@@ashwinpokhrel7809would also be interested in seeing how African dinosaurs would impact the biblical events in Egypt like Exodus. Now that'll be tricky.
If Nile crocodiles were considered emissaries of Sobek, the crocodile God, I wouldn’t be surprised if the Spinosaurus would have been considered manifestations of the guy himself.
Maybe they would write something like this: "Look now at the *behemoth,* which I made along with you; he eats grass like an ox. See now, his strength is in his hips, and his power is in his stomach muscles. He moves his tail like a cedar; the sinews of his thighs are tightly knit. His bones are like beams of bronze, his ribs like bars of iron. He is the first of the ways of God; only He who made him can bring near His sword. Surely the mountains yield food for him, and all the beasts of the field play there. He lies under the lotus trees, in a covert of reeds and marsh. The lotus trees cover him with their shade; the willows by the brook surround him. Indeed the river may rage, yet he is not disturbed; he is confident, though the Jordan gushes into his mouth. Can you draw out *Leviathan* with a hook, or snare his tongue with a line which you lower? Can you fill his skin with harpoons, or his head with fishing spears? Lay your hand on him; remember the battle - never do it again! Indeed, any hope of overcoming him is false; Shall one not be overwhelmed at the sight of him? No one is so fierce that he would dare stir him up. I will not conceal his limbs, his mighty power, or his graceful proportions. Who can remove his outer coat? Who can approach him with a double bridle? Who can open the doors of his face, with his terrible teeth all around? His rows of scales are his pride, shut up tightly as with a seal; One is so near another That no air can come between them; They are joined one to another, they stick together and cannot be parted. Out of his mouth go burning lights, sparks of fire shoot out. Strength dwells in his neck, and sorrow dances before him. The folds of his flesh are joined together; They are firm on him and cannot be moved. When he raises himself up, the mighty are afraid; Because of his crashings they are beside themselves. Though the sword reaches him, it cannot avail; Nor does spear, dart, or javelin. He regards iron as straw, and bronze as rotten wood. The arrow cannot make him flee; Slingstones become like stubble to him. Darts are regarded as straw; He laughs at the threat of javelins. His undersides are like sharp potsherds; He spreads pointed marks in the mud. He makes the deep boil like a pot; He makes the sea like a pot of ointment. He leaves a shining wake behind him; One would think the deep had white hair. On earth there is nothing like him, which is made without fear. He beholds every high thing; He is king over all the children of pride." This is a description of two kinds of dinosaur, if it is read honestly with an open mind.
Here’s an idea you can tackle: what if the KT extinction event had been a little less severe, and some of the smaller species of dinosaurs and other animal groups that went extinct with them managed to survive? How might they evolve during the Cenozoic with the changes in plant life, oxygen levels and climate? And would the mammals, reptiles, birds etc that really did survive still be able to evolve as they did?
@@wildbill9490 well even with the higher amount of oxygen they wouldn’t reach that size it took a combination of hollow bones and potentially air sacks to help the bigger ones like sauropods get to their big size
I was thinking the same, as the video starts it is obvious that the large theropods like Carcaradontosaurus would totally go extinct without mega-fauna to hunt but the smaller ones will survive and those would be the ones to evolve along the mammal herbivores starting and arm race between them pushing size and other adaptations. Would be interesting to see speculative evolution of smaller allosaurids as the cenozoic progresses.
I think this underestimates pleistocene H. sapiens, I could easily see some groups building larger fortifications and traps in response to big theropods. Even with preservation bias against it, there's now plenty of evidence for hunter-gatherers building bigger and more elaborate structures than we used to imagine.
I think so too if my ass can come up with traps made out of wood and can sharpen stakes I doubt the ancient human wouldn’t be able too . I think it would make us more aggressive if anything . Since we would probably develop even quicker to see how better we can bring it down . You’ll probably have the balista earlier on or even the pike earlier since we would use reach to get to them first or even fire .
true. H. sapiens were known to trap animals in good locations, using a gorge or cliff to cutoff escape so probably would have a good chance at taking one down if they enough hunters. I think this is why H. erectus did so well. They had ingenuity and were tool users. If your survival depended on removing a threat to the group, you'd bet every day they would be thinking about how to solve the big meanie problem in the neighborhood.
Add in the fact that bows and spears are much better for taking down mega fauna then 90% of moderns day guns. The reason for that is that spears and arrows have a much larger mass than bullet and therefor slow down less when encountering resistance. That is why guns are useless underwater but harpoons still work. This is also why bigger animals can withstand firearms as they simply have enough layers of thick fur, bone and blood to slow down bullets before they truly impact vital areas. Granted that its barely enough but enough is enough.
