Suggestions: Can Australian theropods survive in Cenozoic Australia? Can Antarctic Theropods survive in Cenozoic Antarctica? Can Homo Erectus survive in the Carboniferous Period?
Homoerectus, and we, would not survive the carboniferous because of oxygen poisoning. If oxygen levels were the estimated 35% we would all die pretty quickly. Forests fires were also far deadlier back then due to higher o2 levels. There are still theropods in all of those regions, including Antarctica [Penguins]. But i know what you mean. The mesozoic spanned over 185 million years, you had all sorts of theropods in all of those regions. I am sure there were plenty of theropods that could survive in all of those regions, aside antarctica, which became a death continent when the icesheets didn't melt. I'll add: the large and even medium sized theropods would likely not survive in any of these continents. These animals had high caloric requirements. Today, and through the cenozoic, most megafauna have been placental mammals whos gestation period slows drastically as they get larger. This makes large mammals prone to extinction during climate changes., Unfortunately, this had led to there not being that many massive mammals. During the mesozoic, large animals gestation period didn't slow down with size, allowing for a lot of massive species in just 1 habitat. Trex lived alongside 3 ceratopcian and 2 ankylosaurid species which were as big if not bigger than bush elephants. Plus sauropods are a whole different story. There's too little food in the cenozoic for giant carnivorous theropods
Mind-blowing concept! Imagining these massive dinosaurs surviving in the Cenozoic is insane. Love how you broke down each species' potential and the challenges they’d face. Can’t wait for more of these wild 'what if' scenarios!
I'm glad you liked it! Future installments in the series may include more theropods, but will probably focus on one portion of the Cenozoic like this one did. The previous two episodes were fun, but took way too long to make for how many people watched them, so this model seems to be much more sustainable for my own mental health
This is outdated info Cave bears, just like modern brown bears, had varied diets depending on their location. Some cave bears where very vegetarian whereas others where more omnivorous or carnivorous.

Anyway, congratulations on your new video. I liked it and found it very interesting.
@@TheVividen 100%, ofc doubt the theropods would go up that north, just given how extreme it was temperature wise, that and food would be a bit more limited compared to down south.
Great work! Here are some ideas for future videos: Could Homotherium and Xenosmilus survive in the Mezosoic? Arctotherium Angustidens vs Ceratosaurus Dentisulcatus Could Jagras/Great Jagras [Monster Hunter Franchise] survive in the Hell Creek Formation? Could Northern/Southern Elephant Seals Survive in the Mezosoic? Maip Macrothorax vs Pycnonemosaurus nevesi
4:51 that jumpscares the shit out of me lmao also id replace Guanlong with the asiatic Megaraptoran, Fukuiraptor, just for a more diversified roster of animals
W video I have three suggestions: 1. Could megalodon and angustidens survive the Triassic. 2. Could Giganotosaurus and spinosaurus survive the hell Creek formation. 3. Could paleoloxodon and shantungosaurus survive the Morris information.
think this will affect trex, at least he has no experience with other super predators of about his own category, but most likely there will be no fights. Giganotosaurus will go east and find Alamosaurus, and spinosaurus will most likely have a harder time since there are no large fish in hell creek. Most likely, small trikes and hadrosaurs became food. large individuals either they will be out of priority or unavailable for hunting @@TheVividen
I have not watched the video yet, but one common problem I see in a lot of these scenarios that they failed to mention is that the dinosaurs of the Mesozoic were used to far different atmospheric composition to that of the Cenozoic, not only were carbon dioxide level levels four times as high during the Mesozoic at 1200 ppm, but oxygen levels ranged from 27% in the Cretaceous two as high as 35% during some periods of the Mesozoic dinosaurs would frankly have a hard time breathing in an atmosphere That is much more poor in oxygen.
