Sir David Attenborough has come face-to-face with a huge 'fish-lizard' dinosaur that could be the first of its kind discovered.

The BBC stalwart was filming for a new show about a Ichthyosaur fossil discovered in Lyme Regis, Dorset earlier this year.

It is believed the fossil may belong to a species that has never been seen before, and, potentially the biggest ever found in the UK.

British fossil hunter Chris Moore discovered it earlier this year, but it was removed from the rock just yesterday.

Mr Moore and Sir David worked alongside a BBC crew to remove the ancient remains which date back up to 200 million years.

The pieces of the Ichthyosaur (which literally translates to 'fish-lizards')were loaded onto a pontoon and taken ashore by two boats.

Mr Moore added: "It's very exciting."

The natural history show will focus on a remarkable chance discovery that could reveal secrets that have lain hidden for 200 million years.

The one-hour special - expected to air in 2018 - will show the fossil being excavated, prepared and scanned before a replica of its skeleton is constructed.

Then its physical attributes will be scientifically tested revealing the secrets of these animals and the Jurassic world in which they lived.

It follows from Attenborough and the Giant Dinosaur, which pulled in eight million viewers earlier this year with a story about a giant dinosaur which had been unearthed in Patagonia.

Ichthyosaurs were predatory marine reptiles that evolved from an as yet unidentified land reptile that moved back into the water.

They appeared in the world's oceans in the Triassic period and died out around 25 million years before dinosaurs were wiped out.

The huge animals - some species of which had a cruising speed of 36kmph - remained at the top of the food chain until they were replaced by the plesiosaurs.
