Imagine running into a lion that could look you in the eyes from eye level!
You can! Look up the liger or something. Lion and tiger mix.
I'd rather not, actually ._.
I think "running away" is more apt
Awwwww.... kitty katty!!! How sweet 🥰
@fireyf
It's not their eyes I'd be concerned about - I'd be more worried about seeing their teeth at eye level.

@2:51 - I was confused about the mention of horses as possible prey because I had read horses were introduced to North America a few hundred years ago by the Spanish. Turns out they were in North America before that but went extinct on the order of about 10,000 years ago.

Ya know, I was thinking there was something missing here in North america.
apart from peace? yeah probably
Like something that hunted bison and other big ass animals like lions do in Africa right?
@@Anthony_Diaz1904 Yes
Look up "evolutionary anachronisms" then. It's an intruiging topic. There are lots of ecological processes that do not function well without the extinct megafauna, and lots of species that still depend on megafauna and their ecological services. For example many of the wild ancestors of fruits and vegetables exploited as human food today suffer from the so called "megafauna dispersal syndrome" with examples including gorse (wild pumpkins), melons, cucumbers, avocado, pawpaw and many more.
We're also missing camels....
Holy crap, why am I only now hearing about these things? You'd think such an impressive creature would get some mention in documentaries about prehistoric life, but it seems like anything with giant fangs or tusks hogs the spotlight.
I've read that Native Americans lived with these things and quite possibly killed many of them

Extinct around 11000 years ago. Even if they had survived, we would have had the same episode today with Hank telling us that humans killed them all in the 18th century for sports instead.
Nice alternate history suggestions
Or white women from Norway would have bred with them creating a race of thundercats! Thus, surviving the ice age...
One wonders if there are Native American legends or artwork involving lions. The Choctaw have stories that stretch far enough back that they include mammoths or mastodons. How they are presented in myth or art by cultures whose ancestors actually saw them alive would be extremely instructive in how they may have lived. Most scientists are reluctant to believe in “folk memory” or indigenous mythology but many times it has proven to be extremely accurate and sheds real light on ancient times.
Honestly I can see some genuine scientific value in this. Maybe people should ask them some time.
Yes, this sounds like a good idea! They should ask. In the old stories can be details.
Wouldn't surprise me as for 2022 there has been many lies told about the History of the entire American Continent... Such as the many civilizations found in the Amazon. That where advance like Rome or Greece.
Listen to Graham hancock he has amazing stories about the Americas
Lions weren't far enough North and West to survive the Younger Dryas, and then migrate back onto the continent, along with the current indigenous peoples, like the Choctaw. Who arrived after the event.
@@kirkjones9639 more and more evidence shows the clovis people weren't the first ones in North America

