Maniraptors (3)

http://en.wikipedia.org/wiki/Microraptorinae#Relationship_with_birds
"Martin believes that maniraptorans are secondarily flightless birds, and that birds evolved from non–dinosaurian archosaurs [pterosaurs according to my thesis], so that most of the species formerly called theropods [ie. the maniraptors] would now not even be classified as dinosaurs.^[43]"
