The head reconstructed for the Lucy figure was based on a composite female skull restoration. The reconstruction of a more complete male skull, A.L. 444-2, at left, is a more typical case study.
The sites where the chewing muscles were attached to the skull are very strongly marked in the A.L. 444-2 skull, indicating well-developed muscles. The lower nasal bones are flat and show no indications of a projecting nose. Any reasonable reconstruction of nasal cartilages results in a flat, apelike nose.
Many of the distinctive features of the restored A.L. 444-2 skull are reflected in the final form of the fleshed-out head. The lateral flare of the cheekbones results in a very wide face. The jaws project forward, with a convex area between the nose and mouth.
The head reconstructed for the Lucy figure, based on the composite female skull restoration, proceeded similarly, and looks much like a daintier version of the A.L. 444-2 reconstruction.
