These remains (Lucy - AL288) were found in the Hadar region of Ethiopia.

Lucy is one of the most important of all fossil hominid finds, with 40 percent of the skeleton recovered; [Boyd & Silk 1997] , pp 342-359.

The species Australopithecus afarensis was named in 1978 to include "Lucy" and the hominid footprints discovered in Laetoli by Mary Leakey and her team.

• What did "Lucy" look like in life?

A. afarensis is widely believed to be ancestral to the other known hominids.

The Ethiopian specimens have been dated to between 2.9 and 3.5 million years.

The footprints have been dated to between 3.6 and 3.75 million years.

Bringing both these sets of specimens into a single species was controversial at the time, and is still questioned by some specialists.
