It's officially news: T. rex had baboon-like numbers of brain neurons, which means it had what it takes to build tools, solve problems, and live up to 40 years, enough to build a culture!

Based on CT scan reconstructions, the T. rex brain was probably “ a long tube that has very little in terms of the cortical expansion that you see in a primate or a modern bird,” said ...

“The possibility that T. rex might have been as intelligent as a baboon is fascinating and terrifying, with the potential to reinvent our view of the past,” study co-author and University of ...

According to Caspar and his colleagues, this was one of the main problems with the 2023 study: that it overestimated the brain size of T. rex by assuming the brain filled the whole endocranial cavity.

Ashley Morhardt, a paleoneurologist at Washington University School of Medicine in St. Louis, has her own concerns about the approach. Not only is it possible that the equations over- or ...

The name Tyrannosaurus rex means the “king of the tyrant lizards,” and by all accounts, that’s exactly what T. rex was. A ruthless and fearsome predator, it ruled the world in the Late Cretaceous ...

T Rex may have had brain capable of using tools and passing knowledge to kin, study claims. Paleontologists call for further studies including more data to validate the findings .

When the researchers looked at endocasts of T. rex brains – internal modeling of the cranial vault where the dinosaurs' soft tissue would have once been housed – they found that previous brain ...

A 67-million-year-old T. rex skeleton named "TRX-293 TRINITY Tyrannosaurus" is seen during a preview at Koller auction house in Zurich, Switzerland, March 29, 2023.

Like modern predators, T. rex had a proportionally large brain compared with its plant-eating quarry. This hypothesis has exciting implications for the evolution of birdsong.
