Once again I will mention the possibility that the _Avimimus_ premax 
does not go with the cranium of the genus, but may instead be from a 
hadrosaur. 

This may or may not be correct. But Pete's contention that a 
crennulated premax would be suggestive of oviraptorosaurian 
affinities are a little suspect aren't they? A vaguelly crennulated 
premax has been figured for _Oviraptor mongoliensis_, but I'm not 
convinced these represent proper crennulations (which should be 
denticulate). And are they present in other oviraptorosaurs? Not as 
far as I'm aware.