@@pauls5745 I also feel that modern humans, or even proto-humans, would probably start targetting young theropods as soon as they weren't being protected by their parents (if indeed they were given parental care, I don't what the consensus is at the moment). Hell, given that a lot of African herbivores today will kill baby lions and other predators if they find them without their parents, I could see juvenille theropods being subjected to an absolutely brutal hazing period when they gain independence and which might prevent them taking over the ecosystem.
10:50 small correction: Megistotherium went extinct in the Miocene. Biomes may also play a huge role. Cretaceous Africa was a lot more forested than today. The smaller predators may adapt but the larger predators will struggle to ambush. It's also possible that the elephants can used their tremor sence to detect the invaders and make ambushes difficult. Is also worth noting that the larger therapods may hunt their prey into extinction here as elephants reproduce very slowly. Calves could also be vulnerable to hit and run attacked or the predator just grabbing a baby and running. The therapods win the battle but loose the war
Main issue with tremor senses is dinosaurs were likely adapted for low frequency sounds, and theropods were likely hunting prey that had adaptions similar to elephants when it comes to hearing low frequency sounds, so I doubt that would be the main issue. Also another thing is, while yes, I do believe Elephants would suffer, it would really depend on how much of how much Megatheropods you having, by that I mean how much of the population. If it’s something like 20,000 of each of these Megatheropods, then I doubt they’ll have much issue. For example, prior to the 20th century, they were over 25 million African Bush Elephants in Africa according to Our World in Data. Now it’s unknown how many of these large extinct elephant genus were there, but if I were to guess, at least 100,000 because I really don’t see a large species having a population smaller than 100,000 and they were quite common at the time.
@@denistyrant that's very fair. Although if I remember correctly the megatherapod population study used modern predator populations as a guideline, which also suffered a decrease in population. I also think that study only counted adult individuals. Even if only 20k of a species of Therapod was released into these environments with millions of Elephants, I still see a few extinctions happening because now adults are being hunted when they used to be almost immune to predation. With slower reproduction and no adaptations or behaviours for defending against, many will go extinct. Some may adapt, but many will suffer. Although I'm not sure how many will die off or if they may survive until the megatherapods die out due to them living in a less forested environment than what they are used to
This assumes 2023-24 Elephant populations. Before mass hunting by humans with firearms and human habitation of their territory, Elephants existed in the tens of millions in Africa. Not the paltry number we see today and assume is natural. While there will be growing pains as the predator prey relationship is established, it will find a balanced equilibrium. Besides, there used to be even more species of Elephants in Africa before human interference, such as the North African Elephant.
I think the only TRUE challenge for large theropods (i.e. Carcharadontosaurus) during the Pleistocene would be Palaeoloxodon recki thanks to their more robost frame in comparison to the earlier members of Deinotheriidae and their longer, powerful and forward-facing tusks. Other than that I think they would thrive pretty much unchecked.
Hm don’t think so, fossil evidence shows that large theropods were smaller than their contemporary relatives in colder regions while mammals generally become larger. but yeah it’s just not that interesting when you’re just looking at Africa.
@@vinny184 Yup species like Nanuqsaurus were definitely smaller in the colder regions but that may be because that's the size limit for giant carnivores in the Tundra region, because other smaller predators like Troodontids were much larger in the ice covered regions than their relatives in the tropics.
@@vinny184 Mammals might get larger in cold climates. But they still never got close to even the medium sized Theropods like Nanuqsaurus. Dinosaurs just have an entierly different size potential. A modern polar bear is still the biggest mamalian land carnivore known today and a polar bear is a joke compared to most medium sized Theropods.
I think the factor people are not considering is adaptability. A large theropod is limited to eating large herbivores, whereas mammalian carnivores can eat anything from arthropods to large herbivores.
Love these videos. Feel like you should have mentioned mammalian teamwork more often. Proboscideans show herd behavior for much of their history and often not in the tiny 20 strong herds of the modern day.
Fair enough, but please keep in mind the video title: Could Giant Theropods Survive in Africa? This is a video on whether or not Theropods can survive Africa, not on how Mammals can survive the Theropod invasion.
@@jkjk7423 oh sure and I don’t disagree with the conclusions it just seems like coordinated herds would have been something they hadn’t delt with on that level.
@@Gingerbreadley That's true, though I think the same can be said for the probiscidean herds themselves. So it kind of evens out the unfamiliarity for both parties.
