Check out Bizarre Beasts! • The Bizarre Beast with...
At more than 2 meters long, Aegirocassis was not only the biggest radiodont ever, but it also may have been the biggest animal in the Early Ordovician. This bizarre marine giant may have only been possible, thanks to a major revolution among some of the tiniest organisms in the world.
Thanks to Franz Anthony (franzanth.com) and Ceri Thomas (nixillustration.com/) for their excellent radiodont illustrations featured in this episode!
And special thanks to Peter Van Roy for providing us with those excellent Aegirocassis fossils!

Mr. Radiodonts
This joke makes canonical sense because radiodonts eventually became arthropods, and thus crabs.
If Hillenburg was still alive and still had control over the show, it seems like something he'd throw in there. Something about how even Krabs' and Plankton's ancestors were at it.
@@redeye4516 Radiodonts belonged to Arthropods and they went extinct - they didn't "become" anything, and especially not crabs. They are more like... long lost cousins?
So what we've learned today is that these things, in fact, were NOT things that evolved into crabs
FAKE CRAB REEEEEEEEEE
Maybe that's why they're extinct, didn't follow the trend. Now, imagine a giant whale crab.

@@LimeyLassen anything related to smoked is definitely delicious
Ah, sounds like you accidentally classically conditioned yourself! I too have often accidentally formed a permanent association with a memorable situation and a strong olfactory sensation.
My current favorite I formed last year would have to be baking spicy "chicken fries" while watching 90s toonami shows on a frigid winter night. Now whenever I see an older anime I immediately crave spicy chicken fries (specifically the aroma of baking the frozen ones at home), or vice versa. I also get the impulse to put on a sweater or blanket. The human mind is wild haha

@@aguy01 Agreed.
So that's why the sea is essentially plankton tea?
@@MrAranton the sea is a giant soup. Its full of fish, plants and salt.
@@badideagenerator2315 But can there be a plankton revolution without a planton tea party?
Plankton will do anything for the Krusty Krab recipe.
Being large like that also provides an advantage of being too big for most predators, so rather than spending energy on fleeing and requiring the ability to move quickly which would only be useful for a suspension feeder as an escape mechanism, they can just sit there and keep eating. This is also a huge part of why suspension feeders like basking sharks and baleen whales are often the largest members of their clades. Perhaps Aegirocassis became larger as part of an evolutionary arms race against a currently unknown (or maybe known) apex predator that evolved around the same time.
The way that filter-feeders sometimes get so huge is amazing to me. It's like they turned hunting into a statistical exercise. A cheetah for example, either catches its prey or misses it entirely. 0% or 100% success. But a filter-feeder can catch anything between 0% and 100%. The cheetah eats like a king or not at all. A modest filter-feeder eats like a cobbler, but it does so every single day. Combine that with lots more food, and you're eating like a king every single day.
Quite similar to plant eating animals then I think right? They also mostly eat big amounts throughout the day and are basically constantly eating
Thats why they get so huge. Whale shark is genius.
@@bongo2282 yup! thats always been my thought as well. If you eat meat you get to spend less energy on digestion of course, but a herbivore? your food doesnt run, and if theres alot of it in a area because noone else eats it yet its just basically asking to sit down in your range and get humongous. All you gotta do is figure out what funky digestive method youre gonna go with (4 stomachs like a cow, feeding off the bacteria in your gut for protein while feeding the bacteria the plants like a gorilla, etc.)
A cobbler? You mean like the pie?
@@walrusArmageddon A shoemaker. It eats a humble diet.
This is a weird thought, but surely the early Ordovician is the last era where you could wear a diving suit, leap in the ocean and win any fight with any creature. I mean, there’s no sharks, killer whales or ichiosaurs or whatever.
You would lose the fight with the atmosphere tho

К тому, у неё такой приятный голос. Просто удовольствие.
I was so hangry until I clicked on this video, and hearing your voice instantly changed my mood. I love this channel, and I want to give everyone who works on it a giant hug.
That animal almost looks like a spaceship, I never knew anything on earth looked like that. I think that's what I really love about this series, sure there are all the popular animals like dinosaurs and Eocene mammals, but it's also one of the few series on TH-cam that can show me things about life that genuinely surprise me, and that's awesome.
We actually had an internal "That looks like a Star Destroyer" chat on Slack about this :D
Underwater creatures really look like alien forms
I instantly thought the same thing, it looks like those weird spaceships that adorned the cover art of paperback science-fiction novels in the 1970's
Anomalocaris was once thought to be 3 different organisms, but it turned out to be 3 parts of one animal.
Reminds me of that metaphor about 3 blind men trying to identify an elephant.
One was feeling the trunk, and concluded "ah, l know. It's a snake"
One was feeling a leg, and concluded "ah, l know. It's a tree trunk"
One was feeling the sides, and concluded "ah, l know. It's a wall"
Really shows how mistaken you can be when you don't have all the information, and make your judgement too early.

