Cheddar Gorge in Somerset’s Mendip Hills is one of Britain’s most beautiful natural wonders, with its sweeping limestone cliffs, and striking natural rock chambers.

But new evidence suggests the picturesque site had a deeply sinister past.

Paleontologists have discovered that around 15,000 years ago, British cave dwellers filleted and ate their dead relatives before inscribing markings on their bones in grisly prehistoric rituals.

It is the first time that such practices have been found in the Paleolithic, or Old Stone Age - which dates from 2.6 million years ago to around 12,000BC - anywhere in the world.
