New Stone Age
Arku Cave, Peņablanca, Cagayan
It is a stone tool used for the preparation of bark cloth. Early man in Palawan fashioned the beaters from cylindrical stones and used the stone beaters for pounding the bark to loosen the pulp from the fiber. The bark cloth is ready when all the pulp has been stripped off, leaving a network of fibers. The stone tool found in Arku Cave, Penablanca, Cagayan was dated 1255-605 B.C. Another bark-cloth beater was found in Sagung cave in Southern Palawan.