in the Cretaceous period, there was even less oxygen than there is now, 21%. You may be confusing it with the Carboniferous period, which was 100 million years before the dinosaurs. There was 35% oxygen due to the fact that plants only grew on land and had a great variety. For dinosaurs, the modern era is even richer in oxygen than the native period
@ pretty much every source I can find, including several academic papers from Oxford say that during the Cretaceous period oxygen levels averaged between 27% and 30% while carbon dioxide level levels were between four and eight times as high as modern levels, which is still significantly lower than the Carboniferous period height at 37% atmospheric oxygen content, the larger oxygen content in the atmosphere in it of itself is a big explanation for why Jurassic and Cretaceous dinosaurs were able to grow to such extreme sizes
@@consulargaming3554 what nonsense it has long been proven that in the Cretaceous period there was 21%. read the articles and not Wikipedia about the large size dinosaurs are not insects oxygen does not affect vertebrates extreme sizes were achieved due to the structure
Another interesting video as always! This is actually my second favourite series on your channel aside from could prehistoric mammals survive the Mesozoic! Love seeing could theropods survive the Cenozoic on different continents. Found it quite funny having the Deinocheirus being followed by the Tarbosaurus 😂 However this episode I felt like their were some confusing absences from the roster, is Therizinosaurus technically a theropod dinosaur or is it not? I had thought if Deinocheirus was included surely Therizinosaurus should of been there in Asia too?? Another creature I thought was missing was the woolly rhinoceros as I'm pretty sure they did reach into Asia during the Pleistocene from Siberia so shouldn't they of been in here? Thought they could of been a potential prey item if still dangerous for the Tarbosaurus etc My final question was the pacing. In previous episodes like Africa for example we started off in the Eocene and worked our way up to the Pleistocene seeing how each mammal of that era could handle the dinosaur invasion. I would of loved to see how Paraceratherium might handle Tarbosaurus , maybe they would of been still preyed on though if T.rex in Hell Creek could do it in their own video. There was no mention of the Ngandong tiger either which surprised me considering it was on the thumbnail, overall I really enjoyed watching I just felt like it was sadly rushed in some areas. I hope in the next video in this series we can see Europe and South America covered 🤞
How strong is Tarbosaurus Bataar's Biteforce Ive seen stuff saying around 5520 psi and others at around 8,000/10,000 psi The higher end stuff is what i see more often and consistently but idk what to think.
spears fire and traps would ensure humanity's dominance people seriously underestimate the sheer tenacity of humanity when it wants something dead aslo i bet dinosaurs taste great
Hi Vividen! May I ask what would be the outcome if Spinosaurus (and a few other Mesozoic reptiles, selected for the water-shores environments) would be suddenly tossed into Paleocene South America? More specifically into the dense, suffocating "Hellish Reptilarium" of Cerrejon? My best regards to You!
One thing not discussed in the video is a possible adaptation of Deinocheirus to consume regular plantlife, given the abundance of soft plant matter that grew everywhere. I wouldn't be surprised if a population of Deinocheirus slowly adapted to graze on the plants near the water's edge and become more generalist, further encroaching on the Chalicothere's niche. Another possible slue of adaptations could lead them to consume fish more regularly and remain further north for longer periods of time, not quite to the extent of a Spinosaurid, but just enough to allow them to compete with bears for their niche.
The biggest issue I see for the larger theropods that you seem to have missed, is that they're likely to outbreed their new mammalian prey, and by a wider margin the bigger you get.
@@Devin_Stromgren I also do think that given Elephant intelligence and herding behaviour that they would adapt to Tarbosaurus. I don't think any ceratopcid lived in herds. Adult male bull Elephants would be in a huge bind tho.
7:44 I have to doubt here because Horses too are adapted to running for long distances. Not as well adapted for it as humans, sure but which prey species in the cretaceous was adapted to run for that far, that fast?.
I feel like the part about large mammalian carnivores should have focused more on who would be better at hunting the same prey items than go would win in a fight because given their sizes they will be too much of a danger to hunt each other. Well, with the exception of the largest therapods which may actually be able to send some of those larger bear and cat species extinct but probably just a few as they generally do still have stealth adaptations.
The same factors that led to a massive die-off of Pleistocene megafauna in Asia would doubtlessly affect all these Dinosaurs for sure. I'd be shocked if any of them survive past 10kBC unless they spread to SE Asia or the Malay Archipelago.
I actually still think it's possible for Tarbosaurus to go after Palaeoloxodon on occasion. Predators don't need to be able to defeat prey items in a gladiatorial death match to prey on them, they have tactics like ambush, attacking at night when it's harder for the prey to see, attacking animals stuck in mud/snow/tight spaces, etc. A bull Palaeoloxodon would most likely be traveling alone too. Not ideal prey for obvious reasons, but still doable. The rest of the theropods in this video, however, are most definitely going to leave adult Palaeoloxodon alone.
