Hi, Faith24, and welcome aboard!
​
I'm no expert on racemization dating, but I am a chemist, and I can conceive of several things that might interfere with getting accurate dates from the method. Moisture content of the material being dated might be very important, and it could be pretty tricky to construct a history of that. Carbon-14 dating won't have this problem, as C-14 and C-12 will be affected essentially equally by anything water would do to them. Any slight difference in reaction rate they had could be corrected for by looking at the carbon-13 ratio with carbon-12 - C-13 is non-radioactive so it won't gradually disappear like C-14 does.

I do suscribe to Nature, but they want $32 for me to access an article of this age. I'm feeling too cheap today to do it......
