Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| K. Post et al. 2017 | With a bizygomatic width greater than 14 cm, the robust cranium of Scaldiporia vandokkumi differs from other inioids in the autapomorphic presence of large, dorsoventrally thick (23 mm) premaxillary eminences reaching the level of the antorbital notch, in both the posteromedial and posterolateral sulci being consequently not dorsally visible, and in the presence of occipital tuberosities on the posterior surface of the nuchal crest. It further differs from other inioids in the following unique combination of characters: dorsomedially sloping dorsal surface of the premaxilla at the rostrum base; maxilla narrower than premaxilla at rostrum base; progressive (versus abrupt) elevation of the dorsal surface of the maxilla from rostrum base towards antorbital region; presphenoid not present between premaxillae anterior to premaxillary eminences; lateral edge of bony nares formed by maxilla posteriorly; posterior apices of premaxillae not diverging; posterior edge of the premaxilla distant from the nasal; right premaxilla roughly reaching the anteroposterior level of the posterior margin of the bony nares; poorly elevated vertex; vertex distinctly shifted to the left side of the asymmetric cranium; anteroposteriorly elongated nasals; nasals posteriorly pointed; deep internasal fossa; supraoccipital barely anteriorly wedged between frontals and maxillae, with nuchal crest nearly straight; supraoccipital shield with distinct trapezoid outline in posterior view, due to posteromedial extension of the temporal fossa; and presence of a fossa for the postorbital lobe of the pterygoid sinus. |
