_Dromaeosauridae_ sensu Sereno (a stem-based clade excluding _Troodon_; I
forget what the internal specifier was, although by draft PhyloCode rules it
should be _Dromaeosaurus albertensis_) would work, and it might also include
There is, however, another definition of _Dromaeosauridae_:
Clade(_Dromaeosaurus_ + _Velociraptor_). This would include _Velociraptor_
(obviously) and _Deinonychus_, but probably not _Sinornithosaurus_.
However, the sickle-clawed trait might be basal to _Eumaniraptora_, seeing as
it's present in both _Deinonychosauria_ (now including _Troodontidae_, it
and at least one basal avialan (_Rahonavis ostromi_).