Man, I love Radiodonts and the idea of a giant crustacean whale sounds amazing!
Keep up with the great work, Eons team!
Giant Crustacean Whale is the name of my new band
Its a technicality but radiodonts were stem arthropods that diverged earlier forming two rows consisting of finlike flaps and finlike legs. True arthropods are defined by the fusing of the swimming flaps/fins with their legs to produce far more robust limbs at the cost of the ability to swim. So radiodonts while closely related to true arthropods represent a sister group to the true arthropods that adapted for life in the water column above the seafloor rather than living on the seafloor. So they definitely aren't crustaceans as those are a subgroup of arthropods.

I always feel like a time traveller when I am watching your channel. It was a very informative and visually impressive episode again. Thank you.
1:25 It's carrying a newspaper.....
"Why wouldn't these creatures just get larger over time?"
Because they're arthropods. They likely had hemolymph instead of blood, which significantly impacts the size of the creature. It becomes extremely difficult for them to move if they're too big when compared to oxygen available in the environment, and iirc the oceans weren't particularly oxygen-rich at the time. A giant filter-feeder doesn't have to really do much more than float around, though, so it doesn't NEED to be capable of moving quickly, so that downside of hemolymph wouldn't really affect them as much.
...At least, I think that makes sense. Having typed this comment out, I feel like it's definitely grossly oversimplifying things, assuming it's correct. There are people who know more about this than me who'll correct me though, probably.
Also very oversimplified: They have exoskeletons. Those are also quite a challenge for growing big.

Another excellent video. Thank you for continuing to acknowledge the indigenous peoples whose lands these fossils have been found on.
Huh? Why does that matter...?
I wanna thank you for the strange and unconventional size comparisons, as it's easier to visualize and make real in the mind "about the size of a shoebox" than some numbers. At least for me, anyway! Thanks!
PBS answering more questions I don't even know existed. I'm thankful tho.
An an entire episode dedicated to my favorite fossilized friends, the radiodonts.
Yes, this is a wonderful day.
I love how you recognize the people's lands and cultures where the fossils were discovered, like you do on a lot of your videos. It's respectful to these people and informative to us! 8:35 for those who didn't understood about what I'm talking about.

This channel has help me discover my love for paleontology, only to find out that my country doesn't offer proper education under that topic at any universities :(
No worries - you can easily get into professional paleontology with a university degree in geology or biology. You don't actually need a paleontology degree, at least at bachelor/undergraduate level. Once you're at Master's/Ph.D level, you can choose to specialise into something closer to paleontology. But even for those post-bachelor degrees, many of them aren't paleontology, but rather "evolution", "evolutionary ecology", "systematics", "paleobiology"...
If you have any other questions about getting into professional paleo, just ask. :)
As someone currently doing graduate work in paleobotany, getting a good feel for geology and some biology experience (like a geo major and bio minor though I don't know how your countries academic stuff works exactly is a great set up for this sort of thing. Heck even at the graduate level (Masters/PhD) often you'll see people's degrees labeled geology, geobiology, paleobio, etc and not "Paleontology". Basically paleo is a diverse field so often it doesn't have a clear path to it.
@@christianv-h3278 are you a palaeontologist ? If yes how is it
@@christianv-h3278 Thank you so much for the optimistic response, I'll look a bit more into it
With an earth sciences/geology or biology bachelor you can easily get into paleontology. Earth sciences with a focus on sedimentary geology, stratigraphy, biogeology and/or paleoceanography (there's a lot of overlap between those fields) would be ideal. In my earth sciences bachelor there were only two specific paleontology courses and that was perfectly fine. I'm a biogeologist/paleoceanographer, so I look at the ocean throughout geological history. During my studies I mostly looked at sedimentary rocks and microfossils, but now I mostly do modelling. I do know several people who did almost exactly the same bachelor as me that got into actual paleontology (like literally digging up a T-rex, haha).

"They kinda looked like lobsters!"

Lots of Spongebob references in these comments. Makes me wonder what the Cambrian equivalent of each character would be like. Ironically Spongebob himself would be exactly the same.
