have large batches of offspring relatively frequently would somewhat diminish humans ability to hunt them to extinction. (This is a reupload due to audio issues in the first upload)
as far as we know allosaurus lacked feathers at all like modern birds if it had any, so it couldn't make a nest and sit on it's eggs like a modern bird, more likely it buried it's eggs or built vegetation mounds like many modern reptiles and some birds, so it's eggs wouldn't necessarily be predated more heavily that modern reptiles, their eggs larger size might make them more of a target, but would also protect them from many smaller predators.
There eggs would probably be closer to the size of the rodent itself, but definitely theres no denying that there would be predation on their eggs, i just think it wouldn't be disproportionate to modern reptiles and as such wouldn't be too detrimental, allosaurus most definitely dealt with egg eaters back in it's day too
@@Sedimented.Studios since we are speaking about reproduction problems there is one quirk of large theropods that i never see mentioned when talking about scenarios like this that i think would be their Achilles heel. In most ecosystems in the fossil record where large theropods are present we see only small carnivores and big carnivores with no mid tier carnivores present. Thats because the large theropods young serve as the mid tier carnivores in those ecosystems. so here is the problem: In the modern day the niche of mid tier carnivore is already filled. not only that but the niche is mostly filled by highly intelligent pack predators! Any young theropod would probably get curb stomped as soon as they left their parents care.
@@Zavult Thats a gross generalization. In fact no midsize predators is more of an exception, mainly in the cretacioous north where tyrannosaurs evolved from nimble juvebniles to larger megacarnivores.. For example, for over 40 million years the general dynamic was carnosaurs being the biggest while ceratosaurs being mid size. Then in the south abelisaurs were mid size, ranging between 5-8m, while megaraptorans became the largest predators.Other mid size predator examples: convanenator, neovenator, utahraptor, moros, alioramus, allosaurus itself.
I gotta disagree on lions going extinct, they'd just shift to favor zebra and wildebeast. And I'm fairly sure a herd of cape buffalo would very quickly learn to mob and gore young allosaur to death as an instinct, like they do with lions already.
Allosaurus were theropoda so there was certainly parental care, maybe even from 2 parent. If buffaloes tried to gore then young massive parents would be there to kill them. We also cant forget that allosaurus were egg layers, they laid many eggs so their gestation period was far more competitive than lions and other mammals. If a baby got killed theid have many more on the way.
@@66Traveler99 They don't hatch at 3 tons dude. And it's never going to get to 3 tons if it gets stomped into paste while it's only 200 lbs. Which is what *I* was saying.
@@trvth1s Doubtful the parents would keep a 10-pack of hatchlings once they were over a size limit. Ostriches would be good stand-ins for the behavior you're talking about. But a juvie pack is more likely than a multi-age adult/subadult/juvie mixed pack. Just in terms of what they would need to eat.
@@Stothehighest it's hard to say. Trex is the most studied extinct species ever, we know that they had a massive growth spurt until they got to about 2 tons in which point growth continues but slowly. They were likely cared by 2 parents until at that age they were very fast and massive powerful predators so maybe parents abandoned them at that age since theid be self sufficient and filling a different niche from adults. I'm sure allosaurus had a similar path. Oarents cared for young, fast growth until they were large enough to protect themselves and hunt.
I'm afraid there is no doubt that if Allosaurus had made it to the modern day that it would have become a prime target for trophy hunters and poachers. Poachers may have killed it for depleting the supply of elephants with their valuable ivory. Not sure if Allosaurus teeth would have attained anything near the value of ivory.
That is a big definite but specifically those poachers who want something that can fight back as Elephants are certainly those who want zero smoke, though humans are humans who bring smoke for no reason.
@@lildragon6415 If we hunted mamoths to extinction using spears, allosaurus would be no problem. Honestly big cats would be more dangerous because they're smaller, harder to hit, much better at ambushing and are more agile. Sticking a spear in a big 2 ton animal is much eaiser.
I'd be interested if a spinosaurid could survive in todays habitats. I could see baryonyx surviving in the amazon, or suchomimus stalking the shallow waters of rivers.
Amazon basin, mekong river and Borneo have some truly huge freshwater species. Some very similar of those that Baryonix could've eaten during it's time.
One thing to note, is that poachers, which are common in the Savannah, would probably see Allosaurus as a new source of income, and start hunting them. Because they reproduce fairly quickly, this would not be as devastating to them as it is for other large animals. But it would still likely be one of their most common causes of death.
