Before Present, in this case, refers to 900K before today. BP is indeed used for radiocarbon dating, and the baseline is 1950 (when the method was invented); but the limit on that is around 50K years, and has nothing to do with the way these were dated. And there is no confusion between gastroliths and axes.
