Mirror has reported that A giant dinosaur as long as a double decker had a brain just 6.3cm big.
Titanosaurs were four legged herbivores with a long tail and neck that lived over 72 million years ago.
At just 14m in length they were half the size of their distant relative the Diplodocus.
But the discovery of a rare complete skull is allowing scientists to understand how dinosaurs’ brains worked.
University of Manchester scientists have found one of the most complete sauropod dinosaur braincases ever found in Europe.
Until now, questions relating to how intellectual dinosaurs were and their sensory abilities have remained a mystery.
In a paper published in the journal PLOS ONE, the researchers describe how they used computer software to reconstruct the cavity where the brain lay in the skull.
They also created digital images of the cranial nerves as well as certain blood vessels and the labyrinth of the inner ear.
Skulls and, in particular braincases, are so fragile that they are rarely found in such good condition.
The skull was found at a dig site in eastern Spain in 2007 and experts have spent the last few years studying it to see what secrets it may reveal.
Ever since experts have dedicated hours of their time to uncovering the skull’s secrets.
After studying the find, the team concluded their brains fitted in tiny cavities of only 6.3cm.
Dr Fabien Knoll, from the University of Manchester , said: “This is such a rare finding that is why it is so exciting.
“Usually we find vertebrae or other bones, very rarely the braincase and this one is complete.
“I was present on the dig site when it was uncovered and it was a very special moment.
“Currently we know very little about the brain of dinosaurs.
“Research such as this is fundamental if we want to get an idea about the cognitive skills of these animals or if they had keen hearing or good eyesight and plenty of other information.”
Dr Knoll said: “In a few years’ time if more finds like this come to light and, above all, if they are studied with the modern imaging technologies then we could really start to understand more about dinosaur brains.”
