Attenborough is currently working on the new docu-film all about the UK’s fascinating prehistoric era.

The programme - a 60-minute film for BBC One and iPlayer, with a working title of 'Attenborough and the Giant Sea Monster' -sees the 96-year-old bring to light long-lost secrets of the ancient world.

Filmed on location across the UK, Attenborough was joined by a team of fossil experts to unlock the mysteries surrounding the amazing discovery.

The find in question was the skull of a giant Pliosaur, which is regarded as 'one of the most ferocious Jurassic predators ever known', the BBC reports.

"This enormous prehistoric marine reptile ruled the seas at the same time dinosaurs reigned on land, 150 million years ago," the doc's premise explains.

That's some pretty old bones.

Palaeontologists believe this Pliosaur to be a 'completely new species', as they are currently undergoing work in a 'secret location', to excavate the humungous skulls.

In hopes to 'uncover the secrets lying deep within', Attenborough's miraculous discovery is definitely another accolade to add to his already jam-packed portfolio of iconic moments.

Speaking of the fantastic find, Attenborough explained: "Pliosaurs were the biggest and most formidable hunters in the Jurassic seas – the marine equivalent, you might say, of T-rex.

"The skull of this one is, by itself, over two metres long and armed with massive fangs."

Imagine that swimming next to you off the coast of Dorset.

Attenborough continued: "Skulls, which can tell us most about an animal, are easily smashed before fossilisation.

"But this one is virtually undamaged and promises to reveal all kinds of new details about these terrifying hunters that preyed on Lyme Regis’s better-known ichthyosaurs."

The documentary, which is filmed on location all across the UK, will 'combine ground-breaking science with gripping storytelling and state-of-the-art CGI to tell the tale of this most phenomenal predator of the Jurassic world'.

Executive Producer, of the documentary, Mike Gunton, said: "It's wonderful to be back on location with David - his eyes absolutely lit up when we told him about this amazing find – he couldn’t wait to join the 'dig' and get a first look at the fossil bones for himself."

Jack Bootle, Head of Commissioning, Specialist Factual, added: "David has filmed some of the world’s very best fossil animals, so the fact he’s so interested in this skull makes me unbelievably excited.

"This film promises to be a thrilling trip through time to a moment when monsters ruled the seas around Britain. I can’t wait for viewers to experience it."

Neither can we.

Attenborough and the Giant Sea Monster (w/t) will soon be available to watch on BBC One and BBC iPlayer.