@@billylauwda9178
Welp, I've got my next projects planned.
*mad scientist laughter*
I wonder if their extinction was due to their prey dying out. Something that large needs a big payoff for the hunt. Having to go after smaller, more agile prey may have done them in via starvation. They expended more energy hunting than they got from eating it.
yes thats fits in very well because every continent prior to 11,000 years ago was very alike to Africa and in some cases like North America and Sundalands even more impressive having beasts like the 1000lb American Lion and Ngandong Tiger. It may also be that they heavily underestimated the strength of humans because we migrated from Africa and have no knowledge of how to defend themselves from us and our ingenious weapons. Thats why Africa still has most of its megafauna left because we evolved alongside them and new of the danger we proposed, its why not only carnivores but even large herbivores like elephants and rhinos who a unarmed human poses no threat to still either chooses to run away or attack us. Probably Mammoths saw us as some strange harmless animal who they payed no heed to allowing us to get very close and attack them and these Lions too saw us just as easy prey when equipped with fire we are not.
Pretty much. Just like the Short faced bear, Megalania, Dire wolves, Megalodon, Terror bird, Sabre tooth cats, etc strictly needed megafauna to uphold their strength to maintain size and power.
I dont believe in that theory anymore.. ever heard of Graham hancock there are other teorier out now that are actually a bit more trueworthy...
@@cbp117 Graham Hancock is just that a cock, always chatting a lot of waffle.
The Jaguar has made a resurgence in the South/Southwest even though most states will not recognize this or any population of “Black” Panthers/Jaguars/Cougars/Pumas/Mountain Lions...
What do you mean most states won't recognize this? I know at least Arizona does
I know Colorado isnt exactly "South/South West" but its common knowledge that mountain lions live here and will eat your cats and smaller dogs. Even down into the foothills along the Front Range news stations will report on sightings and attacks.
Despite decades of reliable sightings, photographs, trail camera images, scat, and track castings, Michigan DNR denied the existence of cougars until one was killed by a car and the corpse was publicized. Then, it was purported to be a wanderer from the western states. Even evidence of breeding pairs was ignored.
@@mred8002 Cougars are elusive and some can wander quite far. It's not easy to confirm presence of a resident population when a few individuals recolonize an area the species was previously extirpated from
@@Somethin_Slix Fellow Coloradan can confirm.
The american lion wasn't the only giant lion around at the time, a specimen from Natodomeri Kenya is believed to be a giant lion rivalling even its American counterpart.
What is it called?
@@dagodlypug2399 There hasn't been a designated scientific name but it is referred to as the Natodomeri lion and the specimen number is KNM-ND 59673.
@@biglil771 Yeah I heard it too. Its a giant specimen and are actually from the same DNA as African Lions but much bigger
@@biglil771 do they know the full length of the skull
@@21LAZgoo The Natodomeri lion had a basal skull length of +380mm at minimum and since the condylobasal skull length is normally 25-35mm longer than the basal length an estimation of +410mm for the condylobasal length would be reasonable and thus the full skull length would probably be +460mm making it equivalent to the largest cave lions both in America and Europe.
They've extracted DNA from them? You already know what we gotta do!
Life, ah, finds a way.
Make a Jurassic Park reboot with prehistoric mammals instead of dinosaurs? Yes, I agree.
@Dan Ryan LOL!
I was going to suggest bringing them back to life and releasing on the Great Plains. My son is disappointed that I wasn't going to make catgirls. I've forgotten what it was like to be fifteen years-old and 90% hormones.
Cat girls is that not what we're talking about
When Short-Faced Bear was brought up, Jurassic Fight Club sprung to mind.
It was a great video. I wish they would produce a new DVD I've watched that one more times than I can count ...enjoyed it every time
2020 can’t get any worse!
November: *Breaking: Giant prehistoric lions spotted all across america*
I'll be honest, that wouldn't be worse, that would be awesome. Course I've got a literal ocean between here and there so I'm probably underestimating the problem.
I'd rather get tiny sized pterosaurs though.
I want the Tarpan or another truly wild horse. Przewalski horses are most likely domesticated to some degree too, so there are no truly wild horses anymore... Also the elephant bird and the dodo.
@@solar0wind I mean, zebras and asses are technically horses too. We like to label any extinct Equid as a "horse" (e.g. Eohippus is commonly referred to as the "first horse"), but for some reason we always think of zebras and asses as separate from horses, even though all living Equids are literally in the same genus, Equus. I know what you mean though. Honestly, any extinct species would be awesome to see alive and in the flesh.
You think that's weird....I saw a cat snuggling a dog and spaghetti monkies playing at the play place the other day.

@@virglibrsaglove but there are Ligers which is the biggest cat in the world.They are hybrid of Lion and tiger weighting upto 400KG
My hypothesis: They overheated. Being big is good when the weather is cold as you conserve energy. When the weather warms up you have real difficulty keeping cool.
Maybe except most really big animals (rhinos, elephants, hippos, etc.) are found in warmer climates. Animals on a species level don’t simply overheat and die (although certain individuals might), rather they change their range in response to temperature changes. With that being said, most of the areas that American lions were found in (such as California), had similar temperatures or were actually warmer during the last ice age! American lions were much more temperate to warm adapted than cave lions, hence why you find them in in California and cave lions in Alaska (in a similar vein, dire wolves were also warmer adapted and not found north of southern Alberta)
And they still should be in places like Alaska or maybe Canada.
Nope, most like related to human activity.
It's not a surprise most megafauns went extinct right after humans arrived on the continent. Humans were too OP even in the stone age.
@@apathak34 I think its because American lions were specalised towards the very large megafauna species when those disappeared so did the mega predators. Jaguars and Cougars survived because they are more generalize and can comfortably prey on more plentiful medium size prey like deer
@@RocketHarry865 Yeah that makes sense
Imagine the litter boxes...
@christopher snedeker starts excavator engine.
0:46 Took me _way_ too long to realize that wasn't a 5-legged Lion but two Lions side-by-side
LOL. Meanwhile I didn't even notice there were 2, I was too focused on the size.
Recent studies show Homotherium (about the size of a modern lion) and Smilodon both had social tendencies. Btw, found quite a few atrox specimens in my Ph.D. Also, you’ve missed the existence of the large Ice Age jaguar, Panthera onca augusta. Also, the sabertooth cats had a larger South American variant, Smilodon populator. In terms of extinction theories, you’ve missed some viable ideas.
Nice to see Hank’s enthusiasm, really added to an already interesting video

Episode idea? What animals were the first to make vocal sounds? Hearing birds and dogs as I walked to the bus stop made me wonder how long animals have been communicating vocallu
Probably before animals even left the water, a number of fish can make loud gruntss using their swim bladders for example, but I'm afraid I can't say anything more definite than that.

