Good video my friend. By the way, could you solve my doubt about which was the largest Prosauropodiform or Sauropodiform on record from the Triassic Period. Either the early, middle or late.
@TheVividen I would love your reaction / take on Max Hawthornes most recent study on Megalodon! It show some good evidence & insight on the lifestyle of this fish! It’s a video here on TH-cam. He’s done research on Llesiosaur / Pliosaur locomotion & the evolution of Plesiosaur necks.
Your analysis is poor. These animals are used to 22% oxygen levels and would have to adapt to 12% oxygen levels a 50% cut (around Everest base camp level oxygen) over night. And as mammals have a pretty inefficient cardiovascular system anyway it’s reasonable to assume that all the very large mammals wouldn’t make it more then maybe a few weeks. Definitely not reproducing. Maybe the smaller ones could? But even smilodon would probably have been useless at 12% oxygen levels, a tired, out of breath cat that has a hard time walking in a straight line basically.
Also I had a feeling the Daedon would take it. Like pigs are super adaptable in most ecosystems and give humans trouble even today. The diverse nature of their size, intelligence and adaptability only compliments them. And other than the Miocene and when we get to the big boy dinosaur domination eras of Jurassic and Cretaceous. I really don’t see another animal being as successful as essentially a super pig loool
Daeodon wasn't terribly intelligent as far as mammals go, but it certainly outsmarts any animal from the Triassic, with the possible exception of small theropod dinosaurs.
@@adriani9432 when looking at most of earths prehistory I honestly think until we get to into the proper and more recent history of the cenzoic they’re pretty damn smart for most life on earth. Crocodilians. Dinosaurs. And even some birds having an orange sized brain is pretty impressive for them and they tend to be the most common species that could pose a threat in this regard. Again taking. The LONG view of it. Not in more specific eras
I wonder what proven habitat conquerors would fare? Pigs, dogs, coyotes, cats and bears would probably take over and then radiate to take up new niches. Hell, throw in a Bullfrog and see what happens 😂
@@DzinkyDzink I think the smaller successful mammal families such as rodents (herbivores) and mustelids (carnivores) would devastate the Triassic ecosystem, providing climate (temps) and atmosphere (O2 content) wouldn't be a significant hindrance. They'd likely quickly evolve and take over niches never previously occupied.
Many wouldn't make it, but there was Barinasuchus, a Cenozoic crocodylomorph which was basically a re-evolved version of Triassic apex predators. It would provide direct competition for the Rauisuchians.
So, mammals seem like they’re doing well. Does make me worried about how much of a menace the Cretaceous will be though, lol. Especially with T. rex around. Good video. 10/10. Can’t wait to see what comes next.
Not just t.rex, we can also mention an angry trike (which would be a nightmare even for an adult rex) But im pretty sure that mammals like the paleoloxodon or the Daedon can enjoy the enviroment
@@adriani9432would they? We now know that pack hunting wasn't incredibly likely though, so the role they'd assume would be a small, solitary carnivore, I'm assuming competing against animals like Raccoons and Possums
Wonder how some Devonian armored fish and sharks would fare in Mesozoic waters, that could be another cool video. Also any video about carboniferous insects would be rad!
This is an interesting concept In palaeo fans communities there are two completly and extreme postures, the ones who think cenozoic mammals are completely crushed and swept away by any Mezosoic "reptilian" creature because the Mezosoic was the age of the "big, angry killing machines" with superior features and on the other hand the ones who think that mammals are able to outcompete, overcame, over...all, the dinosaurs because mammals are "smarter" and "more active", those persons think that a wolf pack is able to take down medium to big sauropods.
a fun project. I think you underestimate the heat effect in nearly all cases; personally I'd drop nearly all a number, especially as unfamiliar food &/or pathogens could always turn out to be disastrous, but I'm still pleased to watch your takes
That's the catch, modern mammals may prove so effecient that they would wreck existing ecosystems and reform those around themselves. You don't need a 7 tonn T-Rex to hunt Wildebeast when all the Trikes went extinct.

