Thats why dogs bury their bones. In memory of their dead ancestors who had fallen to the cat hordes during the great war.
Lol
NUUUUU rip big doggos....
They can't crack them, so they're sending them back to the dogs that could.
they're canidae, therefore they're dog
To soon.
Actually, they're closer related to wolfs, foxes, and other modern day doggos than to bears, otters, seals, etc. Where's your logic here? They were even in the same family, and might have had a similar bone structure.
From crushing bones to barking at doors. How the mighty have fallen.
It's the same with humans. We used to hunt prey by chasing them for miles in small groups.
Now we just sit and watch TV stuffing twinkies and beer into our pieholes.
@@actsrv9 but if the need comes we can create havoc with all the nukes and guns we have...much more than our ancestors
Cats got it the worst they were literally seen as gods in ancient Egypt. Now they stand by there bowl side giving you the sad puppy dog eyes waiting for there next meal. Talk about how the mighty has fallen lmao. They went from gods to a feline Oliver twist.
That could be said for nearly all animals

Long ago, the three nations lived together in harmony. Then everything changed when the *Cat* Nation attacked.
Cats rule
Cats barely did anything to their extinction. It was a mix of catastrophies like change of climate, competition with other bone chrushers, Canines (yes, the dogs we have today is one of the reasons they are dead) and more! Canines evolved to use stamina than brute power or bulk. If you think about it, their extinction is like Megalodon's, change of climate, new species, and competition. Stop thinking cats are the reason they are extinct because cats barely did anything.
This was inspired by Some body.
@@wolfblade9530 they also compete with cats, so they didn't really did barely anything
@@taiyo9421 Epicyon competed with a-lot of animals like Canines, Bond Crushers, and cats.
Dogs millions of years ago: BONE CRUSHERS
Dogs now: scared of firecrackers
Follower of Saints
Dogs now are also bffs with the T-800, so, make what you will of that
Like the video mentioned, dogs have great hearing. Their ears are sensitive. Anything loud is painful to their ears. Just like when someone screams in your ear, it's loud, and it hurts. :/
Not my dog.
To be fair, a bone-crushing dog would also probably be afraid of firecrackers.
You would know the real feelin of scared if you firecracked my dogs
And eventually developed the most amazing adaptation ever: Convince humans to go to the supermarket for them. That's the real top of the foodchain.
Dogs have become the New Master Race or maybe Cats?
@@riddickmarkus69
Cats don't even need to be taken on walks and rarely need your attention. They are the master race.
They could be better it wouldn't have gone any better
@@brooklyna007 Cats aren't as social nor as intelligent as dogs, as well as being less of companions and more of serial killers, which makes dogs the better choice, being tame but without really losing their primal instincts.
They may not have the most horsepower in their heads, but dogs are the smartest animals in the world for one reason: they’ve teamed up with the apex animal. They are (for the most part) not considered food by us, and live in our homes as a family member. Chimps and dolphins won’t be going to the stars with us, but dogs will.

While I was watching this my dog farted so loud it scared her awake and I’m here like... I can’t believe you had such ferocious ancestors you lil wuss.
Dog: right back at ya
Ah yes, the canids made it to Africa and early humans bonded with them like "oh, you play the long-game exhaustion hunting technique? Us too! We should go hunting together!"
no coincidence that the other human species without dogs all went extinct. We have a lot to thank the mutts for
Destiny, no other word for it.
Joshua Bartlett there was supposedly an ice age at the time, so the equator (which happens to pass through Africa) wasn’t nearly as hot as it is now, so even Northern Africa could have been temperate.
If memory serves the oldest extant dog breeds genetically can be traced back to Siberia note however that dogs were not domesticated just once but several times same with other animals such as cats and camels of the top of my head. They were also domesticated in Europe but those dogs left no living descendants eventually being replaced by their Asian kin.
@@joshuabartlett5575 Aah, you're right! 😉 😉 👍 👍
My cat watched this with me. He's still rolling on the floor, purring out loud.
Evidence
"what are you looking at, hooman? I'm innocent!"
Think about it. First cats outmatch dogs in many environments as top predators, then they manage to enslave humanity while doing nothing for humans except causing allergies and scratching furniture. Those purring little bastards own us!
@@robwalsh9843 and I wouldn't have it any other way! 😄🐈🐱
@@robwalsh9843 Mothlight studios makes a good point on that though, in the wild the big cats are going endangered and no cat has ever topped a dog in running stamina which is why both are still evenly matched in their respective lands
So, dogs adapted to a strategy of running prey down long distances, did they?
Sounds familiar...
Yes. Perfect match because it started with a rivalry. Packs of dogs and packs of humans hunting same species of prey with similar strategy. At some point they realized it would benefit both if they hunted together instead. ;)

It doesn't. Cats and Caninae got along well - cats just eliminated the bone-crushers, who very likely also meant competition and peril for the Caninae.

