There's also a fungal spike: everything died and went moldy. And when the forests had grown back, there are wild swings in their composition for a long time; it looks like the hydrological cycle was completely out of whack.

If the atmosphere got that hot, and caused fires, it would probably generate a lot of steam from bodies of water, would it not?
