Data collected from the Hamersley Plateau over the last four decades are examined for patterns in the archaeological record. Data relating to the timing of the archaeological appearance of backed artefacts, seed-grinding technology and rock art are currently too few to indicate major cultural changes with certainty. Increases in numbers of radiocarbon dates from archaeological sites on the Hamersley Plateau are evident in the late Holocene. This can be interpreted as a pattern of cultural change or natural decay in datable material. I conclude that taphonomic bias is the most important variable in the distribution of the radiocarbon date sample from the Hamersley Plateau. That said, further accumulation of dates and data may show archaeological changes in the Hamersley Plateau that represent local expressions of broader trends in the Australian semi-arid and arid zones.
