A new pterodactyloid pterosaur from the Santana Formation (Cretaceous) of Brazil

摘要

A partial skull comprising fused maxilla/premaxilla and palate of a ctenochasmatoid pterosaur from the Santana Formation of the Araripe Basin in NE Brazil is named as the new genus and species Unwindia trigonus gen. et sp. nov. on account of its long slender rostrum, isodonty with raised dental alveoli and dentition of seven tooth pairs restricted to the portion of the rostrum anterior to the nasoantorbital fenestra. Unwindia is assigned to the Ctenochasmatoidea, and is probably basal within the clade.
