Cited by genera

• Bahariasaurus

  Argued Deltadromeus agilis is a junior synonym of Bahariasaurus.

• Carcharodontosaurus

  Recovered C. iguidensis outside Carcharodontosaurus sensu stricto, suggesting it warrants its own genus.

• Ceratosuchops

  Left the Ceratosuchops–Riparovenator synonymy open, deferring to a future detailed comparison.

• Eocarcharia

  Argued the Eocarcharia hypodigm is chimeric, reinterpreting the holotype postorbital as a spinosaurid.

• Huaxiagnathus

  Proposed that Sinotyrannus is a mature individual of Huaxiagnathus, on shared ilium morphology and differences attributed to growth.

• Kryptops

  Finds the original hypodigm chimerical, an abelisaurid maxilla with allosauroid postcrania, and scores them as separate units.

• Riparovenator

  Left the Riparovenator–Ceratosuchops synonymy open, deferring to a future detailed comparison.

• Sauroniops

  Refers a new specimen to Sauroniops and takes it to support the genus's validity and distinction from other carcharodontosaurids.

• Sinotyrannus

  Proposed Sinotyrannus as the adult morphotype of the compsognathid Huaxiagnathus.

• Tameryraptor

  Recovered Tameryraptor as the sister taxon of Carcharodontosaurus saharicus.

• Taurovenator

  Recovered Taurovenator only as an unstable wildcard within Carcharodontosauridae.

• Thecocoelurus

  Recovers the Angeac-Charente theropod, the comparison material for the ornithomimosaur referral, within Abelisauroidea.

• Valdoraptor

  Recovers the Angeac-Charente theropod, the comparison material for the ornithomimosaur referral, within Abelisauroidea.
