Femur Heads

Caption

Two femora, on the left is a large, presumably male specimen and on the right is Lucy. The difference between these two gives the impression of a large size differences between the sexes. However, inclusion of the many intermediately sizes specimens from this species indicates that the size variation is similar to moderately dimorphic humans.
