Figuring out what this creature’s face actually looked like would take paleontologists years. But understanding this weird animal can help us shine a light on at least one way for ecosystems to bounce back from even the worst mass extinction.
Thanks to Ceri Thomas (nixillustration.com) for the many excellent Triassic reptile illustrations (both Atopodentatus and Henodus) featured in this episode!

Yeah, it still feels wrong that they aren't mentioned at the end.
I wonder what happened to Steve, i hope he's okay

Fossil records makes up like less than 1% of all species alive, some things we simply don’t even know what they could even look like, anything living in jungles is effectively impossible to fossilize

Idk
Please come back!!
I miss the closure "and Steve!" so much
Unfortunately they had to scale back their contributions to the patreon, presumably because of the current pandemic and its economic toll.
ALL HAIL STEVE!!

It's official: George Lucas has a time machine. That's how the Star Wars animals were "designed", he just went back in time and reproduced what he saw.
did man discover the circle or create it?
Reproduced
Hummmm
or maybe Spielberg shared with him Paul's notes...
I've also been convinced for some time he also capitalized on a big time score with special effects.
Without computer capabilities, I doubt Star Wars would have gone anywhere.
Well this is why it says before the opening crawl... "Along time ago, in a galaxy far far away..."
Imagine how wrong some of our ideas must be about these animals. I mean, just take a hippo's skeleton. If you looked at it you'd imagine some monster from Star Wars, when in reality it's just a chonky water horse. Just think about how wrong a lot of our reconstructions might be without the actual soft tissue giving us a solid clue. Perhaps the Triassic creatures weren't half as weird.
I think of that often. Bones can only show so much. The face of a moose is kinda odd but you wouldn't know it from the skull. Think of a horse and its skull, would it look different if we had no known images or living species? How about a soft shell turtle or even better an owl. The owl looks like any other raptor sans feathers but its feathers give it a unique look. The Neanderthals look like primitive cave people bc the artist think of them that way but we really dont know what they look like.
@@olliefoxx7165 That is actually a miss representation of how the scientist reconstruct fossils. The moose would have its face, also for the horse and even hippos, guiven complete enough fossils. If the feathers of the Owl preserve, we surly could reconstruct its look to a certain degree (even its color now days).
Now with Neanderthals it's a very different story because they are our closest relative. We even could interbreed with them, and have their complete genome, so the best face we have of past species is actually the Neanderthal. We only need our modern forensic reconstructions techniques and genomic analysis to do it
Elephant skulls used to be thought as Cyclop heads in ancient Greece
I agree with shadowmax. Over the years, 'reconstruction' of muscle tissue based on fossils has evolved tremendously, also thanks to modern day scan techniques (e.g. for bone density and texture) and 3D computer drawing programs.
+MrMezmerized I still think it would be hard to tell what sort of muscular or cartilaginous growths there were on some creatures. An elephant, for example. A trunk is such a weird thing, and if we didn't have living elephants then it's possible our reconstructions of mammoths and such might end up having no trunks.
Same with us, really. Look at how many non-bony growths and weird special adaptations we have. No other animal has feet like ours, and it may be hard for another sentient species to accurately reconstruct that for a dead humanity. Look at our noses, and our ears. Hell, look at our gonads, those certainly won't survive to fossilize. On the minor end, they may misrepresent how much hair we have, too much or too little. They may only get a miraculous specimen of human hair patterns from a balding man's corpse and conclude we all looked this way since birth since male pattern balding is itself an a weird and unique phenomenon. Likewise, they may never know it existed because it wasn't preserved.
Maybe I'm just being a skeptic but I doubt we're being portrayed as anything but earless, noseless ape monsters, presumably ones who use their long fear hands to grasp tree branches while we swoop down and haul up a fresh kill with our forelimbs unless some remnants of human culture and depictions of us and our society manage to survive that long.
Actually, perhaps the Voyager is our best hope of being reconstructed, as it shows a man and woman, and that we come from earth. Granted they may think we were nudists, but it proves we were sentient and on the edge of spacefaring, if only they can find it out there in space.

