The rise and fall of ancient walruses, and how modern ones got their tusks, is a story that spans almost 20 million years. And while there are parts of the story that we’re still trying to figure out, it looks like tusks didn’t have anything to do with how or what these animals ate.

If walruses were extinct we’d call them saber tooth seals
I'll call em that anyway
Saber-like teeth is common in all synapsids, Gorgonopsids had them, eons ago.
I never thought about that before!
u would do what?
I will never want them to go extinct
The way these ancient animals are drawn and animated, its just amazing. It's always the best quality, thats why i love this channel.
You do know that they didn't make the Art, right?
@Jennifer Luecero English Huh
It's very clearly of better quality than all the others I've quickly checked.
2:38 "Enormous walrus"?!?!? They are already terrifyingly massive... *shudders*
enormous as in actually multiton
Are you calling me fat?
Their mass is big and it keeps getting bigger
@@thewalrus148 please no puntarino Wally
@@anarchyantz1564 I thought that it was Elephant Seals that did that.
"Tusks don't make a Walrus". I love how this channel also gives you educational wisdom.
Seriously, TIL this
It translates to:
"What others see doesn't make who you are, it's whats' inside you (refering to the bone plate)"
"Sticking feathers up your butt does not make you a chicken!!"
@@tehbonehead nor a dinosaur
Tusk you very much
Your walcome...
Gotta love the evolutionary arms race. Crustaceans: Grow super hard shells. Vertebrates: I'll raise you jaws and teeth.
Crustaceans: noooo you can’t just break our shells with your teeth
Vertebrates: haha teeth go CRONCH
Crustaceans: grow shells made of literal iron
Vertebrates: I got nothing
@@professionalpainthuffer Vertebrates : vacuuming intensifies
To quote Hank Green: whenever paleontologists don't know why something exists, it's always sex.
Sure, astronomers do the same thing only their base hypothesis is a collision
Well THAT'S because: "Life...finds a way..."
I think when archaeologists don't know what an artefact was for they say its for ritual use :p
@@kanrup5199 that one always cracks me up 😆
I mean... at the end of the day, reproduction is what it's all about 😻
We cannot let Callie get away with “Tusk you very much”
There are limits! :P
I like the puns.
Callie can do no wrong!
We can, and, let's be honest here for a moment, we will.
Should he/she be taken to tusk?
The main thing I learned that was about 15 million years ago I would have had beachfront property here in California...
tbh, I'm surprised your don't have way more subs
And where I live in California, I would be underwater
... give it a little more time... :/
Everything Science subbed
And you might have it again. Think about where you are going to put that boat ramp.
Can we just appreciate all of the hard work that went into this final product of a video? So many scientists, journalists, video editors, artist, etc... that worked hard to get this information out into the public! I understand that it wasn’t directly working towards this one video but it’s certainly a great outcome! I mean this about every scishow video, thanks for the hard work.
I look forward to Kallie’s puns and Blake’s utter exasperation over them. These two fossil dorks give me so much life! I love this channel!! 🥰🥰
Please never stop making these videos they're just awesome
"Tusk you very much" is all good, but "tusk you very much, that doesnt make any sense, but so-and-so's making me say it" made me spit my breakfast. Hilarious
"Which I want to remind you are super duper extinct."
Sounds like someone recently watched The Meg :p
They made a vid on why the Meg definetly went extinct. Must have had a lot of comments there...
Peek- At -Ch'you Ya, all we have are some dumb elephants😒
@@chenthelegend3110 We may not have those for too much longer.
"How the Walrus Got Its Tusks"
The sabre-tooth tigers were no longer using them so the walruses were like "hold my beer".
You've chosen.. Correction
Nice one 😁
Sabercats were like, "hold my fangs" and walrus went, "yoink"!
Goo goo ga joob...
Hold my beer? More like "open my beer"!
I would be very pleased if they did a video of how seals went from land to sea!
@@ESL-O.G. that's exactly what i said?
@@leggu2510 I read it backwards. My bad.
Moth Light Media did a great video on that very topic called "The Evolution of Seals."
@@dinohall2595 i actually saw it! I wish more people knew about them though
"Walrus-ness" is kinda awkward.
Maybe "Walrosity?"
Oh, I love that. I'm going to try to work that into a conversation.
You can measure it with a Walrometer.
Walrusitude? Walrusian?
It was Walpole...
Wal are you all talking about?
The running gag of terrible puns at the end is the best 😂
This is honestly my favorite channel, I get so excited when I see a new video is out😇
These kinds of videos are why i love this channel so much. Illustrative, honest and informative content.
This PBS Eons series on UA-cam is some of the finest educational content on the web!
Love that Rudyard Kipling style title
Just so story
They need to start one of their videos with "Now, Best Beloved...."
