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
| Reference | Diagnosis | |
|---|---|---|
| R. B. J. Benson et al. 2010 | Neovenatorid theropods with the following unambiguous synapomorphy: long, gracile metatarsals (III) with a ratio of length to minimum width ≥12.5. Incomplete knowledge of Chilantaisaurus and Neovenator means that other potential synapomorphies of Megaraptora, pertaining to cursorial hind limbs (Fig. 1j–k) and pneumatic caudal vertebrae (Fig. 1c), are only recovered under DELTRAN optimisation (see “Electronic supplementary material”). |
