"Some" processing of food need not have been any more than in 
tyrannosaurids...! How much it was should be inferred from the shapes and 
occlusion or lack thereof of the postcanine teeth, and that is, AFAIK, not 
impressive by mammalian or notosuchian standards.

Disclaimer: although I attended the IPC and gave two talks there, I missed this 
talk. All of paleontology was crammed into eleven parallel sessions, so there 
were often five interesting talks at the same time. We all whined a lot.
