A bias toward flaked tools as the primary indicator of human activity and an ignorance of the importance of crude and opportunistic tools and portable rock art in evaluating archaeology sites leads many to err in thinking objects like these are "just rocks."
A Pleistocene archaeology and rock art scholar with most all of his experience in the "Old World" has called the Arkfeld site "The most remarkable pre-Clovis site in the United States." Hopefully this will not be lost on those who profess to be searching for evidence of the earliest Americans.
From all of the art we can say "the right eye may have been symbolic of a life portal and the left eye symbolic of a death portal." If so, this piece may be saying "the death eye of the mammoth is the life eye of the human." This notion is compatible with Duncan Caldwell's "Prey-Mother" hypothesis. The death of the mammoth may have been seen as important for human survival.
This kind of human/mammoth combination is seen a good number of postings on this blog and may also be seen in examples of parietal art in Europe.
