If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

Diagnosis
ReferenceDiagnosis
J. F. Bonaparte and F. E. Novas 1985Carnosauria of large size, with high, narrow, widely fenestrated skull with prominent rugosities on the nasals. With antorbital fenestra proportionally larger than in Tyrannosauridae and in the remaining Cretaceous and even Jurassic carnosaurs; small
accessory antorbital fenestra located on the anterior border of the antorbital fossa. Interorbital region wider than in other carnosaurs, and with lateral contact external to the
lacrimal and postorbitals, forming a type of orbital overhang. Orbital fenestra very tall, with a low jugal, and with the orbit as mentioned very marked for the postorbital and lacrimal, forming a circumference hardly open ventrally, partly recalling the condition seen in Tyrannosaurus rex. Squamosal projecting nearly backwards, almost horizontally, with its process for the quadratojugal directed ventrally and not as forwards as in Tyrannosauridae, recalling the condition of Ceratosaurus, and to a lesser degree that of Allosaurus. Quadrate notably longer than in Tyrannosauridae, comparable to Ceratosaurus. Lower temporal fenestra very wide in both directions, notably larger than in Tyrannosauridae, recalling that seen in Ceratosaurus. Upper temporal fenestrae shorter axially. Extended horizontal ramus of the maxilla, provided with thick teeth, very laterally compressed. Braincase comparable to that of Piatnitzkysaurus in the conspicuous aliform processes of the laterosphenoids, and in the marked transverse constriction of the basisphenoids. (Translated by M. Carrano.)