What makes you think that elephant sized or bigger sub adult sauropods were not foraging in herds? Even the adults are speculated to live in herds, if not so I don't think theropods would have always hunt alone not the co-ordinated pack behaviour but they can attack in groups.
when it comes to homo sapiens I think you forgot to mention one crucial strategy for fighting dinosaurs. big fire. Many fire very big. its incredibly effective as a defensive strategy and is easy to do with low levels of technology. It requires a fair amount of set up to be sure, but I can absolutely see humans using big fire to scare a carcharodontosaurus into falling off a cliff. Also, big rock. climbing into a tree or up a cliff side and throwing large rocks would absolutely work. The abelosaurids I can't imagine being that much different from like big cats.
i think numbers and intelligence are being disregarded on a lot of matchups, especially the elephants, hippos and humans, i can see a family of hippos demolishing a spino, same for elephants and many other of their larger relatives with charcharodontosaurus, i mean, brains and numbers really allowed huans to thrive against larger predators before, there's also the african meta to outrun your predator to survive, so smaller animals will have a chance and since they are small the theropods will need to eat more of them
@@playernotfound9489 they'd still go extinct, humans cant be caged, people like to self-hate on their own species for some reason when we're alot more powerful due to our extreme intelligence. People underestimate intelligence too much.
One issue I have with this video is it goes deeper into feats and not into psychological intimidation or into tactics. Humans walk up to a pack of lions and take their food. All intimidation. Humans being way smarter than other animals is the real equalizer. I think a simple comparison of size does nothing to make up for things like fecundity, reproductive success, and some real x factors here like the human desire to kill the biggest, nastiest prey possible. Humans are perfectly capable of laying a trap and goading a therapod. I think the Pleistocene would be a lot more challenging than is given credit. Humans will remember a specific animal for a decade and devote multiple attempts to kill the same creature based on reputation. That tenacity is unmatched.
its always a size comparision. not the fact that humans can team up with other humans in hunting than any other ceatures. Especially when fire is involved.
@@aldrinmilespartosa1578 To be fair I think this argument also equally applies to big cats and canine species that hunt and live in organized groups. Yes, these large therapods are often bigger, but they are not strongly reported to organize to quite the same extent.
Wouldnt most of the larger therapods have issues simply catching the mammals? I thought anything that would be likely prey could run substantially faster than therapods which were used to predating slower dinos? Its also most likely that more recent hominids would specifically target therapod nests / eggs / young in order to deliberately wipe them out.
Simply catching the mammals? I think the hadrosaurs were really Swift and theropods still preyed upon them so the bigger bovids like buffaloes would be an ideal prey, and yes about catching fast prey ambush hunting is not something out of the box. And yes the ave like respiratory system was much more efficient in sustaining prolonged hunts, so stamina is great, they also need much less prey than the mammals of their same siz so even in times with scarce food they would still do better than the mammalian carnivores. And yes dinos were animals with great parental instincts and yes they reproduce like crazy and if we are introducing a healthy number of species that number would be between 350-1000 individuals to begin with so unless one decimates every single egg or younling (avoiding the adults)it's not something to possible.
Especially more intelligent animlas like elephants that in family groups could likely give the larger therapods a hard time. In their native environment the therapods had no predators except others. I doubt they be able to cope with say a dozen bull elephants charging one of them. But other mammals i susoect could just run away making it much harder for therpods to catch them unlike their normal prey which they likely matched for speed..
A dozen bull elephants would never travel in herds heck they had a couple million years to change that solitary nature, when the homo genus was specifically Targeting the lone males but that didn't happen so there is no need to speculate a scenario where they do! And yes the matriarchal herds can always fall to predators that attack in mobs (not coordinated hunts). Plus the respiratory system of giant theropods (atleast carcharodontosaurids)was meant to hunt prey for long time, they could have sustained their speed for a longer time.
It definitely wasn’t the highlight of the vid, but I’d like to point out that Megistotherium Osteothlastes was legit just Battle Cat from Masters of the Universe. It’s wild to me that there was a carnivoran THAT big
Im very interested in how the mammals would adapt to the theropod's presense. I love keenan Taylor's exxecution of it with some probosodians becoming smarter and having more complex herd behaviors while deinotherium decreased brain size and got armor and faster reproduction
I think mammals overlapping the giant reptiles mostly were small critters to avoid being a meal. They could be very hard to catch, so mammals likely would all evolve into fraidycat stealth creatures. Heightened senses and colony life would make lots of mammals into what the rodents are today. I was thinking therapods might only last 10-20k years if you take them out of their time. They wouldn't have enough time to change their body plan, but 20k years in mammalian history is enough time to adapt to changing conditions. That's what mammals pushed as a prime survival trait; Adaptability to different survival pressures. They are generalists for the most part, where reptiles just seem to be so specialized, and I assume that applied to therapods as well.
