Colossal sea monster unearthed in UK

The skull of a colossal sea monster has been extracted from the cliffs of the Jurassic Coast in Dorset, UK.

It belongs to a pliosaur, a ferocious marine reptile that terrorised the oceans about 150 million years ago.

The 2m-long fossil is one of the most complete specimens of its type ever discovered and is giving new insights into this ancient predator.

The skull will be featured in a special David Attenborough programme on BBC One on New Year's Day.
