I've never known why Pangaea was stable for billions of years, then broke up in fire and death 200M years ago. Anybody have a reference?

Pangaea "only" existed for around 135 million years.

+1. Wikipedia has good info: https://en.m.wikipedia.org/wiki/Supercontinent_cycle

Take anything past 1 billion years ago as highly provisional.

I also really like this site: https://dinosaurpictures.org/ancient-earth#0

One reason why no one really talks about anything before Pangaea is that there wasn’t interesting land life much before that, so the previous supercontinents don’t “matter” much in terms of evolution.

Personally I find the devonian and carboniferous much more interesting than the mesozoic. And the ediacaran if counting marine life. There's plenty of people "talking about it", it's just not pushed like dinosaurs. A couple of good yt channels:

- Royal Tyrrel Museum of Palaeontology

- Virtual Seminars in Precambrian Geology
