Detailed explanation-1: -rex, with its brain weighing one-third of 1 kilogram, had an estimated 3.3 billion cortical neurons-a higher density than baboons, Herculano-Houzel reports. “I have a whole newfound respect for T. rex, ‘’ she says.
Detailed explanation-2: -The largest tyrannosaurs like T. rex had an EQ in the range of 2.0 to 2.4. By comparison, our EQ is about 7.5, dolphins come in around 4.0 to 4.5, chimps at about 2.2 to 2.5, dogs and cats are in the 1.0 to 1.2 range, and mice and rats languish around 0.5.
Detailed explanation-3: -It is often said that Stegosaurus had a brain the size of a walnut-in fact it was more like the size of a lime, or a dog’s brain, but still relatively small for a dinosaur that grew up to nine metres long.
Detailed explanation-4: -In her study, Herculano-Houzel estimated that T. rex had roughly 3 billion cerebral neurons packed into its 343-gram brain-higher than the number found in baboons!
