	""Ornithocheirus"" "buenzeli" (often mis-spelled "O. bunzeli") is a pterosaur species known from parts of a humerus (upper arm bone) and part of a lower jaw found in late Cretaceous period (Campanian) rocks of the Grünbach Formation, Austria. While it has traditionally been classified in the genus "Ornithocheirus", it is more likely an azhdarchid, though due to the fragmentary nature of known fossil remains, it is considered a "nomen dubium".
