Abstract Decisions related to the production of lithic technology involve landscape-scale patterns of resource acquisition and transport that are not observable in assemblages from any one single site. In this study, we describe the stone artifacts from a discrete cluster of stone artifacts assigned to the Robberg technocomplex (22-16 ka) at the open-air locality of Uitspankraal 9 (UPK9), which is located near two major sources of toolstone in the Doring River catchment of Western Cape, South Africa.OSLdating of the underlying sediment unit provides aterminus post quemage of 27.5 ± 2.1 ka for the assemblage. Comparison of near-source artifact reduction atUPK9 with data from three rock shelter assemblages within the Doring watershed – Putslaagte 8 (PL8), Klipfonteinrand Rock Shelter (KFR), and Mertenhof Rock Shelter (MRS) – suggests that “gearing-up” with cores and blanks occurred along the river in anticipation of transport into the wider catchment area. The results reveal an integrated system of technological supply in which raw materials from different sources were acquired, reduced, and transported in different ways throughout the Doring River region. 

Modern Homo sapiens engage in substantial ecosystem modification, but it is difficult to detect the origins or early consequences of these behaviors. Archaeological, geochronological, geomorphological, and paleoenvironmental data from northern Malawi document a changing relationship between forager presence, ecosystem organization, and alluvial fan formation in the Late Pleistocene. Dense concentrations of Middle Stone Age artifacts and alluvial fan systems formed after ca. 92 thousand years ago, within a paleoecological context with no analog in the preceding half-million-year record. Archaeological data and principal coordinates analysis indicate that early anthropogenic fire relaxed seasonal constraints on ignitions, influencing vegetation composition and erosion. This operated in tandem with climate-driven changes in precipitation to culminate in an ecological transition to an early, pre-agricultural anthropogenic landscape. 

Southern Africa presents the best-documented Middle and Later Stone Age (MSA and LSA) records in Africa, and yet signi cant uncertainties still exist concerning the sequence and timing of behavioral and occupational changes in the region. A recent surge in research has provided a suite of new results that indicate more intricate and complex pa erns than those previously considered. This paper describes recent excavations at the archaeological site of Varsche Rivier (VR) 003 located in the poorly-researched southern Namaqualand (Knersvlakte) region of South Africa (Western Cape Province). Two seasons of excavations have revealed a long sequence of MSA and LSA cultural materials, including lithics, fauna, ostrich eggshell, marine mollusks, beads, and pigments; bedrock has yet to be reached anywhere in our excavations. Within the shelter, we have uncovered probable Howiesons Poort material, with overlying late MSA and capped by late Holocene LSA. On the slope, the deepest materials are earlier MSA, overlain by assemblages with a nities to the Still Bay and Howiesons Poort. In addition to provid- ing descriptions of the lithic, faunal, and pigment assemblages, we report on the results of micromorphological analysis of the sediments and optically stimulated luminescence (OSL) and radiocarbon dating of the sequence. Based on the analysis of single-grain samples from both parts of the excavation, OSL age estimates suggest that the putative Howiesons Poort assemblages at VR003 were deposited 45.7–41.7 kya. While our results are stratigraphi- cally consistent, they are substantially younger than any previously published Howiesons Poort chronologies. We discuss the implications of these results in detail. When presenting the results of our analyses, we compare the VR003 assemblages to those from other sites in the region to address questions concerning lithic technology, stone material exploitation, chronology, ecology, and the signi cance of “complex” behaviors, such as early bead production and long distance transport of marine mollusks.
