Istiodactylidae (Howse, Milner & Martill, 2001)
Istiodactylus was originally classified as Ornithodesmus based on a Holotype which was misclassified as pterosaur. Following reassignment of the Holotype, the existing fossils had to be re-named.
Nurhachius was originally considered as a Dsungeripterid and has now been classified Istiodactylid, though there is some doubt about this classification.
