Iron Age culture of coastal central and southern Vietnam, marked by distinctive jar burials and lingling-o ear ornaments, generally seen as ancestral to the later Cham (Austronesian) people and the kingdom of Champa.
Gradually transitioned into the early historic Cham cultural sphere by around 200 AD as the Sa Huỳnh network gave rise to the coastal polities that would coalesce into Champa (already a separate, later dataset record).
