“…We interpreted the elongate necks, hypertrophied, stork-like rostra, and distinctive limbs of azhdarchids as adaptations to "terrestrial stalking", a lifestyle akin to that of modern ground hornbills and large stork species in which small foodstuffs (e.g., fruit, carrion, invertebrates, and small vertebrates) are procured during sustained periods of terrestrial foraging. Corroborating evidence for this hypothesis is provided by (i) Haenamichnus trace fossils, tracks referred to azhdarchid pterosaurs which record an efficient, parasagittal gait, presumably typical for the group (Hwang et al 2002); (ii) azhdarchid wing planform, which is probably better suited for flight in terrestrial settings than aquatic ones (assuming that azhdarchid planforms corroborate with fore-and hindlimb proportions, as is indicated by analyses of wing membrane distribution: see Witton 2008 andElgin et al 2011); and (iii) a strong bias linking azhdarchid fossils to continental depositional settings (Witton and Naish 2008). Other workers have since reported anatomical details of the azhdarchid skeleton that add further support to the terrestrial stalking hypothesis (Carroll et al 2013).…”
