NAKHON RATCHASIMA: The Department of Fine Arts is examining newly discovered prehistoric artefacts initially believed to be from 2,500-3,000 years ago.
The seven shaped stone axe blades and some earthenware were found on Friday by a villager at a cassava plantation in Ban Taling Chan in Khon Buri district.
Sompong Sarawan said he discovered them about 30 centimetres under the surface after the top soil was swept away by run-off triggered by rain.
Officials from the Phimai national museum were called to examine the site and initially concluded the axe blades were 2,500-3,000 years old.
The age of the pottery had not been verified, said Artidhaya Tirachote, the official archaeologist at Phimai national museum.
All of the artefacts had been handed over to the museum for public display, and other experts were expected to be called in to examine them further, she said.
