Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| O. W. M. Rauhut et al. 2016 | Large megalosauroid theropod diagnosable by the following autapomorphies: Lacrimal with small oval depression in the antorbital fossa anterior to the lacrimal fenestra; very short and high anterior process of the lacrimal, its length being less than half the height of the bone; postorbital with a transversely notably concave orbital facet in the dorsal part of its anterior side, with markedly raised lateral and medial margins; oblique ridge on the medial side of the fibula at about the level of the iliofibularis tubercle; proximal part of the ascending process of the astragalus deflected laterally, resulting in a marked kink in the lateral margin of this process.
Several further characters can also be used to diagnose the new taxon; although at least several of them are found in some other non-coelurosaurian theropod taxa, and the distribution of others is unclear due to lack of detailed descriptions, their combination is unique to Wiehenvenator albati: Anterior margin of the nasal process of the premaxilla offset from anterior margin of premaxillary body by a slight concavity (also present in Sciurumimus); anteriormost premaxillary tooth considerably smaller than second premaxillary tooth (also present in spinosaurids); medial premaxillary foramen placed over the second alveolus, not the third; maxillary antorbital fossa reduced; small pneumatic depression (excavatio pneumatica) on the ascending process of the maxilla (also present in Ceratosaurus and some allosauroids). |
