The pendant dates to 11,o00 years ago. When I first read the article’s title, I was skeptical about “secret codes”, and I still think it’s a bit on the sensationalist side.
This pendant has connections. The lines are similar to those drawn on batons found in Asia, related to societies with shamanic, animist based religions. If the usage was as similar as the marks themselves, then the long lines may represent hunts, and the small lines that make tick marks along the longer ones may represent the number of animals taken in the hunt.
