FIGURE 21 in The anatomy and diversity of the pterosaurian sternum

FIGURE 21. Figure of the diversity of shapes of pterosaur sterna plotted onto a dendrogram of pterosaurian relationships (images not to scale). This is based on Zhou et al., 2021 (non-pterodactyloids), Andres, 2021 (ctenochasmatids), Hone et al., 2020 (other pterodactyloids). Where there are multiple specimens, preference has been given to adult specimens and all sterna are shown in ventral view except Santanadactylus and Scaphognathus which are in dorsal view.
