Could giant mammals survive in the Jurassic Period? The macropredatory whale Livyatan and the other mammalian all-stars of the Cenozoic are dropped into the Jurassic Period, and we analyze how they'd survive. This speculative ecology video analyzes ten giant mammals and their diets, sizes, competitors, and threats if they were placed in the Jurassic Period. Smilodon, Megatherium, Livyatan, and others are ranked on a scale of 1 to 10 based on how they would adapt to their new ecosystem and reptilian rivals. Will these mammals thrive...or be eaten alive?

At least ancient humans hunted other things; Saurophaganax would probably take them out even more rapidly.

I just wanted to say thank you so much for making this series based off my question it's been so cool to see how many of my favourite prehistoric mammals would fare in the Mesozoic! The Cretaceous episode can't come soon enough! :) Another invasive species idea I had alongside the roster we've seen is the terror bird Kelenken I wonder if it could survive alongside the likes of Giganotosaurus, Mapusaurus, Meraxes and giant Titanosaur sauropods in South America? Carnotaurus too. I imagine Kelenken could make some sort of niche for itself although I do think the Smilodon and Megatherium might have some trouble in the Cretaceous of South America!

A comment about Paraceratherium is that since the landmasses of the cenozoic and jurassic were very different, the distribution can't be hyper-specific. If it were moved to its general area equivalent of the Jurassic, the fossil record shows for example signs of giant Megalosaurids like Torvosaurus as far east as Germany, which was very close to where Paraceratherium would have lived in Europe, and in China where they also lived, there was Yangchuanosaurus, that could grow up to 11 meters. It is very likely I think that Paraceratherium may have shared a habitat with large theropods perhaps around 8-11 meters long, certainly big enough to actively prey on even some adults and certainly sub-adults, and assuming their real life experience would apply, being hunted by predators many many times the size of the ones they were accustomed to would present a novel challenge for them. And since size is their only protection, I'd rate them lower. Similar sort of deal applies for basically all elephant relatives. Tusks would be no novelty to the giant predators of the time, who also had to deal with thagomizers. Even an animal like Paleoloxodon Namadicus (and preface here, the largest estimates for the animal are based basically nothing, fragmentary bones from hundreds of years ago, now disintegrated, so it wouldn't likely have been bigger than Paraceratherium) would have been seriously threatened by megatheropods.

I know it's not a giant mammal, based on the others in these videos, but I'd like to see Orcinus citoniensis transported to the Cretaceous. I think they'd very easily fill the vacant niche that was previously occupied by Ichthyosaurs, while possibly evolving into a similar species to their current day cousins. They could even halt the arrival of Mosasaurids into marine ecosystems, possibly.

And it did not disappoint 😁 I was interested to see the Stegotetrabelodon doing well with the vegetation and predators better than my poor Columbian mammoth 😭 Smilodon doing well was nice to see! I can't wait for the final Cretaceous episode in the future! I do think if there could be another additional invasive species the giant short faced bear specifically Arctodus or Arctotherium could be cool to see in the Cretaceous. Paraceratherium living alongside Therizinosaurus, Deinocheirus and Tarbosaurus would be awesome!!

Theropoda have hollow bones and are highly muscularized, like modern birds, thus they're very agile, like modern birds. Predators like allosaurus adapted for tens of millions of years to hunt giants like stegosaurus [as big as todays biggest elephants] which adapted giant serrated spikes covered in keratin across its back, and a massive tail with spikes at the end and massive muscle attachment joints. These animals spent tens of millions of years honing in biomechanically to deal with giant predators/prey with specialized armor and weaponry. But a slow mammal with primitive lungs, primitive bones and 2 buck teeth is a threat? A slow fat mammal whos biggest threat was a cat that's a few hundred pounds? LOL

​@@trvth1sYou are heavily underestimating proboscideans. "Slow fat mammal" as an elephant enyojer I feel offended. Elephant's body fat is literally lower than in athletic humans, and it was likely pretty similar in columbian mammoths. Elephant's trunk has more muscle than entire human body. They are also smart and know how to use their weight and tusks. A theropod of smaller/close size is going to have a hard time killing an adult M. columbi, not only because it's smaller, but also because mammoth's skin is quite hard to pierce, and it can also kick or just use it's massive tusks like a club. Also, no predator other than human was dangerous for adult M. columbi. I love dinosaurs. I love mammals. I love animals in general, but I hate when someone is downplaying one animal group and praising another.

