Rahonavis
Makovicky and colleagues consider Rahonavis to be closely related to the South American dromaeosaurids Unenlagia and Buitreraptor, and thus a member of the subfamily Unenlagiinae. Norell and colleagues (2006) also found Rahonavis to lie within the Unenlagiinae, as the sister taxon to Unenlagia itself.<ref name="norelletal2006">{{cite journal|last=Norell|first=M.A. | display-authors = etal |year=2006|title=A new dromaeosaurid theropod from Ukhaa Tolgod (Omnogov, Mongolia)|journal=American Museum Novitates|issue=3545|pages=1–51|doi=10.1206/0003-0082(2006)3545[1:ANDTFU]2.0.CO;2|url=https://zenodo.org/record/5386073 }}</ref> A 2007 study by Turner and colleagues again found it to be closely related to Unenlagia.  However, studies published since 2009 that have found many traditional "dromaeosaurids", including the unenlagiines, closer to Avialae than to dromaeosaurines. A cladistic analysis recovered Rahonavis as a probable relative of Jeholornis and Jixiangornis.Andrea Cau (2018). "The assembly of the avian body plan: a 160-million-year long process" (PDF).
