- Cats vs Dogs - a debate as old as time itself. Unfortunately for dog lovers, felines always seem to have the upper hand when it comes to size. But once upon a time there was a dog that could give even the big cats a run for their money. Meet the Epicyon, the lion sized, bone crushing canine of North America.

Who's a good boy. You throw a stick and it brings a tree back.
My German Shepherd does that, not just a limb but the whole damn tree.
it brings a lion back 😂
@@emiliospowerballer1441 It's not killing a lion lmao
or Volkswagen beetle
😂😂😂
It's terrifying that its bite force was similar to an Alligator.
Yea I work with some pretty big dogs everyday and you have to be careful. Bite is always worse.
Considering their teeth, it's pretty obvious that they could straight up rip limbs off with one bite
Not to mention being SHOULDER HIGH to Danny Devito!
@@megawl2086They didn't have retractable claws so I guess their deadly jaws made up for it
@@chubbycheeksgirl If I'm not mistaken, Epicyon had paws that were to some extent similar to those of a bear, in theory it is the only large canid that could hold objects with its paws. Since it is theorized that they used it at some level to hold their prey. But there is a lack of depth to confirm this hypothesis or not.
Danny Devito should be the size comparison in EVERY text book
I vote for Frodo Baggins.
The Canadian Timber Wolf, also known as the Mackenzie Valley Wolf or the Northwestern Wolf is recognized as the largest wolf in the world. Weighing up to an astonishing 175 pounds (79.4 kg) and measuring up to 7 feet (213 cm) in length. It is a subspecies of Grey Wolf
My friend had a Timber wolf that weighed 220 lbs. Of course it also laid in front of an ice chest full of dog food and would eat for like 15 minutes. It was obese for a wolf. One time we put shorts and a Tshirt on it, it went into the road and started howling right when the animal control officer starts driving up. He laughed so hard, then it shit its shorts, he laughed even harder and drove off saying your on your own.
It's interesting when he's not even the gray wolf subspecies in the story.
Wood Buffalo Park, Northern AB has the largest wolves in an isolated area. They’re specialized to hunting bison in the wooded areas and MASSIVE. Wolves outside the park, while still huge (especially if from the park) but further away they get smaller.
Many of these records are reports or are kept in zoos, where they usually get even bigger. The genus canis in general for many years there has been no record in nature of such large specimens. Today the greatest find in Nature is the Chrysocyon brachyurus Maned Wolf from Brazil, they are very rare to be seen, but huge, already being seen Specimens measuring 1.90 m (height) are more than once found in nature, and there are barely any specimens in captivity. Even if caught for treatment, they are then released into the Brazilian savannah. People tend to forget about him since he is the only one of his kind, but he is a Canis

You otter do a video on Enhydriodon. The giant otter, Enhydriodon, is the largest known mustelid to ever exist, weighing around 440 lb (200 kg) and measuring over 9.8 ft (3 m) in length. They lived at the time of Australopithecus.
Jesus Christ, a lion sized mustelid, no predators today would stand a chance. I put my money on a mustelid any day, if they fight an animal their own size or even bigger. Unless it’s a 700+kg bear

This channel uses the best thumbnails! The pictures used to depict species are always high quality & reminiscent of hand drawn art back in books in the 70's. Amazing effort!
I remember being in detention back in the day and seeing all the hand drawn dinosaurs and ice age animals in those old books
FYI: mountain lions range considerably east of the orange on your map. They are more and more common all across Oklahoma to Arkansas and Texas. I've seen them myself and my family members no longer hunt alone after a petite aunt realized she was being stalked.
Great channel. Subscribed.
I agree. We have caught a few on trail cams on the northern edge of Lake Sam Rayburn in deep East Texas. Locals have sworn to see them back into the 1990’s but we finally started getting pictures around 2015.
@@cheeksfadays6322 I first saw one in 1979 or '80 in a heavily wooded area NNE of OKC. By 2000 my family in southeast Oklahoma were seeing them as well as more sign of bears. Now, 20 years later, they are pulling alligators out of the lakes down there. (I don't camp out any more.)
Periodic reports in Michigan's UP.
