What Mary Anning found in the cliffs in 1811, when she was 13, was the first complete fossil of an ichthyosaurus, a marine dinosaur. She hunted and sold fossils to save her family from poverty after her father died when she was 11 years old. Despite social disapproval of her unfeminine occupation, Mary persisted and became a leading fossilist who made valuable contributions to science.
