According to Figuier during the Reindeer Epoch (outdated, unused term), bone and reindeer's horn displaced flint. A caveman or troglodyte is a stock character based upon widespread concepts of the way in which early prehistoric humans may have looked and behaved. The term caveman, sometimes used colloquially to refer to Neanderthal people, originates out of assumptions about the association between early humans and caves, most clearly demonstrated in cave painting or bench models.