None of these large theropods were ambush predators which primates are most vulnerable to (e.g. Leopards, Tigers) so Gigantopithecus could literally just climb tree. It would be very easy for them to avoid these large theropods.
hmm... I didn't know Gigantopithecus could climb. I guess I just assumed given how Gorillas are mostly terrestrial I just assumed something even bigger would be entirely terrestrial.
@@AmachiEligwe Gorillas are terrestrial but are still very capable climbers. They just don't use climbing to run away from predator because their only real predator (the leopard) is a very capable climber anyway.
Velociraptors would probably dominate it their niche as small ambush predators, they would probably out compete small cats. Not because they are better but because they are more likely to win a fight in a direct confrontation due to longer claws and stronger jaws with serrated teeth. If Deinocheirus could find stable habitat it would be safe for the most part it would probably face competition from elephants, some of which had a good size advantage but due to it being more semi aquatic this competition could be limited humans could also be a threat but if Deinocheirus felt in danger it could flee in to deeper water making it relatively safe for humans. It biggest predator is resource completion with its own species and possibly habitat fragmentation so there wouldn’t be that many to at any given time. Qianzhousaurus would be fairly successful for the most part would be to larger for most predators to take on and bears are omnivorous so their confrontations would be mostly around carcasses. Other carnivores like hyenas or wolves might try to steel carcasses like they do to bears or lions but they aren’t always successful in this endeavor. There biggest problem would come from humans, but even then it would not really be worth taking on most of the time. The only exception to this would be if people have domestic livestock. like big cats and bears, Qianzhousaurus would need too much food for any civilization to sustain it let alone a decent size group. Qianzhousaurus would probably get killed so people can protect their livestock from them. Any form of taming would be incredibly dangerous and rare. But otherwise would be fine since it’s at a good size to hunt most things it could catch just by itself. If Guanlong wasn’t a generalist and preferably omnivores it would struggle, a pair of wolves or a leopard would probably hunt them at the same time facing competition form them as well. If it was adaptable it would probably fill a niche similar to jackals. Rajasaurus would be like Qianzhousaurus but more dangerous for people to try to take on. It probably wouldn’t put that much competition from humans due to them hunting larger animals more often than not. tarbosaurus would probably face competition from humans when they are young but adults would be in a whole another league they would probably adapt a slower growth rate if they start specializing in hunting elephants due to their slow growth rate if not they might end up over hunting most elephant species.
Cats drove to extinction the bone crushing dogs that also probably could have killed them in direct fight. The most important question still remains which is better at efficiently catching the same prey item which may be open. As for Rajasaurus and Qianzhousaurus we do have clear evidence of Sapiens and Neanderthals hunting Mega Fauna. I don't if we have such good evidence from Eurasia but we certainly do also have evidence of human nieche partitioning but it isn't like the other option for Sapiens is easy either it is either they compete with wolves(and most mammalian predators) and Guanlong or compete with Rajasaurus and Qianzhousaurus, either way it would be hard and Sapeins would probably come out on top if they decide these therapods are enough of an issue to start going after their Juvenilles. As for Tarbosaurus humans would still be an issue when they were adult because humans also hunted Elephantids. So indicating both competition and direct conflict as options. I am not too sure about the slower growth rate maybe just higher mortality for juvenilles or their juvenilles actually out competing some of the other therapod dinosaurs in most places?. I say this because Elephant Herds can be massive, like tens of thousands during migration. While Elephants would be their preferred target they'll still be intelligent herd prey so, can organize into a wall and co-ordinate against a Tarbosaurus so I don't think Tarbosaurus would actually be so consistently successful against them. They could however change Elephant behaviour cuz lone bull males would just be getting killed so much more often.
