A massive dinosaur, the largest animal to walk the Earth, will be revealed by the famous broadcaster and naturalist Sir David Attenborough in an upcoming BBC show. The 37-metre long animal weighed more than 920 average adults or 14 adult African elephants.

The giant dinosaur species Titanosaur, which has not yet been named, weighed up to 70 tonnes and existed 95 million years ago during the late Mesozoic era, a period when dinosaurs ruled the Earth.

It was discovered two years ago – a shepherd saw the tip of a huge fossil bone sticking out from a rock in La Flecha Farm in the Patagonian province of Chubut, Argentina
