- Behind the waterfall - interdisciplinary results from holley shelter and their implications for understanding human behavioral patterns at the end of the middle stone age in Southern AfricaPublication . Bader, Gregor D.; Val, Aurore; Edwin Gevers; Rhodes, Sara E.; Stahl, Nina; Woodborne, Stephan; Will, ManuelHolley Shelter is a Middle (MSA) and Later Stone Age (LSA) site in KwaZulu-Natal, South Africa. The rock shelter is located at the intersection of three ecosystems, in a strip of the Savanna Biome between the Grassland and Indian Ocean Coastal Belt Biomes. Initial excavations in the 1950s by Gordon Cramb yielded large amounts of unifacial points and splintered pieces, as well as organic remains associated with MSA occupations. Our comparative techno-typological evaluation of this material in 2015 suggested the occupations may date to early MIS 3. We then initiated new excavations at the site using modern field methods and controlled sampling for lithic and organic material. Following the initial round of interdisciplinary analysis, we herein report the first absolute ages for Holley Shelter, a detailed technological analysis of new lithic material from the uppermost MSA layers at the site, and a preliminary study of the associated faunal remains. A set of 12 C-14 dates place these occupations within a constricted chronological period dated to similar to 36,000-34,000 cal. BP that overlaps with the so-called 'final MSA'. The hornfels-dominated lithic assemblages are characterized by diverse core technologies oriented toward the production of laminar products, which include bladelets and abundant splintered pieces. The zooarchaeological analysis documents an emphasis on open grasslands that provided the bulk of the animal prey exploited by the inhabitants of the shelter, with a preference for medium-sized antelopes. Three bone retouchers, a rare occurrence in southern African MSA contexts, were identified in the faunal assemblage. The archaeological deposits at Holley Shelter reflect short-term, potentially seasonal, and specialized occupations that could be influenced by its ecological position. The archaeological material exhibits marked discrepancies with other well-dated final MSA assemblages such as those from Sibhudu, Umbeli Belli, Sibebe and Border Cave. This illustrates considerable variability and a complex spatio-temporal patterning of behavioral adaptations and cultural traditions at the end of the MSA in southern Africa.
- Geological and archeological insight into site formation processes and acheulean occupation at wonderwerk cave, northern cape province, South AfricaPublication . Goldberg, Paul; Rhodes, Sara E.; Chazan, MichaelWonderwerk Cave, located in the Northern Cape Province of South Africa, is a rare cave site with a sequence of Acheulean occupation that is derived from activity within the cave rather than via avens. Building on previous publication of the sedimentary context for the Acheulean sequence based on the North Profile of Excavation 1 at Wonderwerk Cave, we present here new observations based on micromorphological analysis of the Southern Profile of Excavation 1 and the Acheulean component of Excavation 2, along with preliminary observations on the context of artifact deposition based on renewed high-precision excavation. The results largely support earlier observations including the low density of artifacts, the aeolian contribution to the sediments, and the absence of water transport within the cave. New observations are primarily the presence of a significant component of rhizoliths in the South Profile that appear to be the result of the penetration of roots into the cave from the surface of the hill. This study adds significantly to our understanding of site formation processes and hominin activity during the Acheulean at the front of the cave. However, these remain limited windows into a much larger system that will require continued investigation.
