This study was carried out to identify the species of wooden coffins excavated from ancient kings' tombs of Nakrang and Pro-Three-Kingdoms to the beginning period of the Three Kingdoms, and the private tombs of the middle stage at the Yi dynasty. The species of wooden coffins were identified as three softwoods(Thxus cuspidata, Sciodopitys verticillata, Pinus densiflora) and six hardswoods(Quercus acutissima, Quercus serrata, Zelkova serrata, Platycarya strobilarea, Alnus japonica and Morns spp.). Thxus cuspidata, wooden coffins of Nakrang kings' tombs, is distributed through Korea. However in previous examination it was known as Cunninghania lanceolata, native species in south China. Sciodopitys verticillata used as a wooden coffin of King Muryung's tomb was native to Japan. It was a material evidence proving the cultural exchange between Paekche Kingdoms and Japan in those days. Pinus densiflora was the species of wooden coffins excavated from private tombs in Yi dynasty, which was not found out from Pro-Three-Kingdoms and Three-Kingdoms. Quercus accutissima was used for making a trough shape wooden coffins at Daho-ri ancient tombs and Quercus serrata was used a outer wooden coffin of Nakrang kings' tombs. An adamant iron mongery might be used to manufacturing a trough shape wooden coffin. This indicates that a developed iron-manufacturing technics existed in Korea at that time. Zelkova serrata was used for making wooden coffins of Imdang and Kaya ancient tombs, Chunma and Hwangnam king tombs. Platycarya strobizacea was used for making wooden coffin of Daegok-ri, Alnus japonica for Daho-ri coffins and Morus spp. for Imdang coffins.
