In my cursory search without access to all the proper academic journal sources, I can find no earlier association of the Miller Cave iconography with a widely published example about a year old from France. Why aren't the Americans studying American cave art in a world context? Or why aren't the French studying American cave art? Is it possible the Americans and the Europeans are operating in such isolated academic silos they are not capable of making connections which seem so obvious to laypersons? Is it that an "American Aurignacian" occurrence is regarded as impossible by a supposed science? I think so.
