'Mammoth right profile with human face carved on its posterior'
Stacy Dodd and Rod Weber find, The Old Route 66 Zoo Site, #23JP1222
Close up of human face along with illustration of features carved in the stone
The 'mammoth with human or feline face at its posterior' rock art motif in North America was first described here and is seen in many examples on this blog.
This sculptural 'template' or 'scheme' of a mammoth/human combination must have had a culturally associated meaning for the people who made them. Earlier this year I speculated it may illustrate a scene from a Paleolithic proto-Polyphemus tale.
