Fig. 3 in Azhdarchid pterosaurs: water-trawling pelican mimics or "terrestrial stalkers"?

Fig. 3. Comparing mandibular bowing in pelican (A) and azhdarchids (B, C), showing areas measured for relaxed jaws (0% ext., A1, B2, C2), jaws partially extended (50% ext., A2, B3, C3), and fully extended (100% ext., B4, C4). Shaded regions denote areas measured for comparison; darker shading on azhdarchid jaws reflects regions measured for "gular alone" measurements. A. Pelecanus occidentalis skull and mandible in ventral view, modified from Meyers and Meyers (2005). B. Quetzalcoatlus sp. (TMM 42161- 2) jaw in dorsal view (B1), redrawn from Kellner and Langston (1996). C. Bakonydraco galaczi (MTMGyn/3) jaw in dorsal view (C1), after Ősi et al. (2005). Scale bars 100 mm.
