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.

Apparently this animal had the proportions of a Grevy's zebra without the big ears.

Im in the Horse God camp. I want to believe a genetic freak was preserved for us to find

Saying dogs had more of an effect on humans than horses is quite frankly BS

I had Clydesdale horses years ago and their power was incredible. Now imagine a wild horse this size with the aggressive temperament similar to a zebra from having to contend with the various ice age carnivores. It must have been extremely dangerous.

They would almost certainly target large theropod eggs and drive them extinct rather quickly as that's more or less what hominids did to all large predators. Hominids wouldn't take a single egg or a single nest like most egg stealers would they would ravage entire populations and use fire to force the large animals away from those nests. Between egg theft and the increased competition for medium and small game hominids would very quickly shape the ecosystems to their liking.

It’s “horses.” Apostrophes don’t pluralize things.

Sounds like a real champ! Thanks for the killer video 🙏

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.

Horses are some of which called "Adroit'' creatures❤

They were hunted by Deerbras

There were 4 natural variants of wild horse in Eurasia: - The Przewalski in northeast Asia, that you already mentioned - The Tarpan in northwest Asia and Europe - The Northern Forest Horse in northern Europe - The Polar horse in northern Asia (further north than both the Przewalski and the Tarpan) Except for the Polar horse they are all recognised as separate ancestors of modern horses and have their own scientific names. Tarpans were the first to be domesticated about 6.000 years ago in the region between rivers Dniepr (now Ukraine) and Ural (now Russia). They existed in 2 variants: Forest Tarpans (Europe) and Steppe Tarpans (West Asia and Central Asia) and are the ancestors of the early domesticated types 1 (resembles an Exmoor pony), 3 (Akhal-Teke, still present) and 4 (Caspian horse, still present). Domesticated type 2 is a hybrid between Tarpan and Przwalski (Mongol pony, still present). The Brothers Heck, who were in charge of the Hellabrunn Zoo in Munich, recreated the Tarpan and the aurochs from primitive horse and cattle breeds in the 1930s, so there is sort of an artificial Tarpan (aka "Heck horse"), that is often kept together with artificial aurochs (aka "Heck cattle") in wildlife parks. But there are also still horses, that resemble the original Tarpans very closely. The Polish Konik horse is most likely a surviving population of Forest Tarpan, and the Russia Vyatka horse is an only slightly modified Steppe Tarpan. Domesticated type 1 also still roams Europe in many local variants, whether it's the Exmoor pony, Fjord horse, Sorraia, Skyros pony or Estonian hobune. These are primitive pony and small horse breeds, that were directly formed from Forest Tarpan stock. The most well-known pony breed, though, the Shetland pony, is not a Tarpan descendant, but a miniature Northern Forest horse. This original horse variant is the ancestor of heavy draft horses (and the smallest, yet strongest pony). The Polar horse is also still around: It's now known as the Yakutian horse now and survives some of the coldest temperatures on the planet in northeast Russia. There's speculation, that it may have influenced Asian breeds, but apparently it hasn't been thoroughly researched yet. So let me correct you from the sidelines: The Przewalski horse wasn't and isn't the only natural wild horse population. At the very least you have to count the Yakutian horse and the Konik as surviving Polar horse and Forest Tarpan. And as the Shetland pony is essentially just a Northern Forest horse, that suffers from insular dwarfism, add that one, too.

Love this!

How do you know all of this. Like sure little evidence, geography, and speculations. But again, I would have never been able to explain what the heck happened or was happening all those millions of years ago, just crazy the way you perfectly explained all of this!

Biggest crocodile ever lived on planet Earth. ❤❤❤❤❤ It was trex of water.

Horses have had a much, much, much bigger impact than dogs. It's not even questionable. More people may have dogs, and maybe we.have emotional attachments to them, but how did they change the course of humanity? Helping with hunting a little? Horses radically shifted the course of humanity - just look at what happened to the Native Americans after they got the horse. Horses are the reasons we were able to populate America, they plowed our fields, they led us into war, they hauled out firewood to keep warm - humans are still living in the stone age without the horse.

Good god, how would someone even ride that thing? You’d feel like a little kid sitting on the back of a draft horse. Not so much piloting the horse as just being along for the ride.

