I loved the description of the K-T Boundary as a "great ecological cast change"

'We can’t help but draw our own history to this specific moment, the dawn of the Age of Mammals, when fuzzy beasts could finally flourish. Dominant dinosaurs suffered a stroke of cosmic bad fortune, and our mammalian kin inherited a planet where they would no longer have to fear death in reptilian jaws. The image is of a great ecological cast change, different players continuing the evolutionary story. It’s a very appealing distortion.'
