JAYAPURA, INDONESIA—Pottery, fresh-water mollusk shells, marine mollusk shells, and animal bones have been discovered in Rukhabulu Awabu, Ifeli-feli, and Ceruk Reugable caves near Lake Sentani. Hari Suroto of the Jayapura Archaeology Office told Antara News the evidence suggests that Neolithic people living in the caves had contact with coastal areas, where they would have obtained the marine mollusks. The pottery was also likely to have been imported. “The black color found outside the potteries indicated that they were also used to cook,” he added.
