First occurrence of azhdarchoid pterosaurs in the Gault Formation (Lower Cretaceous,Albian) of England,United Kingdom with a brief review of Gault pterosaurs

Pterosaurs are a rare component of the Early Cretaceous (Albian) Gault Formation of southern England. The only named taxon reported, ‘Pterodactylus’ daviesii Owen, 1874, is widely regarded as a nomen dubium or as Pterodactyloidea incertae sedis, while most other material can be referred to Pterodactyloidea indet. Here we describe a fragmentary humerus and elongate mid-series cervical vertebra both from the Gault Formation of Kent, southeast England that can be referred to the edentulous pterodactyloid clade Azhdarchoidea. The cervical vertebra is identified as being from a non-tapejaromorph azhdarchoid on account of its reduced neural spine, a neural arch confluent with the centrum, a neural canal that is subsumed into the centrum and the lack of foramina on the lateral surfaces of the centrum. The humerus is referred to Azhdarchoidea on account of its sub-rectangular distal end.
