We have since built museums to celebrate the past, and spend decades studying prehistoric lives. And if all this has taught us anything, it is this: no species lasts forever. -Kenneth Branagh
Unfortunately, too many of certain type of person uses that sentiment as an excuse to continue creating our own mass extinction event. They same to think it's normal.
Thank you for sharing this content. It includes more detail about the Siberian Traps activity and timing of its consequences than I had previously encountered.
Thanks for making your paper available for us. I wish I could give it an honest grade, but I was a professor of music, not palaeontology, so I'll just satisfy myself with learning from it. Thanks also for making such a wonderful channel for us all to learn from and enjoy.
Incredible content, as always. One observation, suggestion though. Could you please include maps of the continent positions both currently and in the time periods being discussed. It would be very helpful in visualization distribution of species as well as geological formations .Thanks, and continue with your exceptional work.
This is the best, most comprehensive explanation of the Great Dying I've ever heard. I usually have to watch at least twice to absorb everything. I'm slow. You are my favorite TH-cam site.
The Permian extinction was sad of course. But if it never happened, the world would never see the more special organisms in the world's history: the dinosaurs.
Maybe because I’m saddened by the loss of so many animals throughout earth history, I find these presentations particularly interesting. The Great Dying is an event that deserves your level of focus. An excellent presentation.
Somehow, I am thinking your coursework for degree is going to be an A, if it is even half as good as your channel content, well disserved. Very well done to give prospective to the history of life VS. modern times. Good luck in your studies, but you will go far no matter what you pursue. 👍
Another excellent video, Ben. I especially like that typically, you guys share new insights or research with a measure of modesty. What I mean to say is, too often paleo-themed YT channels, blogs, tweets, etc., will jump onto every new bit of research or hypothesis or theory and excitedly proclaim it as a new “truth” of discovery. Of course, such information may eventually come to be accepted to an assumed truth given the evidence, but science doesn’t deal with absolutes-it deals with falsification and probabilities. So, even though it might seem like a very insignificant detail, just using small words like “might,” “maybe”, “possibly”, “perhaps”, “could have”, etc., when speaking of the possible conclusions such evidence or research or hypothesis might lead to, helps to remind the viewer that not ever detail about every subject is always known for absolute certainty. (Hence the reason for continuous research!) That is simply the very nature of the historical sciences, and I much appreciate that you all generally are good about doing this. It’s important for the scientific process to be as transparent as possible for the general public, which helps to clear up a lot of misunderstandings as well as to explain exactly why and how we draw the many conclusions that we do. So, good job, lads! -A Paleontologist
Yeah, there are WAYY too many "science" channels out there that are run by people who are scientifically illiterate. (And I include most science journalists in that desciption). But you dont have to have trained in the sciences to be scientifically literate... you just have to be able to review a paper and analyze the methodology. Is there a large enough sample size?if there is experimental data, how were the experiments constructed? was there a proper control? do the claims of the authors actually match the data they collected? how weak or strong is the hypothesis? are the results within the margin for error and therefore too weak to support the conclusion? Etc. And of course, like you said, the realization that science is a constantly unfolding revellation, not a dogmatic Truth... as well as the realization that nothing in science is taken as fact until the results have been independantly verified or reproduced. One paper doesnt change everything by itself.
@@patreekotime4578 yes, exactly. But these facts are either a) not known/understood by most people, even those interested in science, or b) such persons are too lazy/lacking the training in critical thinking to scrutinize the data. Just because something appears in a scientific paper doesn’t mean there is no misinformation in it or that the authors didn’t make any mistakes. That’s why science is a communal effort. No one person can know everything or change everything. Even so, many science enthusiasts (especially it seems those lovers of paleontology), sometimes act more like the “fans” of a movie/book/TV franchise, treating each new piece of data like a “leak” from the studio and speculating about the next film or season. The enthusiasm is appreciated, but we must approach science and fiction differently. How many YT videos are out there that called “What X dinosaur really sounded like” or “Allosaurus’ Sounds Reconstructed” or “new discovers turns the field on its head!” Besides the fact that no one can reconstruct the sound of an Allosaurus or that very rarely does a single discovery “rewrite history”, such videos give the false impression that we have everything figured out, that nothing is forever unknowable, or that science is a straightforward venture. Any reasonably modest person who has ever gone through proper scientific trainer or even just been very well read will tell you: the more you learn, the more you realize how little we actually know, how much more there must be to know, and that most everything-past, present, and future-will forever be unknowable. In other words, humility is essential for doing good science, and that goes for those reporting on the sciences as well.
This is so cool! To be able to get hands on your newly published work is such a treat. I really dig* your channel, and even though I'm not in this field, I appreciate the love and care you have for science. Cheers from a musically educated paleontology enthusiast.
