== Removed "Co2 glacial cycles 800k" Graph == 

 I removed the "Co2 glacial cycles 800k" graph from the Sangamonian (stage) article because this graph uses stratigraphic terminology that is hopelessly antiquated, obsolete, and meaningless. I discuss in the talk section for that figure. Before this graph can be used, it needs to be revised to remove the discredited Quaternary stratigraphic terminology and have it replaced with the correct Quaternary stratigraphic terminology.
