Mary Anning (21 May 1799 – 9 March 1847) was an English fossil collector, dealer, and paleontologist who became known around the world for important finds she made in Jurassic marine fossil beds in the cliffs along the English Channel at Lyme Regis in the county of Dorset in Southwest England.[2] Her findings Mary Anning searched for fossils in the area's Blue Lias cliffs, particularly during the winter months when landslides exposed new fossils that had to be collected quickly before they were lost to the sea. She nearly died in 1833 during a landslide that killed her dog, Tray. Her discoveries included the first ichthyosaur skeleton correctly identified; the first two more complete plesiosaur skeletons found; the first pterosaur skeleton located outside Germany; and important fish fossilscontributed to important changes in scientific thinking about prehistoric life and the history of the Earth.
