    Mary Anning was an English fossil(化石)collector，dealer and paleontologist(古生物学家).Her fossil-hunting helped change the way people thought about the world.

Mary was born into a poor family in England on May 21, 1799. She lived in the seaside town of Lyme Regis, in Dorset. The family had nine children. Only Mary and her brother Joseph grew up. Mary's father took his children along the beach. They picked up shells and stones to sell to visitors. Mary did not go to school much. Her family was too poor. And schools did not teach children about fossils. Mary could read and write. She taught herself. She learned about rocks and how bodies are made.

In 1811 when Mary and Joseph were fossil hunting, Joseph saw a bone sticking out of the rock. Mary had a hammer to chip away at the rock. Very carefully she uncovered it. She found the first complete fossil of the ichthyosaur(鱼龙).

Since then, Mary became crazy about fossil hunting. She liked to hunt on the beach after a storm. The wind, rain and waves made the rocks crumble. It was easy to spot fossils. Most days Mary went fossil hunting with her dog, Tray.

Rich friends helped Mary by selling fossils for her. They sent her money. Scientists wrote letters and came to see her. One good friend was William Buckland, a professor at Oxford University. Mary also opened a shop to sell fossils, stones and shells. She chatted with visitors.

Mary Anning died in1847. How evolution(进化)works was explained by Charles Darwin not long after Mary died. Her fossils had helped scientists understand how things began.
