Archaeological site types, and assemblage size and diversity in Aotearoa New Zealand

Abstract

AbstractArchaeological settlement models involve the identification of functional site types like base camps and extraction sites based, in part, on differences in the range and frequency of artefact types and fauna. Using reports describing such assemblages from Aotearoa (New Zealand) archaeological sites dating to the first 300 years after initial colonisation, differences in assemblage composition are assessed against total assemblage size. Aotearoa provides a particularly useful test case for the archaeological identification of site types since human colonisation was relatively late in world human history meaning that assemblage accumulation should show functional site types like those identified in the ethnographic record. To test this, SHE (Richness, Heterogeneity, Evenness) diversity analysis is used to examine 18 artefact and ten faunal assemblages dated pre‐1500 CE from a variety of Aotearoa locations. Results suggest artefact and faunal diversity measures perform poorly when employed to differentiate functional site types, suggesting that the null hypothesis of assemblage size dependency cannot be rejected. This result allows for comment on the appropriateness of ethnographically derived functional site types for the study of the archaeological record even when this record accumulated over short time periods.
