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.
|H. F. Osborn 1903||Probably littoral, shell-eating Diaptosauria. Premaxillaries decurved, edentulous. Maxillaries edentulous. Palatines (palatopterygoids) with small tesselated teeth. A single narial opening. Vertebrae amphicoelous, imperforate. Interciavicle T-shaped. Coracoid and procoracoid suturally separate (in certain forms). Pubis and ischium more or less continuous.|
