In this landmark documentary David Attenborough brings to life, in unprecedented detail, the last days of the dinosaurs.
Palaeontologist Robert DePalma makes an incredible discovery in a prehistoric graveyard – fossilized creatures, astonishingly well preserved, that could help change our understanding of the last days of the dinosaurs. He finds the site records evidence of the final day, when an asteroid bigger than Mount Everest devastated our planet and caused the extinction of the dinosaurs. Based on brand new evidence, witness the catastrophic events of that day play out minute by minute.