Very informative. I live near the La Brea Tar Pits, so it was neat to now feel more knowledgeable about the area. Thanks!
Can you imagine having a house cat that big?

Cat: Nope
Me: Okay then.
Now I want to cuddle one!
@@KSWfarms Me, too! Assuming they would be okay with that! 🦁
If these were still around I'd probably have them as my favorite of the cat species. Since childhood its been the Tiger though, the largest and most powerful of the cats and they look the coolest too. With Cheetahs being close second. But a giant felid that would be eye level on most adult humans? Thats terrifying. All cats are engineered to be masters of ending lives. Make it a giant like this thing and you have yourself a really large problem.
If you find tigers interesting check out the extinct Ngandong Tiger who lived in the now submerged Sundaland and went extinct around 10,000 years ago. It weighed in from 350-400kg with some upper estimates over 500kg. Would of more than rivaled the American Lion and hunted elephants and rhinos singlehandedly.
Super accurate and informative video, thanks so much and congratulations!!
Not really accurate considering mammoths did not disappear 11000 years ago and were actually found to have existed as early as 3800 years ago on wrangel island
@@SuperBubbleduck You are right in this. But those where dwarf mammoots, not regular ones:)
@@andersonboy620 They are still mammoths
whether dwarf or south American its still "a regular one"

Great video.
they werent 523 kg, that has been proven to be a complete overestimate, the largest specimen ever found which had a 18.4 inch skull is 372 kg
Time to "Jurassic Park" them back into existence.
Could you do isotope analysis on the bones? Their prey would eat different things, so that eating mammoth meat would have a different ratio than ground sloth or wooly rhinoceros.
Great content! Subbed for my kid.
All I can think of is that if these were somehow still alive, there would be someone crazy enough to ride one.
Were there ever marine marsupials and how do they know a marsupial from bones alone
To the best of my knowledge, no, there's never been a marsupial we might call a proper marine animal.
If it serves any, though, the originally named water opossum is semiaquatic, adapted to a point you could consider it a land-focused otter.
Males of the species have pouches, and they use them to hide their genitalia while they swim. I think that's hilarious.
@@nulllex0099 hahahahah!!!! That's wonderful :) thanks for the info!
At least none that has been found yet. Just wait until a giant platypus fossil is discovered.

Wild Siberians never get up to 660lbs. The largest one ever hunted was 620lbs.
@tigerLuver Amur Tigers in Captivity have a higher chance to grow bigger and gain more weight than Amur Tigers in the Wild where large prey is *VERY HARD* to come by...
@tigerLuver not the biggest Siberian Tiger ever found was 8362571625287 lbs and hunted Megladon regularly
The statement "Try to learn something from the past, while having an extinct extraordinary creature as an object" is not wrong. But sometimes it feels like "Trying to learn an extinct extraordinary creature, and hopefully it gave some information about the past".
When you type gigantic like the title of the video it looks like this:
*GIGANTIC*
Before I learned of the actual size of the American lion, I had created a species of felid for a story I'm writing. This felid is described as being 5'0" (150cm) tall at the shoulder and 6'0" (180cm) tall at the crown of its head.
Is this is what we call an AW LAWD HE COMING

If there's one thing I learn when watching ancient history, everything was bigger back then. From rats to cats to sloths all of the them were HUGE.

