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
V. R. Alifanov and R. Barsbold 2009Presacral vertebrae opisthocoelous. Claw of major digit of manus longer than preungual phalanx. Postacetabular process of ilia oriented subhorizontally. Pubic process of this bone relatively small, ischiadic process large, laterally extended. Ilia with well-pronounced supra-acetabular process. Pubes and ischia tightly connected. Greater and lesser trochanters fused into single crest. Distal part of fibula reduced. Third metatarsals wedging out proximally.
F. E. Novas et al. 2013Parvicursorines are diagnosed by several bizarre derived traits, such as opisthocoelous cervical and anterior thoracic vertebrae, procoelous synsacrum, a biconvex vertebra uniting the dorsal and sacral vertebral series, procoelous caudal vertebrae, and an opisthopubic pelvis with rod-like posteroventrally oriented pubis and ischium, recalling the condition present in derived ornithurine birds
X. Xu et al. 2013Dorsal vertebrae opisthocoelous and without hyposphene−hypantrum articulations, dorsal parapophyses elevated to level of diapophyses, dorsal infradiapophyseal fossae hypertrophied, posterior sacral vertebrae with hypertrophied ventral keels, anterior caudal vertebrae with anteriorly displaced transverse processes, metacarpal II that is mediolaterally wider than proximodistally long and dorsoventrally shallow, bears two articular facets on the proximal surface, and lacks collateral ligamental fossae, manual ungual II with ventral axial groove and without flexor tubercle, tibial distal end with lateral malleolus anteroposteriorly expanded, astragalar ascending process L−shaped, and specialized arctometatarsalian condition with metatarsal III shorter than metatarsals II and IV. Other possible parvicursorine synapomorphies include: posterior dorsal vertebrae with small and posterodorsally oriented neural spines; biconvex vertebra near posterior end of dorsal series; keeled and boat−like sternum with median groove along midline; manual phalanx II−2 longer than II−1; supracetabular crest of ilium more prominent anteriorly than posteriorly; metatarsus longer than femur; metatarsals II and IV subequal in length; and pedal digit III more slender than digits II and IV.