Honestly, what about orcas? I dare say that you could drop 1000 orcas in any ocean throughout earth’s history which has enough food to sustain them, and orcas would absolutely dominate, or at the very least be a serious contender for top predator. A decent sized pod of orcas would be a match for any large marine predator that has ever lived.
The only animals that get a 10 in basically any era you drop them in are Orcas, Titanosaurs (such as Argentinasaurus), and Humans. Orcas with their team strategies on top of already being formidable hunters, titanosaurs being enormous very powerful land animals which were still in a time where the largest land predators to ever walk the earth existed, and humans, being the most intelligent and adaptable species on the planet. Even if you dropped 1000 Neanderthals instead of 1000 modern humans, they would easily survive and thrive, being an active threat to every other species on the planet.
Orca kill megalodon so yes orca can survive and orca is a big predator too and they hunt in pack with intelegence orca can be a treat to any Big predator in ocean
@@corneliusmcmuffin3256 yeah, orcas dominate, the only time periods where they woud have something to fear would be the neogene (megalodon and livyatan) and late triassic (himalayasaurus, shonisaurus, aust collosus potentially being a macropredator and so much fricking more, like, it's actually insane how Panthalassa was absolutely crowded with giant apex predators) but yeah, everything else is fine, in the jurassic liopleurodon and other large pliosaurs stand no chance against a full pod of orcas, a mosasaur is barelly bigger than a bull orca and would be easy work, in the paleogene basilosaurus woudn't be that much of a threat, and even the largest buzzsaw sharks of the paleozoic would stand absolutely ZERO chance against a full pod of orcas

@@xanshen9011 Mammals already dominate sharks and pliosaurs/mosasaurs are far smaller than the largest aquatic mammalian carnivores (Livyatan Sperm whale Perucetus) and Basilosaurus is a about the size of the biggest mosasaurids).
One mammal I know would dominate the prehistoric sea is a family of orcas. Those things have a nice balance of intellect, size, and strength--being far smarter than any prehistoric sea creature that we know of.
Well of course it’s easy to exercise that when your one of the largest creatures to live on earth with the only animals that are bigger then u are whales
@Dr.Ian-Plect Orcas, unlike Ichthyosaurs, hunt and move in pods, and despite their considerably smaller size they are way faster and more agile. Orcas have been reported to hunt humpback whales and even blue whales, so preying on animals as big as Shonisaurus wouldn't be completely unlikely. Their superior speed, stamina, numbers and intelligence could overwhelm a single specimen of those Ichthyosaurs. The biggest problem for orcas would be the much warmer waters of the Triassic, since these animals seem to prefer colder environments.
5:10 I'm late to the party, so you probably won't respond, but smilodon lived in the tropics too, as North as Ceará and Maranhão here in Brazil. Even during the ice age 30°C+ would have been common in the summer. Today it makes almost 40 degrees here, and Smilodon also lived even closer to the equator. He living in subtropical South America in the triassic wouldn't be a problem, at least in my opinion. Look how Jaguars adapted to tropical south america too, also coming from the North. Megatherium though, lived only as far north as Rio Grande do Sul, so I can see heat being a problem, maybe if you selected Eremotherium, which also lived in Nordeste and Amazonas, then it could be the same argument as smilodon.
I was struggling to understand why anyone would say that a mammal like Hyaenodon Gigas was more closely related to "Penguins"(a bird) than it was to another mammal like a Hyaena. I had to go back and put on closed captions to see that you actually said "Pangolins" and not "Penguins" to realize that what I was hearing wasn't completely mad.
