The biggest turtle ever described wasn’t an ancestor of today’s leatherback turtles or any other living sea turtles. But it looks like there are some things about being a giant, skin-shelled sea turtle that just work, no matter where, or when, you lived.

Big boi there looked like he could stand to have a couple elephants stand on his back..
Ah, I see what you did there!
GNU Sir Pterry.
Great A'Tuin...
Disc world is really distinctive huh
I reckon four elephants...
Man, Crush sure has been living his best life as a sea turtle.
And that's rightceus
LOL
*Righteous
yeah, but he's a hard shelled sea turtle...
Sea turtles are true survivors and they have been on this planet for millions of years. Not bad for such gentle, slow-moving creatures.
Yessssss turtles are number one
You wouldn’t need to move that fast if you lived that long 😝
I can’t wait for the discovery of the saber tooth turtle, carnivorous super predator.
I wonder why the panda still exist...
@@gamedev020 idk either they dont seem to wanna stay alive 😔
"Instead it just had a framework of ribs covered by rubbery flexible skin." Just like me!
You got that layer of insulating fat also🤣
@@FAHCORE oof, now that's some damage.
Archelon: If you throw one more straw, I'm throwing you off your boat.
Yeet da boat
Lol, too bad they were probably docile like most large ocean animals
Archelon could get in my pokeball
@Galaer I think he means modern big sea animals 🤷♂️
Archelon be flipin boats ahahaha
My mood right now: eons and something to eat
Yaaas. 100%
Meat
Same...
My mood:
My bed is so comfortable. But must leave to get food.
same here :D
Welcome back giant sea turtles! 👋🏽🐢
No
No thank you
No
I for one, welcome our new giant sea turtle overlords.
They're back!
THEY'RE BACK YES
We must protec them
A video on How parrots developped "speaking" please. That would be interesting
That would be so amazing
Omg yes
they repeat not speak
@@lolikususs There's some debate around that, esp. when it comes to African Greys.
@@Riceball01 So we have other species who learned english or what??I speak 3 languages and English is not my best, but i want to see how porrot speaks with thinking..
technically, if you count swimming speeds, turtles are both the fastest and slowest reptiles on earth today
Arent crocodiles and alligators fast in. Water too
@@SheLikesLoons sea turtles can get up to about 30 miles per hour, and more to the point their long-distance travel rate (what they are actually built for) is right up there with other long distance migratory sea animals, IE they lazily amble on down the road at what would be a dead run to you, and you're pretty dam fast by land animal standards (again, over long distances)
heck, even the little river turtles get around pretty well and they have much less reason to since they aren't trying to run from anything or chase anything down or travel halfway across the planet.
I get that they were trying to be funny but this is at least ostensibly an educational channel and they never included information to the contrary in the video, just kept talking about shells and playing on stereotypes.
@@SheLikesLoons Yes but nowhere near as fast as turtles.
*Answer the question Annie.*
@@SheLikesLoons @Doom Slayer Alligator water speed is 20mph, not as fast as the leatherback sea turtle, which reaches 22mph
It's surprising that no sea turtles ever developed live birth. It would seem to have a lot of advantages over crawling up on land.
They still need to breath dude. Turtles have tons of babies at once. Plenty of them would drown if it gave birth in the water. Its not like sea mammals who only have one at once.
@@XWierdThingsHappenX a lot more would survive if they didn't have to fight the gauntlet from the beach to the sea though? So they could produce less at once?
@@nismo4x4n It's not just that sea turtles have predators in the sea and are more vulnerable as babies out at sea learning to live by themselves with no parental guidance. I would see more advantages to just lay a ton of eggs on land and hope that some survive... than take time especially with the disadvantages of having an inflexible towards live birth to raise a few off springs. Also take in mind being pregnant with a shell plate on both sides of the body would be improbable to evolve and also very tolling for the females to swim in the open ocean with predators.
@@slorattlesnake669 (some) Sharks give live birth without changing shape too much though
@@kimberleylannou3424 js, sharks is mostly cartilage, turtles is mostly bone (I think?), so I get the point here
Leatherbacks are an absolute treasure and we're all lucky to still be seeing them around today since their type has only appeared twice before in the last 100 million years.
They all need to be protected at all costs.
All species of animals need to be preserved nowadays atleast the ones that are endangered. Nearly all of life was wiped out within the last 100 million years. It's been said that there is only 1% of all original life on Earth now. So we do need to make sure that we preserve life on this planet, this tiny blue dot, that we call home.
"At all costs"? Really? ALL costs?
@@jacobj3491 Yes.
