CT scans of its skull and brain by Paulina-Carabajal and Louis Jacobs et al. revealed that Pawpawsaurus''' hearing was on par with that of modern crocodilians, indicating that its hearing was relatively poor. Its sense of smell meanwhile, while not as advanced as that of later ankylosaurs, was still more powerful and acute than many of the theropods existent at the time thanks to its large nasal cavities. The enlarged nasal cavities of Pawpawsaurus'' would also likely have been useful for cooling blood that was entering the brain, finding food and potential mates, or alerting it to danger.
