Reptilia - Mixosauridae
It was considered a nomen dubium by Motani (1999) and McGowan and Motani (2003); it was recombined as Barracudasaurus maotaiensis by Jiang et al. (2005).
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.
|D.-Y. Jiang et al. 2005||"Potential autapomorphies of Barracudasaurus include the following. Premaxillary teeth with rounded cross-section, elongate, conical and pointed, very widely spaced and apparently few in number (probably < 15). Maxillary teeth larger than premaxillary teeth. Anterior maxillary teeth robust, conical and bluntly pointed. Posterior maxillary teeth with anteroposteriorly slightly elongated cross-section, very short, robust and blunt. Humerus without postaxial facet, radial facet slopes distinctly anteroproximally. Coracoid with reduced posterior extension. Interclavicle of triangular shape. Clavicle slender, probably without medial thickening. Plesiomorphic features which aid in identification include the following. Small mixosaurid, skull length does not exceed 250 mm. Teeth subthecodontously implanted, roots show labyrinthodont infolding. All teeth show strong distinct apicobasal ridges. Maxilla short anteriorly. Postorbital skull segment long, about one-half the diameter of the orbit. A ventral extension of the postorbital covers the postorbital process of the jugal laterally. A deep postjugal incisure (jugal-quadratojugal notch) is present, bordered dorsally by the quadratojugal, squamosal and postorbital. No external contact between jugal and quadratojugal. Jugal very slender and fragile. Postorbital separates postfrontal and supratemporal. Sagittal crest low but extending anterior to the external naris. No postaxial ossifications of the forefin."|