@330 I agree with you. I'll add: ornithischian dinosaurs were very similar to mammals: their bones were full of marrow, they chewed their greens. They had a few differences [teeth never stopped growing] but nothing too crazy. Their highest weight limits were also the same as mammals. Ornithischians thrived, so mammals could theoretically. The issue i see is that ornithischians were in an arms race with giant predatory theropoda for tens of millions of years, so even though they were as big and strong as mammalian herbivores, they adapted features to deal with giant predators. The giant predators were possible because there was a lot more big prey. Look at hell creek formation. You had 2 ceratopcian species bigger than any terrestrial mammal today. You had an ankylosaur which was as large as bush elephants, and another ankylosaurid species as large as asian elephants. You also had bush elephant sized edmontosaurus which were in massive herds. The icing on the cake, you had a whale sized titanosaur, which when dead would provide plenty of calories for scavenging predators. My point is in many habitats elephants were not too large to take out. The 2 ceratopcian species in hells creek that were bigger than bush elephants, had to evolve a massive thick serrated frill covered in keratin just survive predatory attacks, these are characteristics mammals like elephants havent had to evolve. Throwing a modern elephant who's the best of this age in an era where it would be less than average would be suicidal. I do agree allosaurus would have an issue with colombian mammoth but i think it would do perfect against modern bush elephants. Allosaurus is not the largest theropod even of its time, there were habitats where colombian mammoth would be out of its depth

The thing with elephants in particular i think people over estimate them alot. Elephants tend to go extinct relatively quickly when there is a Predator that can reliably hunt them in most biota due too slow population replacement compared to say a pig that is half their size. Their size is their biggest advantage and having that taken away makes them very vulnerable. Id argue that smaller mammals can survive better as they are competiting in niches they can outpace dinosaurs in.

Adding to my comment it seems like alot of paleo circles are propping up elephants along with orcas and humans as thriving in mesozoic animals. Orcas probably have the best chance of the three. With humans, anything below erectus on intelligence is not gonna expand at all and as for humans themselves it depends on part of the mesozoic, like our expansion may be slowed or accelerated. While elephants would actually suffer more than other animals like pigs and small fast antelope as there are predators that can reliably hunt them down while being hilariously outpaced in reproduction by the native herbivores. It seems like the idea kinda sprouted from a gojicenter video. Where people have concluded that survival of a species depended on winning 1v1 fights against suicidal predators. Which If that's the case buddy. Cows would've wiped humans out long time ago.

Not just that, but during the jurrassic megafauna had been in an arms race with giant predatory theropoda for tens of millions of years. For example: stegosaurus was elephant sized yet evolved sharp serrated plates covered in keratin and spikes hooked to a highly muscularized tail with massive muscle attachment sockets, this to deal with the giant predatory theropoda. Many theropoda were also specialized at taking out giants. Giant mammals never had to deal with this, they never had to deal with giant predators, bush elephants of today do fine solely based off their mass. By the jurrassic elephant size megafauna still needed extreme armor and weaponry to survive. Sauropoda, which relied on mass to avoid predators like elephants now, were already beyond the limits of mammalian bones.

Something i think you underestimated here is the Columbian Mammoth's intelligence. If they were as smart as their relatives today they'd surely find ways to defend themselves from large predators. Perhaps having Bull males around the herd instead of them being nomadic and solitary.