@ Bone crunching dogs didn’t go extinct until the Pleistocene. The largest species Epycon even coexisted with cats Pseudaelurus, Barbourofelis, Amphimachairodus, and Nimravides during the Miocene. In fact North America had a mostly absent fossil record for cat and cat like carnivores for around 20 million years called the “cat gap” suggesting that cats weren’t doing so hot on the continent for whatever reason but they were still there. The genera I’d mentioned above all went extinct at the end of the Miocene probably because of climatic change rather than competition with each other. Probably due to Niche partitioning. As the bone crunching dogs were more cursorial than cats and probably operated in groups while cats are mostly solitary ambush predators. Yes but hunt animals over 500 kg was a relatively rare occurrence. Even when hunting other large predators like bears they mostly kill them when they were are hibernating. Yes while it’s possible to kill it would be too rare of an event to cause a strain on the population. There was a study that found human hunted adults horses and hyenas hunted younger animals so there was some level of niche partition. guanlong has weight estimates ranging between 100-276 lbs, large cats like tigers would have a decent weight advantage and it’s not large enough to deter humans either mix with the fact that they would be in competition with each other makes me doubt guanlong’s survival if it wasn’t adaptable. Elephants were not primary targets it was most medium to large game like deer, antelope, boars, and bovids. Elephants were at best seasonal or happenstance like lone, old or sick individuals. Tarbosaurus would be much more proficient than humans which are also at a greater risk of dying from such a prey item. Elephant males tend to be solitary and most groups are about ten individuals plus a herd of a hundred members would put an insane ecological strain on the environment it would be a rare case like wolf mega packs. Tarbosaurus would also by extension have a limited population size due to the slow reproduction rate in elephants. That or Tarbosaurus would become more generalized and by extension become smaller since it would get more bang for its buck on smaller animals.
@@aottadelsei980 Sorry, when I said cats I was referring to like Felidae not Feliforms in general. Bone-Crushing dogs went extinct after Felidae came from Asia but true, Nimravids and other American large Feliforms did go extinct before then but I think that just shows how much better adapted Felidae is compared to all other large Feliforms and Canidae but for Caninae even tho like Caninae, Bone Crushing dogs would have also been in a different niche(kinda, I don't know if there's a more specific word to use). The Argument for Humans as Megafaunal specialist hunters when we had the chance seems to have gone back and forth from a previous peak when we thought humans were the main reason most megafauna went extinct to this last generation where the argument against it seems to have dominated and opened the way for less defended but popular arguments for largely plant eating humans. But, I would say at this point wit the megafaunal argument is again strong even if not as dominant as it used to be. For example, "Mammoth featured heavily in Western Clovis diet" shows that Clovis main food source was Mammoths which also correlates with evidence of them migrating with megafauna; the structures of the Kostyonki-Borshchyovo are assumed to have been built within one hunting season which would mean something like 80 to 120 Mammoths hunted per hunting season in Ukraine during the Aurignacian which only survive the way they do due do that specific culture's rituals and Eons made this good video th-cam.com/video/VdAnC73MH_g/w-d-xo.html about Neanderthals also preferring MegaFaunal prey. And while yes, there was a preference for lone and injured Elephantids that's just general predator behaviour and hunting over a hundred of them in one season implies several events of hunting several of them at a time. Alot of Human predatory behaviors were also seasonal. The best evidence for this I know of are the desert kites of pre-agricultural Neolithic Near East which supplies evidence for massive systematic hunting of migratory herbivours every migration season. So Elephants when those were present in the area and back to the more ever present deer when those were absent makes sense; and even then humans still had a preference for larger deer and the like. With evidence of Heidelbergensis being hyper carnivorous it would seem to me that the evidence supports Heidelbergensis' descendants being the apex predators across Afro-Eurasia for a while, including hunting Elephantids but also being adaptable enough to go into other nieches when that option doesn't present itself readily and as such, have what it takes to deal with mega fauna like Tarbosaurus. That said, I still don't have an argument against them seemingly only going after Hibernating short faced bears but it does still does say something about how humans may plan against and deal with a predator that can easily overpower them when they're not prepared. Yeah, extremely large Elephant herds are rare and happen mainly during migration but Elephants becoming more migratory in order to be able to form consistent herds of up to a hundred individuals does seem like an easy adaption to deal with the sudden appearance of mega faunal predators. Also, I assume you'll see a very quick increase in size especially of bull males given how fast it took for most Elephants in Southern Africa to lose their tusks under modern human hunting. I think to some extent we would have to look to like, nile and salt water crocs for how a dinosaur could deal with slow reproducing mammalian prey but even those wouldn't be anything close to good comparisons. I can think of two things, high child morality(like before it becomes medium sized predators) and high morality again before it transitions into becoming a full adult. This second phase could be driven by highly territorial behaviour as young Tarbsaurus try and establish a territory for themselves from the older generation. So Tarbasaurus may develop to be even more territorial.
Anyways, we need Neolithic Hunter-Gatherer Homo Sapien from the Desert Kite using range (from West Africa to Central Asia) in the Cretaceous. Think of it like, real life Natives vs Skull Island.