I live in Africa.If they where in modern day Africa I give the entire population of miscellaneous megaTherapods of the mezozoic 24 hour tops and thats a very generous estimate.
lol and I’m from Africa if these animals served to modern day Africa our time humans most like wouldn’t have had a chance to evolve will still be up in the trees were it’s safest, lol these are not cats they are literally giant 2 ton possibly 10ton carnivores😂
@@darwinmini8332 modern humans I get Our ancestors wouldn’t be able to evolve with big theropods on the prowl These aren’t like any mammal predators that have come before
The video was good, seeing how ancient theropods face new challenges is relatively surprising, although it would have been better to see how the megafauna adapted to these new predators, especially the proboscideans and rhinoceroses, they could evolve to become stronger and durable (elephants with tougher skin, more resistant tusks designed to pierce their predators or becoming larger to be able to better defend themselves against herds of some of the large theropods that will be facing in this scenario), I would also think about humans primitives being able to use the jaw bones of some theropod to improve their spears and arrows along with using their own skin to make durable clothing against attacks from other small predators or decimate them with fire at cliffs and even use arrows with fire in the best of cases. It would be interesting to see these topics for future confrontations of megatheropods against megafauna and how the latter would improve to face them in a better way. Carcha seeing small beings that do nothing but observe: look, they are human, they are real!!!!, take a photo with them carcha watching how those small beings are evolving and reducing their gigantic food resources and soon they will be the hunted: oh no brother
lol yea all that highly unlikely but fair speculation and to be honest i doubt humans would even evolve with these giant elephant sized killers running around.
@@kwnstudio1421 As they would say: there are infinite possibilities and although they may sound crazy, they can happen. Maybe we live only with fire and spears against those same elephants and in the end we end up dominating them (along with their predators), although I am sure that we would have fallen behind in technology before those predators but nothing is impossible, we have survived worse things like pandemics and infections that almost extinct us, but even with that...we are still here to tell it! 🗿
@@subnombre Lol those pandemics are relatively nothing, some 60 thousand years ago humans “homo sapiens” almost went extinct due to some volcanic event which whipped out a significant amount of our genetic diversity. The humans alive today are their descendants. Lol you sure do like to over estimate us which I don’t blame most people for doing so like look at how much we achieved it’s awesome👍🏿However it was a tough grind to get to this point owe it to your ancestors. You have to keep in mind for a majority of our species existence we lived as hunter gatherers if it weren’t for some plants and animals being domesticatable you and I would still be living in tribes throwing spears and not a damn city or village in site this is the reality. Another thing is humans are such an unusual animal any other natural changes at that crucial time in the great rift valley would have prevented our evolution we are hella lucky my dude. And to be honest ever since the dinosaurs elephant sized terrestrial predators haven’t existed ever since we are damn lucky and raptors? Hell nah I’m good😂
@@kwnstudio1421 1-it remains the same, several humans will end up improving and adapting to that more hostile environment (sorry for my mistake of combining all genders of humans for the same environment, although it is a good point, evolution and adaptability will continue to contribute to us) 2-And as I said myself *"we would have been further behind in technology with these huge predators"* I never said that we could simply ignore them, you just put something in that I never said, and yes, it all depends on the ancestors who survive the attacks of the new predators and you even make it clear that it would be difficult (I even said it myself) so you don't answer anything hand 3-events that can be overcome with some of us to adapt, apart from everything you say is lowering only us, wouldn't it also be good to lower the dinosaurs from the video with those same catastrophic events??????, simply We wouldn't be the only ones affected. You didn't answer anything at all and I will continue with my base, the humans would end up defeating the dinosaurs. 😂
Your also forgetting how modern elephants don’t run away if they see one of their own get attacked it’s usually and entire stampede that will attack hence why only humans actually kill them and not lions unless if the elephant is a baby or hurt or by himself and even then they rather not
Ah another great vid. I have to wonder how theropods would change the trajectory of early man if they were to survive this new world. While they would make an impact they might actually be better than the predators we did face as most theropods would be more noticeable, less attracted to eating humans, and would possibly leave better resources for tools and perhaps in some cases leftovers. Sure there would still be attacks on humans but most would not think it worth the effort after killing one of us only to realize everyone else fled away to safety. Perhaps these titans would have sped up our advancement in technology? With these large possibly highly socially intelligent animals being capable of being tamed and put to work. The need to feed these animals leading to earlier herding of prey than was seen in our real timeline. Of course this is just one speculative outcome but things like this are fun to ponder.
