English: Medial surface of the skull of Lokiceratops rangiformis (EMK 0012). (A) Photomosaic of internal surfaces of the facial region of EMK 0012 in medial view. Most elements are from the right side of the skull except for the lacrimal, palpebral, jugal, quadratojugal, and distal wing of the squamosal which are reversed from the left side for clarity. (B) Interpretative line drawings in lateral view. Dark gray indicates broken edges, stipples indicate midsagittal sutures of elements along the midline. Lighter gray indicates the outline of the skull interpreted from the preserved material. Orange denotes putty infilling cracks. Note that while the nasal appears to have a peaked ornament dorsally, there is no evidence of a narial ornament in this specimen. This is an artifact of breakage.