What would the hunting strategy be for the "smaller" ichthyosaurs on Perucetus? As far as their predatory prowess goes most of the evidence still suggests they targeted animals smaller than themselves and while not exactly well defended the conical teeth and thin snouts would probably have a hard time digging into a giant, round, fatty beast. And in terms of physical strength both sets of giants could do massive damage if they ever struck each other, though you're right the reptiles have an advantage due to their speed. A whack from the tail of a 90 ton sausage though would probably break some thing or multiple things in the reptiles. Also question: is each mammal also competing with each other or are they isolated scenarios? Spawning Livyatan on Perucetus for example drops the numbers even further but may also decrease ichthyosaur population since the sperm whale would be eating them too.
He grossly overrates ichthyosaurs in general. They all had relatively small mouths that couldn't open very wide and therefore could only hunt animals much smaller than themselves. Their conical teeth shows they mainly hunted smaller, fast moving fish. There were no macro marine predator that hunted other giant marine animals the way livyatan and megalodon did.
I would argue that predatory whales would have an enourmous advantage over reptilian predators based on the endurance. Long chase is the name of the game in the deep waters and mammalian endurance exceeds reptilian by miles(literally). Also the inteligence factor plays a huge role for predators with all modrlern mammals showing an upward trend in its growth.
When do you think your video about the biggest predator of all time will come out? It gives me the same vibes as Endgame did but in prehistory version. Oh and can you make a video speculating about how Megaraptorans could hunt? It’s one of the most underrated groups of theropods and they are very unique since they hunt with their hands which is something not seen in other groups of theropods expect maybe Spinosaurids.
We're hoping for February/March, but that's very tentative. It takes a while to hear back from researchers since there's so much going on! A megaraptoran video would be fun as well. I've been meaning to make one for a while and just need to find a time to put it in the queue!
I think the interesting thing about these large mammals is some of them were not used to dealing with predators around their size or were bigger than usual.
I feel like that Deodon would also survive in the Cretaceous Period maybe like it would probably kind of disguise itself like it’s my name its own business, and it would snatch a young triceratops.
This is presently one of my all time favourite videos. Oh, TH-cam Algorithm, raise up this grand content which subverts traditional Dinosaur V Mammal precepts! Praise be the Vividen!
This is fun, will see one of Mesozoic creatures in the Cenozoic? I would like to see how disruptive large predatorial Theropods would have been in the Cenozoic eras.
The Triassic was a free for all since Dinos didn’t have a stronghold yet. Bigger mammals would definitely fair better The Jurassic and Cretaceous on the other hand…..
One thing you forgot to consider is the atmosphere composition. While it wouldn't kill them outright like people tend to think it ours would giant Dinosaurs, it would at least be a hinderance during most of the triassic. The early and mid triassic oxygen low and generally high CO2 levels could give the large mammals a headache, literally and figuratively. They would be out of breath more quickly, lessening their primary advantages.
It was cool of you to rbing himalayasaurus into the discussion and compare it to Livyatan !!! The 3rd most dangerous macroraptorial predator in history against the 2nd !
Id recon Fasolasuchus could take on Megatherium, its no joke. Powerful bite, strong armour and huge size being 10 metres long, powerful claws too and decent intelligence. I think Fasolasuchus could handle the sloth if it could very likely take prosauropods.
Ya'know, this could be used to make a pretty cool spec-evo series. Though maybe add at least one or a few more cenozoic animals to the list, like Barinasuchus should DEFINITELY be one of them, maybe some other south american carnivores like sparassodonts and terror birds, perhaps even purusaurus. Could also be interesting to add marsupial predators like Thylacoleo, or perhaps New Zealand's famous giant eagle? Edit: if you're adding terror birds, then I HIGHLY recommend adding Kelenken to the list. Also, the giant shark megalodon. Edit #2: I have one more suggestion to make, add Basilosaurus to the list.
