12,000-year-old spindle whorls and the innovation of wheeled rotational technologies.

'The wheel and axle' revolutionized human technological history by transforming linear to rotary motion and causing parts of devices to move. While its ancient origins are commonly associated with the appearance of carts during the Bronze Age, we focus on much earlier wheel-shaped find-an exceptional assemblage of over a hundred perforated pebbles from the 12,000-year-old Natufian village of Nahal Ein-Gev II, Israel. We analyze the assemblage using 3D methodologies, incorporating novel study applications to both the pebbles and their perforations and explore the functional implications.

Artifact3-D: New software for accurate, objective and efficient 3D analysis and documentation of archaeological artifacts.

The study of artifacts is fundamental to archaeological research. The features of individual artifacts are recorded, analyzed, and compared within and between contextual assemblages. Here we present and make available for academic-use Artifact3-D, a new software package comprised of a suite of analysis and documentation procedures for archaeological artifacts.
