Scientists Recreate Largest Dinosaur Brain Using Fossils, Here’s The Goal

In findings to be published in the Journal of Anatomy, the researchers found that spinosaurus’ olfactory bulbs – which process smells – were not particularly developed, while their ears were likely attuned to low-frequency sounds.

The scientists found that the brain regions that kept the head steady and gazed upon prey were probably less developed than those of the more specialized spinosaurs.

“Despite their unusual ecology, it appears that the brain and senses of these early spinosaurs retained many aspects in common with other large-bodied theropods – there is no evidence that their semi-aquatic lifestyle was reflected in the way their brains were organized,” explained student Chris Barker. PhD in Southampton, who led the research.

“Since the skulls of all spinosaurs were highly specialized for fishing, it was surprising to see such an ‘unspecialized’ brain,” explained lead author Dr Darren Naish.

“But the results are still significant. It’s very exciting to get so much information about sensory abilities – about hearing, smell, balance, and so on – from British dinosaurs. Using the latest technology, we’re getting basically all the brain-related information we can from fossils.” – this fossil,” he continued.
