Brand new film documents minute by minute what happened when the asteroid hit earth - with the fall of the dinosaurs brought to life in unprecedented detail.

We all think we know what happened to the dinosaurs: 66 million years ago, at the end of the Late Cretaceous, an asteroid hit the planet and wiped them out.

But that’s far from the whole story. While the asteroid impact itself is well documented, no direct evidence has ever been found that confirms how it killed the dinosaurs.

Now, a new dig site promises to change that. Hidden in the low hills of North Dakota lies a secret, prehistoric graveyard known as Tanis. There, fossilised creatures dating from the very end of the Late Cretaceous lie buried in a mysterious crumbly layer of rock. And they are preserved in such detail that they could help give us a clearer picture of that time than ever before.

David Attenborough says: “Dinosaurs were among nature's most extraordinary creatures, dominating the planet for over 150 million years before they became extinct.

“Tanis could be a place where the remains can give us an unprecedented window into the lives of the very last dinosaurs, and a minute-by-minute picture of what happened when the asteroid hit.”

Jack Bootle Head of Commissioning, Science and Natural History, says: “BBC Studios Science Unit has brilliantly combined cutting-edge CGI with the very latest science to depict, in meticulous detail, what happened on the day of the asteroid strike. I’ve longed to know exactly how the dinosaurs died ever since I was a little boy. Now, finally, I can see it.”

Attenborough looks at some of the fossil finds with leading experts and follows the dig team as they carry out cutting-edge visualisation and scanning techniques to reveal fossilised secrets invisible to the naked eye. Brand new VFX production techniques are used to immerse David in the Late Cretaceous and bring the creatures which lived at Tanis to life.
