An international team of paleontologists, behavioral scientists, and neurologists re-examined brain size and structure in dinosaurs, concluding that they behaved more like crocodiles and lizards than mammals. This finding contradicts earlier research suggesting that dinosaurs, such as the T. Rex, had cognitive abilities similar to monkeys.
Brain Organization and Cognitive Abilities
Brain organization, not just size, plays a crucial role. In the case of dinosaurs, their brain organization is less compact than that of mammals, making it difficult for them to evolve cognitive abilities comparable to ours.
