Late Holocene Artifact Patterns and the Introduction of Herding to Semi-Arid Coastal Namaqualand, South Africa

Considerable change occurred in the Late Holocene Later Stone Age of Namaqualand, northwestern South Africa. Focusing on stone artifacts, pottery, and ostrich eggshell beads, the cultural sequence for the area is described. Two additions are identified, complicating the traditional model for the introduction of herding into the country. From the mid-Holocene onward, lithic assemblages are based on milky and/or clear quartz and cryptocrystalline silica and initially contain many backed tools with scrapers more common during the first millennium BC. These are hunter-gatherer assemblages. During the final centuries BC, backed bladelet-rich assemblages based on clear quartz appear, with the earliest examples demonstrating typological continuity with the existing assemblages. About 1,500years ago, expedient assemblages lacking retouch and based on poorer quality quartz appear. The three types co-occur during the last 1,500years, occasionally in combination with one another. This contrasts strongly with other parts of South Africa where just two distinct assemblage types are identified, suggesting that the hunter-gatherer-herder dichotomy is not universally valid. The artifact patterns between about 200 cal BC and cal AD 500 and the introduction of livestock suggest considerable cultural and social change, heralding the onset of a local Neolithic, but the exact mechanisms remain unclear.
