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
P. D. Mannion and A. Otero 2012Argyrosaurus can be diagnosed by five autapomorphies (marked by an asterisk), as well as a unique combination of character states: (1) medial margin of humerus forms a transversely wide ridge that projects prominently anteriorly∗; (2) midshaft of humerus extremely compressed anteroposteriorly (transverse to anteroposterior width ratio = 2.6)∗; (3) transverse width of distal end of radius only slightly greater than midshaft width (ratio = 1.3)∗; (4) radius is subtriangular in distal end view∗; (5) presence of ossified carpals; (6) extreme elongation of metacarpals (longest metacarpal to radius length ratio = 0.6)∗; (7) metacarpals II and III longest elements in metacarpus.