I love how the voices in these type of videos make u want to learn more
Yes this is exactly what I need right now
The german name "Walross" consists of the names for "whale" and "horse" - so we present you the mighty whalehorse!
I like this informational comment so I shall share, In chinese "penguin" consist of two parts translating to "Business goose"
@@jadedmist 企also means standing in common usage. A penguin is literally called "standing goose".
@plentyness Old Norse hrosshvalr, ‘horse whale’, is believed to be the origin for the various Germanic language names for walruses that we use today. English being English, the language drifted really far away from anything sounding like "horse-whale" (at least to me, a native English speaker who barely knows a few words in any other languages), while it sounds like German and Norwegian both remained closer to the original word components.
Mammut the name for Mastodon means mammoth in German
Damn Jamie Hyneman is looking great after mythbusters
Omg whyyyyyyy 🤣
😂😂😂

I accidentally clicked on this video while trying to search for cool ocean animals. I guess safari knew what was the coolest animal already.
Y u no google? Lol jk
I'm actually more surprised to hear Safari :P (not that I have an opinion on it, just no one seems to say it)
Well said
Joe Potts oh, uh no reason actually. I also have google, but for some reason I just use safari more. I know googles better I guess, I just use safari more.
Joe Potts ya it’s a bit weird I guess
4:43 that walrus was a snack for the terrifying giant dolphin behind it
Thank you for the video PBS studio's and crew!💞
Hi Eons. I’ve been thinking today how amazing it would be if you released jigsaw puzzles as merch: illustrated tree of life, grid of the best paleo art... I’m sure it would sell like hot cakes. Thank you for all the awesome!
i am a simple man, i like simple things, but when i see an Eons video that will talk about complex things, I CLICC.
I'd love to see an episode on elephants 🐘
William Melgoza me to
Me 4
Go check Moth Light Media's channel, he has 2 videos on elephants evolution :)
I thought they did make a episode on elephants.
They did the Pygmy elephant in an episode
I have been watching for a while. Thank you for all the content. Hands down my favorite UA-cam channel!
“Is man, indeed, a walrus at heart?”
Dude getting ripped lmao
I learned so much in this episode! Also I got the poster from your merch shop and it’s my favorite poster ever :)
thank you for making these videos. they are among the best on youtube.
Yall sleeping on the artwork because like damn its amazing, so life like
im so grateful for this channel. Like for real.
Looks amazing! Can you do one about the giraffe's neck or how elephants came to be? I also want more videos about the dinosaurs because we have yet to hear about the origin of flight.
Has Blake been working out? He looks Jacked in this video
I binged a bunch of these a couple weeks ago, and he has most definitely bulked up over the last year.
@@alison4316 he now looks like Arnold Schwarzenegger
I so love this channel! So informative so relaxing and refreshing!
Interesting tale! Thanks for uploading!
The answer is quite simple. The walrus class earned enough xp unlocked "Tusks".
Ah, a tier zoo fan
A man of culture*
Oh please, CreativeNick. They got them on Amazon like everybody else.
Same here. And they can body seals and narwhals with those tusks using the move stab.
Btw I’m an orca main
I’m one too lol anyway r u a cat main?
Would love to see a vid on hippos, lads keep up the great work
I've always wondered whether there would be a seal, probably an Elephant seal that was the size of a Humpback whale. If there is, we'd love a video on it, PBS Eons!
I learn new things all the time, I love it! Maybe we'll see an episode on the narwhal's tusk.
From now on, I will only refer to Blake as Palaeo Daddy. And I'm a straight man.
We had just went over dentition in Anthro last semester (but not yet social ecology) and the walrus' in particular perplexed me. This video filled in some of the questions I had. Well done
Great video as always, could you guys do the evelution of beavers and how they devolped the behavior of building dams?
Day 1 of asking eons to cover the new discoveries about Spinosaurus
So the weird, watery tale of the Spinosaurus should be remade by them?
Wait, what is it??/
Excellent video. Greetings from Chile! :) 😀👍👋🙋🇨🇱
On my covid wish list is a new Eons video daily PLEASE!
Come for the science, Stay for the amazing puns!
I love this show so much, thank you!
Even the Walrus' skull looks like Wilford Brimley. Amazing!
Hey thanks for everything you do all of you guys . Can you please please make a video to cover elasmotherium ?
At the end of 2020, we should all yell JUMANJI to get out of 2020
Would that end the irrelevant comments as well?
SirpentPlayz 2020 won’t end 2021 will just be a remix of 2020
@@Ricardowieringa It will probably be worse ... but it's still worth a shot.
Already did
@@FortoFight i would hope so
0:37 , cover of Male Walrus Fitness magazine.
