38,000-year-old carving includes enigmatic “punctuation” pattern | Ars Technica
There are punctuations, which form a clear pattern behind and beneath the animal. There are also "short, parallel marks" in front of the aurochs' chest. And there is a deep line that cuts straight through the center of the stone and the aurochs' body, as well as a "tunnel-like depression" right in the abdomen. Indeed this line was cut so deeply that the researchers believe it eventually caused the slab to split in two. Interestingly, analysis revealed that this deep cut was carved first, then the punctuations, followed by the aurochs. So the animal's body was drawn on top of these abstract dots and lines, and some of the dots were even joined to create the aurochs' legs, hindquarters, and abdomen. "The animal figure, executed after the creation of the deep depression, was constructed so as to integrate this feature, which seems to have an important role in the overall graphic construct," the research team wrote.

Early archaeologists believed these punctuations, which are found throughout the region, were a way of tracking phases of the moon.
