A skull belonging to one of the largest "sea monsters" ever unearthed is being unveiled to the public.

The beast, which is called a pliosaur, has been described as the most fearsome predator the Earth has seen.

The fossil was found in Dorset, but it has taken 18 months to remove the skull from its rocky casing, revealing the monster in remarkable detail.

Richard Edmonds, Dorset County Council's earth science manager for the Jurassic Coast, reveals how the creature would have devoured anything and everything in its path.