Considering how mammals alrrady have problems with overheating even in environments we're well adpated too, I think the difference between living in the ice age vs. the triassic would be a much bigger difference than stated and would especially knock down the giant Megatherium much further down especially. It takes time to adapt to that drasatic temperature difference of the environment, especially with the dense bodies of these thickly built animals like smilodon and megatherium. As an active hunter trying to take down armored prey that is much more active and mobile than any glyptodont, and bigger than any caiman while being almost constantly on the verge of overheating would be a big problem for Smilodon. They could die off just from overheating if the problem was too bad, although I doubt that last part. A giant, densley built megatherium the size of a large african elephant that may have already been hairless as a requirement even during the ice age would probably not survive an environment that much hotter as is.
Damn this is a great video! In the Triassic mammals seem to be doing very well! However, I have a feeling from here on out that is a trend thats going to fall off a very large cliff once we hit the Jurassic...
Twas my line that if you transport a viable population of house cats back into Jurassic times, in 5 million years you'd have a whole genus ranging from 150g insect eating kitties to pack hunting 500kg "lions" with everything inbetween and absolutely no carnivorous theropods left.
Animals like Lystrosaurus are Synapsids so they are more related to the mammals, even they layed eggs and hadn't fur. Synapsids and Sauropsids (Squamates, turtles, crocodils and dinos/birds) still split in the perm. So there were many relatives of mammals in the Triarassic, also some with the size of a hippo.
I'm guessing that the mammals aren't interacting with each other mammal sp, and large herbivores have empty guts so they aren't transporting plant seeds from their time. Anyway, love the spec eecology vids
modern mammalian herbivores might struggle in the triassic. Many mesozoic relict plant species are utterly unpalatable to modern mammals, especially ferns and cycads. Modern conifer lineages also hadn't evolved yet.
now i really wanna know how bears would do and specifically short faced bears and other large brown bear species. i would imagine that not many animals during that time would be able to do much against a short faced bear, but maybe to the smaller brown bears.
All animals mentioned lived in the same time so technically the animals surviving into the ice age would have survived if all of this was realistic and not evolutionary.
Smilodons could become larger in order to be too big & aggressive to be prayed upon. If it keeps it’s pack hunting tactics it might seriously become a worldwide apex predator like the Orca, but if it doesn’t, it would probably just become a unique apex predator.

Thank you! That's very gratifying to hear. I worked on the research for this episode for a long time, and I'm excited to eventually produce the rest of the series!
Idea for next vid
Thrive or Eaten Alive: The Early Jurassic (Dinosaurs vs Mammals)
I think the mammals will be less adapted to land as the Jurassic and Cretaceous arrive but in the seas they will thrive big time.
They had to deal with giant pliosaurs and mosasaurs along with sharks
@@xanshen9011 Mammals already dominate sharks and pliosaurs/mosasaurs are far smaller than the largest aquatic mammalian carnivores (Livyatan Sperm whale Perucetus) and Basilosaurus is a about the size of the biggest mosasaurids).
@@xanshen9011whales and orcas would destroy them
@@amrita_s8094 orcas would do a lot of damage big smart and hunt in packs they would even bully bigger animals
@@kilianteni7884lol megalodon is bigger
This was a great video! Lots of potential for spin-offs too with other animals in different times, cant wait for more!
One mammal I know would dominate the prehistoric sea is a family of orcas. Those things have a nice balance of intellect, size, and strength--being far smarter than any prehistoric sea creature that we know of.
One attribute could render them unable to establish a niche; superior size.
Well of course it’s easy to exercise that when your one of the largest creatures to live on earth with the only animals that are bigger then u are whales
@Dr.Ian-Plect Orcas, unlike Ichthyosaurs, hunt and move in pods, and despite their considerably smaller size they are way faster and more agile. Orcas have been reported to hunt humpback whales and even blue whales, so preying on animals as big as Shonisaurus wouldn't be completely unlikely. Their superior speed, stamina, numbers and intelligence could overwhelm a single specimen of those Ichthyosaurs. The biggest problem for orcas would be the much warmer waters of the Triassic, since these animals seem to prefer colder environments.
