BBC Earth (DStv channel 184) with will be celebrating the 90th birthday of Sir David Attenborough with a series of programmes, including Attenborough and the Giant Dinosaur, this weekend.

Attenborough and the Giant Dinosaur will be screened on Sunday, May 8 at 4 pm. In 2014, news broke that a giant fossil bone had been discovered in the Argentine desert. It was thought to belong to the biggest dinosaur to walk the Earth, and the story piqued the interest of people around the world, including legendary broadcaster Sir David Attenborough.

This documentary follows Sir David as he goes out to Patagonia to meet the scientists who made the discovery. The film follows their work over a two-year period as they work to piece together a 37-metre long skeleton from over 220 bones.

With the help of state of the art graphics, the film reveals how the life of such a giant was possible and questions how and why the species died.
