fragment of mesh missing after obj export and import to rhino

Hi, after I exported my figure from daz, as an .obj using poser presets, and importing it into rhino, everything looks fine except there is a part of the mesh forming the back of my characters head which is missing. Whaaat's the deal?

Did you have an extra body part attached to the figure?
