Pristerodon is an extinct genusofdicynodont therapsid from the Late Permian of South Africa, Zambia and India.

Paleobiology[edit]

Brain and senses[edit]

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 an eardrum on its lower jaw with the implication that it was hearing impaired during the act of chewing. The specimen had a 3mm cavity for cochlea which transformed sound frequency ranges into nerve impulses sent on to the brain.

Ecology[edit]

Pristerodon has been found in the Kundaram Formation of India, Usili FormationofTanzania, the Upper Madumabisa Mudstone Formation of Zambia, and the Teekloof Formation and Abrahamskraal Formation of South Africa.
