FIGURE 8. Analysis of eupterodactyloid pterosaur relationships showing the phylogenetic position of Luchibang. Major clades are labelled and numbers represent the numbers of characters (see Supplemental Data S1) that are unambiguous apomorphies of each clade (please see Corrigendum).
FIGURE 9. Analysis of pterosaur limbs proportions comparing humerus length to hindlimb length. Istiodactylids are represented by squares, ornithocheirids by diamonds, pteranodontids by triangles, ctenochasmatids by crosses, and azhdarchoids by asterisks. Luchibang is represented by a square containing a circle. Silhouettes courtesy of, and used with permission from, Mark Witton.
