Fatu Aki Anik Knua is an archaeological site in the mountainous interior of Timor-Leste comprising of a limestone cave and open site locale. Excavations in 2015 yielded an extraordinary quantity of earthenware pottery with over 13,000 potsherds recovered, all dating within the last 1800 years. The Faak pottery is described and examined in the context of Timor-Leste and eastern Indonesian assemblages more widely. The intensification of ceramic technology transfers and initial pottery use, which occurred at many sites in the region during the Paleometallic era, is highlighted. The essential features of this hinterland site assemblage show affinities with Early Metal Age pottery occurring extensively throughout eastern Indonesia after 2500 BP
