Trilobites are famous not just because they were so beautifully functional, or because they happened to preserve so well. They are known the world over because they were everywhere!

I just know that one day a submarine will be trawling the depths of the sea when the lights will flash across something crawling along the sea floor, the pilot will aim the lights back over the spot to see a little trilobite just scuttling along and we will know that they are truly the greatest survivors.

Honestly, I have more respect for trilobites than the dinosaurs or even fellow mammals as survivors. They didn't need to become towering giants or legendary predators, they were just little toughies who were only wiped out by the closest event to the actual apocalypse that the natural world has ever known (with the ancestors of the dinosaurs and mammals only _barely_ surviving it, and they weren't even already on the ropes like the trilobites were). Rest In Peace, bold bugs. Hopefully, when reviving extinct species has been mastered, they'll be among those brought back again for round two at what they do best; adaptation and survival.

This combined with PBS Space Time just brings back good memories of old Discovery Channel. Before it got filled with ice road truckers and deadliest catch. Back when new sciences were being shown. When all the fun channels like History, National Geographic, Animal Planet, all had fun to watch and educational shows. Good Job!

[@richardcramer1604]

A Diabetic Jedi, I agree the Discovery Channel and History channel were great in the 1990's and early 2000's but then to save money they started putting all those boring reality TV shows. The only saving grace was The Universe series but when History started showing Ancient Aliens I jumped ship.

[@metanumia]

Yes, I agree with you guys. I used to watch Discovery, TLC, and History Channel as a kid in the 1990's. History Channel should now be called "The Pseudoscience and Conspiracy Theory Network".

[@IamMissPronounced]

Anodyne Melody it's become an entertainment channel rather than an education channel, which is understandable seeing that the demand is very high in entertainment.

For learning more things like this, I would highly recommend anything from SIr David Attenborough.. He has a great 2 part series called "First Life" which goes in good depth on early life on this planet... Just do a search using "David Attenborough's First Life" He has so many docs out on life and animals... Great ones.. He's been doing it for over 50 years...

I'd be curious to hear a hypothesis on why the horseshoe crabs survived and went on to live to this very day when the trilobites did not. They were similar animals presumably in the same niche. Maybe their reproduction cycle was vastly different? Did laying eggs on the shore help?

[@LimeyLassen]

Or their mysterious blue blood

[@d3str0i3r]

they evolved from a creature that had more than just armor, iirc the sea scorpion mainly prayed on trilobites

[@alvarogoenaga3965]

@Desmond. If that is the case, you could say that horseshoe crabs (rather their ancestors) contributed to the trilobites' demise.

[@vguyver2]

It's rather interesting in that in their debut as a species, Trilobites were one of, if not the top predator for a period of time. By the time they died out, they had become one of the most bountiful prey in the ocean.

[@ottosantiagolassus]

I was thinking the same thing, I truly thought Horseshoe Crabs were their descendants

[@Lazerblade95]

So glad this is happening.

[@indigoray6693]

Richard Kaskiewicz you're so glad what's happening?

[@indigoray6693]

Jess Vermont and what did you mean by you're having trouble with their trilobites and hoped nobody noticed what? Lol sorry I'm just a little confused on what u mean.

[@LuisSierra42]

Richard Kaskiewicz, What, another massive extinction?

[@eduardoleva9842]

Extremely well explained! Gracias!

[@davidp3394]

It's so awesome these videos that tell us the story of other animals that lived like us now

[@yourdailynoob5828]

my mind is now heavy with the sad history of the trilobites 1 like 1 chance to the trilobites be cloned

[@brooksanderson2599]

By 2026 humans will join them according to Guy McPherson. No need to thank me for that info. Sleep well. old geologist

[@regularfather4708]

Trilobites must be cloned!

[@bemusedbandersnatch2069]

...cloned how? Cloning requires DNA. They died off many millions of years before the dinosaurs. Furthermore, what remains we have of them are all fossilized. We can clone mammoths because we've found mammoth bones and I think a frozen mammoth or two (Google says yep, that's a thing.) Jurassic Park came up with the hypothetical process of cloning dinosaurs from dino blood in a fly in amber (which I think is impossible given the lifespan of DNA but I digress). But...there's nothing from that far back that left any biological material behind that I know of. It'd be like trying to clone a human from a photograph. So, we'll whip them up from scratch someday once we finally commit the greatest blasphemy of all and start cooking up brand new forms of life for our own amusement. EDIT: And after I wrote this silly comment I went 'a googlin' on the subject because I was curious. Apparently some team managed to analyze a 500 million+ year old fossil and figure out that it had cholesterol and was thus an animal. So apparently science is even more crazy awesome than I thought and maybe we will have cloned trilobites someday. Who knew?