I've lived in Oklahoma most of my life and never seen any cougars. I never saw any when I lived in Colorado, Arizona, or Washington, either.
have them in ontario, canada as well.
What do you call an Epicyon with a PhD in Paleontology? "Dr. Bark," the expert on prehistoric bones, who believes every dig site is just a game of fetch waiting to happen. 🤭
Quit eating the artifacts, Dr. Bark!!!!

Omg the comment section is filled of hilarious Canids jokes haha
Why does the map at 0:57 indicate South America with no canids? Maned Wolves, Bush Dogs, Short-eared Dogs, and seven species of fox call South America home.
Same with Australia, DINGOS !!!
@@liamcarter4818 Not a native animal. Arrived some 6000 years ago thanks to humans.
I guess it just shows the Canis genus?
@@KaiserToons the narrator was discussing the family Canidae and the map includes graphics for the African hunting dog (genus Lycaon). So, no. Just a big boo-boo.
@@JohnDrummondPhoto true.... but the map he was showing only appears to correlate to Canina, a subtribe of canidae. en.wikipedia.org/wiki/Canina_(subtribe) so maybe when he was doing research he grabbed the Canina distribution instead of a general Canidae distribution map?
On a side note, today I learned the timber wolf and red wolf are not sub species of the grey wolf. :)
5:50 i want a video dedicated to THAT thing
@@Sirdilophosaurusthethird2.0 shut up troll
That's not a dog...
*THAT'S A DAWG*
😂
Imagine these fighting massive prehistoric WOLVERINES! The Megalitis ferrox is another supersized mammal that lived over 5 million years ago during the Miocene Epic and weighed up to 264 pounds, albeit in Africa.
@@Sirdilophosaurusthethird2.0 indubitably
Mustelids are New World, including M. ferrox, North America. The Old World convergent counterparts were Viverrids.
Epicyon would have been a spectacular sight to see if it were alive again
I would say a epic sight to see lol.
I wanna see them fight lions, good luck lion fighting a 16,000 newton dog that can weight the same amount of pounds as you. You’re basically fighting a crocodile dog.
@@S.F157 I'd like to know the outcome without them actually having to fight.
@@S.F157the lion on average weighs much more than what the Epicyon Haydeni did. The 370 pound one was the largest estimated size of Epicyon Haydeni, most individuals weighed much less than that. And the largest lions weigh way more than 370 pounds.
And having a huge jaw bite force alone wouldn't be enough regardless, the lions have claws to it's advantage and would most likely be quicker and more agile than the E.H, not to mention stronger...
@@harsha1989able actually if you check out the Validus (large Haydeni Specimens) they weighted around 181kg or more so basically 400Ib pounds. They were evolutionarily getting bigger if you check their fossil record. They were also as robust as a grizzly bear, which is pretty robust. They were not built like average canids (Modern Canines). These were dogs that were built like big cats.
Also if your jaws can produce a bite force as strong as a saltwater crocodile, that’s something to be fearful of as another predator since if you get bit you can risk injury, which will decrease your survival.
A 100 pound weight advantage doesn’t matter to an Epicyon Haydeni, these things fought carnivores far more dangerous than modern lions like Amphimachairodus or Huracan which were more dangerous competitors of Epicyon. The Borophagus were also another competitor that could have dominated Epicyons over carcasses at times like modern hyenas.
Was that Danny Devito? Lol I approve
This animal (and other large, derived borophagines) was long assumed to be a scavenger, based on the assumption that hyenas were scavengers; obviously, hyenas are actually predators, and Epicyon is now widely recognized as such as well. However, this doesn't mean the popular view of this animal meets the fossil data. Large borophagines are often assumed to have been ambush predators due to their size and the fact they supposedly had grappling limbs, part of the reason the assumption of them being outcompeted by cats took hold, However, while earlier large borophagines like Aelurodon did have some grappling capability, later ones like Epicyon did not. Their forelimbs were more flexible and mobile than that of canine canids or hyenas, but nowhere near as flexible or mobile as the grappling forelimbs of cats or bears, and their feet are relatively small and have small, blunt claws for running. And while Epicyon was bigger than any other canid, it still wasn't the 170kg monster it was often assumed to be, and other large borophagines were more in line with the sizes of large, cursorial predatory canids alive today, meaning that they wouldn't have been too big to run down prey (not to mention that bears are even less suited to running and can move terrifyingly fast for a surprising distance). Therefore, it's actually more likely that derived borophagines like Epicyon were pursuit predators, relying on their jaws alone to pull large prey to the ground.
