Fig. 1 in Evidence for a sauropod-like metacarpal configuration in stegosaurian dinosaurs

Fig. 1. Manual skeletal configuration in stegosaurs and other dinosaurs. A. Cladogram of Dinosauria with proximal views of metacarpals, showing convergent evolution of tightly curved metacarpal arc in Sauropoda and Thyreophora; Herrerasaurus after Sereno (1993), sauropods after Bonnan (2003), Camptosaurus after Carpenter and Wilson (2008), and Peloroplites after Carpenter et al. (2008). B. Articulated manus of the sauropod Camarasaurus lentus, CM 11338 (after Gilmore 1925). C. Articulated manus of the stegosaur Stegosaurus armatus, USNM 4934 (right, after Gilmore 1914) as found in situ, showing that the metacarpals form a vertical tube (C. lentus) or semi−tube (S. armatus). D. Articulated metacarpals of the stegosaur Kentrosaurus aethiopicus in proximal view (modified from Hennig 1925). E. Previous, incorrect reconstruction of the manus of USNM 4937 (Gilmore 1914), a stegosaur of indeterminate genus and species (Maidment et al. 2008), in cranial view, showing unnatural gap between carpals (arrow) (likely Stegosaurus sulcatus, Upper Jurassic, USA; see text). F. Previous, incorrect reconstruction of the manus of USNM 4937 (Gilmore 1914) in proximal view, showing unnatural gaps between metacarpals (arrows). G. Incorrectly articulated right hand of the stegosaur USNM 4937 viewed from above. H. Incorrectly articulated right hand of the stegosaur USNM 4937 viewed from obliquely behind and to the left. I. Cranial view of mounted right forelimb of Stegosaurus armatus AMNH 650, showing distal contact between radius and ulna; carpus and manus are cast from a different specimen.
