Dinosaurs: Scientists have digitally rebuilt a dino brain!

Ever wanted to know what a dinosaur's brain looks like?
Well, scientists from the University of Bristol have used special technology to do just that.
They've digitally rebuilt the brain of Thecodontosaurus, better known as the Bristol dinosaur and one of the earliest dinosaurs to roam the Earth.
This "pioneering reconstruction" of the brain has revealed what this particular dinosaur might have eaten as well as its ability to move quickly.
How did scientists digitally rebuild a dinosaur's brain?
The team created 3D models of the brain from CT scans - A CT scan uses x-rays and a computer to create detailed images.
The CT scans were made by digitally removing the bone from the rock and identifying details about the dinosaur's brain and inner ear.
This information was "previously unseen in the fossil".
"Even though the actual brain is long gone, the software allows us to recreate brain and inner ear shape via the dimensions of the cavities left behind", said Antonio Ballell, lead author of the study.
What else has been found?

The researchers discovered that this dinosaur may have eaten meat, unlike its giant long-necked later relatives including the Diplodocus and Brontosaurus, which only fed on plants.
The analysis "uncovered many fascinating features, some of which were quite surprising" said Antonio Ballell.
"Whereas its later relatives moved around...on all fours, our findings suggest this species may have walked on two legs and been occasionally carnivorous," he added.
The digitally constructed brain also indicated a "control of balance and eye and neck movements, suggesting Thecodontosaurus was relatively agile and could keep a stable gaze while moving fast".
"This could also mean Thecodontosaurus could occasionally catch prey", although its tooth structure "suggests plants were the main component of its diet. It's possible it adopted omnivorous habits."
The researchers were also able to reconstruct the inner ears, to get a better idea of how well this dinosaur could hear compared to other species.
They found that its hearing frequency was "relatively high", suggesting "some sort of social complexity" and "an ability to recognise varied squeaks and honks from different animals."
