Nurhachius (the name derived from Nurhaci) was a genus of istiodactylid pterodactyloid pterosaur from the Barremian-Aptian-age Lower Cretaceous Jiufotang Formation of Chaoyang, Liaoning, China. It is based on IVPP V-13288, a partial skull and skeleton. The skull is very similar to that of Istiodactylus, which lived at about the same time in what is now England. It differs from Istiodactylus in several details, including a lower skull, different jugal, teeth compressed side to side, and a slight curve to the upper margin of the lower jaw. Its wingspan was estimated at 2.4-2.5 m (7.87-8.20 ft).1 Its position as closely related to Istiodactylus was supported by another publication.2 References
