She sells seashells

You are supposed to be able to say “She sells seashells by the seashore” three times very quickly. But there is a story behind this alliterative tongue-twister. It memorializes a little girl named Mary Anning who was born in 1799 in Dorset. She was taught by her dad how to search for shells and fossils at the foot of the Dorset cliffs during low tide. When her dad passed away Mary’s sea shell stand on the beach helped to sustain the family. At the age of twelve she dug up a two hundred million year old fossil of a dinosaur, the first such find in England. This was at a time when most people believed the earth was six thousand years old !!

While on the subject of tongue-twisters, try this one if you dare:
