Where: New Zealand (44.3° S, 176.3° W: paleocoordinates 44.3° S, 176.3° W)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Holocene (0.0 - 0.0 Ma)
• No material was dated by radiocarbon. Relative ages were inferred from species compositions. Site 1 contained six or seven species of bird not recorded in 1871-72, whereas Site 2 contained only two species not recorded then. Most of Site 1 is probably older than Site 2; both probably include material older than 1871. In the absence of absolute dates, the total times of deposition in the two sites must remain conjectural. However, it is likely that much of Site 2 was deposited in the late 1800s, after about 1865, whereas most of Site 1 was deposited before the mid 1800s. Hence, much of the material at Site 1 may be considerably older than that at Site 2, and may have been deposited before human settlement of the Chathams.
• bed-level stratigraphic resolution
Environment/lithology: loess; siliciclastic sediments
Size class: macrofossils
• At least part of Site 2 may be a human food midden, because some bird bones - mainly from large species - had been burnt. The nails, china, and glass at Site 2 suggest that there could have been a European-era dwelling there.
