Reptilia - Squamata
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.
|M. A. Norell et al. 2007||Distinguished from Cherminotus longifrons and other closely related varanoids by the following character states: nasals paired; presence of aperture between premaxilla and maxilla (the premaxillary fenestra sensu Gauthier, 1982; see also Gao and Norell, 1998); anteromedial process of maxilla separating premaxilla from septomaxilla; dorsal septomaxillary foramen strongly reduced and close to midline (from Gao and Norell, 2000). Sharing with Aiolosaurus oriens character states including presence of a premaxilla-maxilla aperture; dorsal septomaxillary foramen strongly reduced and close to midline. Distinguished from Aiolosaurus oriens and other closely related varanoids by the following derived character states: presence of paired mystery bones roofing the nasal/frontal suture; absence of dermal sculpturing on the skull bones (region unpreserved in Aiolosaurus oriens); premaxillary nasal process broader than deep; premaxilla-maxilla aperture large and rounded; premaxillary teeth 12 (as opposed to 7 in Aiolosaurus oriens); maxillary teeth 12–13 (Aiolosaurus oriens 10 at most).|
