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
K. Matsui and S. Kawabe 2015Emended diagnosis for the genus (humeral characters only).—The greater tubercle extending toward the prox- imal side above the head, a large greater tubercle, a dis- tinct, medially projected lesser tubercle located on the medial side, the intertubercular groove located on the medial side, a shallow and narrow intertubercular groove, an oval head that is slightly convex at the distal end, and absence of the deltoid tuberosity.
K. Matsui et al. 2018Relatively larger femoral head with respect to the proximal width than Neoparadoxia and Ashoroa; lesser trochanter is bulged to inside; lesser angle of intertrochanteric crest than Behemotops, Neoparadoxia, Ashoroa and Desmostylus; lesser trochanter closer to femoral head than Desmostylus, Cornwallius and Behemotops. For diagnosis of other parts, see [2,34].
