Abstract

Archaeologists routinely reconstruct the types of marine environments fished by past human societies in order to understand economic systems, foraging behaviour, maritime technology and seafaring abilities. These reconstructions are based on ecological data provided by archaeofish identifications, but can be problematic where coarse-grained designations, such as inshore or pelagic, are used, or the influence of fish behaviour and life history traits on movement between habitats is overlooked. In tropical waters, intra-family diversity complicates habitat reconstruction by precluding lower-level taxonomic identifications that provide precise habitat information (e.g. surge channels, dropoffs). Consequently, a single generalised habitat may be imposed on fishes that could be caught in multiple environments, thereby eroding the reliability of fishing zone reconstructions. This study employs the archaeofish assemblage from Chelechol ra Orrak (c. 3000–0 BP), Palau to examine the analytical impact of these variables on fishing habitat reconstruction based on a blind assessment of taxon-derived environmental data by two analysts. We assesses how analysts' variable decision protocols for the handling of imprecise environmental data impact resulting habitat exploitation profiles. Our results address the issue of spatial resolution in habitat information gleaned from fish assemblages like Orrak's, with important implications for the interpretation of foraging practices and maritime adaptations.
