Is t rex smart

I actually had the largest brain of any dinosaur, about the size of a human's. It had binocular vision (it could see in 3-d), it had large olfactory bulbs (it had a good sense of smell), and its ear canal was highly developed (it could hear very well). However, a human's brain is to a 5-6-foot long body- T. rex's brain was just to a 5-6-foot-long head! It was smart, but smaller dinosaurs like Velociraptor and Troodon were more intelligent.
