Human occupations of caves of the Rove peninsula, southwest Viti Levu island, Fiji

Geoarchaeological investigations of limestone caves along the Rove Peninsula, where several Lapita-era (1150-750 BC) sites dating from the earliest period of Fiji's human history have been found, was undertaken by a team from the University of the South Pacific and the Fiji Museum. Surface collection and excavation in the largest cave – Qaranibourewa – was hindered by large amounts of ceiling collapse and no trace of human occupation earlier than about AD 1000 was found. The second-largest cave – Qaramatatolu – had a cave fill 190 cm thick but this was determined to be all of recent origin, having accumulated as a result of being washed down through a hole in the cave roof from a settlement above that probably existed AD 750-1250. The shell faunal remains from the Qaramatatolu excavation all suggest an open-coast location, quite different from the mangrove forest that fronts the area today. This mangrove forest probably formed only within the last few hundred years.
