The block containing the humerus and
eventually the hominin skull MH1.  The
skull lies in the upper part of the block,
just above the proximal end of the
humerus.  On the 6th of March 2009 I
had no idea the skull lay just a few
millimeters away! See the image to the
left of this thumbnail to see what
emerged! Photo by Lee R. Berger.
