The Saurians are discontent with stone. . . they fight amongst themselves in the very rare fight for a marriage or girlfriend, but they've noticed that most deaths are caused by unarmed combat or by using pin point accuracy against the eyes and then crushing of the skull, or some form of mangling. Their scales are very tough and difficult to scratch. So, the Saurians begin to search for better weapons. Eventually an ingenious Saurian discovers "bronze". . . a way to smelt copper and tin together.