Rain thunder Same group, Pronghorns are the only surviving species.
What kind of animal is that thing with epicyon?
You asked first, so I'll answer here. It's Synthetoceras, an artiodactyl that lived in North America during the Miocene. Think we should do an episode about it and the other protoceratids? (BdeP)
@@eons Yess! The large and bizarre eocene mammals are fascinating
It's either Prosynthetoceras www.deviantart.com/ardynictis/art/Prosynthetoceras-francis-761034849 , Synthetoceras, or one of the early ancestors of Jar-Jar Binks.

Thanks a ton for sharing your findings trough your dedication,great work!
When they say that the ancestral dogs had fully-retractable claws like cats, I thought there may be more to the story. Something like them branching off from a common ancestor. Kind of like siblings who didn't like each other and divided the world between them until cats decided to take over the dog territories...
They did have a common ancestor, the miacids mentioned at 1:16.

I imagine if bone crushing dogs were still around, house cats would be like a snack for them. In the same type of way that you feed a large snake a rabbit or a chicken, ya know? Sure it’s technically a pet type creature, but to your pet it’s also edible.
I am especially appreciative of the writers of this series willingness to say that something is an unknown or a theory. One of the greatest mistakes I encounter is when experts present something that is thought to have occurred as a hard fact. This is a vital difference between evolutionary theory and theology. Scientific theory is a fact that incorporates guesses. Theologists posit that scientific theory is ALL theory, i.e. NOT fact, and that theology presents as fact. This, in my view, is the difference between education and dogma.

Why do so many of the pictures make them look like various domestic breeds of dogs?
Joshua Hillerup yeah one looks a lot like a pit bull or mastiff
Because artists are often not scientists.
Artistic liberty. Not scientific art.
1) It's paleo art. If your a paleo artist, it's kinda your job to know what they animal looks like. And they aren't just your usual painter.
2) Scientist is a very broad term. It's everything from studying insects, to studying space.
Another thing to consider is that with their hunting style and powerful jaws, they probably did have shorter, broader snouts and heads, making them more akin visually to mastiff breeds than wolves.
I love paleontology because we can see an entire evolutionary arms race spread out over millions of years. It’s brilliant!
The Dingo arrived in Australia 40,000 years ago, not 4,000 as stated in this video. There are several subspecies/breeds of Dingo ranging over a number of countries. Apart from the date error, this was a brilliant presentation.

I laughed way to hard and long at this
Love this channel!!😀 it's so informative and entertaining and interesting.
Possible future topics:
How photosynthesis evolved.
Gorgonopdids and other animals of the time.
Ophabina, anomalocaris, and other such early blizzard creatures
Kaprosuchus and other crocodilomorphs like armadillosuchus
(You guys are way better at coming up with topics though so just keep doing what your doing, because it's awesome 😀👍)
There NEEDS to be an episode on the crocodilomorphs!
+The Creature Wow. I'm surprised I actually can't find anything on how cyanobacteria evolved, or what their immediate ancestor was. PBS Eons does need to do a video on the evolution of photosynthesis, as you have said.
Wasnt there already a video on the gorgonopsids?
Oh! Photosynthesis Is a GREAT idea!
They already did one on evolution of photosynthesis
It's right here

I blame everything on the cats!😂😂😂😂😂😂
"The rise and fall of the bone-crushing dogs"
Hyenas: meow
hyenas are actually more close relatived to cats
Sorry to nit-pick, but that painting of epicyon with its floppy ears is terrible. Floppy ears are useless for an animal trying to survive in the wild. Floppy ears are one of the traits linked with domestication; see Dmitry Belyayev and his famous domestic fox study.
And domestication seems to have made them stupendously successful, bending us to their will with their floppy ears.
It makes it look like a giant pit bull.

That's the thing about people. They tend to be unable to imagine certain things so they just resort to what is already familiar. In this case, since the artist didn't have all the information, inspiration was taken from modern dogs.
True but if you are going to present a rigorous time line for the emergence of species you should like wise be rigorous in any representation of those species you present I would say.
It's pretty well known that floppy ears are a hallmark of domesticated animals ...not just dogs in fact, it is further not a trait that would be selective in an environment where humans don't exist and the efficiency of hearing is reduced due to ear flop (yes...it is). So it doesn't make sense in any direction as a trait to be shown in renditions of a canine species that lived millions of years before homonins separated from the LCA with chimps.
I don't care what you say dogs and cats ore at the top of the food chain they get humans to do their bidding without question
FLAMING RAINBØWS not all
Uchenna RUclips factual
They so cute,, I don't mind it.
@@sunnishae5047 me neither i love cats
I think there is a difference between a social chain to a food chain.
Now make a video of those ancient cats pls. How they evolved and spread throughout the world, how many of their species went extinct and how many other animal species they managed to "eliminate". :P
Excellent video! I actually learned something.
I always heartily enjoy watching Eons, but I’ll sing praises to my cat who caught a Nola rat. Every pup I’ve had were only good at hunting down belly rubs.
Cats are the better hunters than dogs. It’s no competition.
They protecc
They attacc
But most importantly,
They eat bones for a snacc
Edit: thanks for all the likes!
That rhymes.
Foalan sounds so familiar
Dogs still do that...
ICONIC
YES
Where did you get the maps from. I like them and they seem to explain more about the landscape than I've seen before.
The title of this video sounds like a prog metal album.
