The Austronesian Engraving Style (AES), consisting of petroglyphs carved into rock surfaces, is far less common than APT. The majority of these sites are in coastal New Guinea, and Island Melanesia. AES sites, which can be tentatively traced back to the similar Wanshan petroglyphs of Taiwan, are believed to be largely correlated to the prehistoric extent of the Lapita culture. The common motif of this tradition is curvilinear geometric engravings like spirals, concentric circles, and face-like forms. These resemble the geometric motifs in APT, though they are considered to be two separate artistic traditions. AES is particularly dominant in the Solomon Islands and New Caledonia, where engravings are far more abundant than painted sites.
