Weird, huh?  _Deltadromeus_ is a noasaurid according to one source.  In 
fact, I recently learned that this family is in the process of undergoing a 
major revision, and may include quite a number of genera.

Most recent phylogenies have recovered alvarezsaurids as bona fide members 
of the Maniraptora, in between _Ornitholestes_ and the 
Eumaniraptora+(Oviraptorosauria+Therizinosauroidea) clade (="Aviremigia", 
although I dislike anatomy-based definitions)
