Lucy is one of the best-known fossilized hominid skeletons. With about 40 % of it preserved, it was discovered in Ethiopia in 1974. The Australopithecus lady received her name from the Beatles tune “Lucy in the Sky with Diamonds.” It is believed that she lived 3.2 million years ago in Ethiopia’s Afar triangle. Lucy stood a mere 105 centimeters tall and weighed approx. 27 kilograms.
