Prehistoric Underwater Pompeii | Pristine Trilobite Fossils Reveal Unseen Anatomy
Вставка
- Опубліковано 7 лют 2025
- Trilobites are some of the most common fossils throughout all Paleozoic rocks. They lasted for nearly 270 million years, producing 22,000 known species. They were extremely successful members of the Arthropod group, with some collections of their fossils making up the majority of clasts within a rock - biology that becomes geology. With so many of them known from so much of earth’s history, one could be excused for thinking that scientists know all there is to know about them. Yet, groundbreaking things are still being published about these commonplace creepy crawlies, one such discovery finally puts a giant nail in the big fat coffin that is the mystery of what the guts and mouthparts of Trilobites looked like.

It's wild to think it'll be another almost 20 million years until trilobites have been extinct for as long as they were around.
yes it is 😊
Like Jack Black...
Deeeep thought....
Luckily I just finished my 1st cup of coffee
Good Job on the logo! I woulda passed this video up if it wasnt for all the colors. this is my first video of the channel, but imma subscibing.... to think i woulda missed it without the yellow or the blue. Thumbs up!
Gotta love the overly emphasized “sphhh…”on “sphincter” legitimately made me laugh my dude!😅👍😉
I have two beautiful trilobites I bought from a Canadian fossil vendor. They’re Burgess Shale units and are prized parts of my fossil collection. Can’t recall their individual names right off the top of my head, but they are treasures. My grandson has already laid clams to them when I’m “finished” enjoying them. Another trilobite fan in the family! 🇨🇦🖖🏻🇨🇦
I have found some crinoid disks fossilized into fool’s gold. I was fascinated but couldn’t find much info on how it happens. Thanks for including info on that.
Went fossil collecting in the Trilobite Wilderness Wildlife refuge in San Bernardino County, California many years ago. Fun adventure of my youth.
Lots of interesting new info here - thank you very much!
Love ya videos man, never stop helping us learn!
I always wondered if either the mass extinction caused most if not almost all copper blood creatures to die or if it made the few who already existed more likely to survive...
I myself really want to believe that the cambrian was filled with blue blood creatures and that was the main cause of their extinction...iron was slightly better than copper...
That doesn't explain all the copper blooded animals that survived tho
prob one of the best preserved fossils tbh
4:05 Nevermind the trilobite, what the hell is that moving in the upper left? That hardly even looks like it should ever have been alive!
A weird early echinoderm.
@@EDGEscience Takes quite a lot to be weird If you're already an echinoderm, I reckon 😅
easily the weirdest things we even remotely related to
Underwater pyroclastic flow aftermath....this like a Paleo goldmine
They actually have a special name for sites like this - Lagerstätte - and yes they are literally gold mines for studies.
Excellent presentation. I always found the variety of trilobites in Morocco to be the most interesting visually. The examples I own are nothing compared
Amazing! I think we tended to think of evolution as a kind of approach toward perfection, down through the ages, but it's clear that every organism always was perfect for its niche and time.
yeah, evolution isn’t about striving for perfection; it’s about adaptation to specific environments and circumstances
Agreed. Evolution isn’t about perfection, it’s about “good enough”.
I've never thought that 🤔 For me i've always seen it as animals just trying to survive and changing to make sure that happens 🤷🏻♀️
Love this intro
Expanding the knowledge of Trilobite just for the thrill of it.
I've always wanted a Trilobite fossil
The roly-poly bugs look an awful lot like trilobites.
great to see new info about these prolific critters. Unrelated question - what is the crawling nightmare 'derelict spaceship' looking creature at th 4 min mark, a primitive starfish? Never seen that before.
That was an extinct echinoderm species . You sorta guessed correctly.
Cothurnocystis species
So they ate just like horseshoe crabs! The whole body plan is pretty similar at that.
Definitely interesting and a really cool fossil but I guess for me it's not because it's boring (not at all i've loved dinosaurs, fossils, and prehistoric things since I was a little kid actually wanted to be a paleontologist at one point and trilobites are one of my fav prehistoric animals) but more so because there's *A LOT* of living animals that need our help due to our own selfish actions (and animals we made extinct we could and should work on bringing back) so to focus so much time on extinct animals (that we played no part in making extinct) seems kind of silly to me when it's over things like this because obviously they ate, pooped, had sex, etc or else they wouldn't of survived for as long as they did (having interest in and love for prehistoric animals isn't wrong i'm talking about these really deep topics like how they moved, mated, ate, slept, etc). Now once we make sure all of our living animals are safe, bring back animals we made extinct, and/or studying ancient animals helps us to understand modern animals i'm all for it but until then I feel like our deeper focus should be on living animals because if we keep on the evil selfish path we're on they'll all be gone 😕
Or we could do both.
Garlic, olive oil, salt, pepper and a dash of oregano.
@@iTsEfFiNsTePhh No. It's not the job of humanity to bring back something that's extinct. 99% of everything that's ever lived is gone. We're obviously not good at playing creator when we can't take care of what we've already got.
I hope they find a marrella’s fossil in this group
A very tiny monster!
what animal is on the top part of the screen in 4:04? it looks unsymmetric and have limbs it seems
In the intro, top left, is a strangely asymmetrical animal. What is that?
Weird early echinoderm Cothurnocystis
@@EDGEscience Can you do a video on that ?
They had antennae?
Antennae and cerci!
And cruise control....
@@NV..Vspoilers too, on the sportier models.
How could they have died with their stalks pointing up? Woudnt it fall down if they died?
Their stalks are covered in their exoskeleton and are rigid. Not like snail eyes.
More like Primordial Sushi or Barbecue time !
Arthropod, poo tube, bet they would have been tasty, think massive shrimp.
Trilobites stay winning on God bro
this is science. ain't no place for your god here.
@@cliftongaither6642 not even Terrence? The trilobite deity?
