The two fossils are the first ever hominin fossils from submerged Sundaland and demonstrate that Homo erectus populations extended beyond Java onto the exposed lowland plains during the Middle Pleistocene.

It is likely that other hominin populations migrated south in a similar manner; however, limited fossil evidence complicates the understanding of the evolution and migration of these species. It is likely that more fossils are to be found on the submerged Sundaland seabed.
