Middle Stone Age fauna from the RS sub-member (MSA I) at Cave 1B, Klasies River Main site, South Africa

Abstract

Klasies River is an important site for the study of the evolution of Homo sapiens, understanding modern behaviour and human interaction with the environment during the Middle Stone Age. The faunal sample from the RS sub-member in Cave 1B (MSA I), dating to ca. 115 000 years ago and older, was recently analysed. The results indicate that humans were hunting a variety of prey. The most common taxa in the sample are indeterminate medium birds, indeterminate small mammals, rock hyraxes, and indeterminate medium mammals. Based on multiple lines of evidence including the presence of: cultural artefacts, shellfish, tortoises, large mammals, butchery marks, and burnt specimens; and, a lack of carnivore taxa compared to ungulates (as reflected in the low carnivore-ungulate ratio), hyena coprolites and beak damage, coupled with infrequent baboons and the absence of leopards (as reflected in the low leopard index), it is apparent that humans were the main agent of accumulation of the fauna. However, other agents of accumulation such as brown hyenas, leopards and raptors likely contributed some faunal remains, especially of smaller taxa.
