Diagnosis
ReferenceDiagnosis
D. M. Martill 2011Unwindia trigonus can be distinguished from other pterosaurs by the reduced dentition of the maxilla/premaxilla of only 7 tooth pairs all of which lie anterior to the nasoantorbital fenestra: this is apomorphic for the species. The teeth are of similar size, distinguishing them from the marked heterodonty of other Santana formation tooth-bearing pterosaurs.
