A series of caves in eastern Sabah, northern Borneo, Malaysia, which form a large complex like those of Niah, Sarawak. The largest cave is Agop Atas, and it has produced an industry of early Australian type dated to 8000 years ago, with a pottery sequence dated from 500 BC to the present. It, along with Agop Sarapad, were inhabited from c 9000-5000 BC by hunters using pebble and flake tools. After a 4000-year gap, the caves were reused between c 2000-500 BC by people using stone flake tools and pottery. The caves were abandoned again and later reused in the early 1st millennium AD.
