CNN.com has this cool article about some new discoveries about the early paleocene, the time just after the dinosaurs. Turns out at least some parts of the planet recovered a lot more quickly than was once thought.

I've always thought these "edge" periods to be at least, if not more, interesting than, say, the ice age or the age of dinosaurs. I really think the Discovery channel should do a whole series of shows on, say, the cambrian explosion, when multicellular life sort of suddenly "appears" on the world's stage.
