Not a full on extinction event, but the late bronze age collapse has always fascinated me. So much do that it led me to pursue archaeology in college.
So many theories, everyone has their favourite, but yeah, what ultimately caused every near eastern civilisation as well as the Mycenaean Greeks to just all collapse and disappear over a relatively short 200 years or so (archaeologically speaking a blink-of-an-eye)
The Azolla Event. https://en.wikipedia.org/wiki/Azolla_event. I mean it is cool and the major climate shift it helped create certainly caused some extinctions. But plants can change the world, never forget!
Very cool!
It reminds me of my fav, The Oxygen Catastrophy, where basically a plant did something new and caused the earth to freeze. In this case, by converting methane to carbon dioxide, a much weaker greenhouse gas.
Ooh, since this is a safe space for dorks, I would like to be pedantic myself. Thank you for the opportunity. The oxygen catastrophe was caused by cyanobacteria-like organisms, which are photosynthetic, but are not plants. But itβs true, all bio-mass matters!
Yeah I knew they weren't plants but it made the analogy easier to pretend they were π
They have plant-ey vibes
They were all like "let's get the Calvin cycle up in this house, lets light it up!" And so they did, and the atmosphere caught fire
That's interesting. What makes cyanobacteria distinct from plants?
The first thing that comes to mind is that bacteria are prokaryotes, while plants are eukaryotes. They have internal membranes, called thylakoids, in which they do photosynthesis, but chloroplasts in plants are fully-developed organelles with their own DNA. If I recall correctly, the current thinking is that chloroplasts developed from endosymbiotic cyanobacteria.
whichever the next one is that'll be my favorite
I think we're in the start of it now, let's gooooo
The oxygenation of the ocean. Never knew that was a mass extinction! So much interesting stuff came from that!
That's my fav too.
"The Oxygen Catastrophy" is just such a cool name.
Fuckin metal
This is the one where the ocean turned purple wasnt it?
Sounds right. I saw a documentary about it a fee months ago.
I wouldn't call any extinction event a favorite, because it is a loss. An interesting one that is less known than the Dodo is that the wake island rail bird was hunted to extinction by starving Japanese soldiers in WWII. The Americans blockaded the island, trapping the Japanese there, and they ate all the birds in just a couple years time.
I think it's an interesting extinction because it's an unintended casualty of war.
I was asking for extinction events, aka mass extinctions.
But this is still very interesting! Thanks for sharing it with me
Discussion: you can have an "extinction event" in any ecosystem-- not just biological ones.
For example, the abandonment of steam locomotives in the mid-20th-century, or the Home Computer crash of the 1980s.
Similar to a biological mass extinction, you have:
I like it!
I kind of feel like "locomotive" itself is a niche so this is more like a collapse of a niche rather than a mass extinction, but I love the analogies
When the hyper intelligent dinosaurs lost control of their nuclear power plants and their society collapsed.
Just a pet theory of mine.
They made it. They're in the delta quadrant.
wheres the star wars but with dinosaurs series?
The Holocene.
I'm judging you, not because you chose the Holocene, but for how easy it was to get people without interesting opinions to identify themselves π
I was just teasing. But you received some really interesting replies. Good post!
The Holocene.

Nice try glowy!
The ongoing one, cause I get to take part in it!
I'm judging you, as I said I would
Hell yeah, this one is ours!
The one with the internet, whatever that's called.
Yep, that one's the Holocene.
Zombie apocalypse. Anyone left over is either immune from the cause or smart enough to avoid it.
Just me but I like the idea of a peaceful world.
Devonian. I was extincting before it was cool.
Late-Permian extinction. Not very imaginative, but I find it cool that there are so many hypotheses even about the largest mass extinction ever.
The current one playing out. Because I 'm tired.
That's the Holocene, and I'm judging you.
Nice try, FBI!
Im not mad about this current one.
