A 35,000-Year-Old Ivory Tool Reveals the Lost Art of Stone Age Rope Making
Rope, twine and thread: Invisible technologies of the Stone Age

Archaeologists long overlooked rope, string, and twine because they decay, yet these soft technologies were essential. A 35,000-year-old perforated ivory baton from Hohle Fels, with spiral grooves around its holes, was used to twist cattail fibers into five meters of strong rope in just ten minutes. Such cordage enabled hafting, snares, nets, and rope ladders, reshaping daily life for prehistoric hunter-gatherers.
We're missing 90 percent-plus of what is happening during a prehistoric day, and a lot of that uses technology that we don't think about.