Great job! Would have been nice if you included the capitanian extinction at the end of the middle permian. A lesser known extinction event during the permian.
What an incredible article. I’m doing my master’s currently right now, this paper totally looks like one I would cite in my own writing hahaha. Very well done
Good Job there, I can see your work in Africa doing you good. Now as an old-time geologist/planetary scientist, I do reserve the right to softly laugh at two digits after the years (251.48). Still, heck you guys might be getting close on that (its been close to 50 years since I did any straight-up geology, looks like you have been carrying on excellently). I would love to see you make a Siberian Traps series, I think that it has a lot to say. Once more, good job. Oh I was one of the contributors to your African studies, I think it was clearly money well spent.
First video of yours I'm seeing and I absolutely enjoyed it. Your voice is great for this and your articulation is superb. I look forward to watching more!
First time I have seen the information about the underlaying geological landscape prior to the formation of the traps. In a lot of ways this sounds like what would have become a major coal deposit explaining just how much carbon could have actually been released beyond just the volcanic events.
I rememeber telling my best friend about this event that he had no clue about, I barely showed him the wikipedia article and as he went through the various environmental changes, one by one his face turned from "whats this all about?" to outright "HOLY FUCK!", needless to say I couldn't stop laughing at that expression.
"I've stood on this boundry." Ben stood before the scene of carnage. Ash blanketed the landscape as UVR bombarded the earth through a destroyed ozone layer. Nothing stirred but the wind blowing streams of ash and cinder into the air. They were standing on aftermath of perhaps the most terrible event in the history of life on earth, it was awefilling and terrible at once. But heartening to know that no matter how bad it was now some things would persevere. Life would continue. Eye-patch Doug stepped up next to him throwing up clouds of volcanic ash with each step, skin greasy with sweat and sunscreen. "I love the smell of volcanic ash in the morning," Eyepatch Doug said through his respirator, he stopped for a moment considering the scene with satisfaction, "it smells like victory."
Life had experienced mass exctions before but those exctions were largely unicellular. This was just the first time that larger animals were put through the grinder. Everything after couldn't be as severe cos by definition they were the survivors of that great dying
Can someone explain the part about only 2 mass extinctions effected plants and only 1 severely impacted insects? Is this the consensus view, or is this the only a "based on the limited fossil record"? Or were there actually a bunch of large insects familys that died out during the PT extinction?
Thanks, I studied this 30 years ago and there was so little known about any of this and it was also fashionable to have asteroids do all the mass extinctions as well lol.
I suppose that the sheer size of the Siberian trappes contributed to the Permian-Triassic extinction. The igneous province was gigantic, considerably larger than the Deccan trappes, which was also quite large. The size of the trappes is probably proportional to the length of time of the volcanic activity, or at least that is a worthwhile conjecture.
Love your channel and the great clarity and style of your presentation 😁 Where exactly in South Africa did you visit that boundary layer? I live in SA and need to plan a trip there! Looking forward to watching the SA series of videos 😊
No, our atmosphere has changed composition by good percentages over the eons. We have access to gas trapped in rocks etc, but don't have a good way of telling if we had holes over time. Given how the holes we have had changed over a few decades= hard to tell
Wouldn't say that: just doesn't get explained step-by-step well. Hard to dig into a topic when you're focused on work/survival. Don't assume you're unable to learn it, just a matter of time needed.
Imagine the thousand of animal generations living during this apocalyptic wasteland that lasted for so long. If they were sentient do you think they would have any hope for it to end?
Which forms lived through this and how did they survive? Also, showing Siberia as it exists today and the extent of the Large Igneous Provence sure is useful, but this video also needed to show the LIP as it related to Pangea, the shape the continents were in at the time of the "great dying".
Quick question for you or anyone else out there.. Are the Siberian traps the same pierod or event called the Decan or Dican Trapps or Traps, which I think were around India... Involving 10 kilometres of Basalt lava fields... Are they of the same epoch? Are they the exact same thing? Many thanks in advance fo anyone responding! Regards
to state that ~90% of species died is actually underestimating the carnage it seems pretty obvious that of the ~10% surviving species they themselves loss ~90$ of their living individuals that would result in about 99% death of all living organism for the whole event
I long subscribed to the Siberian Traps LIP theory as the likely cause of the P-T boundary event. Made perfect sense to me until I heard about the probable crater in Wilkes Land Antarctica dated roughly to the end of the Permian. The Deccan Traps LIP was active during the K-Pg boundary. Some suppose the Chicxulub crater and Deccan Traps are connected events being approximately antipodal and coincidental (search for antipodal focusing of seismic waves). If the Wilkes Land formation to be an actual crater, it's 2.5 times the size of Chicxulub and indicates a bolide about *30 miles* in diameter. Accepting all of this to be true, where would the antipodal location of an East Antarctic crater have been 250MYA? More importantly, what level of devastation would such an impact cause...?
