Pristerodon is an extinctgenus ofdicynodonttherapsid from the Late Permian of South Africa, Zambia and India.

Pristerodon were among the earliest land animals able to hear airborne sound as opposed to hearing via ground vibrations. A South African specimen studied with neutron tomography^[1] has shown evidence of aneardrum on its lower jaw with the implication that it was hearing impaired during the act of chewing. The specimen had a 3mm cavity forcochlea which transformed sound frequency ranges into nerve impulses sent on to the brain.

Pristerodon has been found in theKundaram Formation of India,Usili Formation ofTanzania, theUpper Madumabisa Mudstone Formation of Zambia, and theTeekloof Formation andAbrahamskraal Formation of South Africa.