Jaguars hunt 100lbs fish eating caiman, nile crocodiles would crush them literally. Sauropoda are FAR too thick, too powerful. The smallest sauropoda ever is FAR bigger and FAR more powerful than anything jaguars hunt, but with an ambush i do brlrive jaguars could kill them likely by chocking. If the tiny sauropoda saw the jaguar it would put up a good fight and possibly crush the jaguar. The tiny sauropoda lived in an island, island dwarfism. No mammal in history would be able to kill the medium sized or large sauropoda on land unless said mammal had human made weapons.

I was excited to see Livyatan dominate the oceans of the Jurassic I'm surprised not even the giant Pliosaurs could be much of a problem for it, makes me wonder how Livyatan would fare in the Cretaceous? I was a bit sad about my Columbian mammoth getting annihilated by Saurophagonax although they do have large tusks I think would be helpful alongside their social herding behaviour. Perhaps in this scenario they'd stick with some herbivorous dinosaur species of some sort for mutual protection?

I dont think so, saurophanax likely hunted sauropoda that were far larger and far more powerful than colombian mammoth. If the colombian mammoth is alone it is an easy meal, like the video of the moose on musk that fought a brown bear and became dinner. Colombian mammoth never had to deal with giant predators. Stegosaurus was elephant size and it was specially adapted to deal with giant predators thus why its entire body is a weapon.

i feel like you really downplay the colombian mammoth here, 1 saurophagonax or torvosaurus would have a hard time taking on even one mammoth. even losing to one most likely. you also have to take in account that mammoths would likely travel in big herds which would grant them alot of protection.
@spideyfanw1748
@spideyfanw1748 10 ай бұрын
Saurophagonax would most likely try to kill the Mammoth through blood loss by using its huge claws and teeth. As for Torvosaurus, its bite force would be more than enough to break off the Mammoth’s tusks or break any bone in its body along with blood loss from is huge claws. The Mammoth doesn’t have huge armor or thick reptilian scales/skin to protect itself from the damage their claws would cause. Also Elephants today can defend themselves easily from the front but they’re vulnerable from behind and that’s where lions, hyenas and other predators that can hunt young elephants attack them when ambushing them. These two theropods would have no problem ambushing a lone full grown mammoth from behind, doing as much damage as possible before backing off. Then they would just repeat the process until the mammoth died.
@hyrax2330

@@spideyfanw1748 The tusks, maybe if it can catch a good grip and mammoth won't move much. That's because tusks are made of dentin and enamel, not just bone. Mammoth might not have armor, but the skin would be pretty good against strong bite forces, because it was thick and loose, like in modern elephants, so it can absorb shock in thicker areas. Also mammoths could kick with one back leg at a time (like modern elephants), which might not be effective against predators of similar size, but against smaller torvosaurus and allosaurus it could do some damage. A pack of torvosaurus, or bigger sized predators would be very dangerous for a lone mammoth, but one predator, even of similar size, wouldn't have it easy by any means.

The Jurassic with it's Gigantic Hell Chickens (Chickens ARE Dinosaurs), seems impregnable from later mammalian predators, but that's wrong, very large animals was only a small part of the total population. There is Not a Theropod in the fossil record that could catch even the slowest of today's big cats in a dead run. I can seriously visualize because I have studied Jaguars (3rd largest cat) a long time, they would run rampant through an unsuspecting Jungle (*), with large enough population I can visualize local extinctions of both prey and that prey's previous predator. (*) imagine your favorite Sweety of a Furball Mouse destroying Kitty let loose after hours in a pet store with many open top containers, so Many mouse variations it makes Miss Kitty from Kansas City head shake, there's occasional snakes, large lizards w/ of course always a few Counter Butt-smelling Canines to pose potential hazards but a Wiley cat can get around all that non-sense. A Jaguar, after thinking about it more, would have destroyed most of the early Jurassic's jungle inhabitants. There vids of Jag's attacking and defeating Black Caimans larger than themselves IN the Water (the water is where today's Crocodilians Usually has All the Advantage).