IMO i think the Tarbosaurus wouldnt actually grow larger like you believe. I think they would get smaller in size while Velociraptors would get bigger, and they may all adapt different types of insulation, likely thicker feathers or even a fur/feather kind of thing. thats what i believe.

4:51 that jumpscares the shit out of me lmao
also id replace Guanlong with the asiatic Megaraptoran, Fukuiraptor, just for a more diversified roster of animals
7:01 that's the embodiment of going apes***
A medium Tyrannosaurus running at you at 55km is terrifying to imagine
W video I have three suggestions:
1. Could megalodon and angustidens survive the Triassic.
2. Could Giganotosaurus and spinosaurus survive the hell Creek formation.
3. Could paleoloxodon and shantungosaurus survive the Morris information.
Spinosaurus in Hell Creek would be very interesting...
@ it probably stands more of a chance than giganotosaurus
think this will affect trex, at least he has no experience with other super predators of about his own category, but most likely there will be no fights. Giganotosaurus will go east and find Alamosaurus, and spinosaurus will most likely have a harder time since there are no large fish in hell creek. Most likely, small trikes and hadrosaurs became food. large individuals either they will be out of priority or unavailable for hunting @@TheVividen
I have not watched the video yet, but one common problem I see in a lot of these scenarios that they failed to mention is that the dinosaurs of the Mesozoic were used to far different atmospheric composition to that of the Cenozoic, not only were carbon dioxide level levels four times as high during the Mesozoic at 1200 ppm, but oxygen levels ranged from 27% in the Cretaceous two as high as 35% during some periods of the Mesozoic dinosaurs would frankly have a hard time breathing in an atmosphere That is much more poor in oxygen.
in the Cretaceous period, there was even less oxygen than there is now, 21%. You may be confusing it with the Carboniferous period, which was 100 million years before the dinosaurs. There was 35% oxygen due to the fact that plants only grew on land and had a great variety. For dinosaurs, the modern era is even richer in oxygen than the native period
@ pretty much every source I can find, including several academic papers from Oxford say that during the Cretaceous period oxygen levels averaged between 27% and 30% while carbon dioxide level levels were between four and eight times as high as modern levels, which is still significantly lower than the Carboniferous period height at 37% atmospheric oxygen content, the larger oxygen content in the atmosphere in it of itself is a big explanation for why Jurassic and Cretaceous dinosaurs were able to grow to such extreme sizes
@@consulargaming3554 what nonsense it has long been proven that in the Cretaceous period there was 21%. read the articles and not Wikipedia about the large size dinosaurs are not insects oxygen does not affect vertebrates extreme sizes were achieved due to the structure
Another interesting video as always! This is actually my second favourite series on your channel aside from could prehistoric mammals survive the Mesozoic! Love seeing could theropods survive the Cenozoic on different continents. Found it quite funny having the Deinocheirus being followed by the Tarbosaurus 😂
However this episode I felt like their were some confusing absences from the roster, is Therizinosaurus technically a theropod dinosaur or is it not?
I had thought if Deinocheirus was included surely Therizinosaurus should of been there in Asia too?? Another creature I thought was missing was the woolly rhinoceros as I'm pretty sure they did reach into Asia during the Pleistocene from Siberia so shouldn't they of been in here? Thought they could of been a potential prey item if still dangerous for the Tarbosaurus etc
My final question was the pacing. In previous episodes like Africa for example we started off in the Eocene and worked our way up to the Pleistocene seeing how each mammal of that era could handle the dinosaur invasion.
I would of loved to see how Paraceratherium might handle Tarbosaurus , maybe they would of been still preyed on though if T.rex in Hell Creek could do it in their own video.
There was no mention of the Ngandong tiger either which surprised me considering it was on the thumbnail, overall I really enjoyed watching I just felt like it was sadly rushed in some areas.
I hope in the next video in this series we can see Europe and South America covered 🤞
How strong is Tarbosaurus Bataar's Biteforce
Ive seen stuff saying around 5520 psi and others at around 8,000/10,000 psi
The higher end stuff is what i see more often and consistently but idk what to think.
spears fire and traps would ensure humanity's dominance people seriously underestimate the sheer tenacity of humanity when it wants something dead aslo i bet dinosaurs taste great
A video on how non avian theropods would have affected the Mongolian Empire would be fascinating

I want to see the Mongols taking over with Qianzhousaurus😂😂
Hi Vividen!
