Dangferous as it may be, here's a comment about C-14 dating. The one major reason that C-14 dating can be off (noticeably) is that the amount of C-14 in the atmosphere varies from era to era. Because of this, C-14 dating of objects since the Rise of Civilization (try ending of the Stone Age) are less accurate than times before. However, I think that some research group is busily trying to map the C-14 concentrations around the world throughout history. They're doing this by matching C-14 dates, archeological data, and (where possible) written records about types of industry predominant in different areas. orstcs!richardt "(When companion turns purple) Somehow, I don't think that's what he wanted to hear.
