The King of the Dinosaurs was NOT a genius! Scientists pour cold water on theory that T.Rex was as intelligent as a monkey - and say it was 'more like a smart crocodile'

With its ruthless ability to hunt down prey, there's no denying that Tyrannosaurus rex was a clever beast. But the famous dinosaur, which died out 66 million years ago, couldn't match today's primates for intelligence, a new study shows. Researchers have poured cold water on the claim by a neuroscientist last year that T.Rex possessed'baboon-like' cognitive abilities and was capable of problem-solving. The controversial claim, immediately greeted with skepticism in the scientific community, has now been debunked. Instead, T.Rex's brain power was more like that of today's reptiles, such as crocodiles and lizards, the researchers argue.
