The age of the carbon in the rock is different from that of the carbon in the air and makes carbon dating data for those organisms inaccurate under the assumptions normally used for carbon dating.

Benoit de Maillet (1656-1738) wrote that fish had become birds, mammals and men.This Norwegian spruce's 9,550-year-old root system is credited to the conifer's "ability to clone itself." See how scientists determined its age and why it's expected to keep living for a very long time.You've heard about people seeing their lives flash before their eyes.Carbon dating is used to determine the age of biological artifacts up to 50,000 years old.This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils (like those of the dinosaurs alleged to be millions of years old).Hence we can use datable rocks to put dates on fossil species; and then we can use the fossil species to put dates on other rocks which would otherwise be difficult to date.
