Lucy is, quite possibly, the most well-known fossil hominid. Discovered by Donald Johanson and Tom Gray in 1974 at Hadar, Ethiopia, Lucy is dated at 3. 2 million years old. This specimen, a 40% complete skeleton of an adult female, gave sufficient evidence that A. afarensis was a bipedal species that walked upright. Lucy, scientifically known as AL 288-1, was named after the Beatles song Lucy in the Sky with Diamonds.nnSpecifications:nn1:1 scalenPolyurethane resin castn2-part skull (separate cranium & jaw)nnSkull Length 16.6 cm (6.5 in.)nSkull Width 13.1 cm (5.2 in.)nSkull Height 14.5 cm (5.7 in.)nnStand Comes Complete With A Custom Cradle Designed Specifically For This SkullnnOrigin: EthiopiannProduct of Bone Clones
