| Heptasteornis andrewsi Harrison & Walker, 1975 |
Heptasteornis is the name given to a dubious genus of small dinosaur from the Late Cretaceous. The type (and only known) species is Heptasteornis andrewsi, described by Harrison and Walker in 1975. The fossil was discovered in Romania.
It is sometimes considered synonymous with Bradycneme or Elopteryx, but given the fragmentary nature of the fossils, little is known about this animal. The genus is thus considered a nomen dubium.
It was reassessed as an alvarezsaurid by Naish (2004).