That explains Raol’s horse from hokoto no ken

Chalicotherium is the most weirdest horse for me.

Missed out the Filfla shark of 1987 - largest ever recorded at 23ft.

OK that makes sense....everything was huge and so were horses.

Octopus eyes look so cool

Titanic??

What is a Duraft/Diraft Horse? Is it like a Giraffe Horse? Hahahaaaaaaaa.

Is it bad that i hope they find one frozen somewhere and CLONE IIIITTT. They are trying for Mammoth, why not Eqqus Giganteus?!

This was a cool and interesting video. You know what I would find interesting, the evolution of the Wildebeest.

Could it be that these teeth belong to a species of Giant Ass instead?

What about Shadowfax - Lord of Horses?

I think if humans could establish a perimeter and have some kind of society they would stealth and hunt certain species to extinction. T-rex newborns could be a great source of food. Their parents can be trapped while coming to save their newborn. They could set on fire entire habitats. Humans are a nasty species because they can manipulate the environment and have tools. I think if any of these current apes start to build huts we already feel we have competition.

they were called Titanoarbora, horses as big as a tree, and they were used to farm massive sequoia, this was right here, I'm in North Idaho, a very very long time ago, and a not too far long ago, both!

04:09 this is where you dropped the ball. Up to this point you gave measurements in normal units as well as those weird half british/half whatever units. 3000 whatevers mean absolutely nothing to 195 out of 197 countries.

Be helpful if the size of the various horses were given in hands, like we still do today

Correction, the Przewalski's horse are not true wild horses. They traced their DNA back to the Bow-tie people. The last true wild horse was the Tarpan Horse that went extinct a long time ago

I read that DNA tests on domestic horses from sites from a bronze age nomadic culture leads scientists to hypothesize that ALL "wild" horse populations are actually feral

I read about , Forest horse's , years ago and it said that they where giant ,larger then any horse , now living . Always wished I could have ridden one or at least been able to see one. I wonder how my fantasy of them would compare to their reality , their true form ...

My first viewing of your channel. Quite a good video, I might need to subscribe.

Nice video man! Video idea: Can modern day humans survive the age of dinosaurs? Keep up the good work!

Samson was big like them

5:53 Thank you for “robusticity” rather than the regressive “ness” . An additional reason I have subscribed! Keep it up!

Rats will decently do well

I know there were giant camels

RIP orcas. Seriously, we already know megalodon ate orca-sized raptorial cetaceans…

A 3,000 lbs wild horse would be quite formidable. I’ve handled a few different draft horse breeds. They are usually very gentle with people, but can easily hurt or maim you completely by accident. The younger geldings would spar behind our barn sometimes and would shake the ground hundreds of feet away. We could feel it inside the house!

What an amazing possibility, imagine ? Thx. 👍

I want ride that horsey

Giant horses are still here today wth

Gorgeous tributes to the loves of my life. Thank you for a truly unique and wonderful tribute.

nice

Equus Giganteus (the "Giant Horse") lived through the Ice Age's in America and was predated on by large extinct carnivores such as the American Lion and the Giant Short-Faced Bear, these giant horses went extinct 12,000 years ago around the same time as many other N.American megafauna went extinct. After Equus Giganteus extinction, horses would not return to the continent until Westerners re-introduced them nearly 12,000 years later. Equus Giganteus weighed around 2600-3300 lbs. For comparison, the typical weight of a modern day racehorse is around 1100 lbs. The largest ever horse recorded in the Guinness Book of Records was a shire horse which went by the name Samson (later renamed "Mammoth") and lived during the mid-19th century, it weighed in at 3,359 lbs (so comparable to Equus Giganteus), you can see a picture of it next to people. Their size may have made them too dangerous for people to try taming, especially if their temperments were anything like that of wild zebra (very bitey animals) or aurochs (said to be naturally aggressive towards humans). A lot of people aren't aware of it, but also stallions actually have a pair of canine teeth concealed inside their mouths which they use to inflict devastating flesh ripping bites on their rivals, you can see the horses canines and "wolf teeth" on it's skull anatomy. A potential bite from one of these giant horses would simply not have been worth it, let alone a fall from one (broken bones) or kick (certain death).
