Phylogenetic affinities of Saltriovenator and evolution of the hand in Theropoda. Reduced strict consensus of the shortest trees found by the phylogenetic analysis after pruning of Lewisuchus and Teleocrater. Numbers at nodes indicate decay index. Inferred manual phalangeal formula for selected nodes indicated below clade names. Hands of representative members of the avian stem (bold names) in extensor view (Herrerasaurus in flexor view), medial side at left, missing elements in white based on ancestral states inferred at least inclusive node containing the taxon. Red star indicates loss of metacarpal V, blue stars indicate multiple independent losses of metacarpal IV among tetanurans. Drawings by A. Cau.
