The objective of this study was to determine if visible reflectance spectroscopy and quantitative colorimetry represent viable approaches to classifying the heat treatment state of silcrete. Silcrete is a soil duricrust that has been used as toolston

There are multiple hypotheses for human responses to glacial cycling in the Late Pleistocene, including changes in population size, interconnectedness, and mobility. Lithic technological analysis informs us of human responses to environmental change

Youngest Toba Tuff glass shards found together with evidence of human occupation at two archaeological sites from the southern coast of South Africa indicate that early modern humans thrived in this region despite the eruption of the Toba supervolcan

The origins of complex projectile weaponry provides insight into cultural and biological changes associated with the origins and spread of modern human populations. Middle Stone Age backed pieces are often thought to be components of such armaments,

The heat treatment of stone to enhance flaking attributes was an important advance in the adaptive toolkit of humans and a major step in pyrotechnology. The earliest evidence for this is the heat treatment of silcrete ~164 ka at the Middle Stone Age

The Palaeo-Agulhas Plain (PAP), when exposed, presented Middle Stone Age (MSA) foragers at Pinnacle Point (PP) on the South Coast of South Africa with new sources of raw materials to make stone tools. Sea-level fluctuations and the changing size of t

Open-air Middle Stone Age (MSA) contexts in southern Africa have received relatively little research attention compared to caves/rock-shelters. MSA caves/rock shelters can provide long sequences of MSA behaviors dominated by residential activities in

This paper presents the results of a series of experiments for the identification and analysis of fire modified rock (FMR). FMR is a common but frequently overlooked artifact type. Experiments were conducted simulating the effects of different hypoth

Changes in the frequency of stone tool raw materials are observed in stone age records across the world and throughout time. These are normally interpreted as showing important changes in human behavior. Brantingham (2003) proposes a neutral model to
