These adaptations helped them live a somewhat aquatic lifestyle that involved stalking riverbanks in quest of prey, among which were large fish. This way of life was very different from that of more familiar theropods, like Allosaurus and Tyrannosaurus.<\/p>\n<p>To better understand the evolution of spinosaur brains and senses, the team scanned fossils of Baryonyx from Surrey and Ceratosuchops from the Isle of Wight. These two are the oldest spinosaurs for which braincase material is known. The huge creatures would have been roaming the planet about 125 million years ago years ago. The braincases of both specimens are well preserved, and the team digitally reconstructed the internal soft tissues that had long rotted away.<\/p>\n<p>The researchers found the olfactory bulbs, which process smells, weren&#8217;t particularly developed, and the ear was probably attuned to low frequency sounds. Those parts of the brain involved in keeping the head stable and the gaze fixed on prey were possibly less developed than they were in later, more specialized spinosaurs.\n<\/p>\n<div class=\"article-gallery lightGallery\">\n<div data-thumb=\"https:\/\/scx1.b-cdn.net\/csz\/news\/tmb\/2023\/oldest-spinosaur-brain-1.jpg\" data-src=\"https:\/\/scx2.b-cdn.net\/gfx\/news\/hires\/2023\/oldest-spinosaur-brain-1.jpg\" data-sub-html=\"Three-dimensional reconstruction of the brain cavity and associated nerves and blood vessels within the braincase of the iconic british spinosaurid Baryonyx walkeri.

It&#8217;s exciting to get so much information on sensory abilities\u2014on hearing, sense of smell, balance and so on\u2014from British dinosaurs.

Ceratosuchops itself was only announced by the team in 2021, and its discovery was followed up by the publication of another new spinosaur\u2014the gigantic White Rock spinosaur\u2014in 2022. The braincase of Ceratosuchops was scanned at the \u03bc-Vis X-ray Imaging Centre at the University of Southampton, home to some of the most powerful CT scanners in the country, and a model of its brain will be on display alongside its bones at Dinosaur Isle Museum in Sandown, on the Isle of Wight.<\/p>\n<p>&#8220;This new research is just the latest in what amounts to a revolution in paleontology due to advances in CT-based imaging of fossils,&#8221; said co-author Lawrence M. Witmer, professor of anatomy at the Ohio University Heritage College of Osteopathic Medicine, who has been CT scanning dinosaurs\u2014including Baryonyx\u2014for over 25 years. &#8220;We&#8217;re now in a position to be able to assess the cognitive and sensory capabilities of extinct animals and explore how the brain evolved in behaviorally extreme dinosaurs like spinosaurs.&#8221;<\/p>\n<p>&#8220;This new study highlights the significant role British fossils have in our constantly evolving, fast-moving understanding of dinosaurs, and shows how the UK\u2014and the University of Southampton in particular\u2014is at the forefront of spinosaur research,&#8221; said Dr. Neil Gostling, who leads the University of Southampton&#8217;s EvoPalaeoLab. &#8220;Spinosaurs themselves are one of the most controversial of all dinosaur groups, and this study is a valuable addition to ongoing discussions of their biology and evolution.&#8221;<\/p>\n<div class=\"article-main__more p-4\">\n<p><strong>More information:<\/strong><br \/>\n                                                Modified skulls but conservative brains?
