For a long time, research of bone industry in archeology was disorganized and mostly limited for classification according to the tools' shape, from which the function was deduced. This method was frequently imprecise and complicated for bone artifacts as well as for chipped stone artifacts. In the last few decades, scientists have tried to apply to the bone industry microwear analysis, which was then successfully applied to the chipped industry. Microwear analysis can help us recognize usewear traces and give information about the manufacturing and functioning of the tools. Using microscopes can prove which artifacts were manufactured by humans and which were simply broken in order to get marrow, and which were bitten by predators. The goal of this research is to expose the functions of tools and artifacts, which are previously unclear, by use of experimental archeology and use-wear analysis, primarily for artefacts known as bone skates (or bone ice skates), which are classified only according to their shape (and often incorrectly). In many foreign countries, the method and application of microwear analysis is increasingly popular. However, in the Czech Republic, it is largely overlooked. Therefore, we would like to extend the sample of possible contact materials and contribute to the progress of...

The goal of the thesis is to find the way how to apply use-wear analysis as well as functional analysis to archaeological assemblages of selected artefacts from Central European archaeological contexts, namely lithics (chipped stone artefacts) and obtain the greatest potential from the analysis. Thesis consists of: current state in the field of functional studies research worldwide, method of use-wear application in connection with material science knowledge, especially tribology. Use-wear analysis is applied to the selected lithic artefacts from Paleolithic to Eneolithic Periods. The results of this work are based on the following microscopic approaches: low power approach (LPA), high power approach (HPA), scanning electron microscopy (SEM) and confocal laser scanning microscopy (CLSM). There are described and stated differences in potential of above mentioned approaches in connection with specific archaeological artefacts (assemblages of artefacts). The question answered in the conclusion is how to apply the above mentioned methodological approaches in application to various archaeological materials (period, number, context etc.) to obtain the greatest informational potential from the material analysed. Work is concluded with specific terminology from the field of tribology and use-wear analysis...
