Second, "various plants have differing abilities to exclude significant proportions of the C-14 in their intake. This varies with environmental conditions as well. The varying rates at which <SUP>14</SUP>C is excluded in plants also means that the apparent age of a living animal may be affected by an animal's diet.  An animal that ingested plants with  relatively low <SUP>14</SUP>C proportions would be dated older than their true age."<ref>Nondestructive Testing (NDT) Resource Center, "Uncertainty in Carbon Dating"[http://www.ndt-ed.org/EducationResources/CommunityCollege/Radiography/Physics/carbondating.htm]</ref>

Carbon dating cannot give accurate numbers if the sample is younger than 150 years or older than 50,000 years. The inaccuracy for material younger than 150 years is ascribed to changes in the ratio of <SUP>14</SUP>C to <SUP>12</SUP>C in the atmosphere.<ref>http://www.talkorigins.org/indexcc/CD/CD011.html</ref>

Additional anomalous results from carbon dating, which reinforce its limitations, include the inability to date carbonate rocks, which confound the science behind the dating technique.