@@hoaxes8537 Not just that, These animals are unpredictable. If a tourist would wander around to see, these theropods would immediately think that they're poachers. Also, who knows, we do not know how smart these things are, but we do know that Dinosaurs, particularly Theropods are warm blooded. Let that sink in, they might hunt not on the day, but always at night when the poachers are either resting or hunting the same time. They're not like the Elephants that knew they have to run, not like the Rhinos that they would blindly attack. These animals are just as capable as a hunter, well it depends on the terrain since they're massive by size. They might choose a rocky, forest, tall grass anything that they can take cover. Also they have a pack behavior, a very social one like Prides of Lions. They might have an alpha that is smart enough to counter poachers or rather to counter the ones who hold rifles (but i might be stretching it), not to the extent that they would think like a human by mind, but expect something when they manage to survive a poaching event of their lives. And let them learn from that experience. What we do know that they, as well could potentially more dangerous than poachers. They would hunt not just the poaching teams but everyone, any humanoid shaped person, that is living and breathing. Like how lions kill a cheetah cubs or like how Male bears kill a bear cub of from its fallen mate to have its female. The entire Allosaurus would see us as their 'enemy' not rival, not prey, but something that they would eradicate for the safety of their chicks. Well at least what i would think so, if they have a cognition similar to birds and other similar animals of behavior.
@@assaulthetz the thing is there not smarter than a human nothing atleast that we know about on this earth is smarter than a human if they pose an actual threat night or day ambush or not poeple will kill them doesn't matter if they are a poacher or not claws and teeth are not stronger than an gun them hunting in groups will not matter because guns exist the more realistic thing is instead of them "hunting humans" they'll more likely run away or hide.
Keep in mind that juvenile allosaurus would need to reach adulthood in an environment where many other large and successful predators hunt in packs and their young get to freeload their way to adulthood. Allosaurus may have had parental care but this likely didn't include complete food provisioning and young would likely be hunting for themselves. Given they are slower than most other African predators, the risk of the young becoming prey is probably a serious concern.
They also had to deal with predators when they were alive. The allosaurus babies were fine. Most will die before adulthood, as is the case with modern predators.
I'd love to see more videos about what would hypothetically happen if a prehistoric animal was in a modern day environment. Like what if Utahraptors lived in the forests of Northwestern U.S? What if Mosasaurus swam the waters of the Pacific? What if Hatzegopteryx soared through the skies of today?
@@Themountain6197 I don't think they'd compete with bears that much, since bears are omnivorous and can get by eating anything they want, while it's arguably more difficult for Utahraptor since they're obligate carnivores that need to hunt. Bears can also run much further than Utahraptor. Studies show Dromaeosaurs, despite their name, aren't that suited for running long distances. So Utahraptor would most likely be an ambush hunter, kinda like a big cat.
@@jacobcox4565only time they’ll clash is if they stumble across one another winter and baby’s utar eggs will probably be one of the best snacks for a bear or other animals
@@jacobcox4565 bears can't run, they do so in short bursts. A freaking theropod is gonna easily outrun a bear. The only valid point u got is that bears are omnivores. That still won't leave them out of a raptors bellies tho a bear wouldn't last long against a Utahraptors kick which can leave slashes 6 feet long and a foot wide at it's peak. A Utahraptor would literally gut a bear EASILY
Lions would do fine in this scenario since they rarely or almost never hunt adult rhinos, hippos and elephants. A giant predator like allosaurus would just hunt the big guys of the African continent while lion will continue to hunt their usual prey added with the allosaurus bullying from time to time🤔 Honestly it would be a balanced echo system and adult elephants can finally have something to fear for other then humans finely 😂
Good point. Honestly, i believe rhinos would have the hardest time dealing with allosaurus. Rhino eye sight is poor, allosaurus could take them on at night, theid clinch on like an eagle but with their massive claws, and start bitting slicing flesh while the rhino struggles and eventually tires. Rhinos, like all large mammals, have a long gestation period, and the only thing they could maybe do is run away. Girraffes are a lot faster, hippos can get in the water, elephants can fight back but rhinos can MAYBE run away.
Yup, a two ton predator with razor blades for teeth that preys on tanks with spiked tails and 40+ton long necks is no match for a 7 tone elephant gotchia lol.@@hugomas5207
Lions also only hunt in the mid day or night, so there would be time if an Allosaurs hunted their prey when they slept. We know this, because Cheetahs tend to hunt at different times of day to avoid Lions.
My favorite dinosaur was pretty good at coexisting with other theropods in the Jurassic, so I'm quite sure that leopards and hyenas might coexist with it quite well due to niche partitioning. Additionally, the size difference between lions and Allosaurus would be severe enough to consider their niches as separate ones, as lions could hunt smaller prey while Allosaurus would be limited to the largest animals.
Allosaurus would also practice kleptoparasitism, taking lion and hyena food at will. I beleive an issue would also be large mammals sustaining enough healthy population numbers to support a super predatory theropoda. Allosaurus hunted in a time where megafauna had a far more competitive gestation period than todays mammals.
