Diagnosis

Reference	Diagnosis
A. Cau et al. 2013 (Sauroniops)	Large-bodied basal carcharodontosaurid dinosaur with the following unique combination of features (autapomorphies marked by asterisk): (1) dorsoventrally thickened frontal (with the depth of the body ranging between 28%, along themedial suture, and 38%, at the level of the anteromedial margin of the supratemporal fossa, of bone length); (2) nasal processes of the frontal with a transversely convex dorsal surface and completely separated medially by the posteromedial processes of nasal extended along 40% of the frontal length and reaching the frontal body; (3) thick domelike eminence in the anterolateral corner of the dorsal surface of the frontal at the level of the prefrontalelacrimal articulations; (4) anterolateral margin of the lateral surface of the frontal with a narrow vertical lamina separating the prefrontal facet from an elliptical fossa in the lacrimal facet; (5) prefrontal facet of the frontal trapezoidal, barely visible in ventral view, mostly restricted to the anterodorsal margin of the lateral surface of the bone, and not participating in the orbital fossa; (6) frontal with interdigitate suture for prefrontal restricted to the anteroventral corner of the facet, formed by a low shelf running along the posterolateralmargin of thenasal process and a small finger-like projection; (7) hypertrophied, ‘D-shaped’ lacrimal facet of the frontal bordering thewhole posterolateral exposure of the prefrontal facet and with maximum depth that is four times the depth of the anterior half of the postorbital facet; (8) dorsal surface of the frontal anterior to the anteromedial margin of supratemporal fossa raised and facing anterodorsally, describing with the dorsal dome a posteromediallyeanterolaterally directed saddle-shaped concavity, and confluent with a series of low rounded rugosities placed posteriorly to the nasal facet.
