Interesting thing is that during the Triassic barely any time had elapsed since the various archosaurs had diverged. At that time dinosaurs and the various crocodilians and pterosaurs and such were closer related to each other than most mammal groups are to each other today.
In fact the divergence time for synapsids and diapsids at the start of the Triassic was only about 80 million years give or take. More closely related than Placentals and Monotremes are today.
I have to comment in support of bringing the intro back, one of the best intros I've ever seen regardless of how simple it is. Not seeing it on a Moth Light Media video has been so jarring for the past few months. Glad it's back!
I find the Triassic so fascinating, with its strange and diverse mix of animals. It definitely feels the most alien out of the three Mesozoic periods. Just a few years ago a still unnamed theropod dinosaur from the late Triassic about the size of Allosaurus was found in Scania in southernmost Sweden, along with several smaller theropods. It was the oldest theropod of this size ever found, and might suggest that dinosaurs were on their way to increase significantly in size already before the Triassic-Jurassic extinction event. And around the same time an elephant sized herbivorous late Triassic synapsid (stem mammal) was found in Poland. And considering the proximity between southern Sweden and Poland, it is possible that their ranges might have overlapped - so that giant theropods were hunting giant mammal relatives during the Triassic! There is still so much more to discover about this fascinating time period.
You always seem to find subjects that I didn't know about despite having consumed popular palaeontology for several decades now. Thank you for another great video.
@@alfaseng Only well known amongst paleontology enthusiasts in the last few years maybe, but I remember growing up that I read regularly about the end Triassic (I didn't even know this one was poorly known, it was.a pretty big fact I was taught that it occurred even if it was never focused on) or end Ordovician mass extinction yet I never even heard about the Great Oxydation event until just a few years ago
I’ve heard almost nothing about the dividing line between the Jurassic and Cretaceous and what caused it. Is it just poorly understood? What were its effects?
There's no dividing line between the Jurassic and the Cretaceous. It's the only geochronological boundary without a defined GSSP. There's no global extinction or geochemical layer to define one. The first appearance of an ammonite species is traditionally used as the lower Cretaceous boundary but that species has a limited geographical distribution, so it can't be used for a globally defined boundary. TLDR: the Jurassic-Cretaceous boundary is a WIP, it's mostly there for classification purposes because science needs to classify things.
how related some groups are should not be based on the names we put on them crocodile/reptile/dinosaur/mammal etc. but only on how long ago they had common ancestor. Suchians, dinosaurs and mammals are much more closely related to each other in the middle triassic than sauropoda, ornithiscia and teropoda at the end of the cretatious. This i think already solves the "one group" filling the niches problem
Small correction on 4:20 - dicynodont means "two dog tooth", i guess due to the shape of the teeth, similar to canine... canines. Great video otherwise, keep up the good work!
your videos are always a highlight for me - thank you so much for the highly enjoyable and greatly educational video, and all of the work you put into them
One thing to remember is the Permian extinction wasn't caused by an eruption, but a gradual heating of the planet. The Siberian Traps flowed for thousands of years, and wouldn't have created much airborne ash, aside from burning anything flammable. Most of the lava flowed into the oceans as well, which would have caused significant warming over time. An eruption, however, is short and cools rapidly, so it wouldn't heat the oceans much, but it does produce a lot of airborne ash. This doesn't explain how the food chain in the ocean wasn't interrupted, but perhaps the ash didn't obscure the sun over most of the ocean.
The Permian eruptions ignited coal beds, so there was both the volcanic activity, plus a massive release of CO2 from burning fossil fuels. Less than we are releasing now though, which is food for thought.
While dinosaurs dominated land ecosystems, they didn’t monopolize life as implied. Marine ecosystems were ruled by creatures like ichthyosaurs and plesiosaurs, while flying reptiles like pterosaurs coexisted with dinosaurs in aerial niches. This shows that the dominance of dinosaurs, while impressive, wasn't as singular as the comment suggests. Ecosystems were diverse, with various groups thriving alongside dinosaurs.
Hey buddy if that’s an AI thumbnail you gotta stop that. You’re one of my favorite paleontology channels on youtube but if you start using AI that’s gonna be it for me.
Please, I have been a fan of paleontology (though NOT a paleontologist; I love the NBA too, that doesn't mean I have ever been a professional basketball player or manager); I know about the big 5 extinction events, too much of a nerd to not know.
No group of animals have been as large or dominant before or since? Even lystrasaurus? Weren’t they thought to be 50% of the world’s fauna at their high point?
Flood Basalt Volcanism causing Supercooling at End-Triassic actually made much more sense. Due to Superwarming caused by Flood Basalt Volcanism at End-Guadalupian and End-Permian, the Ectothermic Sauropsids fared much better than the Endothermic Synapsids. With this massive reverse, the Endothermic Dinosaurs fared much better than the Ectothermic Pseudosuchians. Edit: So we know that: Superwarming - Ectothermic Dominance Supercooling - Endothermic Dominance With this knowledge in mind, a Supercooling event is needed in order to solidify Mammalian Dominance. MWAHAHA!!!
Search for "palaeoclima CO2 isotopes soil" and go through peer reviewed articles. I read it few months ago, unfortunately I don't remember the exact title.
SERIOUS ADVICE: Please , do not use AI for your thumbnails... It looks like one of these countless cancer channels on youtube who do not really care nor understand what they are talking about. At first i just said , nah fuck it , i will not watch it But i decided to rant at the bullshit in the comments , just because i hate these channels By clicking it was what i expected but this video was , to my surprise , really good and well documented , with real PaleoArts !
@@happy_owl565 easy answer. because every american knows there's ony wasteland outside the US and no internet. I'd say in terms of availability alone the audience of germany would already rival an american audience, after deducing the vast amount of US evangelicals who'd never watch such basphemous channels as this. if there are no statistics I'd apply orkham's razor and say he uses the comparison because the US would be a fitting size to do so.

