Country Papua New Guinea
Region Far Western Lapita Province, Bismarck Archipelago, New Ireland Islands, Anir Group (Feni Islands).
Brief Description The site of Kamgot (ERA) is located upon an area of raised limestone on the western end of the Island of Babase in the Anir Group (formerly known as the Feni Islands), Bismarck Archipelago, Papua New Guinea (Summerhayes 2000: Fig. 2, 171). The site is located near to the modern village of Kamgot and extends for over 400 meters east to west and 60 meters north-south; it is approximately 114 meters south of the high tide mark (Summerhayes 2000: 171, 2004: 146).

ERA was excavated between 1997 and 2000 under the direction of G.R. Summerhayes (Summerhayes 2001: 171, 2004: 146).

Site Information
Distribution of Remain(s) Between 1997 and 2000 twenty test pits were excavated within the site (Summerhayes 2001: 171, 2004: 146). However, due to a lack of published information with regards to test pits 18-20, the discussion conducted here only utilizes information relating to test pits 17-20 and therefore is only provisional.

Summerhayes (2000: 171) notes that cultural material is primarily found in an orange / brown sand layer which overlies a white beach sand. This layer becomes thinner when moving from west to east. Therefore, the deepest deposits (ranging from 1.4-1.6 meters) are found in the western portion of the site, where test pits 1, 2 and 17 are located (Summerhayes 2000: 171). Importantly, material culture densities directly correlate with the width of this cultural layer; therefore the highest densities of material culture are primarily concentrated in the western portion of the site (Summerhayes 2001: 171).

C14Date(s) Conventional (uncalibrated) radiocarbon dates and sample provenance information:

3350±45 BP (WK-7562), Test pit 1, spit 9 – Shell (Summerhayes 2001b: 33).

3260±45 BP (WK-7560), Test pit 1, spit 6 – Shell (Summerhayes 2001b: 33).

3075±45 BP (WK-7563), Test pit 1, spit 9 – Charcoal (Summerhayes 2001b: 33).

3035±45 BP (WK-7561), Test pit 1, spit 6 – Charcoal (Summerhayes 2001b: 33).

2765±50 BP (WK-7564), Test pit 1, spit 11 – Charcoal (Summerhayes 2001b: 33).

Summary of calibrated radiocarbon dates:
The calibrated radiocarbon dates for ERA all returned similar radiocarbon ages. The three oldest dates, by a very small margin, are WK-7561, WK-7563 and WK-7562, which date to 3,360 (3,250) 3,080 cal BP, 3,380 (3,290) 3,080 cal BP and 3,330 (3,210) 3,070 cal BP, respectively, at two standard deviations (95.4% probability) (Summerhayes 2004: 146). WK-7560 is marginally younger than those above, dating to 3,210 (3,080) 2,950 cal BP, whilst WK-7564 was the youngest dating to 2960 (2850) 2760 cal BP (95.4% probability) (Summerhayes 2001b: 33, 2004: 146).

Summerhayes (2004: 146) argues that the sequence of occupation at ERA dates between 3,300 and 3,000 cal B.P, at two standard deviations.
Artifact Type(s) Pottery, lithics, (flakes, adzes, ovens stones), worked shell (shell ring fragments, fishhooks, adzes, pendants, beads), worked bone (drilled dogs teeth, engraved bone), worked coral (pendant, file) and faunal remains (Summerhayes 2000: 171).

Cultural information
Significance The site of Kamgot (ERA) has been securely identified as an “Early” or “Far-Western” Lapita assemblage and thus is one of a very limited number of sites that has the capacity to provide information upon the beginnings of Lapita and its initial appearance in the Western Pacific (Summerhayes 2000: 171; 2004: 146).

The large and diverse assemblage from the site has provided a substantial amount of information with regards to the Early / Far-Western Lapita period, especially with regards to ceramics and obsidian (see Summerhayes 2000; 2001; 2004).

Finally, the site is the oldest of four Lapita sites located in close proximity to each other, within the Anir Island Group (the three other sites being Malekolon (EAQ), Balbalankin (ERC) and Feni Mission (ERG)), and thus represents the beginning of a substantial Lapita occupation in the area (Summerhayes 2000:169-172; 2004: 146-147).
Brief Research History 1997-2000– Excavations lead by G.R. Summerhayes, spanning three field seasons, occurred between 1997 and 2000, a total of twenty test pits were excavated over this period (Summerhayes 2001: 171, 2004: 146).