I think it might be the opposite, human history is filled with us near wiping out animals due to our notion of revenge. Attacking one human resulting in having hundred of humans hunting you down throw sticks and stones would lead to the same instinctual avoidance most animals have of humans. But at the same time their size making it too dangerous to domesticate, resulting in a situation where they have such a reputation of being so dangerous whenever someone reports seeing a dinosaur large hunting parties are put together like what used to happen with bears, lions, mammoths and elephants. The roll dinosaurs would have played in human these societies may have slowdown human development as tribes wouldn't need to farm due to the amount of meat dinosaurs provided.
Love speculative videos like this. I really think you undersold the struggle for food large therapods would endure during the Paleocene and slightly less so the difficulty therapods would have against animals with frontal defenses like arsinotherium. Also, can't forget that dinosaurs are just animals, not killing machines. Human tools would have absolutely worked against them, to great effect.
Human tools would have no advantage against a massive carnivore like a theropod, sheer size alone of just one theropod would destroy an entire village of humans easily. Humans would go extinct in this timeline and quickly too.
@@richardbug3094, hard disagree. dinosaurs are animals. Animals that feel pain and, even more importantly, fear. Tactics would be different, sure. Humanity would be more inclined to create stronger settlements and travel less. The dinos would absolutely not just rampage across the world though. Leave that to the movie monsters.
One of these on North America would be nightmarish, multiple Tyrannosaurs like T-Rex, Albertosaurus, and Dapletosaurus plus other large theropods like Acrocanthosaurus, and smaller ones like Dakotaraptor
As a Kenyan this video is awesome Africa has fascinating animals both mammal and dinosaurs I believe there's more Carcharodontosaurs out there in Africa to be found it was without a doubt Africa's scariest strongest and largest land carnivore that being said you should do videos like this for other continents I encourage you✅
Id love a fantasy series where these dinossaurs evolve along side these mamals. Instead of staying the same, they grow smaller and smaller, but still distinct from terror birds
I think humans could have wiped out the abelisaurids, mostly due to how comparatively small they were, and due to how intelligent and vengeful we are. Humans would definitely destroy entire nests and young of abelisaurs when they could, and would definitely develop hunting strategies to kill them. I could see pitfall traps being very effective. I could also see a pit fall accidentally getting an carcharodontosaur stuck, if one stepped in the pit. It would be a very awkward position to try and get up from. Also, it’s possible the all the theropods in Africa could cause humanity to leave earlier in an attempt to escape them.
If wiping out the abelisaurids and other smaller theropods was realistic then lions, hyenas and other native predators would've also been wiped out. Undoubtedly, humans would absolutely be capable of taking down individual theropods including, as you said, the odd charcharodontosaurus every now and then, but they certainly wouldn't be able to do this to an extent where it would impact any of the theropod species' populations. On top of that, there's simply not enough motivation for humans to actively wipe out theropods - the risk is too high and there's no way for them to know if such a thing is even possible, considering how extinction was considered a scientific impossibility until surprisingly recently. If all that isn't enough, the theropods themselves aren't stupid. Even if the humans somehow managed to coordinate themselves on a mass level and began to actively hunt theropods despite the danger and impracticality of doing so all they would likely achieve is make them smarter. Archosaurs in general tend to be very adaptive and intelligent, I wouldn't put it past most theropods to learn the extent and functionality of hominid traps and weaponry within a few generations, if not within a single generation, taking their lifespan and the likelihood of said traps to yield effective results consistently.
You could use these same arguments to suggest that humans could've wiped out big cats, except they haven't. And big cats are even smaller than abelisaurids and reproduce at a slower rate.
@@siamzero9480big cats are endangered bc we changed 99% of the surface of the planet, not bc we spitefully hunt them. even when we do hunt big cats it’s usually to protect livestock or for furs

It would also be interesting to speculate how manmals would have evolved to deal with dinosaur predators. Most antelope species could outrun any dinosaurs. Elephantine relatives might defend themselves by travelling in herds and collectively fighting the theropods. Rhinos might develop longer horns to attack predators.