It would break your spine with 1800 psi preassure, that is around 80% more than Bengal tigers. But it is still an idea. I want to hug them to. I want to know touching one of the biggest cat ever feels like. But most likely we will never know...
This species shares so many physical similarities with the jaguar scientists thought it was one.And then there's "mesembrina".
Man an American lion pelt would look so good in front of a fireplace
There is evidence that smilodons (saber tooth cats) were social. Paleontologists found bones with healed breaks. This can only happen if other cats took care of them while they were healing.
I can see that. They were all smiles... All men could do was smile back.
😂😂😂😂😂😂
Surely a big reason why big cats died out is humans.
Along with all the other Mega-Fauna, and as it so happens most humans, at exactly the same time?
I personally have a problem with the idea that humans killed off all of the mega fauna. I can't wrap my head around the idea that the scattered tribes of the time could hunt that many large animals as to drive them to extention with the technology/craft available, imagine hunting a mammoth with a flint tiped spear. Environmental factors IMO had to be the main force, granted humans didn't help matters.
@@tauneutrino1able If they were already declining because of a changing climate, then yeah, humans could have pushed them over the edge. I also wonder if there's evidence of humans killing mammoths the same way they would do a buffalo drive, where they'd stampede a herd off a cliff - killing far more animals than they could use.
@@lyreparadox I'm sure that they did do cliff drives but I would contend that it wouldn't be in large enough numbers to make a big difference. There wouldn't be the "commercial" drive to slaughter the larger animals in large numbers to justify the dangers that would accompany hunting them. Food would justify a hunt but how much could they be eating back then don't see them killing 100 animals in order to eat 1. So it would have to be the environment unless humans were heavily predating on the very young animals.
Edit. Not arguing just expanding my thoughts a little bit as much for me as anything else.
It's virtually impossible humans killed off several of the largest species in North America at that point in time. Look up the Younger Dryas Impact Theory. There's plenty of evidence for it.
Epic mount.
I can't imagine the cat box cleaning!
Do a video on Wolverines!
I guess this lends new credence to the idea that everything is bigger in Texas.
I love lions😍❤️. My favorite big cat.
I got fed up with excessive ads on UA-cam and now use an ad blocker. So much for Google doing no evil. They're ruining UA-cam so they can become even richer. I must say that Scishow does ads right. The idea isn't to annoy or interrupt or interfere with a program. A proper ad should be well placed and introduced. Good job!
My favorite supersized lion is Aslan. Biologists have found little evidence of his social habits and not much is even known about his physicality. After all, it's not as if he was a tame lion.
The Younger Dryas Impact Hypothesis makes the most sense for the mass dying at the end of the last Ice Age.
I don't think so, otherwise the Megafauna of Cuba would have been extinct too
How far south did American Lions go? I read in Zoobooks as a kid that they went into South America as well
"big brain doesn't mean social..." Yeah that explains my solo friendless lifestyle

@KAHANU ERMEYAS-TULU Which hasn't stopped a recent publication from suggesting that Patagonian jaguars were American lions (in spite of prior genetic analysis in favor of it beign a jaguar).
@KAHANU ERMEYAS-TULU If you actually seat down and read the comment thread, you'd notice I was actually taking shots at the hypothesis.
Did you seriously think I'd put more stock on histology based phylogenetics than a phylogenetic study based on actual genetics? :D
@@miquelescribanoivars5049 it's a lion it's not hard to accept facts!
I think I read somewhere that the North American populations of cougars and jaguars did go extinct at the same time as the other North American big cats, and the South American populations re-colonized North America later.
Every scishow video is kinda like playing Russian roulette. In stead of a gun with bullets, you have a video with Hank.

Thank Goodness !
Could you imagine how many people would come up missing or be attacked. Would not be all of this hiking through the woods or camping
Or even worse they could eat corpses of a killer's victims making it looks like the victims were attacked by them instead of being murdered by someone
Thanks for adding pounds as well as kilograms.
During the Younger Dryas, most everything over 55 lbs. went extinct on the American Continent. The American Lion came in at around 850 lbs. or so. Not much of a mystery there. Humans also became extinct, in the area at that time also.
So lack of water then? Sorry it's not obvious to someone new to the topic.
@@Sara3346 A cosmic impactor struck the Earth, just North of the Great Lakes region, and this caused a sudden, short ice age. It lasted from around 13,000 BC to 10,000 BC. Scientists call that period in history the Younger Dryas. It is why North America doesn't have the large mega fauna, like Africa. Big Cats, Dire Wolves, Mammoths, Mastodons, Flat Face Bears, Camels, Horses, Humans etc., all became extinct, on the continent.
@Amos Zahirovic So?
@tigerLuver an American Lion is much bigger than the biggest Liger in height and weight and Ligers are already much bigger than Siberian Tigers not to mention these extinct Big Cats would have been more powerfully built as they hunt Ice Age Megafauna and frequently compete with the Largest of all Extinct Bear Species over carcasses, Also recent studies classified the American Lion as a Giant relative of the Jaguar and placed in the genus Jaguarius.
The american lion is a subspecies of the well known Panthera leo, it's not a jaguar despite being closely related.
