Which was the smartest dinosaur?
Although there is no straight way to measure a dinosaur's intelligence, one of the few probable measures of intelligence might be a big brain in a small body. The genus that perhaps fits this description best was the Cretaceous bird-like dinosaur Troodon, which also may have had binocular hallucination (depth perception) and outstanding eyesight and was built for speed. Even so, this dinosaur was probably not as intelligent as most new birds and mammals.
