_Noasaurus_ was an abelisauroid ceratosaur, not an ornitholestoid. IIRC,
its "killer claw" is morphologically quite distinct from those of the
coelurosaur groups with "killer claws", troodontids and basal
paravians/eumaniraptors (including dromaeosaurids).

It'd be interesting if there was some kind of "noasaur vs. dromaeosaur"
thing going on in the Cretaceous of South America -- if only we had more
noasaur fossils.
