One branch of the migrations carried pottery to the Marianas Islands at around 1500 BCE, where the earliest archaeological sites have uncovered pottery very similar to those found in the Nagsabaran Site (2000 to 1300 BCE) in Cagayan Valley in the Philippines. This indicates that the northeastern coast of Luzon is the most likely point of origin of the first open-ocean colonizing voyages into the Pacific Islands. Philippine and Marianas red-slipped pottery are both decorated with rows of stamped circles, incised patterns, and tiny delicate punch-marks. While similar red-slipped pottery also exist in the Batanes Islands and Taiwan, they lack the characteristic circle and punctate-stamped decorations. Other migrations, meanwhile, dispersed south and southwest to the rest of Island Southeast Asia. The eastward and the southward branches of the migrations converged in Island Melanesia resulting in what is now known as the Lapita culture centered around the Bismarck Archipelago.
