The Paleozoic rocks are well exposed in the Taungnyo area and the main purpose of classification is taxonomic status of the invertebrate fossils and describing the systematic paleontology of brachiopod fossils from Taungnyo Formation. Mainly distributed clastic sedimentary rocks of Taungnyo Formation (Early Carboniferous) and carbonate rocks of Moulmein Limestone Group (Permian to Middle Triassic) are well exposed in the Taungnyo area. In this study, mainly, a total of five species are recognized in the clastic sediments of Taungnyo Formation. Most brachiopods are generally found abundant and well preserved in the mudstone unit. Among them, most of the taxa have not been recorded previously. The brachiopods include: Fimbrispirifer venustus, Ovetensispirifer ovetensium, Aullacella sp., Kayserellae emanuelensis, and Chonopectus sp. All of the species are first recorded in Myanmar.