For real, we all know that Michael Jackson has the Spinosaurus Holotype though.
awsome video! one of my favorite topics but people usually do modern mammals. Im glad you're branching out!
I've always liked videos like these. I hope you will do it with other groups of animals and time periods.
I appreciate the effort of this video, there are massive holes in many of the depictions and behaviors of how much of these organisms would thrive.
Wow, this was fascinating.
Do one with extant mammals next, please!
Love this idea. Can't wait for you to mix and match other eras. Late Cretaceous animals in the Pliocene? or vice versa.
5:10 I'm late to the party, so you probably won't respond, but smilodon lived in the tropics too, as North as Ceará and Maranhão here in Brazil. Even during the ice age 30°C+ would have been common in the summer. Today it makes almost 40 degrees here, and Smilodon also lived even closer to the equator. He living in subtropical South America in the triassic wouldn't be a problem, at least in my opinion. Look how Jaguars adapted to tropical south america too, also coming from the North. Megatherium though, lived only as far north as Rio Grande do Sul, so I can see heat being a problem, maybe if you selected Eremotherium, which also lived in Nordeste and Amazonas, then it could be the same argument as smilodon.
Check out Vividen’s other speculative ecology videos. He’s awesome-bro content done right!
I was struggling to understand why anyone would say that a mammal like Hyaenodon Gigas was more closely related to "Penguins"(a bird) than it was to another mammal like a Hyaena. I had to go back and put on closed captions to see that you actually said "Pangolins" and not "Penguins" to realize that what I was hearing wasn't completely mad.
I can’t stop rewatching this vid for some reason. Love me some Triassic lore and spec evo stuff so this is great.
That Drip Goku caught me off-guard, not gonna lie. 😂
Same I was not expecting that to happen 😂😂😂😂😂
What would the hunting strategy be for the "smaller" ichthyosaurs on Perucetus? As far as their predatory prowess goes most of the evidence still suggests they targeted animals smaller than themselves and while not exactly well defended the conical teeth and thin snouts would probably have a hard time digging into a giant, round, fatty beast. And in terms of physical strength both sets of giants could do massive damage if they ever struck each other, though you're right the reptiles have an advantage due to their speed. A whack from the tail of a 90 ton sausage though would probably break some thing or multiple things in the reptiles.
Also question: is each mammal also competing with each other or are they isolated scenarios? Spawning Livyatan on Perucetus for example drops the numbers even further but may also decrease ichthyosaur population since the sperm whale would be eating them too.
Icthiosaurus will slice them but by bit doesn't kill them directly
These are isolated scenarios.
He grossly overrates ichthyosaurs in general. They all had relatively small mouths that couldn't open very wide and therefore could only hunt animals much smaller than themselves. Their conical teeth shows they mainly hunted smaller, fast moving fish. There were no macro marine predator that hunted other giant marine animals the way livyatan and megalodon did.
Cant wait for the jurassic one, great video!
I would argue that predatory whales would have an enourmous advantage over reptilian predators based on the endurance.
Long chase is the name of the game in the deep waters and mammalian endurance exceeds reptilian by miles(literally).
Also the inteligence factor plays a huge role for predators with all modrlern mammals showing an upward trend in its growth.
And how would u know that? Most marine reptiles were warm blooded at least in Jurassic-creatures
When do you think your video about the biggest predator of all time will come out? It gives me the same vibes as Endgame did but in prehistory version.
Oh and can you make a video speculating about how Megaraptorans could hunt? It’s one of the most underrated groups of theropods and they are very unique since they hunt with their hands which is something not seen in other groups of theropods expect maybe Spinosaurids.
We're hoping for February/March, but that's very tentative. It takes a while to hear back from researchers since there's so much going on! A megaraptoran video would be fun as well. I've been meaning to make one for a while and just need to find a time to put it in the queue!
I’d like to see what Paleozoic creatures would do good in the Cenozoic
I think the interesting thing about these large mammals is some of them were not used to dealing with predators around their size or were bigger than usual.
