The only island which can match the meaning of the word Pulotu, and where most archaeological discoveries for the so called Lapita civilisations, with the reconstructed woman's face, plus the 6500yrs petroglyphed stone encrypted with concentric circles were found, was in Moturiki, Lomaiviti.
During the BC Lapita era, when looking at Fiji islands, only Moturiki in Lomaiviti has archaeological evidence that matches the meaning of Pulotu and contains discoveries like a reconstructed woman's face on stone carvings with concentric circles.
