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 ...

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!

They estimated the number of neurons, or nerve cells, in the T. rex brain using their new brain volume estimates. They found T. rex had between 250 million and 1.7 billion neurons, ...

“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 ...

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 ...

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 ...

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 .

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.

T-Rex may not have big brain energy — but it might have been smarter than previously thought. For decades we've thought of the Tyrannosaurus Rex as enormous and terrifying though not ...

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.
