A 2025 study by Courtney, Francesco d'Errico, and colleagues examined 22 artifacts with up to 2,840 total marks. Nine were proposed as artificial memory systems. Mark orientation varied meaningfully: butchery marks were often oblique to bone axes, art fell in a middle range, and suspected notation marks approached roughly 80 degrees to the surface.
2025 d'Errico study of 22 artifacts distinguishes butchery, art, and notation marks

Key facts
- A 2025 study by Courtney, Francesco d'Errico and colleagues examined 22 archaeological artifacts with as many as 2,840 marks
- Nine artifacts were proposed to have artificial memory systems
- Butchery marks showed the greatest variation in orientation, often oblique to the long axis of the bone
- Depictional and abstract engravings occupy an intermediate range
- Suspected artificial memory systems had lowest variation with marks approaching a near perpendicular angle of roughly 80 degrees
