In 1974, Lucy was found, the fossil bones of an Australopithecus afarensis.

Lucy takes her name from Lucy in the Sky with Diamonds, and she is part of the collection of the National Museum of Ethiopia. The fossil was found at Hadar, and Donald Johanson, Tom Gray, Maurice Taieb and Yves Coppens are credited with the discovery. She lived more than three million years ago.
