What Happened in the 10 Million Years After the Asteroid (in 13 minutes)

The asteroid hit 66 million years ago. That part everyone knows. But what happened in the next hours, years and the first 10 million years? A wave that came too early, an impact winter that turned out to be different from what models predicted, sharks that never recovered, mammals in China that grew big before they figured out how to eat — and a "sequel" 10 million years later, with no asteroid at all. Every claim in this video comes from a peer-reviewed paper. All sources are listed below. Where science is still debating, we say so.
