KIDS TRIVIA

Detailed explanation-1: -A T. rex, for example, had an EQ of about 2.4, compared with 3.1 for a German shepherd dog and 7.8 for a human-leading some to assume it was at least somewhat smart.

Detailed explanation-2: -By studying the brain size in comparison to the actual size of the dinosaur and examining some of its physical attributes to determine how it might have behaved, scientists now think Troodon formosus, a relatively small dinosaur from the Late Cretaceous, was the smartest dinosaur ever.

Detailed explanation-3: -Utahraptor was the most intelligent animal in its world and information about Deinonychus suggests it may have been a pack hunter. As it is thought that packs of Deinonychus hunted 30-foot-long relatives of the iguanodons, it is easy to envision a pack of Utahraptors taking on a 50-foot elephantine sauropod.

Detailed explanation-4: -Troodon, a human-size theropod of the late Cretaceous period, has become the poster lizard for dinosaur intelligence, thanks to a decades-old (and somewhat whimsical) paper by the paleontologist Dale Russell speculating about how this dinosaur might have evolved if it weren’t for the K-T extinction event.
