Here’s a good rundown of earth history. I’ve been finding myself reading into earlier geologic time periods out of sheer fascination.
This is amazing.
There’s a really great documentary, “a history of planet earth” that walks you through it and it’s fascinating. The Cambrian explosion was neat as shit.
I love the way that the Quaternary period has both humans and sabre tooth cats as a hazard. it makes you realize how much can change over geologic timescales.