You seem to think that the Allosaurus would actually stay the size it was. Due to the scarcity of large prey animals it would shrink to make sure there would be enough food. Dinosaurs have done this in the past and have shown that it really doesn't take long.
@Niggass1255Probably not now that I read ops comment. Dwarfism is extremely common among large creatures in areas with little food, and it doesn't take long at all. Allosaurus would probably shrink
Allosaurus is definitely an interesting predator for the Savannah, it's a powerful animal while being more flexible than its megatherapod counterparts. As for other dinosaurs to introduce, Tyrannosaurus for doesn't have the speed to outright catch most of the prey items in the Savannah, but it does seem to be more of an endurance hunter. It also has a lot of soft factors like large eyes and padded feet. Still, it wouldn't have had the concealment it had in the swampy Hell Creek formation. Predators that intrests me more in this regard are carnivores like Ceratosaurus, Carnotaurous, Dilophosaurus, Azardarkids, or the moderate size Tyrannosaurs like Albertosaurus or Nanuqsaurus.
definitely, while everyone want to think about tyrannosaurus being introduced into the modern day, it probably wouldn't have enough prey, and even african elephants would stand little chance against it, so it would be a pretty simple dynamic
Disagree. A T-Rex dumped in modern savannahs (with no human interferferance), would still die out pretty quickly. Most smaller mamals would prey on and destroy T-Rex eggs and decimate any future generation. Mamals, lizards, and birds would kill of the majority of and eggs, regardless of the number of eggs they lay. Any young T-Rex would also be fair game for many of today's predators. Pack animals would out number and kill any young offspring. Very few would ever reach maturity. And eventually would not be repopulate fast enough to sustain the species and would die of once again. Also you underestimate Elephants. Elephants are a lot smarter than dinosaurs, and 8f a female was attacked by a T-Rex or Allosaur the dominant male and younger males would charge it. And as dinosaurs are massive they have a greater surface area to get hit. An enraged Bull Elephants tusks can still puncture a dinosaurs hide. And seeing as it would only need to be stabbed a few times to bleed out and die it would not kill as much as you think it would.
@@craiggibbons8228 I disagree with you completely. 1.Trex were theropoda, they likely took turns caring for eggs like modern birds that pair. Trex would also care for its young to some extent just like all archosaurs. Mammals wouldnt be given a chance to get the eggs. Ostrich lay eggs in Africa and plenty of mammal predators can outpower and kill their young, ostrich are ratites. Trex layed more eggs and no modern mammal would dare take its eggs, trex also had phenomenal eye sight and olfactory so no mammal could possibly sneak at night and take an egg. Also: trex cared for their young. Trex young also had a very fast growth spurt, by the time they were 2 tons in mass they were far deadlier than lions and just as agile, trex slowed down when they bulked later in life. 2. Elephants are small triceratops. Triceratops could reach a monstrous 13 tons in mass, they also had solid bone horns covered in keratin[ far more powerful than elephant tusk. Triceratops, with all of this astounding power and weaponry, still had to evolve a thick solid bone frill covered in keratin with sharpened edges in order to protect its neck from trex. Elephants wouldnt stand a chance. Triceratops were far bigger, far stronger than elephants and had far better biomechanical defenses, and they too were herd animals. If trex could handle triceratops [big target still] elephants would stand 0 chance. Elephants evolved to deal with 300lbs predators like lions, not 12 ton super predatory theropoda.
@@trvth1sTriceratops probably wouldnt protect another triceratops, they would Just get away asap to avoid injury, but elephants actually do protect eachother, thanks to their superior intelligence, so the best choice for T.rex would be to ambush solitary bull, which would still be pretty dangerous since and elephant tusk would be able to pierce T.rex's hide.
@@trvth1sAlso the largest Triceratops was around 8.5 Tons, so the average triceratops would Weight around 6 Tons, not THAT big of a difference in weight
The main problem for Dinosaurs in the modern age is that modern prey animals have adapted speed instead of size as main defense against predators. Scavenging from other predators rely on them allowing it to happen as it's quite likely that modern predators will learn to move elsewhere if they smell an Allosaurus being in the area and that would leave it to rely on itself for hunting again leading to eventual starvation. Taking on the larger and slower animals like Elephants and Rhinos comes with the real risk of injury making future hunts even harder, even if that fight is won. I think the big land crocodilians would fare better as they don't need to eat as often so could both survive longer on scavenging and need to successfully hunt less often. Pterosaurs being strategically mobile would also do well, even if the giant ones would suffer from us humans not liking things that puts us on the menu.
Ye theres a very big reason the most successful predators right now on land are canines and felids. They have speed and strength with very adapted ways of killing efficiently. Being big as a predator isn't really helpful anymore given theres nothing big enough for them to really take on easily.
