ABSTRACT Remains of a pterodactyloid pterosaur wing from the Two Medicine Formation (Campanian) of Montana were described by Padian (1984). The bones were preserved in a limestone concretion, which has now been further prepared to expose additional material. This allows some correction and further elaboration of earlier observations. The specimen (YPM-PU 22446) is now referred to the family Azhdarchidae, and provisionally to the genus Quetzalcoatlus.
