Welsh storms expose Stone Age landscape
Winter storms which battered the coast of Wales have exposed previously hidden traces of the area's Stone Age landscape.
A four mile stretch of coastline near Tywyn on the west coast of Wales was so altered by the sea that it was pushed back 50 feet (15 metres).
The new coastline has revealed the existence of ancients forests, with the remains of trees dating back 6,000 years.