Your comment is ignorant of ancient fauna. There were always fast herbivores during the age of dinosaurs, that is not a new strategy. Gallalimimus, which lived along side Trex, could run over 65mph, and it was a theropoda so it could sustain that speed for far longer than any mammal in history thanks to its airsacs. Juvenile trex were extremely fast and explosive, they likely hunted these herbivores. Nocturnal predators like dakota raptor may have also hunted them. Most theropoda were stamina hunters thanks to their airsacs, but the giants were built to go after other giants. Trex is the result of giant theropoda hunting giant prey for tens of millions of years, there is no mammal equivalent, mammalian herbivores would be no match as they never had to deal with predators bigger than 1 ton in most cases. Hunting large prey was ALWAYS a risk, more so in the age of dinosaurs because the prey adapted not only size but armor and weaponry to deal with giant predators, like triceratops giant thick frill, giant horns, etc. Also, egg thieve mammals and snakes existed in the age of dinosaurs. It almost sounds like you think only the big dinosaurs existed in the cretaceous, the small animals were there as well
@@trvth1s Gallimimus was not cheetah level fast, all the most recent data-driven studies put Gallimimus at 30-40 mph max, about as fast as a modern lion at top speed. Very fast for a non-avian dinosaur, but nowhere near 65 fucking miles an hour. You're still stuck in the 90s, your view of dinos is outdated.
@@trvth1s that study was highly dubious cause the method used was highly questionable and not trusted by most scientist, the same method was used on footprints on ancient human tracks in Australia dated to 20k years ago, it produced an estimated of 30 mph. Now do you really think a fucking aboriginal from tens of thousands of years ago can outrun Usain Bolt?
I feel like they would absolutely terrorize Nile Crocodiles. A full grown Nile can get up to 1700 pounds. Just imagine one sunning itself and getting ambushed before its slow ass could get into the water. It would be like Jaguars hunting caimans in South America.
Jaguars hunt caimans that are considerably smaller than itself. A fully grown Nile croc is still very large and has very strong armor and bite strength. Also predators don't generally take on animals where they can get hurt a lot. One bite to the allosaurus's leg and its over for it even if it kills the croc.
@@taranpreetsingh2347My money is still on the Allo. It would still dwarf the croc, even a full size one. And they have longer necks with more range of motion. A croc keeps it's back to the water to hide their tail, but an Allo could likely just reach around it and snag it up by the tail
If Allosaurus was somehow brought into modern day. Whether or not it gets to continue to exist would be entirely up to us. As such a large predator that could roam anywhere and unlikely to be scared off as easily as most mammalian predators it would be gone within a month of discovery.
That is because of MAN, the worst thing on this earth, who kills indescribably whatsoever he wants to do, thus any poor Allosaurus would be a prime target for man to hunt and murder 😢
I think large theropod dinosaurs would just starve to death in a modern ecosystem to be honest. Modern megafauna is too rare, too fast and too intelligent for them to get enough food. Even if they could hunt them successfully, elephants couldn't survive their hunting pressures. They would starve to death after overhunting their food supply.
Allosaurus lived during a time of higher oxygen levels in the air. If it was brought to the modern day environment, it would soon die of oxygen shortage, similar to altitude sickness.
Another interesting idea would be to introduce Allosaurus fragilis to early Miocene South America where it would compete with the similarly sized Barinasuchus, I'd also suggest adding other non-avian dino species as well, such as Velociraptor and Deinonychus, ankylosaurs, hadrosaurs, and titanosaurs, that way you could basically recreate the Age of Dinosaurs in miniature in Miocene South America. These reintroduced dinos would not only impact Miocene South American ecosystems, but potentially have even wider impacts on the global climate as well due to the sudden influx of green house gas emissions they'd give off. Which could then in turn lead to so many more impacts across the globe. Honestly, it could make for an AWESOME spec-evo project/series, I'm actually a bit disappointed that no one has seemingly done this before.
Another interesting thing to explore in such a scenario is, assuming there is no localized mass extinction of South American fauna like in OTL, then you could explore the faunal interchange between North & South America in this ATL, you could explore how non-avian dinosaurs colonizing North America affect the mammal dominated ecosystems therein, and explore how the dinos evolve in turn as they colonize further north towards the arctic and the Bering Land Bridge and eventually begin colonizing Eurasia.
You mentioned it would make a good spec-evo project and it definitely would, theres a spec evo project called "Tales of Kaimere" if you haven't heard of it that mixes dinosaur descendants and modern animals, although it takes place on another planet and has some "magical" shenanigans.
