Speicies Identification and Dating for Wooden Warehouse Excavated at Baengnyeongsanseong in Geumsan, Korea

This study aimed for species identification and tree-ring dating and radiocarbon dating of wooden warehous materials excavated from Baengnyeongsanseong in Geumsan. The species of 83 wooden materials were identified as 38 Platycarya spp., 34 Cerris Section, 8 Prinus section, 2 Hard pine, and 1 Kalopanax pictus. After cross-dating of 5 Cerris Section samples with the TSAP program, one Cerris Section chronology (GSQU 1S) was constructed. To identify the exact date, one material which show many tree-ring (GSQU 05) was analyzed by radiocarbon dating using wiggle match. As a result of radiocarbon dating, the outermost edge of east beam (GSQU 05) was found to be A.D. 575-655 or A.D. 665-685. The radiocarbon dating of wooden warehouse material was consistent with the archaeologically estimated date.