I think speed and intelligence would be the mammals' most successful survival mechanism. Even the largest mammal to ever live would've been no match to the largest of the theropods...but the fastest mammals could run circles around most theropods. Intelligence would be key, especially to bigger mammals that the dinosaurs would be most interested in eating. As you said, elephantine relatives fighting collectively as a herd could stand a chance against even the biggest theropods. It's also highly unlikely that a theropod would be able to outsmart elephants or their ancestors.
an episode on south america and asia wouldve been interesting, for south america the thropod team wouldve consists of austroraptor, skorpiovenator and carnotaurus, while the medium lineup can consists of ekrixinatosaurus, orkoraptor, oxalaia, megaraptor and aerosteon, while the big heavy hitters wouldve obviously been the giganotosaurus and maybe the addition of maip. i think they will have a more difficult matchup cause south america will be home to huge predators like some of the terror birds and sebecid land crocodile and for the herbivore, they will have to compete against giant ground sloths, glyptodonts, and the invading mammals from the north later
You know South America is home to huge Carcharodontosaurs 3 of them are one of the largest land carnivore the world has ever seen (Tyrannotitan Mapusaurus Giganotosaurus. Giganotosaurus is the 2nd largest land carnivore in the world) they won't worry much from terror birds big cats bears and so on even carnivorous mammals coming from North America none of them comes close to the terrifyingly huge size of the carchs they were titanic killers just like their African cousins giant sloths and other giant herbivores will have a bad day facing those creatures they've never seen a land carnivore bigger than themselves or close to their size no saying they're not gonna be easy prey for the carchs but they'll pretty much overcome them as they'll end up in their meat menu dinosaurs are scary for real most Abelisaurs are larger than any terror bird and big cats in weight over 1 tonne so they will most likely keep both creatures at bay.

Some of these dinosaurs are already in there, but of course, there will be mods of, of course, some dinosaurs that are officially added to the game.
The answer is no, because by the Cenzoic era,their prey are no longer bulky. After the sloth ,hippo and mammoth are eaten up,the deers,rhino,bison, and antelopes offer little meat to this theropods stonach.
We as a species would definitely be no diff for any adult theropod pre-equalizer, I would contest that the dinosaurs biggest weakness are their eggs and the brooding period.
I don’t think deer or impala would be easy prey for theropods because they are extremely agile and fast. I think they would have a lot greater ability maneuver than the theropods
@@juritudi57yearsago59 theropoda dinosaurs had large extremely complex eyes, sharper than hawk eyes and far more developed than any mammalian eye (mammal eyes are primitive, we can't even see several colors in the ultraviolet).

Yes, plus they themselves have pretty impressive stamina, and can sustain top speeds for a considerable amount of time. Thompson's Gazelles can reach speeds of up to 62 mph, and sustain for quite some distance.
Tbh. the ONLY reason why we dont have guns adopted for extreme sized animals is lack of need. We have similar stuff, but its resteicted by various laws of war fromxgetting miniaturized for taking on soft targets (softer than main battle tanks) 1940s era shaped charge warheads can plow through multiple meters of solid steel armor. Cutting clean through even the largest theropods is easily feasible with hypersonic jets of pressure liquidized copper.
You won't find any bullet that can shot through multiple meter of solid steel. A single meter maybe but that is already stretching it. Do you have any idea how much resistance solid steel gives? Also if we need something that can penetrate longer while encountering resistance from a material such as fur and blood we would simply start launching harpoons and spears instead of bullets. The more mass a object has the harder it is to stop it.
Hot Take: Scenario a: The dinosaur threat would cause Homo Sapiens to migrate much earlier to places the dinosaurs can't reach. A few millenia later and humans are a) much more, b) much better armed, c) armoured and d) much much better organized, which leads to something like a roman army invading Africa and slow and steady pushing the dinosaurs into extinction, cause they are too much of a threat Scenario b: Homo Sapiens won't migrate onto other continents, because they are too scared. So, at some point, the Neanderthals show up - in large lumbers, armed and armoured.
South America invaded by dinosaurs would be wild, as Mesozoic theropods would meet fellow theropods and Barinasuchus which could be easily mistaken for an invader from the Triassic.
aren't mammals like antelopes too quick to be caught? I can't really imagine any therapod being able to be as competitive as they just have evolved to hunt wayyyyy to different of prey.
Varanus ssp manage to prey on antelope, deer and buffalo, and they are just lizards, not the advanced therapod dinosaurs. Prey size would be the difficulty, I don't think a 4 ton predator would be able to catch a 200kg zebra, nevermind a 30kg gazelle. The smaller raptorial therapods would probably find a niche, while still being prey for lions and hyenas on occasion.