@@obiwankenobi1608 a large part of that only 1% is alive right now is also just part of the fact the planet is billions of years old and humans have only been recording history for less than 10,000 years. there have been multiple mass extinctions before us and there will be more after, even when it comes to the fossil record, only around 1% of creatures get fossilized and only about 1% of those are in a viable area to be discovered by humans, its a sad fact but a true one that we cant save EVERYTHING. That being said we still do need to have less trash in the oceans so that the current extinctions can at least not be directly our fault lol, i agree there should be at least an attempt at preserving the remnants of any endangered species
@@obiwankenobi1608 remember once they are on the list concern list we should use their DNA to unlock the secrets of a re-creating there prehistoric relatives
Chelonioidae: can I copy your homework?
Protostegids: sure, just don’t make it too obvious
Result: Chelonioidae gets banned for copying Protostegid's homework.
@@5daboz looks like a TierZoo quote.
Shouldn't it be the other way around?
@@marcustulliuscicero5443 yep, archelon came first, should've been that.
Awesome episode, the most concerning for me now is that: The last leather turtle lineage is the most endangered of all marine turtle species. Would be very sad to end this lineage in human/historical time ;-;
So we gotta save em 💪
This is something that was greatly worrying me throughout the video we need to protect our oceans from shortsighted evil of greed
Actually, the most endangered marine turtle species would be Kemp's Ridley Sea Turtle, which is listed as critically endangered while the Leatherback is listed as vulnerable. Regardless, you are right to be concerned about the risk of losing these magnificent animals.
@@taylorblazi1580 That's news for me, maybe I was looking at the endangered species list of my country (Brazil), which has only one nest site for all the country and the fatal accidents with that species are very high, such as bycatch with fishing nets and boats collisions, despite pollution and plastic ingestion.
@@pedrotolipan7496 that might explain it. I was going by the IUCN rankings.
Blake is so awesome! He's an amazing presenter. And he kills every joke. And, yes, that can be read two ways. Don't ever change, Blake!
He kills every joke,😂😂😂a part of me died.😂
you mean balaké
He's killing it in the fashion department too in this video
Your welcome, I am awesome
-a guy named Blake.
Perhaps when talking about contemporary species, you can include conservation status and the threats the species is facing?
Good point. Rally the troops to support if they want to.
I'm stuck in the chaos in central texas right now, and this is exactly the audio visual comfort food I needed 🤍
Search for Beau of the Fifth Column here on YT. He just made a video that might be useful to you.
if you're here in san antonio, you'll also need comfort water... and comfort electricity... and comfort gasoline... don't forget comfort your comfort winter boots too 🤨
@@pizzabella_2356 yea because its cold
@@pizzabella_2356 I'm in Austin and we're at 70 hours without electricity, 30 without water. But I have a gas grill and a costco card so I'm ok. Lots of vulnerable people out there struggling and suffering tho, I expect.
@@Jesse__H stay safe and stay warm man
If you care for sea turtles please consider donating to the sea turtle conservancy (based in panama, costa rica and the usa) they do research on sea turtles (mostly leatherback and green) and they are very important for the continuation of these endangered animals and need the support, especially during corona when no tourists can visit. You could adopt a green sea turtle to support them and this way you are saving the turtles!
I have had a terrible, horrible, no good, very bad day, and Eons and tea are the two things that cheer me up! I didn't know I really needed to learn about the ancient skin-shelled sea turtles today, but apparently I absolutely did.
That is awful to hear. I don't know why but I thought maybe a virtual airhug added to the list could put one more GOOD thing in your day. I hope tomorrow is a little brighter for ya :)
You've described the feeling very well! I've found channels such as this very helpful in the current weird situation; they make even a good day even better. Hope things improve for you.
I love sea turtles, I used to work on a snorkel your boat and saw them every day. Sea turtles generally seem to fit the "slow turtle" stereotype... But that's just because you rarely see them spooked.
We had one week where SOMETHING had happened - maybe pilot whales coming through, maybe a big shark, maybe poachers, who knows - and everything in the water was spooked. Didn't see a turtle for a week, and when I did see a turtle, as soon as it saw me it booked it.
Sea turtles are FAST when they want to be.
Seeing them hovering underwater and then imitating a living torpedo is amazing.
Imagine going swimming and seeing this thing swimming below you
I wanna touch the shell
@@funnyswangoosething5088 can't resist petting instinct 😅
Seeing a Mosasaurus or a Megalodon or a Pliosaurus funkei would make me leave the water at once, but if if I saw an Archelon I would take a ride on its shell.
i would try to ride it xD
@@kwz9930 Who wouldn't? :P
I love how you always mention native people at the end of episodes if the fossils were found on their land! You guys are amazing!