Miocene South America was already dominated by a bunch of predatory clades. Sparassodonts, phorusrhacids, and sebecids come to mind. Whether this would help or hinder them is the important question…
Loved the video. Would have liked to see images like the one with the human for scale showing size comparison between allosaurus and the African mammals mentioned.
I also think that allosaurus chicks would struggle to grow into adults with the constant pressure from smaller mammalian carnivores as well as monitor lizards and pythons. Jackals, hyenas, leopards, and cheetahs could easily hunt and kill small chicks and easily outrun an angry allosaurus mother hence possibly keeping the population of allosaurus very small to only a few thousand. After a few million years you may see a trend where Allosaurus begins to speciate into being smaller so they can prey upon the more faster and agile mammalian herbivores kinda like how terror birds did filling the niche of the now extinct lions, and also having a species that is typically larger in size to better hunt elephants and other larger megafauna.
@GabiteEditz it didn't live with the Tyrannosaurus Rex. By the time Rexxie came along big AL was long gone. If it did exist alongside the T Rex it would most likely adopted territory as not to go head to head with the Tyrannosaurus.
You're underrated the stealth of allosaurus. Elephants are notorious for appearing disappearing. They are extremely quiet, allosaurus like elephants had big padded feet. So it was probably a pretty stealthy boi.
This is an exteremly naive video with inaccurate knowlege of the mammals and exaggerting dino bias. Firstly, allosaurus can't survive in today's atomphereic pressure or the weather conditions. If they hypothetically did. Their lack of speed and bipedalism will prevent them from hunting megafauna. Rhino and hippos are also 2 tons and their hide can't be penetrated by slicing teeth of allosaurs. Rhino and hippo can also do substancial damage to the theropod. They have no chance against adult elephants. Lions and hyenas are group hunters and they are smart mammalian predators who are best at exploiting weakness. They will be fearful and cautious initially but eventually they'll outcompete the dino by killing their young and ganging up on solo adults. How much allosaurs laid eggs is unknown, and their eggs will be targetted by not just big cats but also baboons, warthogs, honey badgers, jackals etc. Unlike crocs and monitors, they did't even have hidden nests in secret places. The reality is, even without human intervention, and ignoring the physics and anatomical factors, if allosaurs are introduced in Africa, they would go extinct within a couple of years at best. Reality is often dusappointing. It's not a fantasy sci-fy, so wake up. Now I know that the admin of this channel has very limited knowledge and not a reliable source.
but wait, are you saying just a single allosaurus or multiple allosaurus? also, will it have subspecies? for E.G : A. (A. Is allosaurus) A. Fragilis A. Maximus A. Jimmadseni sorry for asking too much
This is a pretty interesting video. I wish there were more people making these kinds of videos where dinosaurs are brought into the modern world and the impacts it would have are brought up.
It is hard to compare an allosauruses predatory capabilities against modern mammals by using weight. Allosauruses bones were hollow, making it much lighter than any mammal of similar size, but that does not reflect its muscle mass/strength ratio in comparison to weight. I think they would be much more lethal than most people realize.
@@gamesguy Terror birds more likely died out by climate change, what you say is pure speculation and not a fact, most terrorbirds moved to North america too, also a lot of mammal predators went extinct in that time frame.
@@Vratty There is no evidence of such mass dying in South America when the terror birds went extinct. The only major factor that changed was the introduction and rapidly expansion of large mammalian predators.
@@gamesguy They weren’t as efficient predators. They were. This is proven by the existence of Titanis. That bird evolved IN NORTH AMERICA, lived alongside placental carnivores until its extinction, and became the top predator in the Southern US after extinctions at the end of the Miocene wiped out animals like Amphimachairodus! Titanis did quite well! There’s actually a pattern in size here. Smilodon and Aenocyon species did not grow to larger sizes until the extinction of Titanis 1.8 mya, which implies that it was not the mammals that ruled the roost, but the bird instead. Also, no, Titanis did not “outcompete” these mammals either. It was simply lucky enough to be the first to diversify and fill the apex carnivore role. When carnivorans got to South America, they outcompeted them. Large terror birds were most likely extinct in South America by the GABI, though looking at Wikipedia’s page on Devincezia, the timeline had it surviving from 9-4 mya, from the Late Miocene to the Early Pliocene. But, it would be awesome if we could find fossil evidence of Devincezia surviving into the Pleistocene and coexisting with large carnivorans. But no, this animal was not outcompeted, due it being the last large South American terror bird, going extinct 1.5 million years before the GABI. The bird was driven extinct by climatic changes.

Don’t think an allo would do so we’ll head on with a rhino tbh. Lower centre of gravity, horn and wild aggression. If the rhino knocks the allo over its fucked.
