Brain and senses 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 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 Pristerodon has been found in the
Kundaram Formation of India,
Usili Formation of
Tanzania, the
Upper Madumabisa Mudstone Formation of Zambia, and the
Teekloof Formation and
