FIGURE 2. Unique combination of features of Austrocheirus isasii compared with other basal theropods. Metacarpals III in lateral views of Austrocheirus (A), Dilophosaurus (B), and Allosaurus (C); tibiae in distal views of Austrocheirus (D), Berberosaurus (E), Velocisaurus (F), and Masiakasaurus (G); metatarsals III in medial views of Austrocheirus (H) and Masiakasaurus (I); and pedal phalanges in side views of Austrocheirus (J), Elaphrosaurus (K), Velocisaurus (L), and Majungasaurus (M). Note the presence of the following autapomorphies in Austrocheirus: metacarpal III with a posteriorly tapering shaft and a posteriorly diplaced collateral fossa (A–C); pedal phalanges with a dorsal tubercle above the collateral fossa (J–M). Abbreviations: a...
