抄録

The carved ivory objects which might be made from mammoth tusk were measured AMS ^<14>C dating. About 1 mg of powdered sample and about 0.75 mg of demineralized sample were used for δ^<13>C and δ^<15>N measurement using ANCA-MS. The δ^<13>C values for collagen of samples (-21.2 to -20.2‰) indicate a fully dependence on C3 plants. About 7 mg of powdered sample was combusted to CO_2 and converted to graphite. The carbon isotope ratios (^<14>C/^<12>C and ^<13>C/^<12>C) were measured with an accelerator mass spectrometry (AMS) system at Nagoya University. From the measured radio carbon isotope ratios, ^<14>C ages of the mammoth ivory were calculated as 36,980±240 yr BP and 38,360±250 yr BP, with 1σ errors, and ^<14>C age of ivory appeared to be mammoth tusk were calculated as 27,010±110 yr BP and 13,155±50 yr BP, with 1σ errors, respectively. These ^<14>C ages were all belonged of the Pleistocene, consequently these objects was determined to be made from mammoth tasks.
