The Emo site (OAC), Gulf Province, Papua New Guinea: Resolving long-standing questions of antiquity and implications for the history of the ancestral Hiri maritime trade

Abstract Since the 1970s the site of Emo (aka ‘Samoa’, ‘OAC’) in the Gulf Province of Papua New Guinea has been cited as one of the earliest-known ceramic sites from the southern Papuan lowlands. This site has long been seen as holding c.2000 year old evidence of post-Lapita long-distance maritime trade from (Austronesian-speaking) Motu homelands in the Central Province, where pottery was manufactured, to the (non-Austronesian) Gulf Province some 400km to the west where pottery was received and for which large quantities of sago were exchanged (the ancestral hiri trade). However, until now the only three radiocarbon dates available for Emo were out of chronostratigraphic sequence, and few details on the site had been published. This paper presents the results of new excavations and the first detailed series of AMS radiocarbon determinations from Emo, thereby resolving long-standing uncertainties about the age of the site and its implications for the antiquity of the long-distance Motuan hiri maritime trade.

The Mine Island Aboriginal stone arrangements: spiritual responses to late Holocene change on the central Queensland coast

Abstract The Mine Island stone arrangement complex is a large ceremonial complex on the central Queensland coast. The arrangements are in excess of 2 km of looping and U-shaped aligned stones. A series of middens, directly adjacent to the stone arrangements, was recently excavated, providing potential chronological insights into the construction and ceremonial use of the stone arrangement. We posit that these stone arrangements represent a shared spirituality linking coastal peoples for over 300 km of coastline, the inception of which was possibly linked to a range of broader changes impacting coastal hunter-gatherers on the central Queensland coast after around 500 BP.
