Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. T. Carrano and S. D. Sampson 2008 | It is not clear whether Velocisaurus preserves autapomorphies (Rauhut 2003: 33), but it is probably a distinct taxon based on its provenance. | |
| F. Brissón Egli et al. 2016 | Small-sized theropod (Table 1) dinosaur diagnosable by the following combination of characters (autapomorphies marked by an asterisk, *): femur with proximal end showing a strongly subtriangular cross-section with lateral and medial surfaces converging anteriorly and resulting in a thick dorsoventral crest*; tibia coelurosaur-like, long and slender, with its distal end anteriorly flat, bearing a large surface to accommodate a tall and wide ascending process of the astragalus; metatar- sals II and IV with rod-like shafts, differing from the laminar outer metatarsals present in other small abelisauroids*; and pedal phalanx IV-1 anteroposteriorly short, dorsoventraly tall, transversely compressed on its dorsal half, and medially curved*. |