[@yourdailynoob5828]

only the future knows...

[@bigsouth010]

I’ll have sex with a trilobite

[@ginckgo]

Regarding the ability to enroll: this may not have originally evolved as a defense against predation, but rather to improve their ability to moult. There are fossils of trilobites that died in the middle of moulting, apparently getting stuck on the way out of the old exoskeleton. Being able to significantly flex their body up and down probably allowed them to dislodge from the old exoskeleton much more easily. This flexibility could later be coopted to fully enroll as defense

[@Maevenish]

My favorite animal group of prehistory. Love the little guys!

[@RollingMoose]

Damn, it took me two years to realize that the title of this was a star trek reference.

[@_Mentat]

Tribble will never go extinct.

[@AstoundingChaotix]

Let's see here... Star Trek reference. Trilobites. Factual information pertaining to said Trilobites. Correctly utilizing the word "Eons". Hank Green. Subscribed!

[@abhiramsrivastava4601]

AstoundingChaotix what was the Star Trek reference

[@borismatesin]

The title is a reference to a Star Trek (The Original Series) episode "The Trouble with Tribbles". Cute creatures, multiply like crazy and, in the end, get wiped in an instant.

[@gummihu]

Damn, didn't catch that

[@Edgewalker001]

Not so much "An instant", the Klingons had to assemble an armada to destroy the Tribble homeworlds after all, and then round up all survivors... =p We never did get to know if they have any songs about the great Tribble hunt...

[@dangerouslytalented]

Also diet of worms

[@kingpotato7183]

I feel for my trilobite brothers #prayfortrilobites

[@rollomaughfling380]

04:33 That is one seriously goth trilobite

[@soulmass8904]

I found a small one of these on a hike when I was really young.

[@camdenhill7651]

I'm already Digging this

[@abhiramsrivastava4601]

Camden Hill I'm already hating you for that joke Naw jk bruh 😂

[@pbsvoices]

ba dum chiii

[@Infernoraptor]

I dig it like Diglett

[@metanumia]

Hope you find some good fossils. ;)

[@ayior]

I am so deeply fascinated by this. And so far all I did to satisfy this fascination was ocassionally browsing Wikipedia. Now I have it in video form and this is my start of watching every single video of this channel in chronological order!

[@jeffsiegwart]

Nice Job! Thank you.

[@qgisforgeos]

Awesomely presented the great dying.. I loved it truly .... This gave me the new vision to look towards the trilobites... Thank you soooooo much for this video...

[@zeramino]

This series is so exciting!! and so very well done (so far) as well. Thank you all for informing and entertaining us!!

[@Sheogorath2077]

i wish trilobites still existed

[@raver4lyfe16]

Horse shoe crabs are pretty close

[@mdawson8386]

They do still exist just as fossils!

[@randybarnett2308]

Sheogorath2077 me too I wonder if they taste like shrimp?

[@peterrobinson7803]

Really like a more detailed examination of cambrian oddities other than Anomilocaris and trilobites. Love PBS Eons!

[@animeobsessee2125]

My favorite person to learn science from!!

[@geoffrey3668]

Awesome serie!!! Thanks to bring quality show on KZbin!

[@BingeWatchers]

This was fascinating, I guess this goes on the weekly watchlist with all other Complexly shows!

[@johnishikawa2200]

Whenever I see horseshoe crabs I think about trilobites . Horseshoe crabs have blue-green color blood , and I have seen many of them moving seemingly locked together in a raft formation , in the shallows just about a foot below the water surface . I believe that they are laying eggs near the beach . But there must be thousands of those horseshoe crabs in that raft of them .

[@charity4613]

this might just be my favorite youtube channel!

[@pimpminya7131]

Hank Green, PBS, and Prehistoric life!?! This is the perfect KZbin channel!!!
