Is this the material that Johanson's team found? I have a PBS video
documentary on Johanson's discovery of a complete "female"
A. afarensis morphotype ulna.
Johanson also showed a "male" morphotype ulna that was clearly
nearly twice the size of the "female" morphotype (although
the "male" ulna was fragmentary; the proximal articular surfaces were
in perfect condition, though).
Is the Omo Basin in Ethiopia?
