Ancient genius. Scientists Say Tyrannosaurs Are Much Smarter Than You Think

Often tyrannosaurs are presented as ruthless hunters who bow to their instincts, but this image may need revision.

According to the study, tyrannosaurs had the same number of brain neurons as modern primates and might have been capable of problem-solving and even culturing, according to the Daily Mail.

Dinosaurs ruled the earth for about 179 million years before suddenly disappearing during the Cretaceous-Paleogene extinction about 66 million years ago.

Prior to this, some species had developed bird-like features such as feathers, wings, claws, and an enlarged skull. It was a gradual process that began 100 million years ago and took tens of millions of years.

Because dinosaur soft tissue is not usually found in fossils, little is known about their brains, but given their association with birds, information about them can be gleaned from the brains of modern emus and ostriches.

Dr. Susanna Erculano-Huzel, in her study published in The Journal Of Comparative Neurology, aimed to reveal the cognitive abilities of dinosaurs such as tyrannosaurs by examining the brains of modern sauropsids (birds, turtles, and scales).

Recent research has shown that birds are intelligent despite their small heads. For example, Eurasian jays can resist the temptation to get better rewards, and crows are as smart as a seven-year-old.

Birds have been found to have more neurons per gram of brain than mammals and primates, which helps them solve problems.

Dr. Using computed tomography, Erculano-Huzel studied the fossilized skulls of theropods, a group of bipedal dinosaurs that includes tyanosaurus and modern-day sauropsids.

He concluded that dinosaurs would have had the same brain mass as birds of the same size, which can be traced back to pre-asteroid times.

Therefore, a neuroscientist might enlarge the brain of an ostrich, ostrich, or chicken, as long as they are proportional, to envision the brain of a tyrannosaurus rex.

He then calculated how many neurons a theropod would have using the known number and brain mass for a sauropsid.

Their findings suggest that Tyrannosaurus had a brain mass of 343 grams and 3,289 million telencephalic neurons, not far from the 2,875,000,000 found in baboons.

A separate study using a mathematical equation showed that the number of neurons in warm-blooded animals correlated with their lifespan.

Using this equation, he suggests that a Tyrannosaurus rex may have lived between 42 and 49 years old, despite the fact that the oldest known specimen lived to be 28 years old.

In his work, he writes: “An elephant-sized but agile bipedal predator must have been a highly skilled hunter with the intelligence of a macaque or baboon.

“Current findings suggest that theropod dinosaurs, such as tyrannosaurs, which have even more telencephalic neurons than modern hookups, had the biological ability to use and manufacture tools and develop cultures similar to modern birds and primates.”
