RIPPLE MARKS
A good example of ripple-marked sandstone
370 million years old
(Late Devonian period)
Hangman Sandstone Formation
Cliffs west of Minehead, Somerset
This sandstone was laid down in shallow water and shows unmistakable ripple marks that were formed along a long-lost coastline some 370 million years ago, when Britain was part of the supercontinent known as Pangea.
At that time Britain was situated just south of the equator and a continental collision had created a vast mountain range over what is now Cornwall and Devon. Evidence of this collision can be seen today in the spectacular folding of the rocks along this part of the coast.
Please note that some photographs are taken using oblique lighting to make the ripples easier to see.