I love this video, please do more animals in the Triassic please
This was super entertaining, if you haven't already, I'd love to see the reverse of this.
Brilliant presentation! I'd love to see you put Thylacoleo in the mix in a future episode.
I like this type of video great job I can see all the hard work that went into this
I feel like that Deodon would also survive in the Cretaceous Period maybe like it would probably kind of disguise itself like it’s my name its own business, and it would snatch a young triceratops.
I love this. Would love more videos like this.
An extra point of consideration for Livyatan- they had sonar which is one of the most broken abilities that only mammals seem to get.
5:10 would like you all to suffer with me from the thought of a hairless Smilodon.
This is presently one of my all time favourite videos. Oh, TH-cam Algorithm, raise up this grand content which subverts traditional Dinosaur V Mammal precepts! Praise be the Vividen!
I'm looking forward to eventually continuing the series!
YOU FIND A FORMULA THERE!
DO
MORE
OF
THIS!!!
This is fun, will see one of Mesozoic creatures in the Cenozoic? I would like to see how disruptive large predatorial Theropods would have been in the Cenozoic eras.
This was fun, thanks.
You gotta do more vids like these
I'm planning on doing at least two more episodes for the Jurassic and Cretaceous periods!
10:15 Bruh it sounded like you said *Penguins* instead of Pangolins.
The Triassic was a free for all since Dinos didn’t have a stronghold yet. Bigger mammals would definitely fair better
The Jurassic and Cretaceous on the other hand…..
It's a shame racoons ate all your T-Rex eggs..
Yeah. That's exactly the animal to fuck up an entire ecosystem.
@@DzinkyDzinkmy dude talks like same sized mammals didn't exist at that time, t rex would do just fine.
One thing you forgot to consider is the atmosphere composition. While it wouldn't kill them outright like people tend to think it ours would giant Dinosaurs, it would at least be a hinderance during most of the triassic. The early and mid triassic oxygen low and generally high CO2 levels could give the large mammals a headache, literally and figuratively. They would be out of breath more quickly, lessening their primary advantages.
So glad you did this
92 minutes until the Premiere!
It was cool of you to rbing himalayasaurus into the discussion and compare it to Livyatan !!! The 3rd most dangerous macroraptorial predator in history against the 2nd !
make more of these for other periods
That's the plan!
Id recon Fasolasuchus could take on Megatherium, its no joke. Powerful bite, strong armour and huge size being 10 metres long, powerful claws too and decent intelligence. I think Fasolasuchus could handle the sloth if it could very likely take prosauropods.
Ya'know, this could be used to make a pretty cool spec-evo series. Though maybe add at least one or a few more cenozoic animals to the list, like Barinasuchus should DEFINITELY be one of them, maybe some other south american carnivores like sparassodonts and terror birds, perhaps even purusaurus. Could also be interesting to add marsupial predators like Thylacoleo, or perhaps New Zealand's famous giant eagle?
Edit: if you're adding terror birds, then I HIGHLY recommend adding Kelenken to the list. Also, the giant shark megalodon.
Edit #2: I have one more suggestion to make, add Basilosaurus to the list.
How did you do the weird life on earth thing
Considering how mammals alrrady have problems with overheating even in environments we're well adpated too, I think the difference between living in the ice age vs. the triassic would be a much bigger difference than stated and would especially knock down the giant Megatherium much further down especially. It takes time to adapt to that drasatic temperature difference of the environment, especially with the dense bodies of these thickly built animals like smilodon and megatherium. As an active hunter trying to take down armored prey that is much more active and mobile than any glyptodont, and bigger than any caiman while being almost constantly on the verge of overheating would be a big problem for Smilodon. They could die off just from overheating if the problem was too bad, although I doubt that last part. A giant, densley built megatherium the size of a large african elephant that may have already been hairless as a requirement even during the ice age would probably not survive an environment that much hotter as is.
