I'm taking an AP World History course, and I am making a basic world history time line!. I need to know the ages, periods, and eras (Stone Age, Precambrian Era, ect) I need to know all the bits and pieces that the history of the world has been broken into since the beginning of time!. Not just to 5000 B!.C!.E!., but far back as at least 2!.5 million B!.C!.E!. Does anyone know of a website where I can get this information or a book that has what I'm looking for!?Www@QuestionHome@Com
