The discovery was made in Argentina, and in a forthcoming documentary, naturalist Sir David Attenborough will tell the story of what led experts to make the amazing find.
Compared to a large Diplodocus, the titanosaur was a whopping 36ft (11 metres) longer. To put that into perspective, the prehistoric creature would have been the length of four double-decker buses. This graphic shows how Sir Attenborough would have looked stood next to the beast
The vegetarian titanosaur is thought to have been the biggest animal ever to have walked the Earth, weighing 70 metric tons - the equivalent of 14 African elephants.
Compared to a large Diplodocus – one of the most easily recognisable dinosaurs - the titanosaur was a whopping 36ft (11 metres) longer.
To put that into perspective, the prehistoric creature would have been the length of four double-decker buses.
Using state of the art graphics, the programme reveals what scientists think the internal structure of a dinosaur looked like and how it worked.
The documentary finishes with the unveiling of a massive skeleton built by a Canadian and Argentinian team of model makers, which represents the newly-discovered titanosaur.
