(A, B) Holotype postorbital region of skull (QMF 6710) and (C, D) referred snout (QMF 6676) in (A) dorsal; (B, C) right lateral; (D) and left lateral views. Numbers indicate character-states scored in the data matrix and the arrows indicate anterior direction. Abbreviations: apsq, anterior process of the squamosal; dt, dentary; fr, frontal; la, lacrimal; mfo, median fossa; mpsq, medial process of the squamosal; mx, maxilla; po, postorbital; pofr, postfrontal; ppsq, posterior process of the squamosal; qj, quadratojugal; sa, surangular; stf, supratemporal fenestra; stfo, supratemporal fossa; vpsq, ventral process of the squamosal. Scale bars equal 2 mm. Character state scores=

• 8-1: Supratemporal fossa immediately medial or anterior to the supratemporal fenestra on the dorsal surface of the temporal region of the skull.
• 13-0: Antorbital fenestra absent.
• 116-1: The parietals enter strongly between both frontals, forming an acute-angled suture.
• 139-0: The transition between the anterior and ventral processes of the squamosal is sharp, with the posterodorsal border of the infratemporal fenestra having a square outline.
• 151-0: The quadratojugal is L-shaped or strip-like.
• 162-1: A pineal fossa is present on the medial line of the dorsal surface of the parietals.
• 163-0: The pineal fossa is restricted to the parietals.
• 164-0: The pineal foramen is large in dorsal view.
• 165-0: The pineal foramen is positioned in the anterior part of the parietals yet completely enclosed by the bones.
• 166-1: The parietals have a distinct transverse emargination near the posterior margin of the bone.
