How intelligent were dinosaurs?

Measuring the intelligence of a dinosaur is a very difficult thing. One of the things that people have used is called EQ coefficient which is basically how large the brain is relative to the body size this has its problems and doesn't have its problems. It's not just how big the brain is but how big certain parts of the brain are and we know from living animals that animals which smell very well, that they have very large olfactory lobes in in their brains. Animals which, you know, see very well, have very accute vision and stuff, have greatly expanded optic lobes. So a lot of this work is just starting to be done and really the advent of cat scan technology which allows us to be able to reconstruct the brains of extinct dinosaurs, has really pushed a long way in just a few years, but again the work is very preliminary and its still very hard to correlate specific brain features with particular either senses or aspects of intelligence.