@@mala8871dinosaurs, theropods especially, operate differently and are similar to humans. They are long distance runners and can out last most mammalian prey in a long distance race. Although a small herbivore can outrun it momentarily the large theropod would catch up to it whilst it's tired out from running
Fantastic concept for a video, and overall excellently put together. I especially appreciate you addressing the fact that early humans bringing down megaherbivores is a very different proposition to bringing down carnivores of similar size, and also highlighted the difference between the less threatening but much tougher megatherapods, and the more easily killed but much more dangerous mid-sized therapods. I am surprised that you made no mention of Palaeoloxodon recki however, as it was basically the same size as Deinotherium, but the longer, forward-facing tusks would likely have provided better protection from predation.

You're assesment is however based on presumption that everything fights when threatened. For example, ancient ancestors of Gazelles wouldn't be a valid prey for any of mentioned dinosaurs, since these mammals are speed demons, capable of running fast and far. Some other animals as well as early humanoids could hide or seek shelter in remote areas, that theropods could't reach, which wouldn't be that difficult since theropod anatomy doesn't allow for pretty much any climbing whatsoever... Another thing would be a lack of food. With early elephants being so easy to hunt by bigger dinos, they would go extinct and then the dinos would have to hunt far more ineffective prey, which would shrink their population in return...
I miss there: Daeodon, Smilodon, Palaeoloxodon, Dire Wolf, Short-faced Bear etc. But probably even them would stand no chance against theropods, certainly not against the larger ones. On the other hand, mammals would probably evolve into something more effective against theropods (stay small forever, haha). In the ocean it would be also interesting competition.
one thing for these theropods, to keep in mind with the Miocene era, is to avoid the oceans at ALL costs. because monster hyper predators like Livyatan and Megalodon are dominating during the Miocene, those giant ichthyosaurs are long gone, since the triassic, the biggest sea animals during the time of these theropods are the pliosaurs, plesiosaurs, Mosasaurs, and smaller ichthyosaurs
The thing with these dinosaurs that some people seem to forget about is that they had much greater endurance than any other animals. Ostrich has the same breathing system and can maintain top sprinting speeds for 30 minutes vs a humans 1 minute sprint. We would never outrun or exhaust a dinosaur that sprints faster than us for such a longer time period.
It will be like Attack On Theropod 😂😂😂 Where Homo Sapiens build large walls made out of trees and Bark to protect themselves from the Theropods, or live in isolated mountains and caves, to prepare weapons to kill the large predators.
@@insectilluminatigetshrekt5574 flaming arrows is a myth coming from things like medieval movies, in actuality you would need fuel and a material to keep the fire going, and that would need resources early humans wouldnt have been able to acquire by the time, and though we dont know theropod nesting behavior, we do know birds, and we know birds and crocodilians guarded their nests, sometimes in pairs, so theropod dinosaurs doing the same wouldnt be impossible, theyre not resource hungry like sauropod so guarding nests wouldve been possible for theropods
@@insectilluminatigetshrekt5574 also setting their sleeping places on fire wouldnt be a wise choice as these are early humans and they werent that good at controlling mass scale fires yet, and even now, uncontrolled fire can backfire for every living creature in the area, not just the theropods
I think depending on how the dinosaurs and the numbers, Habilus and sapien might be able to hold on for a bit. Humans are pretty terriotial and vengeful, so I think they'd at least learn how to target dinosaur nests or the watch the bigger ones fight elephants and see how it gets hurt and hunts. This might be a good opportunity to see where it can be hit. It would be a lot harder cause these predators are a lot bigger than any mammal predators but I think some group tactics could work
You make a really good point about humans attacking nests. Sure early humans didn't have the weapons to take down adult theropods, but they would definitely be small and sneaky enough to raid dinosaurs nests. Eggs are a major source of protein for humans across the world, and with the theropods taking out much of the mammalian game, early humans would likely put even more focus on egg hunting. Early humans wouldn't beat theropods by battling head to head, they'd defeat them by eating their eggs.
It's important to remember the animals evolving during this time were recovering from a mass extinction. Theropods were nature's napalm. They were designed to limit the massive herbivores that evolved in the Mesozoic. Humans likely wouldn't have had a chance to evolve with this kind of pressure imo. In fact mammals as a group had a hard time competing with these massive archosaurs
I hope the next one tackles Asia. We know in China and Japan and the Korea's and in that area is where Paleoloxodon Namadicus was found but that's also where some Tarbosaurus remains were found as well if memory serves so that could be really interesting to spot. But I am also curious if any wintery aspects about Siberia and such will be tackled as well. I'd love to see something akin to Nanuqsaurus confronting and competing for resources vs Siberian Tigers for example.
