No, I'm not talking about courting strategies , I'm talking about the methods by which geologists date rocks and paleontologists date fossils. First off, I'd like to know what the different methods are. But, more importantly, I'd like to know how accurate they are...what is the margin of error on each method? Which is the most accurate method? Which is the least accurate? Any info on this is appreciated. P.S. if this belongs in some other forum, please move it, it just seemed to fit here.
