cutmarked

Cutmarked refers to a characteristic found on archaeological artifacts, particularly stone tools, that indicates modification by cutting. These marks are typically observed under magnification and are the result of the abrasive action of stone on stone during the process of shaping or sharpening a tool. They are distinct from natural fracture surfaces and can provide valuable insights into the manufacturing techniques employed by ancient peoples.

The presence and morphology of cutmarks can help archaeologists determine the type of material used for cutting, the angle of application, and the directionality of the force applied. This information is crucial for understanding the technological capabilities and cognitive processes of past societies. For example, the regularity and depth of cutmarks might suggest a standardized tool-making process, while the nature of the marks could indicate whether a sharp edge or a more abrasive surface was used.

Analysis of cutmarks is a specialized field within lithic analysis. Researchers examine these microscopic features using tools like optical microscopes and scanning electron microscopes to document their patterns. Comparing observed cutmarks to those produced experimentally on similar materials can help in identifying the specific lithic technologies used. This detailed analysis contributes to a broader understanding of human prehistory, including patterns of resource use, technological innovation, and the development of complex toolkits.
