You need to try this one again, Brian. Heptasteornis was recently discovered to be an alvarezsaurid!

Naish, D. & Dyke, G.J. 2004. Heptasteornis was no ornithominid, troodontid, dromaeosaurid or owl: the first alvarezsaurid (Dinosauria: Theropoda) from Europe. Neues Jahrbuch für Geologie und Paläontologie, Monatshefte 2004 (7): 385-401.

Yep, it was originally classified as a large owl, later as a troodontid based on the astragalus. Some consider it a synonym of Elopteryx, and now a alvarezsaurid. I'll make changes to it now that there is updated evidence.

Thanks,
