No it's not Loch Ness.
The fossilised skull of a colossal "sea monster" has been unearthed along the UK's Jurassic Coast.
The ferocious predator, which is called a pliosaur, terrorised the oceans 150 million years ago.
The skull is 2.4m long, and experts say it could belong to one of the largest pliosaurs ever found: measuring up 16m in length.