Allosaurus would be hunted to extinction by humans in modern day. Poachers and exotic hunters especially. He can bypass a fence, but can it bypass a .50 cal to the chest? Great video btw
Forget Eggs, Elephant Birds didn't have razor sharp teeth the size of a machete. You'd have to be soft in the head to tackle an Allosaurus, one of the longest surviving apex predators to have ever existed and was so for a reason.
The _Allosaurus_ ranges in medium to large class at about 25-32ft long and stood taller than 9ft. But matched with many adaptations, it is a cardinal sin to accuse a single 1 to 3 ton theropod as incapable of killing an African Bush Elephant.
Allosaurus:(lays lots of eggs) Human:(makes lots of omelets) Maybe we should be doing these experiments when humans can't put poisoned carcasses, use grenade launchers, or burn over allosaur nests. Okay, that's a pre-sapiens possibility. But at least put it in the stone tech days. If people hunt elephants, they will hunt allosaur that break their log fortress walls. What dinosaur would you bring to the mammoth steppe?
Nice! I would love to see more vids like this, like what if dromaeosaurs like Velociraptor or Deinonychus or Dakotaraptor (or even all three?) were introduced to modern day Eurasia? Or what if Sauropods were introduced into modern ecosystems? Or the reverse, introducing modern day animals into Mesozoic ecosystems?
Cool! I got a few ideas for future videos: 1. What if Ankylosaurus was brought to the modern day? 2. What if Edmontosaurus was brought to the modern day? 3.

What if Utahraptor was brought to the modern day? 16. What if Pectinodon was brought to the modern day? I hope you like these ideas. 😊
It would be great to make a video about the impact of modern mammals during the Mesozoic, in my opinion, the carnivorous order, be it felids, canids, mustelids, etc. would do very well during the Cenozoic, especially in the Triassic and Jurassic, where there was still no as many giants as in the Cretaceous, they would do tremendous damage, dominating niches of small animals. Rodents would do very well too, Cetaceans could perhaps do well, and primates could also adapt well to the Cretaceous, because there were already fruits, not in the same diversity, but I think it could support primate species.
Regardless of the fact, that allosaurus would lay quite a few eggs they would be eaten by many. That’s providing food for many of the predators out there .
I reckon Allos would eventually adapt to hunt buffaloes to survive as a population because they're far more numerous than giraffes, hippos, rhinos and elephants, all of which could give the Allo a hard time.
Rhinos... sadly due to humans would be lacking defensively. Their horns are either already cut off or have shrunk a lot thanks to humans hunting them for it. Their terrible eye sight could lead them to be a pretty good prey item. Hippos might have to change their tune a bit, their notoriously aggressive territorial behavior could really backfire if they decide to go after an Allosaurus. Giraffes would just bolt on out of there and should be fine mostly. Elephants would be the most interesting to see how they handle things. They are mighty intelligent after all, if male bull elephants are suddenly on the menu table of something do they start forming mini groups themselves for safety? Similar to Rhinos their tusks have been shrinking a lot in recent years as well due to the most impressive 'tuskers' being targeted by hunters and poachers so defensively they'll be lacking a bit. Can an Allosaurus deal with a herd of Elephants or would they just opt to go for easier prey like water buffalos?
@@AxeiaaNah. Las jirafas escaparían de el. Los elefantes son el doble de grande que el y no les hará falta sus colmillos pará partirle la madre. Los Hipopotamos son principalmente acuáticos y por ende no tendrían tantos problemas y ojo que aún así podrían defenderse fácilmente gracias a su piel dura y enormes mandíbulas. Y con el rinoceronte la verdad sería extraño y alavés el más curioso.