Last time i was this early, T-rex dragged his tail around
And feathers were not even a debate
And tasty.
NOOO THEY COVERED HIS MUSCLES!
Been waiting for this comment
@@tyrekrussell8898 Yup. Let me learn and adore at the same time.
lol
Who knew Johnny from cobra Kai was so intelligent
Turtles/Tortoises are the only thing that can distract me from Blake lmao I actually didn't realize what he was wearing in this one
Thumb up as usual... I have yet to be disappointed by this youtube channel... such quality in the research and such simplicity in the delivery. Thanks for being around and doing this.
It’s among the best of its kind out there. Very well done.
Squad roll up they're talking about turtles 🐢
Turtles number one
I LIKE TURTLES
Turtle 🐢
Sksksksksksksk
Yeah!
Do an episode on when India was an island. I want to find more about the wildlife in the isolated subcontinent after splitting fron Gondwana and before crashing into Asia.
Oooh yes please! I'd also like to know more about this!
I love that the leatherbacks had their little fish fan group always following them around to eat the baddies off of them. It's so cute!
One amazing habit (mentioned in passing but worth emphasizing) of the Pacific population of leatherbacks is that they feed on jellyfish along the California coast and then migrate 6000 miles to breed around Indonesia. Other populations undertake equally amazing migrations.
Creatures are so magical its a blessing
Anybody else find it crazy how they can dive to 1200 meters?!
same i feel like they glossed over that too much lol. I know they love to eat jellyfish and alot of them are pretty deep down there but DAMN
eons daddy is back
From the milk store
Lacking a hard shell may have helped with rapid growth too, which would be useful for passing more quickly through the vulnerable small prey item stage.
"Change is the only constant"
...
...thanks, I'm going to contemplate my life choices (past, present and future) now.
I'm slightly dissapointed that daddy eons has a jacket on
Loooool
The thirst is real.....
Wtf
Yeah... I share this disappointment. 😆
I just want to know where he got the jacket. I want one.
I've seen that fossil turtle in utah!! Amazing how big it is
You have seen nothing. You think that’s big? Wait until you see my electroball-thunderbolt combo
I love that they acknowledge the native contributions that are so often forgotten
My thoughts are with the sea turtles of Texas, which are currently freezing to death. A big thank you to all the volunteers who are working to rescue them.
Fascinating video! I would love to learn about the biologial plausibility and current progress of a Pleistocene Park
Dude... There's been movies about parks full of resurrected species...
It's hard to imagine how much the Earth has changed and all the things that have lived.
And things still to come. Will still be habitable for at least another 1 billion years.
@@coolbreeze2.0-mortemadfasc13 ehhhh 1 billion may be a stretch lol, itll be drastically different from what humans evolved to live in in just a hundred million, and by 1 billion the earths oceans will have largely been evaporated, and there will be practically no life left (as we know it anyway, who knows what evolution has in store lol)
It always freaks me out whenever i see normally small animals so HUGE.
Thank you all so much for making this program. I went to parochial school so my education did not have anything about evolution whatsoever. I get to learn and catch up with the rest of the population!
I'm just waiting for the day Steve makes a return...
I guess sea turtles decided, if it ain’t broke, don’t fix it!
Archelon had a skin shell, and the turtles that included the modern leatherback had a skin shell.
My body is so thoroughly calcified from synthetic D therapy (ie poison) that I also have a skin shell now! I literally can't even penetrate my thigh to do the injections I must do weekly anymore
@@detectivewiggles horrifying!
Thanks for translating metric. It's a blessing for us math challenged viewers.
Eons. Turtles. That dude... Everything is perfect
Eons and a pizza. The perfect end to a long Wednesday!
It's interesting to think that even if an animal goes extinct, it can still re-evolve from a different lineage.
And the Mississippi River is a geological image of the same phenomenon, interior seaway to continental dividing river.
That's convergent evolution for you. Even if a species goes extinct, if another species takes over that role and begins filling in the niches that once belonged to the previous species, it too will evolve similar traits and habits.
It's all about the ecological niche, amigo
How about an episode on the extinct Bluebuck antelope? I feel like there aren’t many high quality videos about this extinct species. You could relate it too how we can determine the genetic relationships of extinct animals with living species.
The Lion Turtle from Avatar is real!!!
I WANT TURTLE DUCKS!
Turtle Power!
