There are many other Old Stone Age sites in the country – in fact there are more than a hundred of these on official record as of this writing – between the time of the Cagayan Valley and the Guri Cave which already showed signs of changes toward another culture stage. One such ancient site was that of Cabatuan in the island of Panay where again fossil molars of the extinct elephas were found in a place where many flake tools also emerged.

      The work in Cagayan Valley continued also on the eastern side of the valley in the municipality of Penablanca where a huge outcropping of limestone was found. Here many caves were found to contain prehistoric materials. Among the more important of these was the Laurente Cave. In the second layer of the cave floor were flaked stone tools, waste flakes, burned and unburnt bone fragments and shells.

      The date obtained from the charcoal materials was about 16,000 years B.C. The most important find here is the proof of the earliest use of fire in Northern Luzon. Another early site in this region is that of Musang Cave which again contained flake tools, shells and animal bones, all of which were dated to about 11,000 years B.C. Other Old Stone Age sites have been uncovered in the Philippines showing that early in time, the islands were already peopled. In Central Philippines, an archeological site in Samar with small stone flake and bone tools was dated to 10,000 years. Farther south, in the island of Sanga-sanga where there was apparently scarce stone materials, the shell of the giant clam was used to form flake tools which have been dated to about 6,000 years old. This tool tradition continued in use even in later times and have been found together with pottery, polished stone adzes and other later materials in many other archeological sites.

      At about this time between 11,000 to 7,000 years or a little earlier, the level of the sea reached the present stage, and new and different culture traits began to appear, showing changes in the life of the people.
