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
C. R. Scherer and C. Voiculescu-Holvad 2024Teratophoneins can be distinguished from other tyrannosaurines on the basis of the following combination of synapomorphies (those marked with ‘*’ denote characters with states assessed for all included taxa): Ventral margin of maxillary fenestra strongly anterodorsally inclined (C387; Voris et al., 2020), rostrocaudally narrow subcutaneous surface anterior to promaxillary fenestra (C388; Voris et al., 2020), maxilla alveoli count <13 (11 in Teratophoneus and Lythronax [C261; Carr et al., 2011; Loewen et al., 2013]), presence of thick rugose ornamentation on lateral surface of jugal (C104; Carr et al., 2017), long prefrontolacrimal process of the frontal, terminating anterior to termination of the prefrontonasal process (C153; Voris et al., 2020)*. Note that this list of synapomorphies is not exhaustive as there are many which are shared between Teratophoneus and Lythronax, where the state cannot be assessed for Dynamoterror.
