A new study by an international team of palaeontologists, cognitive scientists and neurologists has reassessed the intelligence of Tyrannosaurus Rex, the famous carnivorous dinosaur from the Cretaceous period. Published in the journal 'The Anatomical Record', the research refutes previous hypotheses that attributed ape-like intelligence to T-Rex, based on an estimated large number of neurons in its brain. According to the new data, based on a more accurate analysis of the T-Rex's brain structure, its cognitive abilities were more similar to those of a modern-day crocodile or lizard. Despite its imposing size, its cognitive abilities were probably suited to its opportunistic predator lifestyle, which did not require complex thinking or elaborate social behaviour. They were therefore more similar to that of a crocodile.
While reassessing the intelligence of the T-Rex, the research offers interesting insights into its biology and behaviour. The results suggest that the dinosaur was endowed with good eyesight and a keen sense of smell, abilities that were essential for hunting. In addition, the complex structure of its inner ear indicates excellent hearing ability, which is useful for communication and for locating prey. The Tyrannosaurus Rex was a formidable predator, but its success was mainly due to its physical strength and keen senses, not exceptional intelligence.
