Something may be wrong. This same image is shown as a deer antler clay-roll engraving (French bâton gravé) discovered by Édouard Piette and in his collection. In several sources, including Philip Meggs' History of Graphic Design, 6th Ed., Figure 1-4:
Trouvé par E. Piette vers 1873, ce bois gravé de cervidé (un renne) semble presque banal. Pourtant, en réalisant un calque que l'on déroule, nous nous trouvons devant un chef d'oeuvre de l'art magdalénien : « La gravure aux cerfs et aux saumons ».

"Cylinder of reindeer antler (so-called baton), with carvings of reindeer and fish, Magdalenian, 20,000-10,000 BCE (National Archaeological Museum, Château de Saint-Germain-en-Laye, France). Below, modern cast showing the whole design unrolled." ru.pinterest.com/pin/20336635787932632/
It can't possibly be both a cave carving, as you suggest, and a deer antler roll form. I suspect it is the deer antler.
