<<Oviraptorids have pnuematic quadrates (Maryanska and Osmolska, 1996)>>

<Not to mention tyrannosaurids, some ornithomimids and troodontids. Also, Confuciusornis lacks this character.>

Not to mention _Archaeopteryx_, apparently lacking both quadrate and articular pneumaticity (Elzanowski and Wellnhofer, 1996; Walker, 1985).
