Many of the marks are geometric shapes, such as triangles or circles. Some designs appear to match those of figures seen within Paleolithic cave art from the same regions. This suggests that the symbols may have held important meanings for people then.
“It is widely understood that these designs are part of an unknown code,” Angulo said, adding that some of them might have been made exclusively for a decorative purpose. Tattoos today follow the same coda, for the most part. A lion tattoo on a man’s arm may only mean that the man likes the look, not that the lion means anything special to him.
