Puthupattan (56) was digging his field with an earthmover when the machine suddenly hit a hard object about four feet beneath the earth. The farmer and other locals dug up the pit and found the Lingam, local revenue officials said.
He immediately informed the nearby revenue office and a team of officials rushed to the site, they said.
The officials said a preliminary study indicated that the lingam was more than 300 years old. However the exact period to which it belonged could be ascertained only after inspection by experts from Archaeological Survey of India on November 7, they said.
