Paleobiology[]
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[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[]
Pristerodon has been found in the Kundaram Formation of India, the of Zambia, and the Teekloof Formation of South Africa.