May I ask what would be the outcome if Spinosaurus (and a few other Mesozoic reptiles, selected for the water-shores environments) would be suddenly tossed into Paleocene South America? More specifically into the dense, suffocating "Hellish Reptilarium" of Cerrejon?
My best regards to You!
dinosaurs migrated to Malaysia and Thailand at 74,000 years ago : sheeeeetttttttttt
That firs picture reminds me of GOTG when Star-lord was kicking rats around.
4:59 What’s this?
One thing not discussed in the video is a possible adaptation of Deinocheirus to consume regular plantlife, given the abundance of soft plant matter that grew everywhere. I wouldn't be surprised if a population of Deinocheirus slowly adapted to graze on the plants near the water's edge and become more generalist, further encroaching on the Chalicothere's niche. Another possible slue of adaptations could lead them to consume fish more regularly and remain further north for longer periods of time, not quite to the extent of a Spinosaurid, but just enough to allow them to compete with bears for their niche.
Very cool avian fellows on the right! 😊
The biggest issue I see for the larger theropods that you seem to have missed, is that they're likely to outbreed their new mammalian prey, and by a wider margin the bigger you get.
maybe increased infant mortality could solve that?.
@@AmachiEligwe But would it before Tarbosaurus ran out of elephants to eat?
@@Devin_Stromgren I also do think that given Elephant intelligence and herding behaviour that they would adapt to Tarbosaurus. I don't think any ceratopcid lived in herds.
Adult male bull Elephants would be in a huge bind tho.
This is the prehistoric animal version of the what if MCU
7:44 I have to doubt here because Horses too are adapted to running for long distances. Not as well adapted for it as humans, sure but which prey species in the cretaceous was adapted to run for that far, that fast?.
'Could Theropods Survive the Cenozoic?' 'I mean, they _have_ so... yes?'
Yeah...but "Could Nonavian Theropods Survive the Cenozoic" doesn't work so great with SEO, unfortunately
I feel like the part about large mammalian carnivores should have focused more on who would be better at hunting the same prey items than go would win in a fight because given their sizes they will be too much of a danger to hunt each other. Well, with the exception of the largest therapods which may actually be able to send some of those larger bear and cat species extinct but probably just a few as they generally do still have stealth adaptations.
These guys transmitted me a damn add
Biotechnarchies kinda suck :(
Very interesting video. Wouldn't a thinner atmosphere and lower O2 cause problems for Dinosaurs? Might they evolve into smaller versions?
The same factors that led to a massive die-off of Pleistocene megafauna in Asia would doubtlessly affect all these Dinosaurs for sure. I'd be shocked if any of them survive past 10kBC unless they spread to SE Asia or the Malay Archipelago.
Very noice video
Thank you!
@@TheVividen keep it up bro 👍
I actually still think it's possible for Tarbosaurus to go after Palaeoloxodon on occasion. Predators don't need to be able to defeat prey items in a gladiatorial death match to prey on them, they have tactics like ambush, attacking at night when it's harder for the prey to see, attacking animals stuck in mud/snow/tight spaces, etc. A bull Palaeoloxodon would most likely be traveling alone too. Not ideal prey for obvious reasons, but still doable. The rest of the theropods in this video, however, are most definitely going to leave adult Palaeoloxodon alone.
None of these large theropods were ambush predators which primates are most vulnerable to (e.g. Leopards, Tigers) so Gigantopithecus could literally just climb tree. It would be very easy for them to avoid these large theropods.
hmm... I didn't know Gigantopithecus could climb. I guess I just assumed given how Gorillas are mostly terrestrial I just assumed something even bigger would be entirely terrestrial.
@@AmachiEligwe Gorillas are terrestrial but are still very capable climbers. They just don't use climbing to run away from predator because their only real predator (the leopard) is a very capable climber anyway.
que gran video
Theropods are still extant, imo you should put ornithischians or sauropods in the cenozoic next.
Oh, YEAH!
2:32, I reckon its cousin Alioramus is more underrated.
Alio is in path of titans
Not really, after path of titans it's finally getting represented

Will therapods do coke?

It was going to be, but I'll be on vacation for the original release date and wanted to be here for the premiere...so I released it a week early haha
Qianzhousaurus vs dryptosaurus
The ultimate battle
Oooooh
Velociraptors would probably dominate it their niche as small ambush predators, they would probably out compete small cats. Not because they are better but because they are more likely to win a fight in a direct confrontation due to longer claws and stronger jaws with serrated teeth.
