The statue was found in a bush at Kranthi village earlier this week during a field study undertaken by the members of Association of Archaeologists here.
The statue of Buddha, in meditative posture, is 32 inches tall and 22 inches broad. The face portion had sustained damage, Association Secretary Ramachandran told PTI today.
Dr B Jambulingam of Kumbakonam, a renowned historian, said the statue contained all the features of the Buddha statues of the later Chola period like broad shoulders, long ears, slender fingers and curly hair.
Over 64 Buddha statues had been unearthed in the past from the erstwhile Chola country comprising the present day Thanjavur, Nagapattinam, Tiruvaur, Tiruchirappalli and Karur districts, he said.
The district administration had been informed about the statue and it would arrange for detailed archeological examination, Ramachandran said.