I wish you're videos were 1 hour long 😪 I can't get enough of watching this channel, I eagerly wait for the new episodes every week and while I wait I rewatch all your other episodes. Its kinda embarrassing how many times I can rewatch your guy's content, but its just so good! I just want to show my appreciation (and literal obsession) for your channel, its one of the best of the best. Im so excited to watch you for many years to come 💓
I'm pretty sure I taught Archelon SURF at some point.
Carracosta
goodness! i've been lucky enough to see the very mold shown early in the video on display at the mote marine laboratory in december of 2020. they also had a mosasaur! truly a shame the exhibit was on its way out by that point
The quality of this channel is just brilliant.
I found this channel on Monday and I have already watched everything. Please post more videos! I would love to learn more!
Loving the outfit btw
Can’t wait to watch this - love y’all and what you do. Thank you so much for keeping us entertained AND informed 🥰💜💜💜🤓
I love thinking about the scale of some creatures from Earths history and it amazes me. Love getting more reference material like this to add to the prehistoric film I've been putting together all my life in my head.
I really like this host! He has a great balance of facts and humor!
Kelly and Blake make me think of me and my friend. I love puns and he hates them. I also send him frequently.
As Always I love your episodes! Thank you for making them. Stay well to all of you!
That joke reminds me of this (unfortunately not remotely paleontological) joke:
Q: What did Delaware when Mississippi lent Missouri her New Jersey?
A: Idunno. Alaska.
Buffalo buffalo buffalo buffalo buffalo buffalo buffalo
@@jstan5802 Except there's no Buffalo buffalo
I love this kind of thing (jokes at others' expense or dirty jokes leave me cold).
Reminds me of this classic:
'My wife's gone to the West Indies'
'Jamaica?'
'No, she went of her own accord!'
(I hope it doesn't only work in a UK accent! Otherwise just assume it's very deep!)
Props for the awareness at the end of the video
I mean considering the speed of Leatherbacks in water "Take Off" was actually appropriate
the tully monster transition is actually really cool props to the editor
finally!!! i have a plush sea turtle that i got when i was around 5 who i named archelon. i've always loved these big guys!
There's an Archelon skeleton at my local museum and it's a favorite for museum selfies.
That fossil display at the beginning is from the Thanksgiving Point museum of ancient life in Lehi Utah. It’s near my house and we have a pass there.
Can't wait to see leatherbacks evolving into crabs
Welcome back giant archelon!!!! ❤️❤️
Surprising sum of super sound science, all about the soft skin shell sea turtle. Thank you
Just commenting to support the channel.
This guy's presentation is better, than before. I don't know if it is the writing, delivery, or both. Practice makes perfect.
"I love turtles"
Thank you for making these extremely interesting videos!
Thanks for adding that text at the end, I had no idea! Much appreciated
is this the Gamera origin story?
Thank you very much for yet another great video. You are doing an outstanding job at sharing the fascinating history of life on earth.
Those turtles sometimes lay eggs in unexpected beaches, this new year one laid eggs in Los Cabos and it was a success, so at least 100 baby turtles were born recently 😄
Evolution is fascinating.The little bit of text at the end recognising the traditional owners of lands excavated for archeological purposes was cool to see.
You have tortoise well. (Ok, after that bad pun I will crawl back into my shell.)
Double pun! :D
Always great videos coming from Eons.
My favorite channel and my favorite animals
i love this videos thanks all incredible profissionals from this chanel
I’m always so happy when you are the host of the videos. You’re my favorite
last time I was so early in one video this kind of comment was funny
I love the transitions
1:10 don't be thinking that we missed this quick Tully Monster
what's with the Tully transitions tho? Am I missing a reference here? Are they planning a sequel episode about it?
@@deeya i do not know, but i would wager the tully transition is just for fun.
Turtles weren't the only things looking snappy in this video
love you videos so many things i never knew about these beautiful creatures
I love watching the show it makes me feel like a kid all over again
As to a turtle's takeoff: I saw giant sea turtles when I was in Hawaii. They were sunning on the beach at the line of where the incoming tide was just about to meet them. It only took one or two swipes of the flippers for them to be gone once the water overtook them. It wasn't exactly fast, but if you start the clock at when they were just barely "in the water", they did in fact take off rather quickly.
Amazing how nature and evolution just keeps churning out new species.
Convergent evolution is funky.
Huge respect for acknowledging native peoples rights
OK first, Editor, Love you in general. But also just want to give an extra shoutout for that pause in the music when the line "well as fast as turtles can" was said. Gold
Thanks for mentioning the muiscas! greethings from Colombia.
Aww. I forget how much I like this channel.
Gotta love the puns!
PBS sure has great stories to tell. :D
I'm glad to discovered this video
Very interesting content and good production ;)
