Could a more complex folded cortex
(assuming dinosaurs HAD much of a cortex - even the brainiest of birds have much smaller cortices than mammals of equivalent EQ)?
Or would the size and number of blood vessels entering the brain case be a better indicator of brain complexity (I'm assuming more complex brains need more nurishment).
That's probably correlated to size...
While I'm asking questions; would there be an upper size limit for brain volume for terrestrial animals, above which there is little improvement in function?
Does brain size have anything to do with function?
