Larry Witmer and a few other researchers from Ohio and Calgary universities will be presenting research in November about a new method of estimating dinosaur intelligence. Apparently they've found a way to calculate evolutionary changes to brain structure, and the preview states that existing calculations of dino encephalisation quotients are too low.
The sample group will be Stegosaurus, Euoplocephalus, Hypacrosaurus, Pachyrhinosaurus, Diplodocus, Majungasaurus and Troodon, they'll be compared with birds and reptiles. I'm hoping the findings make their way online quickly.
