We had believed that T-Rex was the biggest carnivore dinosaur for a big while. Although currently Spinosaurus takes that prize, T-Rex is still the hero of children. T-Rex had a big skull comparing with its body. This means T-Rex could be one of the most intelligent dinosaur with a very fast instinct. A strange thing of T-Rex is its small arms. Its arms were just the size of human’s arm which might be useless with that massive body.
