==Classification== ''Velociraptor'' is a member of the group [[Eudromaeosauria]], a [[Synapomorphy|derived]] sub-group of the larger family Dromaeosauridae. It is often placed within its own subfamily, [[Velociraptorinae]]. In [[phylogenetic taxonomy]], Velociraptorinae is usually defined as "all dromaeosaurs more closely related to ''Velociraptor'' than to ''[[Dromaeosaurus]]''." However, dromaeosaurid classification is highly variable. Originally, the subfamily Velociraptorinae was erected solely to contain ''Velociraptor''.<ref name=barsbold1983/> Other analyses have often included other genera, usually ''Deinonychus'' and ''[[Saurornitholestes]]'',<ref name=currie1995>{{cite journal|doi=10.1080/02724634.1995.10011250 |last=Currie |first=Philip J. |author-link=Phil Currie |year=1995 |title=New information on the anatomy and relationships of ''Dromaeosaurus albertensis'' (Dinosauria: Theropoda) |journal=Journal of Vertebrate Paleontology |volume=15 |issue=3 |pages=576–591 |bibcode=1995JVPal..15..576C |url=http://vertpaleo.org/publications/jvp/15-576-591.cfm |url-status=dead |archive-url=https://web.archive.org/web/20071117132451/http://vertpaleo.org/publications/jvp/15-576-591.cfm <!--Added by H3llBot--> |archive-date=17 November 2007 }}</ref> and more recently ''Tsaagan''.<ref name=norelletal2006>{{cite journal|last1=Norell|first1=M.

All dromaeosaurids have also been referred to the family [[Archaeopterygidae]] by at least one author (which would, in effect, make ''Velociraptor'' a flightless bird).<ref name=paul2002 /> In the past, other dromaeosaurid species, including ''Deinonychus antirrhopus'' and ''Saurornitholestes langstoni'', have sometimes been classified in the genus ''Velociraptor''. Since ''Velociraptor'' was the first to be named, these species were renamed ''Velociraptor antirrhopus'' and ''V. langstoni''.<ref name=paul1988>{{cite book |last1=Paul|first1=G.
