An artist's impression of a 45-ton pliosaur attacking
The fossilised skull of a "sea monster", which may be the largest of its type ever found, has been unearthed on the Dorset coast.
The skull from the ferocious prehistoric predator the pliosaur is 2.4 metres long and could belong to a creature measuring up to 16 metres in length from tip to tail and weighing up to 12 tonnes.
Pliosaurs were a form of plesiosaur, a group of giant aquatic reptiles that terrorised the ocean 150m years ago, around the same time that dinosaurs roamed the Earth.
They had short necks and huge, crocodile-like heads that contained immensely powerful jaws and a set of huge, razor-sharp teeth.
