David Attenborough brings to life, in unprecedented detail, the last days of the dinosaurs. Palaeontologist Robert DePalma has made an incredible discovery in a prehistoric graveyard: fossilised creatures, astonishingly well preserved, that could help change our understanding of the last days of the dinosaurs.

Based on brand new evidence, witness the catastrophic events of that day play out minute by minute.
