Along the coast of England can be found a range of stunning white cliffs that owe their striking white colour to a composition of chalk, interrupted only by streaks of black flint. The chalk consists of the remains of shells from millions of microscopic creatures which lived on the seabed over 70 million years ago. So the next time you walk or cycle one of the cliffs’ paths, you are truly treading on fossils!
