Abstract
New fossil dentitions of a large-sized Tetraconodon (Mammalia, Artiodactyla, Suidae) were discovered from the lower part of the Irrawaddy Formation, Migyaungye Township, Magway Division, central Myanmar. These specimens are the largest among the Tetraconodon specimens ever found in Myanmar. The molar dimensions of these specimens are similar with those of Tetraconodon magnus but are smaller in the dimensions of last two premolars than T. magnus. Therefore, we assigned these specimens as Tetraconodon sp. cf. T. magnus. The occurrence of a large Tetraconodon confirms an Upper Miocene age for the lower part of the Irrawaddy Formation.