The dying days of the late miocene brought an end to Epicyon and the dominance of borophagines, as the climate became cooler still. But one derived borophagine- Borophagus Diversidens-managed to squeeze through, and remained successful throughout the next epoch, the Pliocene.
Well, it did share its habbitat with the biggest bear-dog species ever, Amphicyon ingens, which was not just larger than it, but much, MUCH larger, the size of a grizzly bear... While it was capable to hunt, certainly, its ability to crush bones certainly came in handhy, as it could at least part of the time scavenge the remains of the Amphicyon kills for the nutritional bone marrow that bear-dogs could not access.
Borophagus Diversiden can weight up to 200+ max. Aelurodon Taxoides around 140-150. There were other Borophagines as well that took different niches.
Epicyons were also evolving to get larger so who knows what their final form would be like.
0:35 DAMN!! 😮
Kitty said, "Tastes like Chicken!!"
🤣
That jaguars for you. The baddest cat on earth. Fights and kills caimans even under water
I'm very impressed with your production quality.😃👍
Another awesome video. Just discorved your channel, and I'm loving it. Can you at some point do a video about Jaguars and Leopards, two of my favourite big cat species.
10/10 I'd still try keep one as a pet if they were still around.
good luck with that ,
They would have to be domesticated first. They would be way more harder to domesticate than it was with wolves...
It would never be domesticated. It's more like a hyena and a wolf. It would just be a wild animal, but both could be tamed under the right situation, but it will never be your pet. You can handle them, but you will never own them
@@freetheworld12it’s honestly would be simple as taking one as a baby
@@Mikey-wf9pyyou could definitely domesticate ts it’s a dog if you get one when it’s a baby ur going to be fine it’s literally like the first dog I was thinking about riding ts like a 350 pound dog probably toping 25mph for short periods on time
Imagine the size of a medium Lion, but the smarts and pack mentality of a Canid.
So a medium size lion?
Don't the lion members of a pride already do that today? Members cooperate with each other & strategize during a hunt. They use a chaser lion or two to cause chaos & confusion in the herd to recognize & isolate the weakest member.
This dog was no bigger than a jaguar stop this BS big cats have always been bigger than dogs. Bigger bone structure bigger muscles. If this dog was the size of a lion they would have been ambush predators and lack stamina to chase like wolves.
@@Abdi-libaax Epicyons can actually reach weights of 400Ibs or more for the Validus Specimens. Also Epicyons were robust carnivores, as robust as a bear!
Epicyons were likely Ambush predators as a 400+ plus canid is not chasing down any prey but having ambush hunting tactics like Lions.
@@S.F157"Epicyon Haydeni was as robust as a bear" 😄 no it literally wasn't...
What if epicyon was man's original best friend? 🤔
They never met, Epicyon went extinct millions of years before the first hominids appeared.
It went extinct 5 million years ago. Morder humans are 3-200,000 years old.
If we manage to create exponentially large dogs or fighting machines like fighting dogs. Imagine what would happen if humanity used artificial selection on a giant canid.
Imagine a guard dog made from Epicyon. Taking into account that dogs have managed to develop a better bite than wolves in some cases, we would also be creating a guard machine.
Back when men were giants.
Coyotes do indeed hunt in packs. In my home province Alberta they kill many deer on the prairie and the northern bush. Cool vid though thanks
Coyotes certainly do hunt in packs where I live, western NC, between Charlotte and Asheville. Within the last 25 yrs they have driven native foxes, red and grey into the margins and whereas they were silent here, we now hear the exact vocalizations that I lived with on the Idaho/Oregon border.
We use mules and donkeys as guard animals for our horses, sheep, cattle etc.
Just here from Colorado agreeing with both of you. Coyotes definitely hunt in packs.
