English: Elements of the parietosquamosal frill of Lokiceratops rangiformis (EMK 0012) in dorsal view. Photographs of the parietal, squamosal, and parts of the postorbital and frontal of EMK 0012 in dorsal view. Note that all elements were photographed on a flat surface and contain parallax and plastic deformation as found in the quarry. This is especially true of the midline parietal bar, in which the right side is curled ventrally. The left side of the frill is complete, and each piece clicks into place with the rest of the frill as does the distal right side of the frill. Osteological abbreviations: dc, dorsotemporal channel; ds, dorsocranial sinus; DTF, dorsotemporal fenestra; ep1–ep7, epiparietals 1–7; es1–es3, episquamosals 1–3; ff, frontal fontanelle; lpb, lateral parietal bar; LTF, laterotemporal fenestra; mpb, midline parietal bar; mpe, midline parietal embayment; ON, otic notch; pfe, parietal fenestra; SQ, squamosal; ssp, squamosal step. Photos by Marcus Donivan. Scale bar equals 20 cm.
