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.
|J. Lindgren and M. Siverson 2005||Cervical and dorsal vertebrae very large relative to overall size of the animal. Marginal tooth-crowns small (up to 12.5 mm high), conical and subcircular in cross section. Carinae on marginal teeth inconspicuous. Enamel on marginal crowns thick at apex but very thin at base of crown. Surface of enamel either smooth or developed into faint, closely spaced, and undulating striations (particularly on the lingual face). Twenty-two teeth in dentary.|
