Some features make experts think it's a female skull. The grooved shows three characters; one on the forehead wears a bird mask and the body appears stark, showing part of its skeleton. In the direction that the character looks, he seems to be taking off his mask or handing it over. The last one has a knee on the floor and wears a headdress shaped like an animal, possibly a deer, and picks something up from the ground or hands it back.
