Robust Middle Paleolithic flint side-scraper showing clear deliberate workmanship. One lateral edge forms a well-defined working zone created by sequential, unidirectional removals, characteristic of Mousterian stone tool technology. The opposite face retains a large natural cortex surface used as an ergonomic grip. The piece shows a preserved platform area, strong patination, and a mature archaeological surface consistent with long prehistoric exposure. Condition: Very good archaeological condition.
