JAYAPURA, INDONESIA—Rare, prehistoric bracelets made of coral have been discovered in Puay Village on the island of New Guinea. “Most of the coral sea bracelets found in the hill slopes have been eroded by the water flowing in Lake Sentani,” archaeologist Hari Suroto told Antara News. “This kind of coral can be found in the coasts of the Pacific Ocean. The bracelets are white, and their shapes are good and smooth,” he added. The bracelets indicate that the people living near Lake Sentani had contact with people living on the coast, probably by traveling on the Jaifuri River.