Danny Devito could still kick its ass 😂
The sequence where you list the animals Latin names and show pictures of the creatures is very helpful. Showing the art and drawings of the creatures helps me to understand and remember them. My wife said the same thing. It makes the different animals in the videos very interesting and easy to remember.
Say ‘fossilised faeces’ twenty times really fast. But seriously- thanks mate. Really interesting and researched and easy to follow
Yea mate lovely video son
Am glad you did this video bc there are not a lot about Epicyon!!
I love it when you go through all the other animals they lived with on these vids.
Very insightful and informative, Great video 👍👍
Thanks for great selection of artwork & bones 🐕👍

Guh…guh….Good Dog!🤣🤣

Also humans enjoyed pack life. We still do.
I was in a wolf pack as a cub scout.
Great channel
9:04 why apologise bro? U casually drop movie quality vids every week. Hope ur channel grows more since u really deserve it
Yo Dawg, that video is off the chains !
Interesting vid....This was something I always wondered about when I was a kid. I wondered why the biggest dog (the wolf) was comparable in size to leopards, and how come there were no dog counterparts (size wise) to jaguars, lions and tigers. Of course, none of the books I had back then mentioned Epicyon, or, if they did, no mention of its size was made. And back then, lots of things weren't common knowledge, even to those like me who had such interests. No one knew what a velociraptor was, much less Epicyon!
Isn’t a Saint Bernard bigger than a wolf? Some of them look comparable to lions in size 😮 though I think that’s not natural it probably required selective breeding
I feel like Europe needs to watch out on their escapee big cats from zoos and old travelling circuses, apparently we have some spotted in UK, France, Germany, Switzerland and more.
❤ this content, AND the Danny DeVito cameo! thnx
great video
3:15 damn.. Danny Devito as Reference....and I just realized that im significantly taller than him💀
so theyre real wargs
@3:09 I can't believe you used Danny DeVito as measuring stick to these dogs. 😅🤣😂
0:20 Thanks for the map of big cat habitat ranges! I had no idea that leopards were so widespread, especially in China. And I had no idea that the range of lions is so horribly limited. Back in Roman times, they were all the way up into north Africa and the Mideast. Finally, I had no idea that pumas were so widespread, all the way down into Brazil, Chile, and Argentina.
The map might be inaccurate when it comes to leopards at the very least. Leopard distribution in India is certainly more than what the map shows and while China historically might have had that distribution shown on the map, today they have only around 400 leopards.
The second map is definetly inacurate at least. The range of Grey Wolves is quite a bit bigger in Europe than what the map shows.
@@prithvipramod8653yes. Leopards are found all over India, and there are around 12 to 14,000 leopards in India
He a good boi
A very impressive list of names and extinct animals!
Video idea: list the most successfully reigning animals based on millions of years within the fossil record. Perhaps separate videos for predators and prey. I think this would further broaden our perspectives on how truly successful these animals are. The Epicyon and Barinasuchus for example reigned for quite a bit, while many popular and perhaps overrated theropods reigned for much shorter. Allosaurus did quite well for a theropod.
Many more discussions can be made by analyzing these statistics, though I understand it is difficult to get reliable results based on the fossil record. What kind of predators reigned longest? Are there any common traits between them (pack hunting, scavenging, size, etc.)? Do certain families have longer success rates (Canidae vs Felidae etc.)? List of potential video topics can go on and on from there!
I need a video on a bear dog! Lol tbis was a good video great job!
Great channel. Im looking forward to my subscription alerts. Im fascinated by the deep deep past of life
I have a suggestion for a video , can you do one on the giant hyracoid titanohyrax ultimus ? It was one of the weirdest large herbivores of its formation and I think its pretty interesting and underrepresented in media ( it could reach 1.300 kilos ! Thats the weight of a male giraffe ! )
I’ve been binge watching ExtinctZoo videos while fasting😊
8:27 ....SEE MAN 🤣🤣🤣🤣🤣🤣
The most successful predator is actually a very, very *small* cat. XD
Most successful is the wild dog
They have highest percentage kill
@@TheUneducatedTeacher alright, so looking into it, the black-footed cat is is rated for the highest hunting success of solitary predators, while the painted dog's impressive success rate is only as a pack.
