Prehistoric Stone Tools - Archaeological Illustration of Early Human Technology #273766 (License: Personal Use)

This black-and-white line illustration shows three distinct lithic artifacts from the Paleolithic or Neolithic era. The leftmost tool is a ring-shaped axe or perforated discoid, likely hafted; the center piece is a carefully retouched bifacial flint point with serrated edges; the rightmost is a cortical scraper with a flat working edge and保留 natural cortex on the dorsal surface. Each exhibits characteristic knapping techniques such as percussion flaking and pressure retouch.

Used in educational, museum, or academic web pages about archaeology, human evolution, or ancient technology; serves to visually explain tool typology and manufacturing methods for students and researchers.
