       Pristerodon is a genus of dicynodont that lived during the late Permian.‭ ‬Like relative genera,‭ ‬Pristerodon was a plant eater and likely dug out burrows on flood plains.‭ ‬Analysis of one Pristerodon has revealed the presence of an eardrum in the lower jaw.‭ ‬Not only has this given us an insight into how Pristerodon sensed their environment,‭ ‬but that as Pristerodon chewed food,‭ ‬they likely had their hearing impaired and were likely more vulnerable to predators sneaking up on them as they ate.
