Re: Tarsitano's challenges
<<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).