Also PBS; there is no reason to be scared of the Megalodon MiBs , just tell the truth
You may not like it, but this is what peak performance looks like
Sapphire-Peridot King Facts
You know what. I'm gonna say it. Old earth was scary asf but it seems like it was such a vibe. There is such a broad variety of species and animals, and those who are around today have changed so much. It's just so interesting!
Last time I was this early, walruses didn’t have tusks :P
🙈
🙉
🙊
Well I was intrigued to learn about this
This video is really impressive because this guy remembers all this stuff
I'm from the center valley and it's like living in a bowl. Were surrounded by mountains every direction. I never knew I megalodons roamed the same land I walk. Crazy
great content guys. dont forgot the pinniped and tyrannosaurid evolutionary histroy
I love your videos ❤️
They r very interesting and informative
I think you said something about walrusness, but I was completely distracted by your ripped forearms.
Dude walruses are more important than a random generic guy
Gotta love Callie's puns!
earliest i've ever been and kalli's puns are hilarious

Aww yea, bigass prehistoric walrus! PBS Eons always there with the bigass prehistoric animal videos
6:41 caught me off guard
Came from Palaeocast, you just gained a subscriber 👊🏽
Welcome aboard!
"How the Walrus Got Its Tusks."
Was it the eggman and the eggmen? (Goo goo g'joob!)
Not funny didnt laugh
Very funny, did smile with sound
I love how Blake always blames Callie for the bad puns!
Please do a video on bioluminescence and fireflies!
Can you do an episode on the evolution of the eye some time? I'd love to learn more about that!
Ur voice is awesome. Like a coffee
This is the only UA-cam channel that I pre like the videos
Thank you for educating us during times where we have nothing to do
I love this channel because of the amazing knowledge. 💗💗💗 Keep making!!!!
Has Blake always been so jacked?
this is the reason im subscribed
Interesting story about the evolution of the eggman, I am the eggman I AM THE WALRUS KOOKOOKACHOO
been a while since I was in time to watch a PBS Eons video
I love Kallie’s puns 😂
Exceptionally educational!
Son: daddy, why do walruses have giant teeth?
Dad: You’ll learn when your older son...
"Megladon, which may I remind you, are SUPER DUPER extinct."
You know it's serious when he has to add the 'super duper' to it.
7:12 I didn't know humans were present 2,6 million years ago
We are great time travelers
Not Homo sapiens, not even Neanderthals, homo habilis and erectus, but still of the Homo genus, therefore human
@@4scended498
That's why we don't tend to call our cousin species as human, because we like to call ourselves that. So hominids is the common grouping.
Anatomically modern humans appearec 200k yrs ago but our ancestors were already there
He wasn’t saying that the presence of humans became an active factor AT 2.6 million years ago. And he wasn’t saying that the number of walrus species crashed all at once, AT that time.
He said that the drop-off in species diversity occurred AFTER the end of the Pliocene, which was 2.6 million years ago, and can be attributed, ultimately, to the convergence of multiple factors since that point. Not all of them emerged at the same time, and the significance of each one has waxed and waned in that 2.6 million-year period. Obviously, the impact of humans on walruses became significant later on in that period than, for example, earlier episodes of climate and sea-level change.
He could have pedantically spelled all that out, but he’s trying to convey a lot of information concisely, and no doubt felt this audience is probably intelligent enough to connect the dots, and not have every detail explained to them like they’re six years old.
Walruses are phenomenal at playing Twister
Wow, he's getting more buff by each episode. Yummy?
that bulge too!
indeed an eye candy with arms like these 👁🍬🍭 a true beefcake🍖🥩🍰🎂
Thank you for your great videos!
Evolution: makes an animal have strange and apparently useless structures
Scientist: why does this happen?
Evolution: S E X
The film “TUSK” in 2014 gives one a great education in Walruses!
You're right, that made no sense at all. Kallie should have made you say, "Thank you vary tusk!"
i like walri they are funny and very big. but I saw a thing on TV a few years ago about a tame one who lives in a aquarium somewhere and he helps scientists do walrus research and he is rly friendly 💕
Wait, Walruses have the stand tusk, does That mean Johnny Joestar is a walrus?
Fascinating. Thank you.👍
Man, this has nothing to do with anything, but i always found that you reminded me of someone and i've just figured it out! You look just like Howard from Better Call Saul hahahaha anyways, loved the video :) Great work
Last year I watched the netflix series titles "Our Planet" the one thing that really stuck out for me is the damage we have done to the walrus population. We drive them into small crowded islands where they scale impossibly steep cliffs but due to their body shape they can't get down safely, and almost all that climb up loose grip while climbing down and tumble hundreds of metres onto the jagged dagger like rocks below. The number of dead bodies is absolutely horrific. I urge anyone here to go watch that series.
