What is "hongshanopterus"

Hongshanopterus is a genus of istiodactylid ornithocheiroid pterodactyloid pterosaur from the Lower Cretaceous Jiufotang Formation of Liaoning, China. It is based on IVPP V14582, a skull and neck vertebrae of a single individual. The teeth had triangular crowns and were flattened from mouth side to "lip" side, like those of other istiodactylids. Hongshanopterus was less derived than other istiodactylids, however, by having a tooth row that extended beyond the first third of the skull, and by having some teeth that were directed backwards. The type species is H. lacustris.
