Both stone age Europeans and stone age Americans engaged in the cultural practice of making over-sized decorative spear-points, presumably for a religious or ceremonial use. Both groups also put them into holes, covered them in red ochre and buried them.
Some of those have been unearthed by archaeologists in both Europe and America, and are dated to be between 10,000 years old in North America and 20,000 years old in Europe.
