The skeletal remains of an ancient human being, believed to be inhabited Keeladi in Sivaganga district, have started surfacing at Konthagai, which is believed to be the burial site of the civilization. It is two kilometers away from Keeladi.Keeladi has revealed that an ancient civilization thrived on the banks of the Vaigai more than 2,600 years ago. It has long been believed that the habitation at Keeladi may have extended to the neighbouring areas of Konthagai, Manalur and Agaram, as ancient artefacts have also been found there.

Burial urns were discovered at Konthagai even before the excavation began at Keeladi. It is believed that Konthagai was the burial site of Keeladi, where first level and second level burials could have been conducted. Sources at the state archaeology department said that people could have either been directly buried there or those who died elsewhere could have been brought and laid to rest here in the urns.

Madurai Kamaraj University has signed an MoU with the archaeology department to conduct research on the remains, especially bones and other artefacts at the site.
