First research was carried out by Prussian prehistorians at the beginning of the 20th century and later by Russian and Polish archaeologists.

Bayesian Modeling and Chronological Precision for Polynesian Settlement of Tonga

Despite a rather long history of research, many questions about the ZC phenomenon still remain. Geochronometria 44, 1; In that varied nomenclature at least one is certain: Still an important question is: Should it be brought together with a wider cultural complex of East European roots or excluded from the mosaic of the Baltic Subneolithic?

This is linked with the origin of pottery making in the area under study as well as the beginning of the ZC. In the literature there are a few theories which involve different subneolithic or neolithic cultures in that process for example: There are opposing opinions about the end of the ZC tradition.

Others see it more briefly Kukawka, There is a lack of strong premises in archaeological assemblages to support or to prove the falsity of both hypotheses. Recently applied chronometric hygiene protocols excluding radiocarbon dates on wood charcoal without species identification all but eliminates this chronology as it has been built for the Kingdom of Tonga, the initial islands to be settled in Polynesia.

They further illustrate an exceptionally short duration for the initial colonizing Lapita phase and a somewhat abrupt transition to ancestral Polynesian society as it is currently defined.

Absolute chronology of the Zedmar culture: Re-thinking radiocarbon dates : Geochronometria

Providing absolute dates for a wide range of material, it underlies the establishment of refined archaeological chronologies throughout the world. Over the past 65 years, there have been many advances in measurement techniques, in our abilities to calibrate radiocarbon years into calendar years, in the protocols accepted for sample selection, and in understanding more fully the relationship between chronometric dates and archaeological events of interest [ 1 ], [ 2 ].

At least a few can be called revolutionary, as they have reset chronological knowledge with substantive consequence. One of these revolutions currently is underway in Polynesia, where prehistory is of short duration and, by world standards, relatively recent. Consequently there is increasing concern for chronological accuracy and precision through exclusive dating of short-lived samples from well-defined archaeological contexts. The consequences are most apparent for East Polynesia, resulting in substantially shortened sequences for human presence and subsequent cultural development [ 3 — 6 ].

Elsewhere, to the west, island chronologies are also being questioned because they largely are built on unidentified wood charcoal samples with possibilities for inbuilt age, or shell dates where marine reservoir offsets and related issues are unresolved. A complete reevaluation of the entire chronology for Oceanic settlement has been advocated [ 7 ].

Bayesian Modeling and Chronological Precision for Polynesian Settlement of Tonga

Tonga is positioned on the western flank of the Polynesian triangle, and it was the first island group to be settled in Polynesia [ 8 ]. A similarly precise chronology for Polynesian expansion and associated events throughout Tonga has yet to be addressed. This is equally critical for it is here that ancestral Polynesian society emerges [ 10 ].
