Rhino Cave, located at the World Heritage site of Tsodilo Hills, is one of the three main Middle Stone Age (MSA) sites in Botswana. Initial investigations during the mid-1990s left unanswered a number of key questions regarding the early use of the cave. This prompted the current investigations, which have unearthed a wealth of MSA artifacts from a lag deposit. Results of a selectively employed chaîne opératoire analysis have revealed a very special set of behavioral patterns. It will be argued that the best-fit interpretation of the results from this investigation lies within the realm of ritualized behavior. The assemblage is characterized by an unexpectedly large number of MSA points, which are for the most part produced in non-locally acquired raw materials. These points are colorful, carefully and often elaborately made, and, once complete, never left the cave. They were either deliberately burned to the point where they could no longer be used, abandoned, or intentionally smashed. These artifacts were found together with tabular grinding slabs and pieces of the locally available pigment, specularite. This assemblage was recovered directly beneath a massive, virtually free-standing rock face that has been carved with hundreds of cupules of varying sizes and shapes. A section of the carved rock face was recovered from well within the MSA deposits in association with handheld grinding stones.
INTRODUCTIONI t has been proposed that "collective ritual -with its formal characteristic of amplified, stereotypical, redundant display -might be expected to leave a loud archaeological signature" (Watts 2009: 62). According to a number of researchers (e.g., Knight 2009;Knight 2010;Power 1999Power , 2009Power and Aiello 1997;Watts 1999Watts , 2002Watts , 2009) the archaeological record of ochre use, dating from the late Middle Pleistocene, provides such a signature. Symbolism, a crucial feature of ritual behavior, has been central to the debate on behavioral modernity. . However, one area of investigation that could potentially reveal patterns of ritual behavior has received minimal attention within African MSA studies. This is the application of the chaîne opératoire. Results from this method identify sequences of conscious choices made by the original artifact makers. The combined results of these individual sequences can provide insight into behavior patterns which are indicative of broader culturally determined traits and norms. By applying this methodological approach to a site that contains unusual or atypical MSA features, it can identify other 'loud archaeological signatures'.As noted by McBrearty (2003: 514) "one of the most difficult tasks for the prehistorian is to identify the emergence of novel behaviors." The authors suggest that a set of novel behavioral patterns is a most apt description for the results that have emerged from a recent test excavation at Rhino Cave, located within the World Heritage site of Tsodilo Hills, Botswana. This site was initially excavated in the mid-1990s (Robbins et al...