Video suggestion: What are beaks, how do they work, and why do different animals evolve to have them?
They are modified teeth.
But I'm curious too.
"What are beaks? We just don't know."

I thought you were gonna talk about the Ordovician...
I was expecting the end Guadalupian extinction event
Mfw no Great Oxydation Event
@@sephikong8323 No that was pretty well known actually. End-Triassic, End-Ordovician, End-Guadalupian, and more minor extinctions are less known.

Gonna isn't a word
You could say it's the "Korean War" of mass extinctions between the Permian-Triassic "WW2" and the K-T Extinction "Vietnam".

one of the earliest sauropods *Schleitheimia schutzi* could be an interesting example for a future video about the early triassic :)
Thank you very much! These are wonderful videos.

Have you made a video about the Toarcian extinction yet? I think it's very interesting and important but not a lot of people talk about it.
The background music is back!
Thank you for this video! Almost no one talks about this extinction event!
Amazing video, as always
6:50 looks like the Giants Causeway here in County Antrim💚
Perfect timing. Thank you.

Why did you use Ai for the thumbnail?
i hope it wont happen again... it would break my heart if it was done with intent
00:11 the only thing stranger than the name Hatzegopteryx, is the animal named so
Can't wait for the video on the current mass extinction to drop (only a few hundred million years to wait).
🎉 a new video!🥳
Great vid as always but you don't need that ai thumbnail
How do you know it's AI?
If you were to scroll to this vid on Facebook, the first 100 comments would be people calling you stupid and that earth is only 6,000 years old
Omnivorous stem-sauropods were not on my bingo card. I should have expected this more though in hindsight.
nice video
Is there a term for animals like lystrosaurus that are the most prevalent vertebrates on the planet? Similar to bristlemouth fish in modern day?
AYOO NEW VID!
Always interesting to watch an MLM vid.
Polite, human voice, attributed art, paleobiology.
Can't be beat
I hope that's not AI on the thumbnail, please don't use AI images
End-Capitanian extinction would be interesting topic, too.
It always blows my mind how trees evolve too.
Sorry babe new mothlight just dropped
Great show. Actual conclusions from a broad history.
The Permian eruptions ignited coal beds, so there was both the volcanic activity, plus a massive release of CO2 from burning fossil fuels. Less than we are releasing now though, which is food for thought.
Cool
There is also the mid permian extinction, early Cretaceous extinction
I have heard of the end triassic extinction, but it is definitely not as talked about as the great dying, and the end cretaceous extinctions.
Let’s gooo
The Permian was still worse for land animals then the Triassic-Jurassic extinction.
Such a good channel!
Are there similar channels fans of this MLM content would recommend?
More on the how ancestral the archosaur trait of archosaur proto-feathers, pretty sure crocodiles have the protein in embryo but its not expressed

New Moth Light video drops, I clicks.
Do we have any examples of carnivorous Lystrosaurus? Why didn't they evolve carnivory if there was a niche available?
There aren't many end-Permian fossil sites (they're pretty much only found in Siberia and South Africa), so I assume there's a lot of unknowns.
Interesting how it was mostly the land and not much the sea.
Last time I was this early mammals still laying eggs
great video

Yo but the crocodilia are nested within the pseudosuchia... The graphic is wrong nooooooooo
I'll be okay
I'll be okay

Same with birds being nested within dinosauria.
Isn’t North America the largest continent? Pretty sure when all orogens are included it is, as Greenland is part of the North American tectonic plate.
north america(including greenland) is the third biggest continent

Is the narrator of this channel the same blond lad who does 7 days of science? His voice sounds so familiar.
How, specifically, are the co2 levels of this time period tracked? just curious
Search for "palaeoclima CO2 isotopes soil" and go through peer reviewed articles. I read it few months ago, unfortunately I don't remember the exact title.
Guessing before watching the video: it's trassic-jurassic mass extinction
I think there are only a few groups of poeple that are more likely to have heard about the end Triassic extinction than your audience.
