Saw that Columbian profile and knew it instantly.
Given where it was found and the good condition, it makes sense that this was buried shortly before the great boloid event outlined by Firestone, et al.
“There are hundreds of depictions of proboscideans on cave walls and carved into bones in Europe, but none from America—until now.” However, this statement is wrong and indicative of insufficient interdisciplinary communication among researchers. Gloria Farley’s book In Plain Sight: Old World Records in Ancient America shows the petroglyphs of an elephant and hippopotamus in a site called The Anubis Caves. Given various aspects of cave markings—pictures and writing found there, it is suggested that the site in or near Oklahoma could be 3,000 to 3,500 year old. The writings seem to be north African and Celtic. This age if correct could correspond to the time of the mysterious Sea People of the Mediterranean. Her book also refers to several other finds of elephant petroglyphs. The one in the Anubis caves does not have the upsloped profile of the Columbian mammoth.
