Big oviraptorosaurs _would_ be hardly understandable(in this sense) *if* they turned out to  be carnivorous (or at least omnivorous); IIRC the newly found "Chirostenotes" specimens are quite big(Dilophosaur-sized?).
Does anybody have any suggestion about the dietary habits of those dinos(in particular the big ones)?
