So Herculano-Houzel looked at T. rex’s bony brain cases and compared them to the skeletons of its living cousins: the birds. It's officially news: T. rex had baboon-like numbers of brain neurons ...

“So whereas there is no reason to assume that T. rex had primate-like habits, it was certainly a behaviorally sophisticated animal.” Brain tissue doesn’t fossilize, and so researchers ...

rex. How Can You Measure Brain Mass? Neuronal numbers are difficult to determine without brain tissue, though they aren’t impossible to approximate in modern species, since there are scalable ...

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!

According to Ashley Morhardt, a paleoneurologist at the Washington University School of Medicine, some things are evident from fossils that might give us some clues into a dinosaur’s intelligence. For ...

A new study debunks previous findings that the dinosaur's intelligence was similar to that of primates, finding instead that they're about as smart as modern-day crocodiles. When you purchase ...

Uh, no, said Gutierrez. He writes that Herculano significantly overestimated the size of the actual brain inside T. Rex skulls, which were much more closely related to modern crocodiles than birds.

The new paper also suggests that the actual size of a T. rex brain may have been overestimated in the past. But Hady says that there's plenty of evidence to prove that the dinosaurs still had ...

The isotropic fractionator method is clever, but scientists will never have an actual T. rex brain to dissolve. Instead Herculano-Houzel relied on the scaling relation between telencephalon size ...