It's quite strange how Africa, the last continent where large animals are very abundant, didn't have them until much later compared to other continents like Asia and North America. But it does seem the only thing even the elephants could do is try evolving real defenses against large carnivores. And even then they'd be used to such tricks most likely. Sauropods lived in herds too, and were much larger. Tusks would need to become more like horns to really be used well offensively. Correct me if I'm wrong but I'm also pretty sure elephant immune system is pretty bad, so the flesh tearing blood gushing attack strategy would be extra effective against them. I do see rhinos and hippos fending off theropods of their size and maybe 3 tons or so. Nobody wants to be stabbed in the gut.
You forgot.... the mammals would predate on the eggs and nests of the dinos much more effectively than anything in the cretaceous. How many would survive to adulthood? Not many.
I feel what would have happened is the humans and their relatives would have been pushed out of Africa earlier...The Theropods would have survived until the Desertification of the Saharah. The mid sized Theropods would survive but the larger ones might not have. The pack mammals likely would have survived to modern day but the lone hunting animals may have been replaced by the smaller theropods...Africa and maybe even the more tropical places of India, south China, and Indonesia may still be home to the mid sized Theropods...but Humans would thrive in the northern regions. I feel that the giant theropods would cause gigantism to start to become more prevalent ... more sister species of Paraceratherium and Palaeoloxodon namadicus would be encouraged to grow larger, smarter, and maybe tougher skin to deal with the Theropods. Africa would become a true land of giants with a War between Theropods and Mammals...eventually, there could be smart tool making dinos around the time humans discovered agriculture.
Reintroduce them into even the early Holocene, and it'd be a different story entirely. The lack of megafauna would be a major hurdle, and then you'd have established humans with firearms and organised tactics. The later you get into the period, the bigger threat humans would be. Eventually, you'd see a full-out war on the theropod menace, which is something I desperately want to see animated. Warplanes and tanks exterminating huge carnovores, carrier groups dodging mosasaurs, and the like.
Truthfully speaking, chances are before we even develop flintlock pistols we would already have stabbed every theropod on land into extinction or to be a endangered species. People seem to forget that humans took down mega fauna with primitive spears and bows. That is something most modern firearms would struggle with unless big calibers were used.
I actually do not think dinosaurs would do well at all against mamals. Mamals are faster, more adaptive and more intelligent. Once mamals take hold and become most preys and predatiors, within a few generations, dinosaurs would get out competed by mamals and starve.
Raptor isle birds terror birds sebecids and extant reptiles eagles crocodilians alll contradict this but sure in fact the mammalian predators are the ones getting starved out 💀
You forgot the Elephantinians; ala Loxodonta, Elephas, Mammuthus, Palaeoloxodonta, Anancus, and Mastodons. Still a good video. Are you considering similar scenarios with smaller non-avian therapods as well as other non-avian dinosaurs?
you think they are thriving but you forgot that they cam from a time that had a more oxygen rich atmorsphere to support large sized therapods like most on your list. they would for the most part in these eras bemoving at not their top speeds and having hard times breathing. the mammals for the most part could outpace them and have better stamina
There was lower oxygen throughout the Mesozoic than today. And dinosaurs had bird lungs, which gave them the most efficient breathing system in the animal kingdom. Too much oxygen might make it toxic for them though.
Oxygen quantity has little to nothing to do with dinosaur sizes. Niches did, as well as food sources. Keep in mind only sauropods really peaked past mammals in size, with large theropods and hadrosaurs being much closer to the largest mammals we know about.
I wonder if our ancestors Australopithecus afferentsus would hunt just like modern chimpanzees. Not to mention in Africa when we got to Pleistocene, there were lions, hyenas, leopards, sabertooth, cats, and African wild dogs that would be the competition with the Theropods of Africa. Who knows maybe a large pride of lions could take down a mega theropod just like with elephants and giraffes
It takes a pride of lions a shit tone of effort and risk to take down elephants and most of the time they attack juveniles. Being a possibly aggresive theropod makes me think that it will be very unlikely that lions will try to pick fights with carcharadontosaurus and other large theropods , they would flee from them in most scenarios As for the rest, the majority of the theropods were larger and they would have no problem hunting the larger prey items or just stealing from the mammals and other reptiles.