@eadgyth5009 from what i know the most successfull hunter in the wild IS by far the dragonfly with a success rate in solo hunting of 97%.
Ooh! A new fantasy pet for me!!
It's not for nothing that we got along with canids so well. They may never have been terrifying monsters on their own, but they quickly understood that team work open more doors than it close. Their story is the same as our, you live alone as a prey, or become a predator with your pack
3:57 what app did he use to see these measurements?
Even though their big, they were the biggest good boys ever...
THANKS VERY MUCH FOR THE EXCELLENT VIDEO......
Old F-4 Shoe🇺🇸
years ago I had a dog that was a cross pyranine central asian mastiff....I didn't breed him but I had him desexed.Biggest dog I ever saw. Biggest dog the vets every saw as well....112kg and his head was 14 inches wide and he was about 7 foot long.Didn't care about electric fences could break a dog chain without thinking about it..Lucky he was a lovely dog. The fact that Epicyon was considerably bigger than him and ferocious made that beast a monster....
How does compare to a huge ass wolf hound or Newfie? Like the biggest ones we've bred?
Imagine if many Epicyon Haydeni were around today? Some hunters & farmers with their hunting & livestock guardian dogs would be a little unnerved.
Can you imagine having those puppies crawl all over you?
Where are the big dogs?
Me laying in bed watching this video“ I’m right here”
Really beautiful and interesting
Witnessing the craziest animal fights in the wild reminds us of the harsh realities of survival.
Man, I saw a show years ago that broke down how wolves came to rival big cats as sucessful predators. It was excellent, and I've never been able to find it. It described how pack hunting worked and how it allowed them to compete despite size and tooth "disadvantage" (when compared to cats).
WHO let the dogs out? Who?!? Who?!? Who?!?
What is the insect with wings and scorpion tail? (9:38)
Uh oh. Wikipedia research strikes again! Cheetahs and mountain lions fall into the small cat category.
Yes he said that they were comonly called ''big-cats'' even tho they aren't part of the panthera genus wich is needed to be part of the Big cats.
What he meant was that genetically they are ''small-cats'' but they are closer to big cats from their size, behaviors and place in the food chain.
I am quite surprised canids that canids don't get bigger than this is because they are pack hunters and have to share meals.
3:14 - This needs more attention. You’re welcome.
If only the American Lion and Epicyon Haydeni were around at the same time period? Would they compete against each other? If so, their battles would be legendary.
They competed against a similar size machairodont named “Amphimachairodus” which was a competitor of Epicyon. They were similar enough to an American Lion to basically be a counterpart of them but from the Miocene. So a battle between the two would be not so one sided as Epicyon were robust and built like bears. Even Tigers have hard time killing Sloth Bears/Sun Bears. Imagine a 400+ 16,000 Newton Bone Crushing Dog as you nemesis? Not something I would want to come face to face with. Don’t believe me? Look up how wide their skull is.
@@S.F157bigger in size are the only way for any dog species to defeat any cat/big cat species. if the dog were smaller or at the same size as the cat/big cat, the dog wouldn’t stand a chance at all. pound for pound any cat/big cat would easily defeat a dog. cat/big cat are built different. their body were miles better than a dog. they have better muscle composition, they are more agile, has faster reaction time, run faster, jump longer and higher. they also has the deadliest killing techniques in animal kingdom which is the neck bite. before the epicyon even have the chance to use that bite force, the mountain lion were already bite the epicyon neck😂
@@m.a.i7324 Epicyons were the dominate carnivores of their time in the late Miocene so technically we can say they were pretty strong to be the dominate carnivores.
American lion only has a bite force newtons of 4,450 while Epicyon has 4x the newtons at 16,000. So even if the American Lion weighs more, is it worth the trouble getting a bite by a 16,000 newton dog? Short-Faced bears were the dominate carnivores of late Pleistocene NA, so the American Lion was a Carnivore but weren’t the most dominant of its environment.
Sure Lion is more robust than Hyena Dog but Epicyon were as robust as Grizzly Bears which is what American Lion Robustility is compared to.
