Catastrophe

In episode two, Asteroid Strike, dinosaurs rose up as rulers of Earth around 230 million years ago, eventually dominating all other species and relegating mammals to the shadows. But 65 million years ago the planet was rocked by a massive event when, seemingly out of nowhere, the mighty dinosaurs were wiped off the face of Earth.

This three-part series, presented by Tony Robinson, investigates the history of natural disasters, from the planet's beginnings to the present, putting a new perspective on our existence and suggesting that we are the product of catastrophe. Episode one looks at the greatest climate disaster ever to have hit Earth. 650 million years ago, a cataclysmic ice age sealed the entire planet beneath ice and snow, almost destroying life and turning the world into one huge snowball.