I believe the combination of such a huge asteroid and the huge eruption of the Siberian Traps were why the extinction was so bad. With life already under pressure from the asteroid, and then getting kicked while they were down by the volcanism
It’s been downgraded from a probable crater to a possible crater after greater review, and there is no conclusive later of impact ejecta as was used to prove the end-cretaceous eruptions. It’s possible, but there’s no strong evidence for it yet.
Not really, the Great Dieying was so bad that almost all life died, oceans acidify and the ozone layer almost disappeared. Plus we are actively trying to stop it.
Impossible to say right now. We don't see an increase in global average temperature nearly this rapid anywhere in the geologic record, but we also don't know how long this one is going to last.
04:00 That is hysterical. “Evaporite” is a term my 7 year old would come up with while chattering away about a topic where he has actually memorized only half of the factual information he wants to convey that he knows.
I have an idea of permian survival horror game. Main rule in this game - if you kill some certain predators or creatures, it will f*ck up your evolution and genes of player character. You can cook clams or trilobites or some eurypterid scorpions, BUT if it's creature, which is not evolutionary dead end - your character transforming into a mindless monster faster. And, as it goes, you can't return to your present time. But, if you become a monster, why you still in this time and not erased? How do you manage to get there in a first place after time-alteration? That's main question and secret of the game.
What do you think of the theory that a massive meteor - about 3 to 5 times the size of the one that wiped out the dinosaurs - was responsible for triggering the volcanic activity in Siberia at the end of the Permian? I read that the meteor in question was also responsible for separating Australia from Antarctica.
I want Hollywood videos that base the script on events like the great dying. replacing animals with humans, speeding time up by 20000x, but keeping the order and implication of the events. I'd go back to school to watch that!
The asteroid that caused the extinction of the non-avian dinosaurs is another case of a perfect storm of geology causing a mass extinction. Only in the very specific place the asteroid hit was it able to cause a mass extinction. It came down to literal seconds. If the asteroid had hit 10 seconds before or 10 seconds after, the rotation of the Earth would have meant that the asteroid wouldn't have hit that specific spot and while there would have been a local extinction, the rest of the planet would have been mostly unaffected.
Has the "clathrate gun" hypothesis been invalidated for the Permian extinction ? I heard it could be responsible for increasing the global warming during the second part of the extinction event ?
I think the reason The Great Dying was so bad had a lot to do with all the dying.
Wouldn't have been so bad without it for sure.
💀
I think the animals died in the great dying 🤔
It would just have been „The Great“ without all the dying, sounds more like a good time, so I think your theory holds ground.
Genius turn it into the professor now lol

The great dying is a cautinary tale . Of how mass eruptions can occurr and theres sometimes no warning
Does that mean there has always been a hole in the ozone layer, and how big could it have been during the Permian extinction?
No. There is no reason to believe such a hole would have persisted in perpetuity.
No, our atmosphere has changed composition by good percentages over the eons. We have access to gas trapped in rocks etc, but don't have a good way of telling if we had holes over time.

Great work. Aim High
there is nVidia software now that will make it look like you're looking at the camera even when you're reading the script
I want Hollywood videos that base the script on events like the great dying. replacing animals with humans, speeding time up by 20000x, but keeping the order and implication of the events. I'd go back to school to watch that!
You’re actually so cute Ben best of luck with your further studies and career ❤
The asteroid that caused the extinction of the non-avian dinosaurs is another case of a perfect storm of geology causing a mass extinction. Only in the very specific place the asteroid hit was it able to cause a mass extinction. It came down to literal seconds. If the asteroid had hit 10 seconds before or 10 seconds after, the rotation of the Earth would have meant that the asteroid wouldn't have hit that specific spot and while there would have been a local extinction, the rest of the planet would have been mostly unaffected.
the more you know about the past the more prepared you are for the future
Makes me wonder...
If there was another total extinction event on earth... would things ever eventually evolve back into humanity?
the grade I would give you is G, for a great job😁
Great break down
So if a planet has high CO2 or Methane instead of Nitrogen then no Ozone Layer? This would explain the Fermi Paradox easily.
"I've actually been invited myself. I was there watching the Great Dying" that's what I though he was gonna say at the beginning there
How many horses are in this race ?
Has the "clathrate gun" hypothesis been invalidated for the Permian extinction ? I heard it could be responsible for increasing the global warming during the second part of the extinction event ?
