<<.How easy is it to peck an animal to death. Without teeth, especially replaceable teeth, it would be extremely hard to kill any large animal, or catch enough small ones to grow extremely big. >>
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)?
