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
L. E. Zanno et al. 2009Nothronychus can be differentiated from all other therizinosaurs by the following autapomorphies: scapula with dorsoventrally tapering blade; distinctly subcircular obturator process; ovoid, dorsoventrally elongate obturator foramen (maximum length greater than 200% of maximum width); contact between pubis and ischium restricted to proximal half of obturator process; and presence of a deep notch between ventral aspect of obturator process and cranial ischial shaft.
