Ancient Innovations Pressure flaking is a method of forming points, grooves, and notches on stone tools in which a tool is pressed up against another stone, instead of striking it. It has been thought to be a fairly recent innovation, arising in the Upper Paleolithic 20,000 or so years ago. Mourre et al. (p. 659), show that tools from Blombos Cave, dating to about 75,000 years ago, have grooves and patterns resembling production by heat treatment followed by pressure flaking. Replication… 

Early evidence of San material culture represented by organic artifacts from Border Cave, South Africa

Reappraisal of radiocarbon age estimates through Bayesian modeling, and the identification of key elements of San material culture at Border Cave, places the emergence of modern hunter–gatherer adaptation, as the authors know it, to ∼44,000 y ago.

Middle Stone Age Bifacial Technology and Pressure Flaking at the MIS 3 Site of Toumboura III, Eastern Senegal

Over the past decade, the increasing wealth of new archaeological data on the Middle Stone Age (MSA) in Senegal and Mali has broadened our understanding of West Africa’s contributions to cultural

Stone heat treatment in the Early Mesolithic of southwestern Germany: Interpretation and identification

It is found that an opportunistic low-investment procedure was used to heat stone, probably relying on the use of the above-ground part of regular camp-fires, and that the traditionally used macroscopic criteria cannot be unambiguously used to identify heat treatment in assemblages made from Jurassic chert.

Technological behavior of the early Late Pleistocene archaic humans at Lingjing (Xuchang, China)

The period approximating 100 ka relates to Middle Paleolithic or Middle Stone Age technological behaviors that are generally characterized by prepared core technology, an expanding range of retouched

Further Evidence of Organic Soft Hammer Percussion and Pressure Retouch from Lingjing (Xuchang, Henan, China)

ABSTRACT Opinions on the nature and distinctiveness of the Chinese Paleolithic differ between those who assign early Late Pleistocene lithic technologies to some peculiar facies of the Middle

Pressure flaking to serrate bifacial points for the hunt during the MIS5 at Sibudu Cave (South Africa)

The suite of technological and functional data pushes back the evidence for the use of pressure flaking during the MSA and highlights the diversity of the technical innovations adopted by southern African MSA populations.

Two million years of flaking stone and the evolutionary efficiency of stone tool technology

The long-term trends identified in this study inform us that the evolutionary efficiency of stone tool technology was not inherently in advanced tool forms and production techniques, but emerged within the contingencies of hominin interaction with local environments.

Technology and Function of Middle Stone Age Points. Insights from a Combined Approach at Bushman Rock Shelter, South Africa

Edge convergence, which is typical for pointed tools, is a major morphological feature contributing to the definition of the African Middle Stone Age (MSA). The multifaceted character of points might

Fire As an Engineering Tool of Early Modern Humans

Replication experiments and analysis of artifacts suggest that humans in South Africa at this time, and perhaps earlier, systematically heated stone materials, including silcrete to improve its flaking properties in making tools.
