PterygornisPterygornis is an extinct monotypic genus of enantiornithean dinosaur that lived in East Asia during the Aptian stage of the Early Cretaceous epoch.EtymologyThe generic name Pterygornis is derived from the Latin word ‘pteryg’, meaning wing, and the Ancient Greek word ‘ornis’, meaning bird. The specific epithet of the type species, Pterygornis dapingfangensis, is derived from the town of Dapingfang, where its fossils were found.
