ESR dating of elaphurus davidianus horn fossil found in Anhui Province was reported. The sample examined by TEM electron spectrum is composed of hydroxyapatite. ESR experiments showed that the solid bone sam-pk can be chosen as dating material. According to the contents of U
Th and K in the sample determined by ICP
the annual dose of radiation was calculated using the linear uranium accumulation model and disequilibrium decay. The age of this fossil was determined to be 2.5 × 104 years.
