Surmising even the physical appearance of a dinosaur - or any extinct animal - based on its fossils is a tricky proposition, with so many uncertainties involved. Assessing a dinosaur's intelligence, considering the innumerable factors contributing to that trait,

New research is throwing some cold water on the idea that the fearsome Tyrannosaurus rex was as smart as a primate. These possibly scaly-lipped theropods were about as smart as living reptiles like crocodiles, but not quite as intelligent as monkeys. The findings are detailed in a study published April 26 in the journal The Anatomical Record

While we don't like to talk ill of the dead, new physiological analysis has found that the king of the dinosaurs was not so smart after all. It upends previous research that last year likened the brain and neuronal composition of the Tyrannosaurus rex to that of a primate.

How intelligent was Tyrannosaurus rex? Paleontologists and other researchers have long been intrigued by this question—and it’s a difficult one to answer. While scientists have plenty of fossilized bones to study,

Dinosaurs were as smart as reptiles but not as intelligent as monkeys, as former research suggests. An international team of paleontologists, behavioral scientists and neurologists have re-examined brain size and structure in dinosaurs and concluded they behaved more like crocodiles and lizards.

A new study challenges findings of Tyrannosaurus Rex intelligence from 2023 and claims the T. rex may not have been that smart.
