Dento-gnathic specimens of Propotamochoerus (Mammalia, Artiodactyla, Suidae) were discovered from the upper Miocene and lower Pliocene of the Irrawaddy Group, central Myanmar. These specimens were identified as Propotamochoerus hysudricus and Propotamochoerus sp. cf. P. hysudricus. The discovery of P. cf. hysudricus from the lower Pliocene indicates a younger stratigraphic position of this genus. Small size of the premolars in the lower Pliocene specimens possibly suggests an intermediate stage of dental evolution for this form
