A gully at Hadar, 24 November 1974
In 1974, Donald Johanson and the graduate student Tom Gray were mapping and searching for fossils at Hadar, Ethiopia, when Johanson chose an alternate route back to their Land Rover through a gully.
He spotted a right proximal ulna and recognized it as hominin. Skull, femur, rib, pelvis and jaw fragments lay nearby — the mark of an associated skeleton rather than one stray bone.
Forty percent
The team marked the locality and began recovery. Two weeks of excavation, screening and sorting produced 47 bones representing about 40 percent of a single skeleton.
The individual dates to about 3.2 million years ago and stood roughly 3.5 feet tall at an estimated 60–65 pounds. Her identification as female rests principally on her small size within a strongly sexually dimorphic fossil sample.
The name arrived that night
During the celebration that evening the Beatles' “Lucy in the Sky with Diamonds” played repeatedly, and the fossil acquired its nickname. Nobody later remembered who proposed it.
The scientific name came four years later: Johanson, Tim White and Yves Coppens formally named Australopithecus afarensis in 1978.

What the sources leave uncertain
- The date, place and discoverers are well documented.
- No team member could later remember exactly who first suggested the nickname Lucy.
- Lucy was only retrospectively classified as Australopithecus afarensis after Johanson, White and Coppens formally named the species in 1978.
- Lucy's identification as female rests principally on her small size within a strongly sexually dimorphic fossil sample.