Nothing really strange about Helicoprion's teeth. It was their jaws that were weird AF.
Insert obligatory british teeth joke here
Dude parasuars have a block of teeth in the middle of their mouth that their tongue wrapped around like a tumbler using it's tongue to push plants towards the middle of it's mouth back and forth I'd say that's another under the rader jaw weirdos

Atopodentatus immediately became one of my favorite prehistoric animals when I first learned about it. This creature's appearance is so fascinating, which is saying a lot considering what the early Triassic has to offer.
I may riot in the continued absence of our beloved Steve
Could you do an episode on taxonomy, phylogeny, and the tree of life, along with an explanation of when animals are considered two different species. And an episode on leviathan melviliai.
Aron Ra here on you tube has a 50 part series on that exact thing.
You expect that to be covered in one episode?!
@@LuinTathren no, I need lots of episodes. On everything.
that would be awesome!
@@larryscarr1929 Aron Ra can't get beyond his crusade to inform on anything.
This video literally taught me energy through a food chain in seconds while my science teacher be taking three weeks.
Don't underestimate how much you needed your teachers instruction to understand the brief overview.
Ask permission to send your teacher a link. Maybe...just maybe...it will be an excuse for the entire class to watch RUclips during school.
There are two things I really want to learn about right now: how did sharks turn into rays? My other question stems from your video discussing the Mesozoic marine revolution; Are there any niches that have gone away? Like ammonite or trilobite specialist perhaps?

Always so excited for your videos! The cadence of speaking, the way they make the material engaging, this speaker is excellent at what they do!
Triassic is just so weird I can't be surprised any more
Atopodentatus is proof that anything we consider common knowledge about a prehistoric animal could potentially become 100% wrong in the future.
proof that all 'scientific facts' are just the *current* observed truths, that can be challenged at any day. We are limited by what we can see, and we can't see everything.
@@deeya There are few or no scientific "facts" as science is constantly changing and updating. However, the more data, the less likely we are wrong.
The original depictions was not considered a fact though. It was just a hypothesis based on limited data
Can't wait until future paleontologists discover that it's all just barn owls.

where is he.
@@alucardnolifeking789 They did a vid a little while ago saying steve couldn't contribute anymore. It was a hard time for all. I just knew the time had come to an end when they were like andddd steve lol. Sad.
So genuine question, if we've only found one of a species, how do we know it doesn't have a birth defect?
Total guess, but, with modern wild animals, we would expect one with major deformities to die very young, so an adult would be less likely to have that kind of defect. Add to that the relative rarity of gross deformities in the first place, and it's reasonable to assume, in the absence of other evidence, that a given fossil is probably typical. There's a lot of "probably" in paleontology.
@@Amanda-C. so short response, it's unlikely, shorter response, we don't.

@@bradleywayne2788 oh shush with thinking how you say things is “superior” to others if the people saying it are American they say it the way Americans do, Other people say it how they want. pronunciation it’s also not exclusive to where you live so get off your high horse
@@sirsanti8408 No, the people who need to take account of what you say are Americans. The way many Americans speak makes it hard to work out what words they're saying, so this makes communication harder than it needs to be. This is the problem not the solution.

I love these representations of art of these certain species but it would be so dynamic and incredible to be able to see them in real life. It would probably change our outlook on these ancient animals and "dinosaurs" if we could see them in life.

I love it when I learn about a taxon that I never heard about! Though, aetosaurs are still my favorite herbivorous Triassic reptile. Aetosaurs - the "cro-cow-diles."
I love when PBS eons posts a new video! It shows animals from the past and learning from them! Merry christmas!🦖🦕

I remember reading about these in grade 2. They where my favourite marine reptile because of their face. I thought they where ADORABLE
Every time I see these preserved fossils
I can’t see any details so props
To the people who know what they’re looking at
You guys should do the weird marsupials from Riversleigh in Australia.
Strange but fascinating. Never heard of this animal before. Thank you.
Every time you guys mention "the great dying" it sounds like something taken from the land before time or something

Wonder if you can do a video about evolution of the kidney? We would still be in the sea if kidney didnt have the ability to retain salt.
Thank you PBS Eons!
Fantastic content! thank you for making these!
8:36, thank you for pronouncing niche correctly after doing it how you usually pronounce it. My ears were pleased.
all the marine reptiles are such an amazing mystery. Id like to know more about their detailed looks. like, since they had to evolve past their cold blooded nature, did they outwardly resemble convergent fatty tissue appearance like whales and seals? or were they still scaly and looked totally new and different, like some sort of chubby thick crocodile. The idea of reptiles being big ocean predators seem terrifying, since reptiles are so bloodthirsty and non-empathetic.
I love PBS Eons and melodysheep. Absolutely amazing channels one is for evolution and the other for space
I really love your channel! Can you make a video on Monotremata (Platypus)? one of the most strangest animal that still exist
3:23 *unusually intense meditative music starts*
So weird and so cool; makes you appreciate this magnificent world of ours
Please make more videos on evolution of plants and palaeobotany. Truly love your content.
You guys should do a host vs host episodes, where you pick a topic and then compete to pick the best creature to fit that topic, example, cutest burrower, weirdest looking glider, or funniest mating rituals. And the viewers get to vote for the winner. Could be really fun.
Wow, every time I think I've read, heard, seen the weirdest find after the mass extinction event,...what the?
