There may be a small problem with this idea, in that the sauropod hip may=
 not have allowd this.  If one rotates a sauropod hip so it is standing on=
 two legs, the head of the femur seems to be positioned right below a suture=
 in the hip bones.  This is not a very structurally sound arrangement, IMHO.
