Heptasteornis

Dubious extinct genus of reptiles

Heptasteornis is the name given to a dubious genus of alvarezsaurid dinosaur from the Late Cretaceous. The type species is Heptasteornis andrewsi, described as a presumed gigantic prehistoric owl in 1975. It was previously included in Elopteryx nopcsai and indeed the holotypes of both were believed to be from the same individual as they were discovered, and initially were assigned the same specimen number. This appears to be in error however.
