I highly recommend The Sixth Extinction: An Unnatural History by Elizabeth Kolbert if you like this topic. A great read that tells you about the extinction-level event that we are currently part of and, is most likely, caused by us (i.e., humans).

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...
