The antorbital cavity in front of the eye consisted of two fenestrae (openings); a large antorbital fenestra at the back, and a small maxillary fenestra at the front. Nemegtomaia was distinct from other oviraptorids in that the frontal bone on the midline of the skull was about 25% the length of the parietal bone from front to back.

Nemegtomaia was distinct from other oviraptorids by having its frontal bone, running along the midline of the skull, about 25% as long as the parietal bone from front to back.