"OHHH SHE SIZZLIN!" got me lol that's funny
Please make a Jurassic and Cretaceous video
Damn this is a great video! In the Triassic mammals seem to be doing very well! However, I have a feeling from here on out that is a trend thats going to fall off a very large cliff once we hit the Jurassic...
I want to see earlier human ancestors like Australopithecus Afarensis vs the Late Cretaceous.
This is a really Cool Idea!
Part 2 coming soon!
@TheVividen Do Megasauropod level members get informations on your new macropredator that surpasses Aust colossus?
They'll get to see the video 24 hours early when it comes out next year!
@@TheVividen And what if a Megasauropod members wants it this year as species profile video?
@@TheVividen Does the new macropredator surpass the higher estimates of aust 256t ?
@@kilianteni7884I suppose that'll be happening anyway haha. It's not ready yet, however--we're going for a release in March or later hopefully
@@kilianteni7884I wouldn't say that this particular specen is as big as the Aust Colossus, but it was designed for killing massive prey!
Intriguing video.
Skip ad 2:40
Thank the Lord that he doesn't put sponsors in between the videos.
Awesome content
Please make could Cenozoic megafauna survive in the creatasous and please add the large marsupial from Australia
Great concept
Twas my line that if you transport a viable population of house cats back into Jurassic times, in 5 million years you'd have a whole genus ranging from 150g insect eating kitties to pack hunting 500kg "lions" with everything inbetween and absolutely no carnivorous theropods left.
Animals like Lystrosaurus are Synapsids so they are more related to the mammals, even they layed eggs and hadn't fur. Synapsids and Sauropsids (Squamates, turtles, crocodils and dinos/birds) still split in the perm.
So there were many relatives of mammals in the Triarassic, also some with the size of a hippo.
Could you do this but with tyrannosaurus in the triassic, jurassic, and cenezoic.
I'm guessing that the mammals aren't interacting with each other mammal sp, and large herbivores have empty guts so they aren't transporting plant seeds from their time. Anyway, love the spec eecology vids
Video Idea: Could Early Cenozoic Mammals Survive the Mesozoic? The Jurassic Period
modern mammalian herbivores might struggle in the triassic. Many mesozoic relict plant species are utterly unpalatable to modern mammals, especially ferns and cycads. Modern conifer lineages also hadn't evolved yet.
Great video!
Do jurrasic next
now i really wanna know how bears would do and specifically short faced bears and other large brown bear species. i would imagine that not many animals during that time would be able to do much against a short faced bear, but maybe to the smaller brown bears.
All animals mentioned lived in the same time so technically the animals surviving into the ice age would have survived if all of this was realistic and not evolutionary.
Jurassic and Cretaceous videos also planned?
The Jurassic episode is in the works!
Oh, this is really good facts are usually hear Livyatin whale pronounced like Liviathan
I suspect many of the large mammals would gravitate towards water which they could use as a heat sink to prevent overheating
Smilodon vs Triassic crocs: Bite they're long necks.
Jesus! Are the size estimates of The Aust Collossus accurate?
i think throwing them in the triassic is an act of mercy 💀
If you do this again make sure to include some human species
Vivden，I heard there's some information out there about Bertha. What's going on?😮😮
You probably know about as much as I do for now, unfortunately--the only thing I've heard is that she might be bigger than Cope.
@@TheVividen Wow, it must be big news.
I'm hoping that the paper comes out before the end of the year!
@@TheVividen me too.
Meglaceros's habitat stretched a long way. It didn't live in a lot of different habitats.
Smilodons could become larger in order to be too big & aggressive to be prayed upon. If it keeps it’s pack hunting tactics it might seriously become a worldwide apex predator like the Orca, but if it doesn’t, it would probably just become a unique apex predator.
You showed and mentioned lobsters for perucetus when lobsters didn't exist until the cretaceous
