SIR David Attenborough will unveil remains of the largest dinosaur to ever walk the planet on a new BBC program.

The famous broadcaster and naturalist will reveal a 37m long skeleton model of the 70 tonne Titanosaur on Attenborough and the Giant Dinosaur, to be aired on Sunday January 24 on BBC One.

Titanosaurs were a group of sauropods, which were plant-eating dinosaurs with four legs and long necks. From nose to tail, the dinosaur is nearly the length of four London double-decker buses lined up, making it the biggest animal the world has ever seen.

Remains of the species of titanosaur were discovered by a Patagonian shepherd in 2014 in the Argentinian desert. He spotted what turned out to be the tip of a 2.4m long femur thigh bone — the largest ever found.

Palaeontologists excavated the area and uncovered more than 220 fossilised bones belonging to seven different dinosaurs. One of those was the new species of titanosaur — a herbivore that is yet to be given its own scientific name.

Excavate and chill.

Lead scientist on the excavation Dr. Diego Pol said the site was unlike anything he’d ever seen before.

“It was like a palaeontological crime scene, a unique thing that you don’t find anywhere else in the world with the potential of discovering all kinds of new facts about titanosaurs,” he said.

“According to our estimates this animal weighed 70 tonnes. A comparison of the back bones shows that this animal was 10 per cent larger than Argentinosaurus, the previous record holder. So we have discovered the largest dinosaur ever known.”

Attenborough and the Giant Dinosaur was subsequently filmed over the next two years and details scientists’ forensic investigations in their effort to prove the enormous animal is the largest ever discovered.

The show has used CGI technology to recreate what the dinosaur’s internal structure was like and how it worked. The titanosaur allegedly had a heart that weighed the same as three people.

It is thought to be 100 million years old.