If Deinocheirus could find stable habitat it would be safe for the most part it would probably face competition from elephants, some of which had a good size advantage but due to it being more semi aquatic this competition could be limited humans could also be a threat but if Deinocheirus felt in danger it could flee in to deeper water making it relatively safe for humans. It biggest predator is resource completion with its own species and possibly habitat fragmentation so there wouldn’t be that many to at any given time.
Qianzhousaurus would be fairly successful for the most part would be to larger for most predators to take on and bears are omnivorous so their confrontations would be mostly around carcasses. Other carnivores like hyenas or wolves might try to steel carcasses like they do to bears or lions but they aren’t always successful in this endeavor. There biggest problem would come from humans, but even then it would not really be worth taking on most of the time. The only exception to this would be if people have domestic livestock. like big cats and bears, Qianzhousaurus would need too much food for any civilization to sustain it let alone a decent size group. Qianzhousaurus would probably get killed so people can protect their livestock from them. Any form of taming would be incredibly dangerous and rare. But otherwise would be fine since it’s at a good size to hunt most things it could catch just by itself.
If Guanlong wasn’t a generalist and preferably omnivores it would struggle, a pair of wolves or a leopard would probably hunt them at the same time facing competition form them as well. If it was adaptable it would probably fill a niche similar to jackals.
Rajasaurus would be like Qianzhousaurus but more dangerous for people to try to take on. It probably wouldn’t put that much competition from humans due to them hunting larger animals more often than not.
tarbosaurus would probably face competition from humans when they are young but adults would be in a whole another league they would probably adapt a slower growth rate if they start specializing in hunting elephants due to their slow growth rate if not they might end up over hunting most elephant species.
A great breakdown!
Cats drove to extinction the bone crushing dogs that also probably could have killed them in direct fight. The most important question still remains which is better at efficiently catching the same prey item which may be open.
As for Rajasaurus and Qianzhousaurus we do have clear evidence of Sapiens and Neanderthals hunting Mega Fauna. I don't if we have such good evidence from Eurasia but we certainly do also have evidence of human nieche partitioning but it isn't like the other option for Sapiens is easy either it is either they compete with wolves(and most mammalian predators) and Guanlong or compete with Rajasaurus and Qianzhousaurus, either way it would be hard and Sapeins would probably come out on top if they decide these therapods are enough of an issue to start going after their Juvenilles.
As for Tarbosaurus humans would still be an issue when they were adult because humans also hunted Elephantids. So indicating both competition and direct conflict as options. I am not too sure about the slower growth rate maybe just higher mortality for juvenilles or their juvenilles actually out competing some of the other therapod dinosaurs in most places?. I say this because Elephant Herds can be massive, like tens of thousands during migration. While Elephants would be their preferred target they'll still be intelligent herd prey so, can organize into a wall and co-ordinate against a Tarbosaurus so I don't think Tarbosaurus would actually be so consistently successful against them. They could however change Elephant behaviour cuz lone bull males would just be getting killed so much more often.
@ Bone crunching dogs didn’t go extinct until the Pleistocene. The largest species Epycon even coexisted with cats Pseudaelurus, Barbourofelis, Amphimachairodus, and Nimravides during the Miocene. In fact North America had a mostly absent fossil record for cat and cat like carnivores for around 20 million years called the “cat gap” suggesting that cats weren’t doing so hot on the continent for whatever reason but they were still there. The genera I’d mentioned above all went extinct at the end of the Miocene probably because of climatic change rather than competition with each other. Probably due to Niche partitioning. As the bone crunching dogs were more cursorial than cats and probably operated in groups while cats are mostly solitary ambush predators.
Yes but hunt animals over 500 kg was a relatively rare occurrence. Even when hunting other large predators like bears they mostly kill them when they were are hibernating. Yes while it’s possible to kill it would be too rare of an event to cause a strain on the population.
There was a study that found human hunted adults horses and hyenas hunted younger animals so there was some level of niche partition.
guanlong has weight estimates ranging between 100-276 lbs, large cats like tigers would have a decent weight advantage and it’s not large enough to deter humans either mix with the fact that they would be in competition with each other makes me doubt guanlong’s survival if it wasn’t adaptable.
