It is a
deer pair of antlers still attached to part of the cranium that was cut. So the animal was killed and its skull cut in a specific way in order
to maintain the two antlers.
It is known
that these “objects” were associated to masks used in shamanic ceremonies since ancient
times (some art interpretations take these practices back to Upper Paleolithic).
