David Attenborough presents this landmark documentary which brings to life, in unprecedented detail, the last days of the dinosaurs. Palaeontologist Robert DePalma makes an incredible discovery in a prehistoric graveyard known as Tanis in North Dakota – fossilised creatures, astonishingly well preserved, that could help change our understanding about the final days of the dinosaurs. Meanwhile, state-of-the-art visual effects transport David Attenborough back in time to the Late Cretaceous to find out about the creatures which lived at Tanis. Finally, based on new evidence, witness the events minute-by-minute on the day an asteroid devastated our planet wiped out the dinosaur.
