Brain affair is about the consistence of cream cheese . In fact , for humans , this gloop for a think - organ can evencollapse under its own weight , so how can we ever desire to learn anything about the wit of longsighted - out species ? Well , a team of UK and US scientists recently demonstrated how , as they used computed tomography ( CT ) rake to recreate the brains and associated soft tissues of two spinosaur specimens long after they had rotted away .
The finding follow two British fossils ' sojourn to the EvoPalaeo Lab and the μ - Vis ecstasy - shaft of light Imaging Centre at the University of Southampton . Here , the specimens – Baryonyxfrom Surrey andCeratosuchopsfrom the Isle of Wight – were scanned by some of the most powerful CT scanners in the UK . They revealed a detailed look at the encephalon cases of these dinosaur , and by put to work backwards the team could patch together a model of how their brains would ’ve looked .
Spinosaurs are considered to have had quite an strange ecology , as fishing dinosaur that wereaquatic to some degree(though this has been the subject ofa lot of debate ) . As such , you might expect the brains to have evolved specialiser features that lend themselves to such an uttermost lifestyle , but this was n’t what the research worker found .

“ Despite their strange bionomics , it seems the brains and senses of these early spinosaurs hold many aspects in common with other big - bodied theropods , ” said University of Southampton Ph.D. student Chris Barker , who lead the study , in astatement . “ There is no grounds that their semi - aquatic lifestyles are ponder in the fashion their genius are organised . ”
The digitally redo learning ability show evidence of a hearing organization that was better suited to humble frequency sound , and slightly underdeveloped olfactory bulbs that are responsible for for detecting tone . However , there was little to write home about in terms of adaptations specific to semi - aquatic life , but it ’s potential that ’s simply because growing the right shaped snout was enough for them to thrive in this habitat .
“ Because the skull of all spinosaurs are so specialised for fish - catch , it ’s surprising to see such ‘ non - specialised ’ brains , ” summate contributing author Dr Darren Naish . “ But the results are still significant . It ’s exciting to get so much selective information on receptive ability – on auditory sense , gumption of olfaction , Libra the Balance and so on – from British dinosaur . Using cutting - edged technology , we basically obtained all the genius - related information we possibly could from these fossils . ”
The findings are another instance of how fossilology can begin to close gaps in our noesis of extinct species by recreating subdued tissues from fossilized remains , as well as highlight the value of British fossils in inquiry . Such reconstructions can arguably only tell us part of the floor , since not all brains are build the same , and the researcher say it ’s potential that their approach was only capable to identify the crying flesh of the learning ability , but not the fine details that might lend themselves to life in the water .
exchangeable questions were raised earlier this yr by a newspaper that suggested dinosaurs may have had similarly tightly - packed brains to modern birds , possibly afford them thecognitive capability of a baboon . Others argued that this bracketing may have overlooked variation in brain anatomy , but perhaps that raptorial bird really was a “ cagey fille ” after all .
The work is published in theJournal Of Anatomy .
