== Discovery and naming == In 1999, paleontologist Patricia A. Holroyd described a partial right maxilla from 'Quarry M' of the Jebel Qatrani Formation near the Faiyum Oasis of Egypt as belonging to a new species of Pterodon, P. syrtos. The specific name, syrtos, is a Greek word meaning "carried along by a stream", referencing the preservation of the holotype in a point bar depositional environment.
