWAR wiped out the dinosaurs and the humans killed the surviving dinosaurs but we call them dragons
Yeah though real dragons would have six limbs in total
Let's be honest if a medieval knight saw a non avian dinosaur they would call it a dragon
Wyverns count as dragons, right?
@@Gelatinocyte2 Not really, they'd likely be the closest relatives to Dragons but they aren't true Dragons
"Real" dragons do NOT have six limbs, because they are not real. They are fictional/mythological creatures and have been depicted in various myths/stories across the globe and throughout human history to have anywhere from 0 to over a dozen limbs. Saying that a dragon HAS to have six limbs in order to be a "real" dragon is just stupid.
@@jessejarmon2100 No they are correct True Dragons are one of very few "Dragons" to be referred to as Dragons by their native people hence why they are considered True Dragons
Most creatures you think of as Dragons ain't Dragons many of them were only called Dragons by Europeans when they were explaining them to fellow Europeans
Birds are dinos so technicly not all dinos went extinct
This is brought up in the video.
Well, they didn’t go extinct.

😈
THEY DIDN'T. DEAL WITH IT.
But seriously though, this is a neat project. 🦖
