The narrow premaxillary foramen, posterior to the antorbital notch, is depressed compared to the slightly concave premaxillary sac fossa. The elevated lateral margin of the fossa overhangs the maxilla along its posterior half. The lateral margins of the ascending processes of the premaxillae are parallel until the elevated vertex. The vertical anterior surface of each ascending process is hollowed out by a deep elliptical fossa, extending medially on the anterolateral surface of the nasal. The right fossa is wider than the left. In relation to the morphology of the air sacs connected to the nasal passages and the surrounding bony configuration in Recent ziphiids and other odontocetes (

a homologous air sac was located in this elliptical fossa. A pair of smaller fossae is present ventromedially at the naso-mesethmoid suture (best seen in SAM PQ 2086), probably related to the foramina of the terminal nerve. The mesethmoid is weakly or not keeled under the nasals.
