Mary Anning was a British fossil collector, dealer and palaeontologist who became known around the world for important finds she made in the Jurassic marine fossil beds at Lyme Regis where she lived. Her work contributed to fundamental changes in scientific thinking about prehistoric life and the history of the earth. Her discoveries included the first ichthyosaur skeleton to be correctly identified, found when she was just twelve years old; the first two plesiosaur skeletons ever found; the first pterosaur skeleton located outside Germany; and important fish fossils. Her observations were critical to the discovery that coprolites were fossilised faeces. Geologist Henry De la Beche's Duria Antiquior, the first widely circulated pictorial representation of a scene from prehistoric life derived from fossil reconstructions, was based largely on fossils Anning had found. Her gender and social class prevented her from fully participating in the scientific community of 19th-century Britain, prevented her from joining the Geological Society of London, and prevented her from getting full credit for her work during her lifetime. After her death her unusual life story attracted increasing interest. In 2010 the Royal Society included Anning in a list of the ten British women who have most influenced the history of science.
