Abstract
This research paper examines the stone technology of prehistoric humans, especially the use of flint. The criteria for selecting raw materials in the production of prehistoric tools, the chemical composition of siliceous rocks, and their inherent physical properties are discussed here. The mechanism of 'conchoidal fracture', the basic basis of stone tool technology, is scientifically analyzed when a force is applied to a rock. Furthermore, the study describes methods for distinguishing between natural rock fractures and artificial fractures caused by human intervention, as well as basic shaping techniques such as quartering and flaking. Another aspect of this study is identifying the age of a tool through 'patina', the chemical changes that occur on the surface of rocks. Finally, this study emphasizes that archaeology makes a significant contribution to building robust typological models for interpreting past cultural dynamics by understanding these technological limitations and capabilities.
