Dromaeosaurids: have teeth.  "Elmisaurids" (aka caenagnathids): do not have
teeth.  The "new" specimen of the caenagnathid _Chirostenotes pergracilis_
to be published soon in JVP will confirm the long-held suspiscion that the
toothless jaws called "_Caenagnathus_" and the skeletal material called
"elmisaurids" are from the same animal.
