>wiping out the dinosaurs and three-quarters of all other life. The interesting thing about mass extinctions is that they're worse than you imagine from the way scientists commonly phrase it. 75% of species on earth were driven extinct, but that doesn't mean it killed 75% of the trees and bushes and animals and fish. It means it killed every single member of 75% of those species. If you counted the gross number of macroscopic living things before and after, the real portion of them killed was much higher than 75%.
