In 1812, at Lyme Regis on the Dorset coast, an extraordinary child named Mary Anning—aged eleven, twelve, or thirteen, depending on whose account you read—found a strange fossilized sea monster, seventeen feet long and now known as the ichthyosaurus, embedded in the steep and dangerous cliffs along the English Channel. It was the start of a remarkable career. Anning would spend the next thirty-five years gathering fossils, which she sold to visitors. (She is commonly held to be the source for the famous tongue twister “She sells seashells on the seashore.”)