This a very infesting thought experiment. I think out of all the midrange to large theropods, Allosaurus would fair the best in the modern day. They had the right combination of size, speed and power to take advantage of Africa’s larger herbivores. And at younger ages, they would be age to hunt the plethora of small to medium sized ungulates (Oryx, Kudu, Antelope, Wildebeest, ect.). After reaching their adult size of 1-3+ tons, literally no other predator would try to steal a kill from them. And they can use that size to steal and scavenge from other predators when needed. I can imagine an Allosaurus just walking up on an entire pride of lions and steal their kill and they’d just let it. Not wanting to be on the businesses end of it jaws or claws. I also feel like people underestimate Allosaurus when it comes to the match up against Elephants. While true the average Elephant outweighs Allosaurus by 2-3 tons, it’s not like Allosaurus wasn’t familiar with hunting prey in this size range. One species of Stegosaurus that it loved alongside and likely hunted, weight about 5 tons as well. Then of course there the many sauropods it lived alongside in the Morrison Formation. Allosaurus wouldn’t have gone after adults, but juvenile and subadults were fair game. Heck, even at those young ages these sauropods already reached sized that were either equal to or even surpassed modern day elephants. Allosaurus also had the physical tools needed to hunt the African megafauna. It had a powerful bite force that surpassed modern day crocodiles, and it’s blade-like serrated teeth were perfect for slashing deep into flesh and causing heavy bleeding. Long, fishhook-like claws on powerful forearms perfect for grappling prey. Had decent binocular vision and could run between 20-30 miles per hour at its full adult size. It’s should also mentioned that new studies show that Allosaurus feed in a manner to hawks and kestrels. They’d pin prey down with their powerful clawed forearms and/or feed, and start stripping of chunks of flesh while the prey was still alive. Letting blood loss and shock to the rest. When it comes to large prey, Allosaurus could have been “flesh grazers”. Taking bites of flesh out of sauropods that were enough to sustain them without causing lethal damage to the prey to it can heal, while also not having to expend the energy to outright kill it. Allosaurus could have very easy done the same with Elephants, hippos, rhinos, ect. Of course there’s also the subject of pack hunting. Other then tyrannosaurids, Allosaurus and it’s relatives have the most evidence for cooperative hunting. Even if it’s just a pair, or maybe three fours adults, there wouldn’t be ANY manner of Africa’s megafauna that could stop them. Also there’s also the option of gregarious mobbing, where they just gang up to boost their odds in manner similar to Komodo Dragons. Allosaurus was the most successful theropod in the Morrison Formation and likely Late Jurassic North America for a reason. And if they were brought into the modern day, I think they would be just as successful if not more so.
Don’t forget that allosaurus have a bite force of a gray wolf or lion, they may also have been sized reduced in the modern times, so it could have been less damaging to the African ecosystems, we may also have African allosaurus already, more research needed for this possibility tho.
@@BUCK_23CHAD On top of that: allosaurus didnt rely on its bite to hunt, it used its giant claws to pincer down its prey like eagles, and while the large animal struggles itll eat them alive with their slicing teeth leading to massive blood loss and death. Also, i am not sure why you think allosaurus size would be reduced.
A recent study from 2022 estimates allosaurus bite force at around 4400 newtons at the anterior part of the jaws and about 9389 at the posterior part of the jaws which i think is about twice the bite force of a tiger if i remember correctly. So no, allo didnt have a bite force weaker than a lion and adding the serrated teeth and we get a deadly predator.
@@deadtake2664 Like the outdated Allosaurs bite force, the 650 psi bite force for Lions is also inaccurate. That was a juvenile that was measured, adult Lion's bite force should be closer to that of a Tiger, around 1050 psi.
That you even took time out your day to mention that lions wouldnt be able to prey on the giant megapredator 10x their size made laugh out loud. _Lions_ are the ones on the menu!
The documentary "Valley of Gwangi" showed us that an Allosaurus would easily pone an elephant then sit on a church organ before ultimately being burnt alive in that church.
It would effect big cats, and lions the most, but it wouldn't be as bad for them as you're saying. A young allosaurus would make for tempting prey especially for leopards who can kill large silverbacks. Just depends on when mama al stops acting as a guardian.
I loved the movie about the life of the Allosaurus, I just really wish that I could have lived when they lived, no matter what would happen,,and I am very sad 😞 that the asteroid hit the earth 🌎 and caused the destruction of all life forms, except for very small animals,,The movie was entitled Big Al
Allosaurus being prey to leopards, now that's a good joke i have heard Bro incase you forgot they are predators with thich Armour and jagged teeth One bite and it's over for the squishy mammals.
@@aiperthatgotmutatedbytruth5638Did you missed the word "young" here? Obviously leopard is no match for the fully matured Allosaurus but the hatchling and juvenile are still susceptible to predation from Leopards
At issue is egg laying and sub adult care. Some indications were that dinosaurs incubation period was much longer than comparably sized modern birds. Also, 2 tons is max size not average size. Average size would be about twice lion-sized. Young allosaurs would be as liable to predation as monitor lizards. The eggs would attract numerous nest raiders - unless allosaurs had nest - sitting habits, there might not be allosaurs to survive to continue. Human interaction would be swift and lethal. Crocodiles get away with their depredation because it's restricted to rivers and lakes. Allosaurs would have a higher metabolism., eating more often. I somehow feel they would treat humans as part of the food chain, even more than other mammals do. Also, oxygen levels in the atmosphere were higher in the Jurassic, than in modern times. This would affect their size. And ability to hunt - like a sea level sprinter suddenly dealing with Denver altitude air density. Extreme exertion would suffocate them. If they adapted, your 2ton carnosaur might, in a few generations top out about lion-sized.
The Mesozoic had plenty of egg thieves so I doubt that would single-handedly end the species. Also 2 tons is not a maximum size, we’ve found serval individuals larger.
I have a video idea if you want to make what if Carcharodontosaurus and Sarcosuchus were still around today in Africa? All mega fauna will freak out especially rhinoceros elephants and hippopotamus
Air density too low , not to mention the percentage of oxygen. For the allosaur it would as if it were living at 50,000 feet. It definitely couldn't stand toe to toe with anything in the modern era without cardiac arrest. Dinosaurs died out cause the world changed. The atmosphere of their day was at least 5 times thicker, which means that even if the oxygen ratio stayed the same they would still breathed in 5 times as much oxygen as creatures breathe in now. I would say if you placed them in the African savannah they wouldn't last long. Between the rarefied air, prides of lions and mankind they would be gone in weeks, maybe days.
The cheetas would be just fine. I think the lions would merk an allosaur. But let's not forget the deadliest super predator and allosaurus would have to contend with. . . . . US!
IN OUR OWN COUNTRY, THERE WERE ALSO LVING ALLOSAURUS. WE ARE CHINESE. IN CHINA, WE CALL ALLOSAURUS（NORTH AMERICA）ARE 異特龍（UNUSUAL DRAGON）AND THE CHINESE ALLOSAURUS ARE 永川龍（永川 DRAGON）AND 永川 IS THE PLACE WHERE FIRSTLY FOUND THE BONE FOSSILS WE USE THE COMMON CHINESE CHARACTERS TO RENAME THE DINOSAURS AND OTHERS PREHISTORIC ANIMALS IN ORDER TO LET THE COMMON CHINESE PEOPLE CAN UNDERSTAND THE MEANING OF THE PREHISTORIC ANIMALS EASILY. WE DO NOT USE THE ANCIENT GREEK AND LATIN SINCE WE DO NOT KNOW
Does it taste good, have an application in traditional Chinese medicine or have body parts that make good leather? If yes, then we know how it would go.
Sadly i think it would be up to the humans on whether or not the allos survive, Humanity overcomes literally any predator and an allo would be a walk in the park for us.
My favorite dinosaur of all time would have an absolute field day in the savannah. And I would be cheering them on while I sit on the sidelines. Hey, this is cool - one of them is coming up to me right n-
Agility of a Lion would just kill the Allosaurus. A Lion would just bleed him out and it would be over. The Allosaurus or even Trex only hope is that the Lion makes a mistake. Without that they would never be able to catch the Lion. The Lion understands to stay away from a Hippo's mouth. So he would understand to stay away from the Allosaurus and Trex mouth.
Allosaurus's modern niche would have to be scavenging, right? At least if they are solitary. It cannot hunt elephants unless it hunts in packs, which, granted, maybe it would. It can't catch giraffes or anything smaller than a giraffe, and it certainly can't sneak up on anything in the savannah where everything is keeping a keen eye out for stealthy cats. Rhinos it may be able to catch but there aren't enough of them to be a plentiful food source. Maybe it could gorge itself on hippos. Allosaurus is probably faster than hippos on land, but they would retreat to the water. Maybe it would be tall enough to wade in and catch them in the water even if it isn't a strong swimmer. Alright sure, hippos main solo food source, elephants main pack hunting food source, and bullying felines off their kills to scavenge up a snack. I wonder about the lifecycle of young Allosaurus. Sure the eggs are plentiful, but the young ones would be prime targets for vengeful lions. Young adolescents would be small enough for lions to take down while also quite slow and unstealthy. But again, social behavior would surely change the odds there as well. A group of adolescent Allosaurus wouldn't present a viable target for lions.
The size of allosaurus would be its biggest detriment in the savanna. They would be too easy to spot, making them easy to avoid. They would have to take a more endurance based approach to hunting (similar to wild dogs or wolfs) instead of the typical cat ambush hunting style. Even then, they likely would still struggle for that same reason.
I am certain their size was also an issue during their time, it made them easy to spot. Yet they survived even though the megafauna of the time were dinosaurs with unilateral respiratory system and airsacs which are 2.5x more efficient than mammal lungs. They still hunted thrived. We dont know quite how. They may have hunted at night, or as you mentioned they may have made use of their phenomenal stamina, which btw is far superior to any mammals thanks to allosaurus having airsacs. They may have chased prey until exaustion
You completely forgot to think about allosaurus long years of being hatchlings and juveniles. They would be perfect prey for nearly everything else. Lions, Crocs, leopards and Hyenas would reduce their chance of ever getting a dominant size to a small single digit percentage. So no disappearing of lions and whatever.
@@GabiteEditzCuáles ??? Cerato, Ornitolestes y dependiendo de la subespecie saurofaganaxs y torbo ??? La verdad no creo que sea tanta la diferencia y me atrevo a decir que sería más jodido para las crías la cantidad de depredadores tamaño mediano-pequeño que hay en la actualidad