@@S.F157 You act like epicyon were the only carnivore that dominate in miocine duh. In fact there’s are multiple carnivore that dominate in miocine and one of them are a saber tooth cat called nimravids. Nimravids are only the same size of modern jaguar and mountain lions which is smaller than epicyon. Both nimravids and epicyon lived at the same place which is in north america. If you look at our modern day animal kingdom, the only place that a dog can dominate the area if there are no presence of a big cat. Nimravids are smaller, both of them lived in the same place but nimravids also can dominate literally shows how strong a cat is. The only reason epicyon are one of the dominant carnivores in miocine were because in this period there are not so many big cat species and the big cat species were also smaller.
Back to our epicyon vs American lion topic, max weight that an epicyon can reach were only 170 kg and max weight of American lion were 250 kg. As i said in my earlier comment, the only way that a dog can defeat any cat are if the dog were bigger which in this case American lion are way bigger. Cats are way faster than a dog dude that dog bite force is no use when the neck of the epicyon already get bitten by american lion.
@@m.a.i7324 false false and more false. Nimravids were around when Epicyon was the dominate carnivore but not all Nimravids were small.
Amphimachairodus (Machairodont) & Barbourofelis (Nimravidae) were large feliforms and both were larger than Epicyons at their maxes, but Epicyon still coexisted with them. The reason is because they (Epicyons) were dominant carnivores. Epicyons reached maxes of 181.44kg (400Ib) at their maxes if we include the Validus specimens (Epicyons that grew bigger over time). They were evolving to get larger before their extinction, showing their dominance.
With a strong bite force I don’t think most carnivores would bother with this fella. When it comes to most canids compared to large Felids, felids tend to be more robust. But Epicyon was a whole different kind of canid, big, strong bite force, robust, it was ambush predator (indicating it was probably too heavy to run after prey; the Haydeni species at least).
It's worth making a distinction between canidae and caninae, the next category up.
you pronounced scarcity right if you had an English or Australian accent. love the video, learned some new things. Thank you for your work if you read this.. if not... still thank you very much
Who's a epic boy, yes you are
We have examples of modern dogs with giganisim that are of similar size, Zeus the great Dane over 7 ft tall and zorba the mastiff 343 lbs

Caveman's best friend
@3:10 Danny Devito would probably be very happy to be used as the yardstick for the average height cave man in the prehistoric era 😂
I've been fascinated by dinosaurs and prehistoric mammals from I was a child. Scientist can only speculate what these creatures ate, how they hunted and which modern day animal they are related to with the help of fossils and comparing those fossils to modern day animals. Mystery these creatures provide makes us keep begging for more and we will never get bored.
Please do more videos on uncommon extinct mammals
I wonder if they could have been domesticated? I’d bet yes.
any idea of the artist at 9:18 ?
Canids have whiskers too
Lived in Yosemite National Park for 3 years. I’ve seen two huge pumas or mountain lions there. But saw a HUGE black bear. Maybe 2k pounds. Cats were near 200 lbs easy.

Always interesting when I see typos on graphics. You've got one job. Maybe the person wasn't fully "Domesitcated."
A male bearing his teeth must have been the most terrifying canid ever. You'd be dead in seconds.
Pretty impressive speed to take down antelopes. So it begs the Q:? Were these ambush predators or worked in packs?
Can you make a video on the Acrocanthosaurus.
Beautiful dog, beautiful cats I mean, I love animals all animals that exist. I’m an animal lover.❤❤❤❤❤❤ very beautiful both species, cats and dogs

Excellent job and presentation. I would just correct your Latin pronunciation (no real problem, it's a dead language and the "Latin police, known as centurions if from lower Italia and Cylons if part of the Latin space force, are gone. Canidae- the dae pronounced as day. Keep up the great work and I love that you did not ruin the presentation with a robot voice!
4:09 grizzly bears can reach 150cm in height to the shoulders
What about the Permian Gorgonopsids ??? They were pretty big too !!!
You don't have to go back in time to look at the biggest and scariest dog ever. Just look at Tibetan Mastiff today. That dog can kill a wolf.
A chihuahua also could easily kill a wolf.
If the wolf choked on it.
I wanna see more of those Bear Dogs 😂
“ because of its size, most predators probably avoided them” because the Jack Russell Terrier was not yet around