Elephants were not primary targets it was most medium to large game like deer, antelope, boars, and bovids. Elephants were at best seasonal or happenstance like lone, old or sick individuals. Tarbosaurus would be much more proficient than humans which are also at a greater risk of dying from such a prey item. Elephant males tend to be solitary and most groups are about ten individuals plus a herd of a hundred members would put an insane ecological strain on the environment it would be a rare case like wolf mega packs. Tarbosaurus would also by extension have a limited population size due to the slow reproduction rate in elephants. That or Tarbosaurus would become more generalized and by extension become smaller since it would get more bang for its buck on smaller animals.
@@aottadelsei980 Sorry, when I said cats I was referring to like Felidae not Feliforms in general. Bone-Crushing dogs went extinct after Felidae came from Asia but true, Nimravids and other American large Feliforms did go extinct before then but I think that just shows how much better adapted Felidae is compared to all other large Feliforms and Canidae but for Caninae even tho like Caninae, Bone Crushing dogs would have also been in a different niche(kinda, I don't know if there's a more specific word to use).
The Argument for Humans as Megafaunal specialist hunters when we had the chance seems to have gone back and forth from a previous peak when we thought humans were the main reason most megafauna went extinct to this last generation where the argument against it seems to have dominated and opened the way for less defended but popular arguments for largely plant eating humans. But, I would say at this point wit the megafaunal argument is again strong even if not as dominant as it used to be. For example, "Mammoth featured heavily in Western Clovis diet" shows that Clovis main food source was Mammoths which also correlates with evidence of them migrating with megafauna; the structures of the Kostyonki-Borshchyovo are assumed to have been built within one hunting season which would mean something like 80 to 120 Mammoths hunted per hunting season in Ukraine during the Aurignacian which only survive the way they do due do that specific culture's rituals and Eons made this good video th-cam.com/video/VdAnC73MH_g/w-d-xo.html about Neanderthals also preferring MegaFaunal prey. And while yes, there was a preference for lone and injured Elephantids that's just general predator behaviour and hunting over a hundred of them in one season implies several events of hunting several of them at a time.
Alot of Human predatory behaviors were also seasonal. The best evidence for this I know of are the desert kites of pre-agricultural Neolithic Near East which supplies evidence for massive systematic hunting of migratory herbivours every migration season. So Elephants when those were present in the area and back to the more ever present deer when those were absent makes sense; and even then humans still had a preference for larger deer and the like.
With evidence of Heidelbergensis being hyper carnivorous it would seem to me that the evidence supports Heidelbergensis' descendants being the apex predators across Afro-Eurasia for a while, including hunting Elephantids but also being adaptable enough to go into other nieches when that option doesn't present itself readily and as such, have what it takes to deal with mega fauna like Tarbosaurus.
That said, I still don't have an argument against them seemingly only going after Hibernating short faced bears but it does still does say something about how humans may plan against and deal with a predator that can easily overpower them when they're not prepared.
Yeah, extremely large Elephant herds are rare and happen mainly during migration but Elephants becoming more migratory in order to be able to form consistent herds of up to a hundred individuals does seem like an easy adaption to deal with the sudden appearance of mega faunal predators. Also, I assume you'll see a very quick increase in size especially of bull males given how fast it took for most Elephants in Southern Africa to lose their tusks under modern human hunting.
I think to some extent we would have to look to like, nile and salt water crocs for how a dinosaur could deal with slow reproducing mammalian prey but even those wouldn't be anything close to good comparisons. I can think of two things, high child morality(like before it becomes medium sized predators) and high morality again before it transitions into becoming a full adult. This second phase could be driven by highly territorial behaviour as young Tarbsaurus try and establish a territory for themselves from the older generation. So Tarbasaurus may develop to be even more territorial.
nice
Anyways, we need Neolithic Hunter-Gatherer Homo Sapien from the Desert Kite using range (from West Africa to Central Asia) in the Cretaceous. Think of it like, real life Natives vs Skull Island.

Hahahahaha tarbo shit talking deinocheirus that fraggin guy
1:39 tf2 mentioned
IMO i think the Tarbosaurus wouldnt actually grow larger like you believe. I think they would get smaller in size while Velociraptors would get bigger, and they may all adapt different types of insulation, likely thicker feathers or even a fur/feather kind of thing. thats what i believe.
Yay tarbosaurus!!!!
I wanna see a Tarbosaurus fight against an Asian Elephant
