I’m probably going to judge you if you say Holocene, without an interesting non-trivial reason.
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!
Nice try glowy!
whichever the next one is that’ll be my favorite
The oxygenation of the ocean. Never knew that was a mass extinction! So much interesting stuff came from that!
