Permian Extinction


The disaster, known as the Permian-Triassic extinction event and referred to by Nasa as "The Great Dying", occurred when the Earth's continents were mashed-up into one landmass, known as Pangaea. It's thought to have been triggered by a combination of climate change, acid rain, ocean acidification and anoxia.

I am impressed.  This is the first time that I've seen plate tectonics mentioned with extinction.  This what I've always pushed.  All sorts of atmospheric change and the rise of the big flightless birds (dinosaurs).  Are they ever going to mention what happens when the continents break up again?  Are they always going to go with the meteor theory?  I can only wait, and fish off my dock.  :)
