Another recommended read (which I’m in the middle of right now) is The Ends of the World: Volcanic Apocalypses, Lethal Oceans, and Our Quest to Understand Earth's Past Mass Extinctions by Peter Brannen.

Coincidentally I’ve just reached the Permian mass extinction event, where the author discusses how the ammonites clocked out in a later mass extinction. A related species, Nautiluses, have survived till today and are now at risk of extinction because humans prize their beautiful shells.

We humans are atoms in the scope of geological time, but time will tell if we prove to be atoms of Uranium in Little Boy...
