Lucy was discovered in Hadar, Ethiopia

Lucy was discovered in Hadar, Ethiopia on November 24, 1974 when Johanson, coaxed away from his paperwork by graduate student Tom Gray for a spur-of-the-moment survey, caught the glint of a white fossilized bone out of the corner of his eye and recognized it as hominin. Forty percent of the skeleton was eventually recovered and was later described as the first known member of Australopithecus afarensis. Johanson was astonished to find so much of her skeleton all at once. Pamela Alderman, a member of the expedition, suggested she be named "Lucy" after the Beatles' song "Lucy in the Sky with Diamonds," which was played repeatedly during the night of the discovery.
