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.

Diagnosis
ReferenceDiagnosis
T. Sato 2005"Slender teeth with fine striation, short and wide supratemporal fenestra, vertical suspensorium, anterior projection of cultriform process into the interpterygoid vacuity, short extension of the pterygoid posterior to the interpterygoid vacuity, short quadrate process of pterygoid, chevron facets on posterior edge of centrum, straight ilium. Dolichorhynchops was monospecific until the current study. Only the features that are confirmed in D. osborni (Carpenter, 1996; O'Keefe, 2004) and the new species are listed above as diagnostic."
R. Schmeisser McKean 2012Short and high sagittal crest, short and wide temporal fenestra, vertical suspensorium, ectopterygoid lacking an anterior process, broadened posterior end of parasphenoid, pterygoid extends posterior to interpterygoid vacuity, 17-20 pairs of teeth in mandibular symphysis, 19e21 cervical vertebrae, posterior bend in midshaft of scapula, epipodials shorter than broad, lateral spur on coracoids.
