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.
|K. -Q. Gao and M. A. Norell 1998||Sharing with extant xenosaurids the following derived characters: strong interorbital constriction of fused frontals; jugal-squamosal contact; dermal vermiculate rugosities on skull roof elements; postorbital branch of jugal ornamented. Distinguished from all other closely related taxa including Xenosaurus and Shinisaurus by the following autapomorphies: lacrimal absent, with anteroventral process of jugal contacting prefrontal; maxilla contributes to formation of ventral border of orbit; caudoventral process of jugal ventrally directed; fenestra exochoanalis distinctively short and elliptic; presence of midline contact of palatines anteriorly; palatine rectangular and strongly widened, suppressing suborbital fenestra into narrow and elongate opening; presence of vertical crest anteriorly on quadrate; condyle-fossa articulation for both squamosal and supratemporal with cephalic condyle of quadrate; descending process of parietal subrectangular, elongated, and laterally compressed; epipterygoid slanted strongly posterodorsally; marginal process of supraoccipital prominent and well-ossified; presence of strong adductor crest dorsolaterally on surangular; marginal teeth extremely fine, numerous, and having comblike arrangement; strong posterior extension of neural spone of axis over entire third cervical.|
