Abstract: A new azhdarchoid pterosaur from the Upper Cretaceous of Patagonia is described. The material consists of an incomplete edentulous lower jaw that was collected from the upper portion of the Portezuelo Formation (Turonian-Early Coniacian) at the Futalognko site, northwest of Neuquén city, Argentina. The overall morphology of Argentinadraco barrealensis gen. et sp. nov. indicates that it belongs to the Azhdarchoidea and probable represents an azhdarchid species. The occlusal surface of the anterior portion is la… Show more

“…the occlusal (=dorsal) surface is pierced by several foramina, which are more than those of the upper jaw, but much fewer than those in tapejarines (Kellner and Campos 2007, Andres et al 2014, Manzig et al 2014) and similar to the low number present in basal tapejarines (Kellner 2013, Pêgas et al 2016. the ventral surface of the symphysis is blunt and bears a small and thick (Kellner and Calvo 2017). the occlusal surface is anteriorly flattened and becomes slightly concave posteriorly.…”

“…Despite the inherent difficulties of establishing the diet of extinct vertebrates with no suitable modern analogues such as pterosaurs, the following feeding habits have been proposed for derived pterodactyloids 37 , mainly based on their dentition (or absence of teeth) and the shape of their rostra: piscivory for Anhangueridae and their kin 30,38–40 , Ikrandraco 41 , Pteranodontidae 30 , Nyctosauridae 42 , Chaoyangopteridae 43 , and Thalassodrominae 44 ; frugivory for Tapejarinae 45,46 ; durophagy for Dsungaripterus and related species 30 ; insectivory for Nemicolopterus 47 ; scavenging for Istiodactylus 21,22 ; cutting or ploughing through unconsolidated sediments for Argentinadraco 48 , and terrestrial stalking for the long-necked azhdarchids 49 . The dentition of Mimodactylus differs from all of them, suggesting that this lineage of derived pterodactyloid had a different feeding habit.…”
